Persistence of stimulus-response compatibility effects with extended practice.
The influence of extended practice on stimulus-response (S-R) compatibility effects was investigated. Three experiments, each extending over a period of 8 sessions, were conducted. The nature and degree of compatibility was manipulated across experiments. In all experiments, a persistent effect of S-R compatibility on reaction times was observed. Thus, the lower bound for reaction times appears to be less for compatible assignments than for incompatible assignments. This persistence of S-R compatibility indicates that the initial codings used to perform a novel task continue to exert an influence on later performance.
