To resolve discrepancies between studies on the effects of emotional content on working memory, and to examine changes with age, this study examined the effects of emotional content on working memory and subsequent long-term memory for targets and distracters. Thirty-six younger (ages 18-29) and 36 older adults (ages 65-87) participated in a working memory task in which they viewed two target words intermixed with two distracters followed by a probe word, and responded to whether the probe was a target word. The emotional content (valence and arousal) of targets and distracters was manipulated. Subsequent long-term memory was tested with a free recall task. Results indicated that emotional content of targets facilitated working adults experiencing disruption from positive and neutral distracters, and older adults experiencing interference from negative distracters. Emotional effects in long-term memory were only seen for younger adults.
