Plasticity of inhibition in older adults: retest practice and transfer effects.


This study assessed plasticity of inhibition in older adults through examining retest practice effects in a six-session training paradigm using the Stroop task and the training-induced transfer effects to a range of cognitive measures. Fifty-six older adults (aged 60-84 years, mean = 71.05, standard deviation = 6.17) participated in this study. They were evenly assigned to one of four groups: summary feedback, individualized and adaptive feedback, no-feedback, or a no-contact control group. The results suggest that older adults are able to improve inhibition across retest sessions but unable to transfer the retest practice effects to other tasks. In addition, the improvement is not item specific and feedback does not appear to moderate the magnitude of the training benefits; however, feedback does appear to reduce interference variance across retest practice sessions.
