Our memories can differ in quality from one event to the next and emotion is one important explanatory factor. Still, the manner in which emotion impacts episodic memory is complex: Whereas emotion enhances some aspects of an episodic memory—particularly the central aspects—it dampens memory for non-central information, such as spatial context. Extending this work, we examined the effect of emotion on another important element of an event, its temporal context. We tested the hypothesis that emotion would impair memory for “when” an event occurred. Human participants (N = 116) watched a series of short videos, wherein either a negative or neutral image was superimposed, followed by a test. In accordance with prior work, emotion enhanced and impaired memory, respectively, for “what” and “where”. Unexpectedly, emotion was associated with enhanced accuracy for “when.” By examining multiple features of episodic memory, we provide a holistic characterization of the myriad effects of emotion.
