Annotation	Potential age-related differences in the influence of stimulus repetition on negative and positive priming were investigated in a same-different picture comparison task. 48 young adults (18-30) and 48 older adults (60-75) compared a target picture of a familiar object with a standard picture of a familiar object, to determine whether they were the same or different, while ignoring an overlapping distractor picture presented in a different colour. Negative priming effects increased in magnitude with the repetition of the experimental stimuli in a similar fashion for both age groups. Conversely, positive priming effects decreased in magnitude with increases in stimulus repetition for both age groups. These data suggest that identity-based inhibition develops in a similar fashion from young adulthood to old age. Furthermore, these data add to the growing body of studies that suggest age invariance in the ability to inhibit task-irrelevant information in the environment on the basis of stimulus identity.
