Parochial cooperation in wild chimpanzees: A model to explain the evolution of parochial altruism

Leave a reply

Lemoine, S. R. T., Samuni, L., Crockford, C., & Wittig, R. M. (2022). Parochial cooperation in wild chimpanzees: A model to explain the evolution of parochial altruism. In Philosophical Transactions of the Royal Society B: Biological Sciences (Vol. 377, Issue 1851). Royal Society Publishing. https://doi.org/10.1098/rstb.2021.0149

This is an exceptional paper. The authors define “parochial altruism” as taking individual costs to benefit the in-group and harm the out-group, and propose a model for the evolution of parochial altruism. The model applies to chimpanzees, but the idea is that this model might perhaps also explain how parochial altruism evolved in humans.

For this purpose, the authors review a vast number of papers in the field of cooperation and aggression in wild chimpanzees (and, to some extent, other animals) .

The model they propose is a complex one. It is relevant, for the issues we talk about in this blog, that the authors propose a positive feedback loop between aggressive encounters with external groups, on the one hand, and collaboration and cohesion within the group, on the other.

For example:

  • “In-group solidarity tends to increase in response to out-group conflict, suggesting a causal link between out-group threat and in-group cohesion” (p. 2).
  • “Evidence across taxa, including birds and mammals, demonstrate an immediate increase of in-group cohesion and affiliation following out-group threat, pointing towards the link between out-group conflicts and in-group favoritism” (p. 2).
  • “Cooperation is key in maximizing the chances of beneficial outcomes of out-group conflicts” (p. 5).
  • Group conflicts favor “the emergence and maintenance of cooperation among non-related individuals, the maintenance of strong social ties, in-group favoritism and hostility towards out-group members” (p. 7).
  • “The highly structured and collective border patrols and large coalitionary attacks observed in chimpanzees indeed suggest strong links between group-level cooperation and out-group threat” (p. 8).

All this is important and relevant for the origin of the state, as explained by my mentor, Juan Samaja. Individuals compete against each other (internal war), but the pressure of the external threats makes them unite against the common enemy (external war); this threat is one of the keys to the birth of the state, as already explained in Plato’s Republic.

Another interesting aspect is that the paper establishes a link between reciprocity and what we call “community”. “The accumulation of bonded relationships, embedded within a social network, provides a path by which group-level cooperation occurs. The hypothesis that direct reciprocity constitutes a mechanism enabling solving collective problems finds support in chimpanzees where regular social interactions within a community cement a sense of common belonging (a common affect), enabling group-level collective action and avoidance of defection” (p. 8). This of course works only for local groups and small-scale cooperation; large scale cooperation requires other normative and symbolic frameworks (a flag, a national narrative, etc.)

For those of you (readers) who follow my musings in this blog about the epistemological impact of social coordination, it is interesting to note that chimpanzees engage in border patrols, where they move along the edges of their territories to monitor and defend their boundaries. They check for signs of intruders, such as the scent of unfamiliar individuals or the sound of other chimpanzee groups in the area. If they detect signs of intrusion, they often engage in displays of aggression, such as vocalizing loudly, throwing rocks and branches, or charging at the perceived threat. Now, this behavior might be the oldest precursor of the cultural institution of “boundary”. This institution, incidentally, is the one that philosopher John Searle uses as an example to explain the very notion of “institutions” (differentiating a wall that encircles a village as a physical barrier that can’t be crossed from a symbolic stone that marks the limit of a village and shouldn’t be crossed). Once we humans learned how to play the game of boundaries on an institutional level, we started to demarcate boundaries on the epistemological level. Ancient Rhetoric is born as an exercise to argue for the property of land, to have the limits of one’s property recognized. In Plato’s Republic, the limits of the city are delineated hand in hand with the limits of the citizen (both are defined almost in the same way), as well as the boundaries of the concept (of the Good, for example). Even Kant’s transcendental deduction follows to the detail the format of a legal deductio aimed at demarcating the territory and the boundaries of a state (Kant applies this format to demarcate the limits… of pure reason).

Exploring the first possessor bias in children. Nole & Keil.

Very interesting and insightful paper. The authors set out to explore an apparent contradiction: on the one hand, very young children (even 2-year-olds in some studies) are adept at linking property to owners. On the other, there is research that reports that children systematically conserve property with the first possessor, even after a legitimate transfer of the property to a second possessor (e.g., after a sale, a present).

This study tests children, ages 7 through 10, for the presence of a first possessor bias in first- and third-person situations, and for different types of property transfers (gift, sale, loss, etc.)

A first experiment used third-person scripts depicting different types of property transfers. The authors found that seven- and eight-year-olds, but not older children, exhibited a first possessor bias. “Children under 9 commonly inferred that first-possessors maintained ownership of property, even after they unambiguously transferred the property to another person.” “Experiment 1 reveals that the first possessor bias influences ownership attributions among children age 7 and 8, but not 9 and 10.” “Experiment 1 demonstrates that the first possessor bias persists much longer into development than previously thought.” “This result replicates previous findings and expands upon those studies, suggesting that the first possessor bias influences a wider swath of property transfers than previously demonstrated, and that children’s ownership attributions are affected by this bias for longer than previously reported.”

