Cued fluency protocol reveals dynamic symptomatic-dependent processes of goal-directed behaviours in schizophrenia.

Abstract

Differential impairments of willed actions and routine behaviours are the subject of many studies into schizophrenia. These impairments in generating and controlling goal-directed behaviours are reported in studies showing the effect of cueing in cognitive or motor tasks in people with schizophrenia. The aim of this study was to assess the performance of people with schizophrenia in a cued fluency protocol reworked to fit the concept of goal-directed behaviour. The extent to which results could be better explained by goal-directed generation issues, according to a symptomatic framework, than by semantic retrieval or semantic processing impairments, was also investigated.
