Young and older participants produced oral picture descriptions that were analyzed to determine the impact of negative emotional content on spoken language production. An interaction was found for speech disfluencies: young adults' disfluencies did not vary, whereas older adults' disfluencies increased, for negative compared to neutral pictures. Young adults adopted a faster speech rate while describing negative compared to neutral pictures, but older adults did not. Reference errors were uncommon for both age groups, but occurred more during descriptions of negative than neutral pictures. Our findings indicate that negative content can be differentially disruptive to older adults' spoken language production, and add to the literature on aging, emotion, and cognition by exploring effects within the domain of language production.
年轻和年长的参与者进行了口头图片描述，分析结果确定了负面情绪内容对口语产生的影响。在言语不流畅方面发现了一种相互作用：与中性图片相比，年轻人的不流畅性没有变化，而老年人的不流畅性增加了。与中性图片相比，年轻人在描述负面图片时会采用更快的语速，但老年人则不会。对于两个年龄组来说，参考错误都不常见，但在描述负面图片时比中性图片更常见。我们的发现表明，负面内容可能会对老年人的口语产生不同的干扰，并通过探索语言产生领域内的影响，为衰老、情感和认知的文献增添了新内容。
