摘要
When compared to younger adults, older adults tend to favor positive over negative information in attention and memory. This is known as the positivity effect. Although this is a robust phenomenon, there is still debate about how it relates to individual differences in cognitive capabilities and future time perspective (FTP). To address this, we investigated how measures of fluid cognitive capabilities and FTP related to positivity effects within the domains of episodic memory, visual attention, and autobiographical memory. Cognitive capabilities were assessed using the National Institute of Health Toolbox Cognition battery, and included assessments of executive function, working memory, episodic memory, and processing speed. FTP was assessed via the Carstensen and Lang (1996) scale. Within our final sample (N = 196), we replicated positivity effects in all three task domains, which were all driven by age differences in how people responded to negative (but not positive) information. However, there was limited evidence that the magnitude of these age-related reductions in negativity varied as a function of individual differences in older adults' cognitive capabilities or FTP. Furthermore, when FTP did emerge as a predictor, the pattern was not in line with expectations based upon socioemotional selectivity theory. Thus, the positivity effect may be less reliant on cognitive capabilities and self-reported FTP than is often assumed. Given that there was also very little consistency in the extent to which participants displayed positivity effects across the task domains, these results also raise the possibility that there may be multiple mechanisms underlying positivity effects.