At the same time, they found that the bias was greatly attenuated or absent when property transfers were presented in a first-person context. This was demonstrated in a second experiment, in which “Participants were always framed as the recipients or second actor in each scenario, and they were asked who owned the target object at the end of each trial. Participants indicated that the item either belonged to them or to the experimenter.” “In Experiment 2, all age groups demonstrated attenuated endorsement of the first possessor with respect to stealing (…) context powerfully influences intuitions about property transfers in both children and adults.” “Experiment 2 provides an explanation for the mismatch between intuitions that children do understand property transfers early in development, and findings that children’s intuitions about property transfers are fundamentally biased. Specifically, manipulating the presentation context (i.e., presenting transfers in a first-person context) resulted in children generating adult-like ownership attributions for typical property transfers such as giving and selling.”

One important consequence for the study of the development of ownership is that there is a big gap between first- and third-person reasoning. Thus one can reconcile research by Rossano, Rakoczy, & Tomasello (2011) among others, that shows that 3-year-olds recognize property rights when laboratory situations resemble real-life situations, with other studies which use third-person narratives and find errors in reasoning about property rights in children until at least age 10 (Kim & Kalish, 2009).

The authors speculate that the first-possessor bias has adaptive value: “it is possible that young children are less adept at reasoning about property transfers because these events are more ambiguous, and more likely to be intervened upon, than non-transfer scenarios. Given these circumstances, maintaining strong bonds between owners and their property may be a more functional approach for young children than reasoning in a more adult-like and “accurate” manner.”

Susan Gelman on children’s preference for unique owned objects

Leave a reply

Gelman, S. A., & Davidson, N. S. (2016). Young children’s preference for unique owned objects. Cognition. https://doi.org/10.1016/j.cognition.2016.06.016

This is an incredible and profound study on children’s attachment to objects, with implications both for cognitive and emotional development. It’s also a study that amazes me for the amount of work it required from researchers (who had to find brand-new replicas of more than 100 children’s attachment objects).

The experimental design is quite simple. Researchers asked 36 three-year-olds to choose between two toys for either themselves or the researcher: an old (visibly used) toy vs. a new (more attractive) toy matched in type and appearance (e.g., old vs brand-new blanket). Focal pairs contrasted an old toy that belonged to the child with a matched new object; control pairs contrasted toys the child had never seen before.

The conclusion of the study is that, by 3 years of age, young children place special value on unique owned objects. Children prefer their original objects to newer, better versions, but only in the case of the focal pairs (with their objects of attachment) and not with the control pairs (objects the child had never seen before). These findings are consistent with the view that possessions are extensions of the self.

In addition, these preferences hold for “sleep” objects (blanket, pillow) and toys representing an animated character (dolls, action figures) but not for inanimate objects (a car, a toy hammer, etc.) Uniqueness is valued for sleep objects and animate toys, but not for inanimate toys. Moreover, in 30 out of 31 cases, attachment objects had a proper name. Ownership, attachment and anthropomorphism (eyes, animated features, soft or furry texture) all combine to enhance children’s preferences for their own objects.

In addition, children seemed to understand that their special objects had value for them only in so far as they share a history with the object. That is, they did not attribute the researcher the same preference for the old (attachement) object. In this sense, they seem to understand the subjective nature of value.

The results are remarkable, among other things, because of the understanding of the abstract ownership relationships, the distinction between appearance and reality and the perspective-taking abilities involved in children’s responses. The authors also emphasize how attuned any child can be to minor features of an object that indicate that it is her unique object and not a substitute.

These findings also offer a different (experimental, cognitive) perspective on the phenomenon of “transitional objects,” first described by Donald Winnicott in the 1950s.

A remarkable study indeed.

Romantic love is universal

Leave a reply

Fletcher, G. J. O., Simpson, J. A., Campbell, L., & Overall, N. C. (2015). Pair-Bonding, Romantic Love, and Evolution: The Curious Case of Homo sapiens. Perspectives on Psychological Science, 10(1), 20–36. https://doi.org/10.1177/1745691614561683

This is a paper about the evolutionary function of romantic love. Against common ideas that romantic love is purely a social and cultural construct, the authors show that some form of romantic love exists in virtually any culture on earth and that (as ancient myths and folk tales prove) it has existed since immemorial times.

Love is an important topic for a blog concerned with ownership, because loving relationships tend to be possessive. Even more, individuals in formal relationships (married, engaged, etc.) argue about their exclusive rights to the sexual enjoyment of their partners in a way that resembles an owner defending her exclusive rights to a certain property. Moreover, when they feel such exclusivity is threatened, they can be overwhelmed by emotions such as jealousy or rage.

