Dissociating judgment from response processes in statement verification: The effects of experience on each component

This research used the stochastic judgment model of statement verification to demonstrate a dissociation between judgment and response processes and i nvestigated hypotheses about the effects of practice on each component. Dat a from respondents judging statements as true or false under various payoff s supported the dissociation and the following conclusions: Their ability t o discriminate true from false depended on knowledge domain but not on payo ffs. Experience with the domain did not improve this ability but did decrea se the trial-by-trial confidence variability associated with memory search. Practice in a different domain had no such effect. Response criteria depen ded only on payoffs and experience. Criterion variability decreased with cu mulative practice over domains. Most respondents had a bias to say "true" u nder symmetric payoffs, which did not dissipate with experience. Theoretica l implications of the results are discussed.
