The Influence of Instructional Constraints and Cognitive Control on the Positivity Bias and the Positivity Effect in Autobiographical Memory.

The positivity effect and the positivity bias were examined in voluntary and involuntary autobiographical memories in a sample of younger (n = 69, Mage = 23.2) and older adults (n = 57, Mage = 67.72). The positivity effect has been shown to be sensitive to instructional constraints and cognitive resources. Instructions were manipulated in the voluntary autobiographical memory condition such that participants were instructed to retrieve memories with different levels of constraints. Participants also completed two measures of cognitive control and an assessment of future time perspective. There was no evidence of the positivity effect or positivity bias once depressive symptoms were included as a covariate in the analyses, nor did cognitive control influence memory valence. Future time perspective did not mediate the relationship between age and memory valence. These results suggest that additional research should focus on potential variables that may influence the positivity effect and bias within autobiographical memories.

COVID-19 Pandemic-Related Stress and Subjective Well-Being Across Age: The Mediating Role of Social Resources.

Stress associated with the COVID-19 pandemic and the measures implemented to prevent its spread dramatically shifted our social networks, interactions, and contexts, all of which influence the assessment of one's subjective well-being (SWB). Drawing on data collected from 1,318 adults between April and May 2020, we used structural equation modeling to analyze the relationship between pandemic-related stress and SWB (life satisfaction, positive affect, negative affect), and examined how these relationships vary across age. Pandemic-related stress was associated with lower life satisfaction and higher negative affect. However, no evidence of age moderation emerged. Subsequent analysis examined different aspects of social resources as potential mediating variables. Loneliness fully mediated the relationship between stress and life satisfaction, while social support demonstrated evidence of partial mediation. Further, loneliness and social support partially mediated the relationship between stress and negative affect. Findings suggest that pandemic-related stress impacts SWB, and social resources help explain these impacts.
