Imitative flexibility and the development of cultural learning.

Two studies test the hypothesis that imitative fidelity is influenced by cues to interpret behavior as instrumental versus conventional. Study 1 (N=57, 4-5-yr-olds) manipulated non-verbal cues (start- and end-states of action sequences) and Study 2 (N=211, 4-6-yr-olds) manipulated verbal cues to examine the effects of information about instrumental versus conventional goals on imitative fidelity. Imitative fidelity was highest (Studies 1 and 2), innovation was lowest (Study 1), and difference detection was more accurate (Study 2) when cued with information about conventional rather than instrumental behavior. The results provide novel insight into the kinds of information children use to adjudicate between instrumental and conventional behavior.
