Semantic priming in thought disordered schizophrenic patients

Abstract

Groups of thought disordered (TD) and non-thought disordered (NTD) schizophrenic patients, unipolar affective patients and normal controls performed a lexical decision task involving the recognition of words immediately preceded (primed) by either an associated or an unrelated word. Significant increments in recognition speed in the associated prime condition were found in all groups, with significantly greater gain by TD schizophrenics than by others. These findings are consistent with network models of associational activation and lend support to an attentional deficit hypothesis for schizophrenic language functioning.
