Emotional arousal enhances memory at different phases of processing, including encoding, memory retention, and retrieval. Here, the cognitive and neural mechanisms underlying the modulation of memory retention (chapter 1) and retrieval (chapter 2 & 3) by emotion are examined. Chapter 1 includes a series of behavioral studies aimed at disentangling the effects of emotion on retention from those on attentional processes during encoding. The results indicate that arousal supports slower forgetting even when the difference in attentional resources allocated to stimuli are minimized, implying that arousal can boost memory consolidation independently of any modulation of attention during encoding. Modulation of retrieval mechanisms, related to the subjective sense of remembering, are addressed in chapters 2 & 3. In Chapter 2 we measure brain activity associated with the feeling of remembering emotional and neutral photos. A second brain imaging study, presented in Chapter 3, extends this investigation to more complex, real-life autobiolographical emotional events. The findings of both studies suggest a dissociation between the neural systems underlying retrieval of emotional events and those underlying retrieval of neutral events. We find that while the amygdala is preferentially involved in the retrieval of emotional stimuli that are remembered with great detail and vividness, the parahippocampal cortex seems more involved in the retrieval of neutral stimuli. This pattern of activation may underlie the exaggerated feeling of remembering previously reported for emotional events.
