Daily affect across adulthood and into old age: Recent advances from ambulatory research.

Ambulatory research - such as daily-diary or experience sampling studies - captures experiences as they naturally occur in people's daily lives. It shows that older adults' daily affective experiences, on average, are more positive and more stable, compared to younger age groups. Recent advances in ambulatory research contribute a more refined understanding beyond the valence dimension, demonstrating that the arousal of affective experiences matters as well, and that discrete emotions, such as sadness, may be differently prevalent and adaptive in different phases of adulthood. Another recent contribution is evidence that cross-sectional adult age differences in daily affect may not map onto within-person change over time. While longitudinal improvement in daily affect is observed across young and into early middle adulthood, stability and decline in affective well-being are typical throughout late middle and older adulthood, respectively. Likewise, empirical support for the claim that emotion regulation is a prime reason for age differences in daily affect remains mixed. Older as compared to younger adults are indeed more motivated to feel better, and more confident that their affect-regulation is successful. However, there is no consistent support that older adults' daily affect-regulation strategies, effectiveness, or flexibility differ from younger age groups.