The paper quotes several scholars (mainly Shaver and Hazan) who postulate three-dimensional theories of love that I find quite appealing. Romantic love is composed of attachment, caregiving and sex; or passion, intimacy and commitment. They also mention the striking similarity between the behavioral manifestations of parent–infant love and romantic love, which suggests that evolution may have borrowed these ancient bonding mechanisms, originally evolved in mammals to bond mothers to their offspring, and applied them to men and women in the context of romantic pair-bonding.

Contra Locke

(…) On the contrary, Nozick writes, there are instances where by mixing one’s labor with something in nature, one loses one’s labor without making any gain: “If I own a can of tomato juice and spill it in the sea so that its molecules (made radioactive, so I can check this) mingle evenly throughout the sea, do I thereby come to own the sea, or have I foolishly dissipated my tomato juice?” The answer is obviously the latter, he argues.

Use, possession, ownership. An ongoing conversation with P. Kanngiesser

Leave a reply

Recently Patricia Kanngiesser sent me a copy of the intro to her doctoral thesis, “Biological and Developmental Origins of Ownership Concepts.” I really enjoyed reading it. It’s extremely well written and well argued. She provides a number of new insights on the development of ownership with great clarity. It’s just brilliant.

One of the important topics Patricia addresses is the conceptual distinction between possession and property. She argues that, while possession presupposes physical proximity between possessors and their things, ownership holds even in the owner’s absence. Possession requires the simultaneous presence of owners and their objects, ownership does not.

Based on this distinction and on extant research on ownership in animals and humans (children and adults), she claims that animals show only possession-related behavior that is crucially dependent on an animal being in physical proximity to a thing. In other words, ownership is absent in animals; animals display rudimentary precursors of ownership-related behaviors only.

“While animals show attachment to things such as territories, food, and mates, evidence for recognizing possession and respecting others’ possessions irrespective of factors such as dominance rank or competitive advantages is sparse. Apart from one rare example of respect for possession of females in baboons, most respect for possession seems to derive from the fact that possessors manage to avoid dominant rivals (e.g. by carrying possession away). Finally, universal social rules regarding ownership are absent from animal societies. While attachment to things could form a biological basis for ownership-related behaviors in humans, an ownership concept that encompasses recognition and respect of ownership as well as a complex web of social rules is probably the unique product of a human socio-cultural environment.” (Patricia Kanngiesser, doctoral thesis).

Up to here I summarized Patricia’s position, and I agree with her. Now, it must be noted that even animal possession is not a two-term relationship (between an individual agent and a thing) but always presupposes a social context. There are possession conflicts because there are individuals competing for objects and for recognition, or for “prestige” as Philippe Rochat would say. PK notes that “about 75% of young children’s conflicts with peers revolve around the possession of objects” and that “21-month-olds often view a toy as more attractive after another child has named or touched it” (Hay & Ross, 1982). Objects become desirable because they are desired by other children; once a child children obtains an object, she wants to be recognized as possessor by other children; she now has exclusive access to the object and can exclude other children. As PK writes, “it is thus conceivable that conflicts concerning the possession of objects are also driven by social motives such as establishing social relationships and exerting social influence.” This, again, suggests not a dual relationship agent-object but at least a triadic relationship agent-object-agent.

Furthermore, PK also notes that “prior possession presents an advantage in conflicts over objects”, a finding corroborated many times both with young children and with some animal species. Now, if current possessors tend to win possession conflicts, it’s because other agents can identify them as possessors. Which again suggests not a dual relation agent-object but a triadic relation where other agents can identify possessors and interact with them accordingly. In this incipient relationship between a non-possessor and a possessor, even if “universal rules” are still absent (as PK argues), there is something like a proto-rule at work: perhaps for strategic reasons that can be modeled in terms of game theory (costs of trying to take an object from a possessor are high), perhaps for efficiency reasons (groups are more stable when possessors are not attacked and conflicts are minimized), current possession is respected, which might be a precursor of institutional or conventional rules such as the prior possession rule (which establishes that prior possession is a justification for ownership).

Therefore, I stick with my position that you need to discriminate three different categories:

– Use: dual relationship between an agent and an object (food, toy, instrument, etc.)

– Possession: triadic relationship agent-object-agent that requires one agent (called the possessor) physically controlling the object, while the other agent is excluded from this relationship. In this scenario, some proto-rules start to play out.

– Ownership: a relationship between agent and object that is not based in physical control but in normative rules (“universal” rules, as PK calls them). The title of owner gives the owner privileged access to the object and, in general, a number of rights and duties.

 

Psychological ownership

Leave a reply

Pierce, J. L., Kostova, T., & Dirks, K. T. (2002). The state of psychological ownership: integrating and extending a century of research abstract. Review of General Psychology, 7(314), 1–35. http://doi.org/10.1037/1089-2680.7.1.84

Remarkable article on the psychology of ownership. This is something different from what I’m used to; it’s something I wasn’t expecting: a general psychology approach to possessive behavior that aims at taking into account biological and cultural, individual and social, affective and cognitive components.

By “psychological ownership” the authors understand: a) our sense of possession, what we feel and mean when we say “mine”, b) the object of ownership (or “target”) that becomes part of the extended self of the owner, c) a cognitive-affective complex.

