Does optimal recall performance in the adaptive memory paradigm require the encoding context to encourage thoughts about the environment of evolutionary adaptation?

This study examined whether encoding conditions that encourage thoughts about the environment of evolutionary adaptation (EEA) are necessary to produce optimal recall in the adaptive memory paradigm. Participants were asked to judge a list of words for their relevance to personal survival under two survival-based scenarios. In one condition, the EEA-relevant context was specified (i.e., you are trying to survive on the savannah/grasslands). In the other condition, no context was specified (i.e., you are simply trying to stay alive). The two tasks produced virtually identical recall despite participants in the former condition reporting significantly more EEA context-relevant thoughts (i.e., the savannah) than did participants in the latter condition (who reported virtually no EEA-related thoughts). The findings are discussed in terms of (1) survival as a target of natural selection and (2) the role of evolutionary theory in understanding memory in modern humans.
