Selective effects of emotion on memory: How emotion enhances and impairs memory
Over the last two decades, there has been an increasing recognition that emotion plays important roles in students’ learning. However, previous research has suggested a complex picture: negative emotion often impairs students’ learning but sometimes enhances students’ learning.
According to recent theoretical accounts, when encountering something emotional, momentary increases in arousal should amplify neural gain; such that stronger inputs should be prioritized more under emotional arousal, while weaker signals should not benefit from arousal.
During the presentation, I will present findings from experiments where we tested this prediction in memory and perception. We found that emotional arousal enhances memory for other information when it is goal-relevant and therefore has strong inputs, whereas emotional arousal impairs memory for other information when it is goal-irrelevant and therefore has weaker inputs. We also found that emotional arousal selectively enhances perception of salient signals over non-salient signals. These results suggest that momentary increases in arousal due to emotional events have enhancing effects only for strong and prioritized representations.
