Does sleep change the emotional bias in memory in older adults?

ABSTRACT: Sleep supports the consolidation of emotional memories. Young adults exhibit a bias towards consolidation of negative memories during sleep while older adults exhibit a bias towards consolidation of positive memories, which parallels known biases in emotional memory encoding. Yet it is unclear whether biases found after sleep are carried over from biases in encoding or if sleep amplifies or changes the emotional memory biases as prior studies did not include a measure of memory before the sleep/wake interval. The present study assessed emotional memory before and after intervals of sleep and wake to determine whether sleep biases the selectivity of emotional memory. Healthy young (N = 49) and older adults (N = 50) completed both a positive and negative emotional memory task. Emotional imag
