Survival processing in times of stress

Recent studies have found that processing information according to an evolutionary relevant (i.e., survival) scenario improves its subsequent memorability, potentially as a result of fitness advantages gained in the ancestral past. So far, research has not revealed much about any proximate mechanisms that might underlie this so-called survival processing advantage in memory. Intriguingly, research has shown that the memorability of stressful situations is enhanced via the release of stress hormones acting on brain regions involved in memory. Since survival situations habitually involve some degree of stress, in the present study, we investigated whether stress serves as a proximate mechanism to promote survival processing. Participants rated words for their relevance to either a survival or a neutral (moving) scenario after they had been exposed to a psychosocial stressor or a no-stress control condition. Surprise retention tests immediately following the rating task revealed that survival processing and acute stress independently boosted memory performance. These results therefore suggest that stress does not serve as a proximate mechanism of the survival processing advantage in memory

Recovered memories of childhood sexual abuse: Current findings and their legal implications

Recent research on recovered memories of childhood sexual abuse has shown that there are at least two types of recovered memory experiences: those that are gradually recovered within the context of suggestive therapy and those that are spontaneously recovered, without extensive prompting or explicit attempts to reconstruct the past. By focusing on well-known imperfections of human memory, we were able to find differing origins for these recovered memory experiences, with people recovering memories through suggestive therapy being more prone to forming false memories, and with people reporting spontaneously recovered memories being more prone to forgetting prior incidences of remembering. Moreover, the two types of recovered memory reports are associated with differences in corroborative evidence, suggesting that memories recovered spontaneously, outside of suggestive therapy, are more likely to correspond to genuine abuse events. In this paper, we summarize recent research on recovered memories and we argue that these scientific findings should be applied in the justice system, but also in clinical practice
