title: Decreasing complexity of affective space in older adults lower on cognitive control: affective effects in a nonaffective task and with nonaffective stimuli.
abstract: Many theoretical accounts predict that as people age, they rely increasingly on affect. At least one account (Dynamic Integration Theory) makes the additional prediction that an accompanying effect of aging is a narrowing of affective space. These predictions were tested in the context of the relatively automatic low-level cognitive process of lexical access (auditory word recognition). Experiment 1 used emotion words and Experiment 2 used nonemotion words. Both experiments provided support for both predictions. Compared to younger adults (ns = 36 and 56), older adults (ns = 36 and 54) showed larger but less complex effects of dimensions of affective connotation. In addition, older adults with more cognitive resources showed a data pattern like that of younger adults, while those with fewer resources did not. Affective effects emerge even in nonaffective contexts. The tight link between affect and cognition is discussed.
