Abstract
Adaptive memory retains information that would increase survival chances and reproductive success, resulting in the survival processing effect. Less is known about whether the reliability of the information interacts with the survival processing effect. From an adaptive point, information from reliable sources should lead to better encoding of information, particularly in a survival context. In Turkish, specific linguistic components called evidentiality markers encode whether the information presented is firsthand (direct) or not (indirect), providing insight into source reliability. In two experiments, we examined the effect of evidentiality markers on recall across survival and nonsurvival (moving) contexts, predicting that the survival processing effect would be stronger for information marked with evidentiality markers indicating direct information. Results of both experiments yielded a robust survival processing effect, as the sentences processed for their relevance to survival were better remembered than those processed for their relevance to nonsurvival events. Yet the marker type did not affect retention, regardless of being tested as a between- or within-subject factor. Specifically, the survival processing effect persisted even with evidentiality markers indicating indirect information, which suggests that the processing of survival-related information may be privileged even if potentially unreliable. We discuss these results in the context of recent studies of the interaction of language with memory.
