A dual-process perspective on over-imitation

Publication date: March 2020Source: Developmental Review, Volume 55Author(s): Hanna Schleihauf, Stefanie HoehlAbstractChildren and adults tend to imitate actions that are causally irrelevant to accomplishing a goal; they “over-imitate.” It has been discussed that humans over-imitate either because of erroneous causal reasoning, meaning that they do not recognize demonstrated actions as being irrelevant, or because of social motivation, for example, because they want to follow a norm or affiliate with the demonstrator. Recent findings give reason to believe that neither of these accounts alone is sufficient to explain this phenomenon. Here, we introduce a dual-process framework that integrates existing explanatory accounts for over-imitation and indicates when which of these accounts is applicable. According to this integrative framework, over-imitation can be based on different underlying motivations. We introduce two distinct processes: First, blanket copying, which is based on type 1 processing that is less cognitively demanding. When children perform blanket copying, they imitate irrelevant actions without questioning their necessity. Second, deliberate considerations whether or not to copy, based on type 2 processing that requires more cognitive resources. When children are aware that some of the demonstrated actions have no functional purpose, they can deliberately consider whether or not to copy. Then, it depends on the children’s goals in a given situation whethe...
