情绪体验比中性体验更容易记忆，但情绪是否能改善对体验各个方面的记忆仍不清楚。一些研究人员认为，情绪对记忆的影响对于项目和源信息是不同的，而另一些人则认为情绪对两者的影响是相似的。我们研究了年轻人和老年人对情感和中性材料的项目记忆和源记忆。对情绪性项目的记忆上级优于对中性项目的记忆，而在源记忆上没有差异。总的来说，老年人的项目记忆和源记忆比年轻人差，但情绪似乎对两个年龄组都有类似的影响。虽然情感内容比中性内容更容易记住，但这种好处并不适用于源记忆。然而，改变源的情感（即，实验3中的声音改善了对声音来源的记忆，这种效果在年轻人中比在老年人中更大。语调对老年人的项目记忆没有影响，但这种影响在年轻人中是可变的，可能取决于语调在多大程度上缓和了对内容的解释。
Emotional experiences are easier to remember than neutral ones, but whether memory for all aspects of an experience is improved by emotion remains unclear. Some researchers have argued that the influence of emotion on memory is different for item than for source information, whereas others have argued that emotion affects both similarly Also, whether item and source memory are affected by emotion in older people in the same way as in young people is currently unclear. We examined item and source memory for emotional and neutral materials in young and older adults. Memory for emotional items was superior to memory for neutral items, whereas there was no difference in source memory. Overall, item and source memory were poorer in older people than in young people, but emotion seemed to have a similar effect on both age groups. Although emotional content was remembered better than neutral content, this benefit did not apply to source memory. However, varying the emotionality of the source (i.e., the voice in Experiment 3) improved memory for the source, and this effect was greater in young than in older people. Tone of voice had no effect on item memory in older people, but the effect was variable in the young and may depend on the extent to which the tone of voice moderates the interpretation of the content.
