Recent research has suggested that age-related positivity effects are eliminated under conditions of dual-task load (Knight et al., 2007, Emotion, 7, 705; Mather & Knight, 2005, Psychology and Aging, 20, 554), because the cognitive control resources necessary to enact such preferences are not available when individuals are distracted by competing information. We further examined how older adults' emotional information processing preferences are affected by distracting information by utilizing a within-subjects dual-task measure. Younger and older adults viewed a series of positive, negative, and neutral images both in conditions of full and divided attention. Fixation preferences to valenced images were assessed through eye tracking. Regardless of whether images were viewed in full or divided attention conditions, older adults demonstrated a preference in their fixation for positive and neutral in comparison to negative images. These results provide evidence that older adults' positive fixation preferences may not always necessitate full, cognitive control.
