Adaptative memory and animacy effect

subject

description

According to the adaptive memory view, human memory was shaped in the distant past to remember fitness relevant information (e.g., finding food, protecting ourselves from predators). An increasing number of studies favor this view, by showing that information related to to survival is memorized better than information not related to survival (Nairne, Thompson, & Pandeirada, 2007). Recently, a new type of findings further supports this functional approach of memory: animacy effects, that is to say the observation that animates (living things able of independent movements; e.g., baby, grasshopper) are remembered better than inanimates (non-living things e.g., teakettle, rope). One account of this memory effect has been that animates are of greater importance for survival and/or reproduction. In effect, knowing how to interact with animates was crucial for the survival of our ancestors, and thus, for the evolution of our species. In this work, our main purposes were to identify some proximate mechanisms underpinning animacy effects in episodic memory as well as the contexts in which these effects are observed. Taken overall, our findings accord with the claim that animacy effects in memory are: (1) linked to recollection (conscious recall of contextual details); (2) independent of cognitive resources; (3) partially underpinned by mental imagery and (4) to some extent modulated by encoding context.
