Abstract

AIM: Feelings of defeat and deficits in autobiographical memory are thought to be central to the formation of suicidal thoughts and behaviours. However, no work has established the role of defeat, specifically, in directly leading to memory problems. This study sought to assess whether a defeating event and associated defeated mood impaired memory for a story. METHOD: Participants were from a student population. Those in the experimental condition (n=37) experienced an event which was designed to induce defeat prior to both the encoding and verbal retrieval of a story. Participants in control condition (n=37) experienced no such defeating event. Visual analogue scales of five mood states were taken at baseline, prior to encoding and prior to retrieval. RESULTS: Participants in the experimental condition reported increased feelings of defeat following baseline, and recalled fewer story units relative to the control condition. DISCUSSION: These results show that appraising an event as defeating increased subsequent defeated mood and led to impaired episodic memory, independently of low mood in general, thus suggesting a causal role of a specific negative mood state on impaired memory. Implications for clinical research are discussed.
