Previous research has suggested that aging is associated with increased distractibility and

effect of unintentional recognition of to-be-ignored distractor images on intentional

unintentional versus intentional recognition. This research involved comparing old (60-76)

neurocognitive process during intentional recognition. This effect may reflect a

age groups for both intentional target recognition and unintentional distractor recognition.

memory are affected by aging and intentionality, and suggest that future research should
