Warneken: Young children share the spoils after collaboration

Warneken, F., Lohse, K., Melis, A. P., & Tomasello, M. (2011). Young children share the spoils after collaboration. Psychological Science, 22(2), 267–73.

Interesting paper.

1) The authors postulate that the relationship between joint collaboration and sharing is crucial for understanding the origins of equality, both in ontogeny and phylogeny. Therefore, they investigate how children actively divide rewards after working for them in a collaborative problem-solving task.

Most studies on sharing involve windfall situations, in which resources are given to the children by a third party, with no work or effort involved. Moreover, many studies use a forced-choice paradigm with predefined allocation options, which does not allow for an assessment of how children themselves would actively negotiate over how to distribute resources with another person.

In contrast, Warneken et al.’s research is guided by the notion that people often have to work toward obtaining resources, and that they distribute those resources actively, rather than choosing individually between predefined options. Previous studies, they say, have not shown how children share resources in situations that might be the cradle of equality: actual joint collaborative activities with a social partner.

2) The experiment closely resembles sharing experiments with chimpanzees and other non-human primates. Warneken et al test children in dyads. Children have to perform a task together: they have to pull from both ends of a rope at the same time in order to bring a box close to them. In this way, they are able to get a reward (such as stickers or candy that have been placed in the box). In one condition, the box has two holes far apart, so that each child can get her reward without interference from the other participant. In a second (“clumped”) condition, the box has only one hole, and therefore only one child can access the rewards at a time.

3) Warneken et al. found that neither the reward type nor the opportunity to monopolize rewards in the clumped condition interfered with the children’s collaboration. 3 year-olds collaborate successfully in situations in which resources can be monopolized. The collaborative abilities of young children, compared with those of chimpanzees, are not constrained to the same extent by a tendency to monopolize resources.

Children predominately produced equal shares. They shared rewards equally most of the time, even when rewards could be monopolized more easily (clumped condition). At an age when children are just beginning to skillfully collaborate with peers, they already engage in sharing behavior that results in equitable outcomes.

4) What does it all mean? Competition over resources, the authors claim, is mitigated in human children (when compared with chimpanzees and other primates) by an emerging sense of equal sharing of the spoils, which enables successful collaboration even early in ontogeny. Thus, the authors claim that this study supports a Tomasello-like evolutionary hypothesis, according to which the emergence of cooperation is due not only to cognitive and behavioral skills, but also to a reduction in competition over resources. Competition over resources is mitigated in human children by an emerging sense of equal sharing of the spoils, which enables successful collaboration even early in ontogeny.

5) According to this study, children are capable of equitable distributions a very early age. Although many studies place the origins of equality at around 5, 6 or even 7 years of age, it all depends on how the concrete distribution problem is presented to the children. Warneken et al. present children with a collaborative, non-competitive situation. In addition, in this study the peer is present; the dyad works together in a problem solving activity (compare this with economic games that are played by a single present individual and an absent, anonymous, “invisible”). Even more, some of the dyads comprise children who know each other well, since they attend the same day-care center (they are not one-shot interactions, as in most economic games). All this seems to help even 3 year-olds to produce equitable outcomes early in development. The authors reach the conclusion that, perhaps, children learn to acknowledge each other’s right to gain equal resources in situations in which they collaborate to produce a mutually beneficial outcome that one person acting alone would not be able to achieve (this result is not proven by the experiment, in my opinion).

Possession as the origin of property

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 value ideas over labor

Text #15

Li, V., Shaw, A., & Olson, K. R. (2013). Ideas versus labor : What do children value in artistic creation ? COGNITION, 127(1), 38–45. doi:10.1016/j.cognition.2012.11.001

The procedure is simple: have an adult direct a child making a work of art (so that the adult is contributing the guiding ideas while the child is contributing “brute” labor). Then, reverse the roles: have the child supply the guiding idea while the adult follows directions and executes the work of art. Finally, have the child chose which final product she prefers to take home with her: the one that incorporated her effort or the one that reflects her idea?

In a second experiment, the researchers used a similar situation but now they tricked the subjects so that children believed that the drawing contained their ideas when it actually contained the adult’s idea (and vice versa, they believed that the drawing which they had actually created while being directed by an adult was the one that incorporated their ideas).

In a third experiment, they used a third person narrative to lay out a comparison between someone who contributes labor and someone who contributes ideas to the creation of an object. Who should keep the resulting product?

These studies demonstrated that by 6 years old, children value ideas over physical labor. Six year olds systematically chose pictures that contained their own ideas over pictures that contained their labor, even when they were merely tricked into believing that they had come up with the idea for a picture that they had not. Further, 6 year olds demonstrated a general appreciation of ideas – they not only valued their own ideas (Studies 1 and 2), but also privileged idea creators over laborers in a property dispute (Study 3). In contrast, 4 year olds appear to have preferred pictures that contained their specific idiosyncratic preferences. Four year olds preferred pictures containing their ideas, but also their idiosyncratic preferences in Study 1 and pictures they believed contained their labor but also their idiosyncratic preferences in Study 2. Further supporting this possibility, in Study 3 where idiosyncratic preferences could not play a role in selection, 4 year olds showed no bias for either a third-party idea creator or laborer. Six year olds, by way of contrast, sided with the idea creators in third-party case, even when they personally had no connection to the idea.

The age effect in these studies may exist because 6, but not 4 year olds, understand that ideas are valuable and can thus be owned.

In conclusion, the tendency to value ideas is present in childhood and may emerge between 4 and 6 years old. 6 year olds value ideas over labor even when making third-party judgments, favoring those who only contributed ideas as more deserving of a picture over those who only contributed labor.

Children think that creative labor justifies ownership transfers (Kanngiesser)

Text #10

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 though 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 this terms, it makes sense that children don’ 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.