The authors distinguish between the motives or roots of ownership, and the routes through which psychological ownership emerges. The motives or roots include:

  1. efficacy and effectance: possessions are important to individuals because they are instrumental for exercising control over the physical environment and over people.
  2. self-identity: possessions serve as symbolic expressions of the self.
  3. having a place to dwell: importance of having a secure base, a refuge, a shelter in the world.

My only criticism is that sometimes the language of the paper is somewhat vague. Ownership is a word with many uses and varied meanings. We may feel that we own a ball, a car, an idea, a job, a certain position in the family, in an organization or even a nation. Is the meaning of “owning” the same in all these cases? The authors claim that “when individuals feel ownership for a social entity (e.g., family, group, organization, or nation) they are likely to engage in citizenship behaviors toward that entity”. Yet we usually say that we belong to the group, organization or nation, not that it belongs to us. The meaning of belonging, owning and possession are not probably the same as when we talk about owning an object. The construct “ownership” is more complex and multifaceted than the authors assume; the meaning of ownership varies with the target of ownership and other factors. This potential criticism is not discussed in the paper.

Overall, an interesting and thought provoking article. In addition, the authors have done an extensive review of the literature and there are many intriguing quotations. For example, I should check W. James (1890) who apparently establishes a relationship between “me” and that which is considered “mine”.

Carol Rose on the moral subject of property

Leave a reply

Rose, C. M. (2007). The Moral Subject of Property. William and Mary Law Review, 48(5), 1897–1926.

In this beautifully written article, Carol Rose makes the argument that although property arrangements might seem unfair or unjust in many respects (how it is acquired, how it is distributed across society, its effect on the commoditization of sacred or moral aspects of social life), the institution of property is nevertheless beneficial for society at large insofar as it creates stability and incentives for individuals to take care of their property, invest, trade and create more value for society at large in the long run. So even when arrangements are not perfect in many specific cases (because they have morally questionably implications), it’s better to tolerate these shortcomings and to apply the established rules of ownership acquisition and distribution, because “property, as an institution, requires stability in people’s expectations about their own and other people’s claims.”

The article also contains a couple of nice quotes about one of my favorite topics: the relationship between associative and strict reciprocity: “Gift exchange cements community bonds-from a community of two on up to many more-keeping all the participants in a vague but nevertheless socially and emotionally charged condition of mutual give and take.” “(…) Gift giving differs from market exchange because through gifts, each party engages in imaginative participation in the life of the other, helping to cement relationships.”

Possession as the origin of property

Leave a reply

Rose, C. M. (1985). Possession as the Origin of Property. Faculty Scholarship Series. Paper 1830.

Fascinating, beautifully written article by Carol Rose explaining the relationship between possession (especially first or prior possession) and ownership from the point of view of legal theory.

Many psychologists investigating ownership in children have tried to disentangle first possession from other principles such as invested labor. Also, psychologists have tended to consider possession as a kind of direct, physical relationship between a person and an object. Rose, however, provides reasons to mistrust those positions and makes clear that possession is much more complex than common sense dictates, for three reasons at least:

1) Legal decisions that supposedly applied a first possession doctrine (e.g., the famous Pierson v. Post case) incorporate other principles as well, such as “reward to useful labor”. Actually, John Locke’s labor theory of property can be seen as very close and akin to the first possession principle. He makes it clear that it is the first agent who takes control of a natural resource through her work that gains ownership over it. He uses the simple example of picking an apple: the apple becomes mine when I pick it because I have added my labor to it and made it my property. Notice that, in this case, the added labor is minimal, and the crucial factor is that I picked the apple before anybody else. First possession and labor theories of ownership are similar and related to each other; they even imply each other.

2) Possession is not a direct grasping or grabbing of an object. Possession only takes place in the context of intersubjective conflict, or at least competition and potential conflict. Although there are precursors of possessiveness and territoriality in animals, human possession is not a purely natural, physical relationship between a person and a thing. Rather, it is a social act that follows proto-institutional or institutional (in Searle’s sense) rules.

3) Among those social and proto-institutional rules, the rules establishing what counts as giving public notice of an act of possession play a crucial role. For instance, what does a conqueror need to do in order to announce to the world that she has discovered virgin territory and therefore has a legal claim over it?

According to Rose, “common law defines acts of possession as some kind of statement. As Blackstone said, the acts must be a declaration of one’s intent to appropriate.” “Possession now begins to look even more like something that requires a kind of communication, and the original claim to the property looks like a kind of speech, with the audience composed of all others who might be interested in claiming the object in question. Moreover, some venerable statutory law obligates the acquiring party to keep on speaking, lest he lose his title by “adverse possession.”

Possession then requires the possessor to perform certain speech acts (in the technical sense this term has for speech act theory).

I quote Rose again:

“Possession as the basis of property ownership, then, seems to amount to something like yelling loudly enough to all who may be interested. The first to say, “This is mine,” in a way that the public understands, gets the prize, and the law will help him keep it against someone else who says, “No, it is mine.” But if the original communicator dallies too long and allows the public to believe the interloper, he will find that the interloper has stepped into his shoes and has become the owner.”

