Autobiographical Memory for Emotional Events: A Test of the ‘Warning Signal’ Hypothesis
According to the warning signal hypothesis, memory may be enhanced for peripheral details occurring immediately before a traumatic experience to signal potential danger if encountered again. This idea contrasts with research demonstrating a temporal memory trade-off, where central details of distressing events are prioritised over peripheral information occurring immediately before or after. This study aimed to experimentally test the warning signal hypothesis, by comparing episodic details from neutral, positive and negative/trauma-related autobiographical memories. Participants (N = 175) wrote short narratives to facilitate recall of each event and the moments leading up to it, then rated their memories on vividness and level of detail. Memories of moments preceding emotional experiences were recalled with greater vividness and detail compared to neutral experiences. Contrary to the warning signal hypothesis, the prioritisation of preceding stimuli does not appear specific to traumatic experiences and may instead reflect a general mechanism prioritising temporally proximal and emotionally significant information.
期刊介绍：
Applied Cognitive Psychology seeks to publish the best papers dealing with psychological analyses of memory, learning, thinking, problem solving, language, and consciousness as they occur in the real world. Applied Cognitive Psychology will publish papers on a wide variety of issues and from diverse theoretical perspectives. The journal focuses on studies of human performance and basic cognitive skills in everyday environments including, but not restricted to, studies of eyewitness memory, autobiographical memory, spatial cognition, skill training, expertise and skilled behaviour. Articles will normally combine realistic investigations of real world events with appropriate theoretical analyses and proper appraisal of practical implications.
