Modulation of Maintenance and Processing in Working Memory by Negative Emotions
SymposiumTalk-01
Presented by: Gaën Plancher
Previous research has shown that working memory processes are affected by emotion. However, it is not clear if both components – maintenance and processing of information – are modulated by emotion. Some theoretical models assume that working memory is a unitary system, resulting in a perfect trade-off between maintenance and processing. If this is true, we should observe that processing emotional information affects memory performance and that maintaining emotional stimuli affects the processing of neutral information. Since emotion is intimately related to attention, we focused on attentional maintenance. In several experiments, using complex span tasks, we observed lower recall when negative stimuli were processed compared to neutral ones and longer processing times when series of negative stimuli were maintained. Overall, our results showed that emotion impacts both processing and attentional maintenance in working memory. This is consistent with models of working memory suggesting an attentional trade-off between maintenance and processing.