“Similar ideas of the importance of communication, or as it is more commonly called, “notice,” are implicit in our recording statutes and in a variety of other devices that force a property claimant to make a public record of her claims on pain of losing them altogether. Indeed, notice plays a part in the most mundane property-like claims to things that the law does not even recognize as capable of being reduced to ownership. “Would you please save my place?” one says to one’s neighbor in the movie line, in order to ensure that others in line know that one is coming back and not relinquishing one’s claim.”

“Thus, it turns out that the common law of first possession, in rewarding the one who communicates a claim, does reward useful labor; the useful labor is the very act of speaking clearly and distinctly about one’s claims to property.”

 

 

Children see property as nonfungible

Leave a reply

 

McEwan, S., Pesowski, M. L., & Friedman, O. (2016). Identical but not interchangeable: Preschoolers view owned objects as non-fungible. Cognition, 146, 16–21. http://doi.org/10.1016/j.cognition.2015.09.011

This is another great article by Ori Friedman’s team. They did three experiments to find out whether children see owned objects as fungible (i.e., as replaceable or interchangeable). In Experiment 1, children considered an agent who takes one of two identical objects and leaves the other for a peer. When considering a scenario where a boy took one of two identical objects home, and left the other for a girl, preschoolers viewed his behavior as more acceptable when he took his own item, rather than the girl’s.

In Experiment 2, children considered scenarios where one agent took property from another. When considering a scenario where a boy deprived a girl of her balloon, preschoolers judged it acceptable for the girl to take back her own balloon; but they judged it unacceptable for her to take the boy’s balloon, even though it was the only balloon available to compensate her.

Finally, in Experiment 3A and 3B, children considered scenarios where a teacher could give a child either of two objects to play with—an object that the child had recently played with, or another object that looked the same. When considering a scenario where a teacher could give a boy one of two identical-looking balls to play with, preschoolers were more likely to say she should return the ball that the boy had previously played with when it belonged to him, compared with when it was her own.

These findings indicate that children see property as non-fungible.

Previous studies showed that children at these ages show concern for owners’ rights to an object. McEwan et al.’s findings extend knowledge by showing that these concerns persist even when an identical replacement is available to the other. The fact that children at these ages already show intuitions of non-fungibility indicates that such intuitions are an early development, and perhaps foundational in people’s reasoning about ownership. People view ownership as granting people rights to particular objects (i.e., rather than to objects of a certain type).

These are all very relevant and important findings that add detail to current knowledge about the development of ownership.

One conceptual doubt. The fact that children say that it’s not ok to take the perpetrator’s object may not mean that children literally see identical objects as interchangeable. In my opinion, this last statement presupposes a “physicalist” view of the world, understood as a collection of free floating objects with certain physical characteristics that make them different or identical, and placed in certain positions within a 3D space. An alternative view is that children, when they respond to the interviewer, are judging the actions and intentions of the characters, in the context of a social situation that includes objects. And, as Gelman says, objects have histories. So children may think something like “it’s not ok to take someone else’s property even if they took yours first”. It is also more likely that they think in terms of particular objects, not in terms of classes or categories of objects. So the concepts of “identical” or “interchangeable” may not play a role in children’s reasoning. Also, the difference between responses to the balloon situation and the cookie situation might be due to the fact that children take into account the actions of the perpetrators, and perhaps her intentions. It’s not the same popping a balloon accidentally than eating a cookie purposefully.

Great article.

To own your own life

Leave a reply

Texts #16 & #17

Here is a brief comment about a couple of books I’ve read lately. I’ve come to the conclusion that the topic of ownership is underrated, and that an examination of our lives helps us recognize that ownership is central to our everyday existence and to our human condition in general. To own oneself seems to be the core of our existence as persons. Before we can become masters of the objects around us, we need to take possession of ourselves. Self-ownership is something that we tend to take for granted (and therefore we don’t talk about it).

The intuition of the centrality of self-ownership is presupposed by different philosophical and psychological texts. It can be traced in Freud’s doctrine of narcissism and self-eroticism,  Heidegger’s concept of Eigentlichkeit, Plato’s (and Kant’s) insistence on self-government, Nietzsche’s comments on freedom. All these authors seem to believe that the individual needs to own herself, to govern herself, to be her own sovereign, in order to exist. (Depending on the author and the context, this might be: to have a body, to be a person, to be authentic, to be free, just, or happy).

Literature also plays with self-ownership… and the lack thereof. For example, there is Selva Almada’s Chicas Muertas, which narrates the murders of four young women in Argentina in the 80s, and the author’s journey to find traces of their lives and reconstruct their deaths. Above all, Almada tries desperately to recover the victims’ voice. This makes you realize that, in the case of gender violence and extreme abuse, the victim loses control over basic things we take for granted in our everyday life: her voice, her body, her life. Someone else has taken hold of those basic aspects of a person’s existence.

