Prior research suggests that older adults judge their learning as well as young adults, but given age-related differences in the processing of emotional materials, older adults may show deficits in their judgment accuracy when they study emotionally charged words. In 2 experiments, we evaluated this possibility by having young and older adults study negative, positive, and neutral words. They made a judgment of learning (JOL) after studying each word and then later had a free recall test. In Experiment 1, young and older adults' JOLs were sensitive to negative words (higher JOLs for negative than neutral words). By contrast, whereas young adults' JOLs were sensitive to positive emotion (higher for positive than neutral words), older adults' JOLs were insensitive. In Experiment 2, we replicated this age-related deficit in sensitivity to positive emotion, as well as evaluated possible explanations for it. As important, in both experiments, JOLs were plotted as a function of input serial position, and the shape of these curves were not influenced by emotional valence or age group. Taken together, these results indicate that healthy aging largely leaves judgments of learning intact for negatively charged words.
先前的研究表明,老年人和年轻人一样能够评估自己的学习情况,但由于情绪材料处理方面存在与年龄相关的差异,因此老年人在学习带有情绪色彩的单词时,其判断准确性可能存在缺陷。在 2 项实验中,我们通过让年轻和年长的成年人学习负面、正面和中性词汇来评估这种可能性。他们在学习每个单词后对学习判断(JOL)进行了判断,然后进行了自由回忆测试。在实验 1 中,年轻和年长成年人的 JOL 对负面词汇敏感(负面词汇的 JOL 高于中性词汇)。相比之下,尽管年轻成年人的 JOL 对积极情绪敏感(积极词汇的 JOL 高于中性词汇),但年长成年人的 JOL 不敏感。在实验 2 中,我们复制了这种对积极情绪敏感性的年龄相关缺陷,并对其可能的解释进行了评估。同样重要的是,在这两项实验中,JOL 都作为输入连续位置的函数进行绘制,而这些曲线的形状不受情绪效价或年龄组的影响。总之,这些结果表明,健康的衰老在很大程度上使对带负电单词的学习判断保持完整。
