摘要	Inhibition deficit plays a crucial part in cognitive aging; however, few studies have systematically investigated the plasticity of various inhibitory processes among older adults. We studied the plasticity of 3 inhibitory processes (access, deletion, and restraint) and the extent of far transfer of inhibition training to other general cognitive abilities. Thirty-six participants (aged 60 years and above, M = 70.06, SD = 5.53) were randomly assigned to an adaptive training group that received 12 sessions of training covering 3 inhibitory processes or an active control group that received 4 sessions of mental health lectures. Participants in both groups completed pre-and posttest assessments, in which behavioral and electrophysiological measures were used to evaluate potential transfer effects. Direct training gains were observed for trained tasks of all inhibitory processes, but near-transfer effects were only found within untrained tasks associated with deletion at a composite score level. Furthermore, far-transfer effects were demonstrated for fluid intelligence (Gf) but not for working memory or other general cognitive abilities. Near transfer to deletion and far transfer to Gf persisted at a 3-month follow-up assessment session. We discussed differences in plasticity between the 3 inhibitory processes as well as their possible associations with far transfer to Gf.