To mention a very different book now, but one also written by a young contemporary and talented woman, there’s Nicole Krauss’ the history of love, which tells the story of Leo Gursky (and Alma, and her mom and brother…). Leo is a man that has lost everything, basically as a consequence of the Holocaust. He has lost his village, his country, his family, the woman he loved, the book he wrote, the contact with his only child. The result is half-a-man, a man that sees his own existence as diminished because of his losses. A man that is alive but who doesn’t exist, because he owns nothing.

I don’t want to elaborate about these points excessively, but please read the books and you’ll see I’m right.

Kanngiesser & Hood on children’s understanding of ownership rights for newly made objects

Leave a reply

Text #14

Kanngiesser, P., & Hood, B. M. (2014). Young children’s understanding of ownership rights for newly made objects. Cognitive Development, 29(1), 30–40.

This is a great paper. To begin with, Kanngiesser & Hood make a beautiful, succinct summary of the state of the art in the field of ownership development. I feel tempted to paste it here:

“Infants begin to show an understanding of ownership relationships between 1.5 and 2 years of age when they first use possessive pronouns like “mine” and “yours” (Hay, 2006; Tomasello, 1998) and identify owners of familiar objects such as their mother’s toothbrush (Fasig, 2000). From two years of age children infer ownership of unfamiliar objects based on first possession, attributing ownership to the person who possessed an object first (Friedman & Neary, 2008). At 2.5 years of age they are able to learn ownership relationships between out of view objects and their owners (Blake & Harris, 2011). These abilities become more refined at three years of age, when children use object history to infer ownership (Friedman, Van de Vondervoort, Defeyter, & Neary, 2013; Gelman, Manczak, & Noles, 2012) and apply ownership rules such as ascribing ownership to a person who grants/denies permission to use an object (Neary, Friedman, & Burnstein, 2009) or who invested effort in making a new object (Kanngiesser, Gjersoe, & Hood, 2010). Yet, not until four years of age do children prioritize verbal ownership statements over physical possession of objects (Blake, Ganea, & Harris, 2012). Taken together, these findings suggest that children’s understanding of ownership relationships manifests at two years of age and becomes more sophisticated during the preschool years.”

The previous paragraph deals with “ownership conditions,” i.e. how children determine who owns what. Then they use a separate paragraph to describe the state of the art concerning “ownership implications,” i.e. children’s understanding of ownership rights.

“Relating owners to their property, however, is only one ability necessary for developing a concept of ownership. Few studies have directly investigated at what age children start to appreciate the normative implications of ownership, i.e., that it is associated with certain rights that are respected and reinforced by a community. By age two children frequently defend their possessions (or possessions they were told were theirs) against take-over attempts by others (Eisenberg-Berg, Haake, & Bartlett, 1981; Hay & Ross, 1982) and begin to show respect for others’ ownership of objects (Ross, 1996), providing some evidence for an early understanding of an owner’s exclusive access to his or her property. In contrast, studies presenting children with third party ownership stories have shown that it is not until age 4–5 that children appreciate different ownership rights (Kim & Kalish, 2009) or differentiate between legitimate (gift giving) and illegitimate (stealing) transfers of ownership (Blake & Harris, 2009). Yet, more recently, Rossano and colleagues (2011) demonstrated that 2- and 3-year olds protested against property rights violations when their own property was at stake, but that only 3-year-olds also interfered when a third party’s ownership rights were violated. This suggests that by age 3 children are already aware of the normative structure of some rights for personal property, i.e., that property rights do not apply only to one’s own possessions but to others’ possessions, too.”

The paper then describes two experiments. In Experiment 1, they have a puppet taking away an object the child has just created out of raw materials provided by the researcher–or, alternatively,  that a third person (an experimenter) has just made, and monitor children’s protests. After registering children’s spontaneous protests (or lack thereof) they explicitly asked children who the object’s owner was. Experiment 2 is similar to experiment one except that the objects at stake are raw materials and not newly made objects.

Conclusions:

“ We found that 2- and 3-year-olds protested when their own objects were at stake, making spontaneous references to ownership when protesting (e.g., “Mine.”). Thus, young children do not only appreciate their ownership rights with respect to personal property items (Rossano et al., 2011), but also with respect to newly made objects. Children’s ownership claims regarding their objects were specific to the investment of effort (Kanngiesser et al., 2010), as children who had only played with unchanged materials displayed very little ownership protest. Overall, our results support the view that by three years of age, children not only can connect owners to property (Blake & Harris, 2011; Fasig, 2000; Friedman & Neary, 2008), but also show appreciation of at least some ownership rights (Rossano et al., 2011). In contrast to other studies, young children in our study intervened little against the puppet’s attempts to keep a third party’s objects.”

Kanngiesser & Hood also conclude that “most 3-year-olds in our study recognized a third party’s ownership of her newly made objects when they were asked direct ownership questions, suggesting that 3-year-olds may have lacked the motivation rather than the competence to protest against violations of a third party’s ownership rights”, so it can be argued that “3-year-olds viewed the investment of effort into creating new objects – but not the mere handling of materials – as sufficient for establishing ownership of previously un-owned materials.”

