Cognition and equilibrium regulation in development and aging

Abstract

Purpose: Changes in emotion-cognition relationships in later life comprise a pattern of both vulnerabilities and strengths. To integrate this pattern of diversity, I propose a neo-Piagetian extension of the concepts of equilibrium and disequilibrium processes to the relationship beyond cognition to encompass emotional activation and arousal, and beyond youth to the full life span. Content: Beginning with a simple, Cannon-type equilibrium based on the response to increasing deviation from ideal end states of correcting through tension reduction, a more complex model is outlined that additionally uses tension amplification aimed at enlargement of the range over which stability is maintained, i.e., permits processes of developmental progression. Parallel to cognitive development, emotional development is described as the emergence of more complex cognitive-affective structures out of original automatic, biologically based ones. In that process, tension thresholds are raised, and the functional range over which equilibrium can be maintained is widened, as higher-order representations become part of the regulatory network. These progressive movements provide well automated emotion regulation whose effectiveness increases well into middle and late life. Conclusions: In contrast to development, aging is ultimately characterized by a lowering of tension thresholds similar to developmental regression. However, as in the purely intellectual realm, that process is offset by the previous automatization and crystallization of cognitive-affective schemas becomes evident only as a result of increasing constraints on fluid capacities, as in advancing age and/or high load of cognitive effort and/or emotional activation.

Assessment of adult age differences in task engagement: The utility of systolic blood pressure

“…Another interesting finding was that the high level of effort expended by older adults following the difficult task also appeared to have a disruptive effect on performance in the second task. This result appears consistent with theoretical perspectives arguing that declines in cognitive resources in later life result in high levels of arousal being more detrimental to older than to younger adults’ performance (e.g., Labouvie-Vief, 2009). …”

Relative Effectiveness of Reappraisal and Distraction in Regulating Emotion in Late-Life Depression

“…Older adults are hypothesized to benefit from overlearned regulation strategies that rely on crystallized abilities rather than flexible processing (36). While reappraisal requires some cognitive flexibility in re-interpreting a specific stressor, distraction can be implemented regardless of the content of a negative thought or stimulus.…”

Decision‐making heuristics and biases across the life span

“…With age, emotions become more complex; positive and negative emotions are more likely to co‐occur 51 . Emotion regulation—control over one's emotional expression and experience—is maintained and may improve across adulthood, 50,52 unless situational demands overwhelm the aging person's resources 53,54 . The experience and regulation of emotion corresponds to affective decision‐making processes.…”
