Formatted Abstract/Summary
Viewing affective pictures elicits reliable patterns of physiological change in the somatic, visceral, and central systems of children and adults that covary with reports of affective valence and arousal. Research that has directly investigated the relationship between emotion and overall physiological change in the context of healthy ageing is currently equivocal. Australian older and younger adults’ subjective and physiological reactivity to affective pictures from the International Affective Picture System were compared. Across three experiments, younger (18-25 years), middle aged (31-48 years) and older (52-93 years) participants viewed and provided ratings of valence, arousal, dominance and fear for subsets of affective pictures using the Self-Assessment Manikin. Eyeblink reflex, skin conductance, heart rate, corrugator and zygomaticus activity were recorded during picture viewing in Experiment 3. Affective responding is assumed to be activated by basic appetitive and defensive motivational systems. Across the three experiments, there were no age related differences in subjectively rated pleasantness; older adults provided reduced arousal ratings for pleasant pictures and showed little differentiation among the pleasant high, medium and low arousal categories. Differences in emotion driven physiological responding were evident in both age groups. Blink magnitude of younger adults did not differ during pleasant and unpleasant pictures, however, older adults showed an enhanced blink magnitude during unpleasant pictures. Both age groups showed largest SCR activity during high arousal pictures. In older adults, corrugator activity was larger when viewing unpleasant compared to neutral pictures. Zygomaticus activity was enhanced for younger adults during pleasant pictures. Older adults did not show emotional modulation of zygomaticus activity. Taken together, these findings suggest that older people differ in subjective and physiological emotional reactivity compared to younger people.