One might argue, however, that the key factor here is creation (which involves both having an idea about what to make, and actually investing effort in creating an object) and not simply invested labor or effort. (As Levene et al make clear in Levene, M., Starmans, C., & Friedman, O. (2015). Creation in judgments about the establishment of ownership. Journal of Experimental Social Psychology, 60, 103–109.)

Finally, “The most remarkable finding in our studies is that 3-year-olds are capable of attributing ownership to a third party and yet they seldom intervene when the third party’s possessions are at stake. There are two possible explanations. Three-year-olds’ understanding of the social consequences of ownership (such as violations of ownership rights) may lag behind their ability to track ownership relationships. Two-year-olds track ownership relationships (Fasig, 2000; Hay, 2006), but at age 3 children already interfere in ownership conflicts on behalf of a third party (Rossano et al., 2011). Moreover 3-year-olds have been found to regularly intervene in a variety of situations involving violations of conventional and moral norms (Rakoczy et al., 2008; Schmidt, Rakoczy, & Tomasello, 2012; Vaish et al., 2011). Our discrepant findings thus may not reflect different developmental trajectories but rather different task demands. While answering ownership questions only requires the child to point to or to name a person, intervention in ownership violations requires an assessment of the social situation and, importantly, a motivation to act on behalf of a third party.”

Ownership, object history and endowment effect in 2 and 3 year olds – Gelman

Text #13

Gelman, S. a., Manczak, E. M., & Noles, N. S. (2012). The nonobvious basis of ownership: Preschool children trace the history and value of owned objects. Child Development, 83(5), 1732–1747. doi:10.1111/j.1467-8624.2012.01806.x

The paper presents two studies with 2 year-olds, 3 year-olds, and adults. The first study addresses the use of object history to determine ownership, while the second studies the endowment effect. The experimental design is very simple: assign objects (from certain object sets) to individuals, and then ask subjects a) which object belongs to whom, b) which object they like best.

1) Ownership is abstract… or nonobvious.

One a conceptual level, it is interesting that this paper emphasizes the fact that ownership is abstract. I have previously used that word, abstract, to refer to ownership in a recent paper of my own. But, actually, that’s not the word that Gelman et al. prefer to use when speaking of ownership; they describe it as nonobvious rather than abstract. Here’s what they say:

  • Ownership is of interest because it is a cognitive construction, not materially present in the owned object. As Snare (1972, p. 200) aptly stated, ‘‘[A] stolen apple doesn’t look any different from any other apple.’’
  • A mature concept of ownership includes an understanding that proximity, perceptual or functional features, and desirability, although potent factors, cannot by themselves determine who owns what. In other words, ownership is an invisible quality that can be traced by consideration of object history rather than by inspection of the properties of the object.

I don’t know why the talk about “nonobvious” rather than “abstract”. Abstract seems to be the common-sense word to describe invisible, relational features.

2) Object history.

In order to assess who owns what, human agents reconstruct the history of each individual object (“first I found it there, then I gave it to her, then she placed it in that red box… etc.). “Given the centrality of object history, it becomes particularly important to track where an object moves over time.”

“Experiment 1 demonstrates that 3-year-olds, like adults, construe ownership as a nonobvious property that does not reduce to outward perceptual or functional features”. “This doesn’t seem to be the case for 2-year-olds, who in certain experimental situations and with certain sets of objects do not seem to use object history in their ownership judgments.” “The present studies demonstrate that children as young as 3 years of age spontaneously attend to object history to determine ownership.”

3) Endowment effect

The authors claim that they are the first to demonstrate an endowment effect in children 2 and 3 years of age. “The present findings suggest that positive evaluation of and preference for one’s own possessions is a basic cognitive disposition, even before children have experience with conventional economic transactions.”

This is interesting. By the way, why do they say that the disposition to value one’s own stuff is “cognitive”? They call it a “cognitive disposition”. But you can make the case that such a basic way of being of humans and perhaps other species is not appropriately described as “cognitive”. We are dealing with something that is as emotional as it is cognitive. We value and defend what we are and what we have. This phenomenon (the endowment effect) might be linked even with territorial behaviors. I think there are deep existential, cultural and evolutionary motivations in this “will to possess” and to value what one has. The word “cognitive” would suggest a conceptual frame, an innate category, some “cold” rule or feature of our cognitive system. It’s not proved that that’s the best description of what’s going on here.

“Ownership confers special value on objects, across the life span. This finding extends beyond prior work in demonstrating that preference is for the particular object assigned (not just for that type of object).”

4) Endowment effect precedes object history tracking

“The most striking developmental change concerned the comparison between the two experiments. Three-year-olds and adults distinguish ownership from likability, reporting that they owned objects even when they did not like them (e.g., the participant-plain items). In contrast, 2-year-olds show no difference between the ownership task (Experiment 1) and the endowment task (Experiment 2). In other words, 2-year-olds conflate ownership with desirability, thus failing to grasp that a toy they do not like actually belongs to them.

