Subjective age, how old people feel compared to their chronological age, is a central indicator of age identity and highly predictive for developmental outcomes. While mostly used as a trait-like concept in previous research, recent studies employing experimental designs and daily assessments suggest that subjective age can vary after experimental manipulations or between days. However, less is known about whether subjective age varies over even shorter time frames such as within moments on a given day, how such short-term variability differs by age and its association with trait subjective age. We examined these questions with data obtained from 123 young-old (Mage = 67.19 years) and 47 old-old adults (Mage = 86.59 years) who reported their momentary subjective age six times a day over 7 consecutive days as they were going about their everyday lives. Participants felt younger on a large majority of occasions, and 25% of the total variability in subjective age could be attributed to within-person variation. Within-person variability in subjective age amounted to an average of about 3 years from one moment to the next and did not differ between age groups. However, those with younger trait subjective ages exhibited larger moment-to-moment variation. Our findings extend the literature on subjective age by showing that how old people feel can vary on a momentary basis and that state and trait components of subjective age are related. Further research should investigate the contextual predictors of variability in subjective age and the links between trait and state concepts and developmental outcomes.

“今天早上我很老。” 主观年龄的短期变化和特质主观年龄的作用：来自ILSE / EMIL生态瞬时评估数据的证据。

主观年龄，即老年人与他们的年龄相比，是年龄认同的重要指标，对发展结果具有高度预测性。尽管在以前的研究中大多用作类似特质的概念，但最近采用实验设计和日常评估的研究表明，主观年龄在实验操作后或几天之间可能会有所不同。但是，对于主观年龄是否在更短的时间范围内（例如在给定日期的瞬间内）变化，这种短期可变性如何随年龄以及与主观年龄的关联性而知之甚少。我们使用从123位年轻的老年人（法师= 67.19岁）和47位年龄较大的成年人（法师= 86岁）中获得的数据研究了这些问题。59岁），他们在日常生活中连续7天每天六次报告自己的主观年龄。参与者在大多数情况下都感到年轻，主观年龄的总变异中有25％归因于人际变异。人与人之间主观年龄的变异性从一刻到下一刻平均约为3年，并且各年龄组之间没有差异。然而，那些具有较年轻特征主观年龄的人表现出更大的瞬间变化。我们的发现扩展了关于主观年龄的文献，显示了老年人的感觉会随时间变化，并且主观年龄的状态和特质成分是相关的。进一步的研究应调查主观年龄变异的情境预测因素，以及特质和状态概念与发展成果之间的联系。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。
