If I told you everyone picked that (non-affordant) tool, would you? Children attend to conventional language when imitating and transmitting tool use.

This study explored how conventional versus instrumental language influenced children's imitation and transmission of non-affordant tool use. Rather than examining children's imitation of unnecessary actions that do not impede goal completion, we examined children's conformity with a modeled behavior that may result in sacrificing goal completion. Children (N = 96 4- to 6-year-olds) were presented with either a conventional or instrumental description of a model's actions before watching the model choose a non-affordant tool. Children who heard conventional language imitated and transmitted the model's non-affordant tool choice at significantly higher rates than when they heard instrumental language. The results have implications for children, parents, and teachers regarding the extent to which children will conform with what "we" are "supposed" to do.

Cultural differences in the imitation and transmission of inefficient actions.

Across two studies, we explored cultural differences in children's imitation and transmission of inefficient actions. Chinese American and Caucasian American preschoolers (N=115) viewed either one or three models using two inefficient tools to perform two different tasks. In the video, when the model(s) performed the task, only the inefficient tool was available; thus, their choice to use that tool could be considered rational. Next, children were invited to complete the task with either the inefficient tool or an efficient alternative. Whereas the two cultural groups imitated a single model at similar rates, Chinese American children imitated significantly more than Caucasian American children after viewing a consensus. Similar results were found when exploring differences in information transmission. The Chinese American children were significantly more likely than their Caucasian American peers to instruct using an inefficient tool when they had initially viewed a consensus demonstrate it. We discuss these findings with respect to differences in children's use of social versus task-specific cues for learning and teaching.

The role of consensus and culture in children's imitation of inefficient actions.

A significant body of work has demonstrated children's imitative abilities when learning novel actions. Although some research has examined the role of cultural background in children's imitation of inefficient actions, to our knowledge no research has explored how culture and conformity interact when engaging in imitation. In Study 1, 87 Caucasian American and Chinese American preschoolers were presented with either one model or three models performing an inefficient action. Whereas there were no cultural differences in imitation in the Single Model condition, Chinese Americans were significantly more likely to copy the model's preference for an inefficient tool in the Consensus condition. Children's tool choice was associated with their justification for their choice as well as their memory for the model's action. Study 2 explored the impact of immigration status on the cultural differences in children's tool choice by including 16 first-generation Caucasian American children. When comparing the findings with the rates from Study 1, both groups of Caucasian American preschoolers imitated at rates significantly lower than the Chinese American preschoolers. We suggest that the tool choices of Caucasian American children relate to a tendency to engage in a perceptually driven mode of learning, whereas the choices of the Chinese American children reflect a greater likelihood to use a socially driven mode.
