title: The relationship between formal thought disorder and executive functioning component processes.
abstract: In 2 studies, associations between formal thought disorder (FTD) and 2 components of executive functioning, processing of context and interference resolution, were investigated. One study, involving people with schizophrenia, examined associations between performance on processing of context (N-back) and interference resolution (interference in Steinberg probe recognition) tasks and FTD. The second study, involving nonpsychiatric participants, was an analogue study that examined the effects of simulated processing of context (performance of 1-back with distraction) and interference resolution (telling new stories about previously seen pictures) deficits on FTD in a speech production task. In both studies, processing of context deficits predicted FTD. Moreover, in both studies, the effect of processing of context deficits on FTD was especially pronounced when combined with interference resolution deficits.
