The role of cognitive and affective flexibility in individual differences in the experience of experimentally induced heat pain

Adaptation to the context in which we experience pain requires cognitive flexibility (CF) and affective flexibility (AF). Deficits in both flexibility types may be precursors of more intense and prolonged pain. This study aimed to examine the relation between CF and AF, and the experience of experimentally induced pain. Furthermore, correlations between behavioral and self-report measures of flexibility were explored. CF and AF were assessed with task-switching paradigms, using neutral (numbers ranging from 1 to 9, excluding 5) or affective stimuli (positive and negative pictures), respectively. Pain sensitivity measures, such as pain threshold (degrees C), pain tolerance (degrees C), and retrospective pain experience ratings (Visual Analog Scale) were assessed for an experimentally induced heat pain stimulus. Self-reported CF was measured with a questionnaire. Results demonstrated no associations between the flexibility constructs and any of the pain outcome measures. Correlations between the behavioral and self-report measures of CF were absent or weak at best. Current results are discussed against the background of methodological considerations and prior empirical research findings, suggesting the contribution of AF in especially the recovery from pain.