5) Mutual exclusivity

“Participants showed a mutual exclusivity bias concerning ownership, rarely assigning an object to Zippy [a fictional character they introduced in some situations] that had already been assigned to another owner. Mutual exclusivity is a principle that young children adhere to in their word extensions (Markman, 1989; Markman, Wasow, & Hansen, 2003), and it is notable that this same principle applies outside the realm of labeling.”

One might speculate about mutual exclusivity as a common feature of ownership and language. Perhaps this is an innate rule or constraint of our cognitive system, that is applied to different domains as language and ownership? Or perhaps mutual exclusivity as a principle co-evolved with human society and the rules of ownership? There are theories that derive human’s symbolic functioning from social life, and in particular from the institution of ownership. Mutual exclusivity is essential for the institution of ownership: the very meaning of something being mine is that I, not you, control it; if something is mine it’s not yours. In order to claim something as your own, you need to put a mark on the object, or make a gesture, or use some other symbolic means, that might be at the very origin of the semiotic function in general and language in particular.

 

Children think that creative labor justifies ownership transfers (Kanngiesser)

Kanngiesser, P., Gjersoe, N., & Hood, B. M. (2010). The effect of creative labor on property-ownership transfer by preschool children and adults. Psychological Science : A Journal of the American Psychological Society / APS, 21(9), 1236–1241.

Another important study by Kanngiesser.

Let me first paste the abstract:

“We investigated whether preschool children and adults believe that ownership of one person’s property is transferred to a second person following the second person’s investment of creative labor in that property. In our study, an experimenter and a participant borrowed modeling-clay objects from each other to mold into new objects. Participants were more likely to transfer ownership to the second individual after he or she invested creative labor in the object than after any other manipulations (holding the object, making small changes to it). This effect was significantly stronger in preschool children than in adults. Duration of manipulation had no effect on property-ownership transfer. Changes in the object’s identity acted only as a secondary cue for children. We conclude that ownership is transferred after an investment of creative labor and that determining property ownership may be an intuitive process that emerges in early childhood.”

First reflection: even though from our theoretical point of view we like to distinguish between things like “creation”, “discovery” or “transformation through the investment of labor”, maybe these are not too different from each other from the point of view of the child. That is, in all these cases, there is an agent that develops a purposeful and laborious activity on the object that is transformed as a result; and that is transformed into something that is either beautiful, or useful, or has value in some way. So children (and humans in general) understand that value is created through an agent’s activity. (This is Locke’s thesis, and it’s also part of our common sense). Once you think about it in these terms, it makes sense that children don’t pay attention to things like “duration of possession” or minor manipulations of the object; they don’t follow such mechanistic criteria, they look at transformations that make sense.

This paper, therefore, does not belong to the topic of “ownership transfer” but to the topic of “ownership claims”, in my opinion. If you take the duck and make an ashtray, you might say that the ownership of the play dough was transferred. But you can also say that you destroyed the duck and created an ashtray. You are the owner of the object you created (ownership principle).

“When asked to justify their property ownership decisions, 3-year-olds never mentioned creative labor, whereas 4-year-olds justified ownership transfers with explicit reference to creative investment. Moreover, we found that for children, the main component of creative labor was the invested effort, and the secondary component of creative labor was changing an object’s identity.” “We found that this transfer overruled an established bias to assign ownership to the individual who first possessed an object.”

“We found that children transferred ownership more frequently after making small changes to another person’s object than after possessing the same object, a result suggesting that children’s ownership judgments may even be finely calibrated to the amount of effort invested in an object.”

Creative labor has an effect on ownership judgments in adults, but the effect is less pronounced in adults than in children.

Esther Perel and ownership

Leave a reply

Text #8

I’ve recently finished reading Esther Perel’s Mating in intimacy (Perel, 2006). What a great book. Highly recommended, not only to couples’ therapists or even psychotherapists. All psychologists should read it. Her view of relationships and particularly of sexuality in the contemporary world is really revolutionary. The only thing I don’t completely buy are her interventions in couples’ therapy: some of them sound as too theoretical, and I don’t think such verbal and general explanations can make people change. Usually, they just become rationalizations.

What does her book have to do with the stuff I discuss in this blog? Not much. But let me emphasize that I don’t consider ownership as only a social phenomenon that children need to learn about. In other words, I don’t consider ownership just as a topic within social cognition. (For example: how children develop heuristics to understand what belongs to whom). Ownership is not outside the child; ownership is not a source of input for children’s cognitive system. Not only, at least. The socio-cognitive approach reveals an important aspect of ownership, but not the most fundamental.

I’m rather interested in the experiential, existential side of it: why is it that humans need to possess stuff and to be acknowledged by others as legitimate owners; how do individuals clash with each other when competing for possession; how they become attached to their property. This is the kind of questions Rousseau used to ask, and that Rochat (Rochat, 2014) also tackles in his recent book on possession.

And Perel’s book does teach us something about it: that people can have a satisfactory sexual life only when they own it: when they own their bodies, their erotic imagination, their capacity to love.
