The Preservation of Response Inhibition Aftereffects in a Location-based Spatial Negative Priming Task: Younger Versus Older Adults
Overview
Affiliations
Younger (M = 21 years) and older (M = 74 years) adults completed a spatial negative priming (SNP) task where (central) events (i.e., target or distractor) are presented in trial pairs: first the prime and then the probe. Free-choice trials were included (1 location: 2 permissible responses), which allowed us to isolate response inhibition and its consequent inhibitory aftereffects (i.e., current inhibition interferes with later related processing-e.g., SNP). The inhibitory aftereffects associated with the suppression of responses activated by distractor-occupied locations were highly comparable for younger and older adults; including similar SNP effect sizes, a significant tendency to select against former distractor (inhibited) responses (within-hand finger options) on free-choice trials, and latency delays attributable solely to the use of self-selected distractor responses. Aftereffects generated by target-occupied prime trials locations were also the same for both age groups; recently executed target responses were selected for and produced faster responding (within hand). Aftereffects were absent on between-hand free-choice trials and, overall, response selection determinants on free-choice trials matched for older and younger adults.
