Many experimental tasks include distraction, either intention-ally (e.g., in visual search and flanker tasks; Eriksen & Schultz, 1979; Treisman & Gelade, 1980) or unintentionally (e.g., in classic perceptual speed tasks; Lustig, Hasher, & Tonev, 2006). In either case, relative to younger adults ’ performance, older adults ’ performance on a concurrent target task is differen-tially influenced by the presence of distraction, which usually disrupts performance of the target task (Lustig et al., 2006; Rabbit, 1965) but occasionally facilitates it (May, 1999). Such findings are consistent with the idea that the bandwidth of attention (Jonides et al., 2008) is greater for older than younger adults. This phenomenon is due, at least in part, to reduced inhibitory regulation, which otherwise suppresses representa-tions of nonrelevant information (Hasher, Zacks, & May, 1999; Wühr & Frings, 2008)
