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.
