ABSTRACT Human memory likely evolved to serve adaptive functions, that is, to help maximise our chances of survival and reproduction. One demonstration of such adaptiveness is the increased retention of information processed in survival contexts, the so-called Survival Processing Effect (SPE). This study examined this effect in a native (L1) and in a second language (L2). This comparison is relevant to explore if emotionality is involved in the SPE, as emotional activation seems to be larger in L1 than in L2. Following the original survival processing procedure, participants rated the relevance of information to the survival and moving scenarios and performed a recognition (Experiment 1) or a free recall (Experiment 2) task in L1 or L2. In both experiments, the SPE was replicated in L1 but not in L2. The absence of the effect when emotional activation is less likely suggests that emotionality might play a role in the survival processing effect; nevertheless, additional studies are needed to further investigate this hypothesis.
