Résumé
Despite the central role that emotional reactivity plays in adaptation, few studies have examined age differences in this capacity under well-controlled laboratory conditions, on the basis of standardized emotion-evoking stimuli and assessing experiential, expressive, and physiological measures. 212 adults ranging in age from 20 to 81 years were exposed to 14 picture series, each lasting 60 s and of a different valence and arousal. We assessed valence and arousal ratings, cardiovascular, respiratory and electrodermalmeasures, facial muscle activity and gaze activity. Here, we present findings for 22 younger (mean age=24.0) and 22 older (mean age=72.1) adults for valence and arousal ratings, systolic bloodpressure (SBP) andheart rate (HR).Compared to younger adults, older adults rated unpleasant seriesmore negatively and showed a smaller range in arousal for pleasant series. SBP linearly increased with increasing appetitive activation. HR showed the expected deceleration from the pleasant to the unpleasant series.However, this effect was clearer for the younger adults than the older adults. For older adults, if something is pleasant, it is also judged to be generally lower in arousal, whereas, if something is unpleasant, it is also judged to be generally higher in arousal. The results for SBP indicate that the association between arousal and sympathetic outflow to the cardiovascular system might be similar in younger and older adults. The results for HR suggest that the parasympathetic activation might be attenuated in older adults as compared to younger adults.
