[Semantic activation phenomena in healthy probands and in schizophrenic patients. Analysis on the level of word pairs].
Semantic priming in normal controls and schizophrenic patients can be demonstrated in lexical decision tasks. Data from such a lexical decision task are analyzed with special respect to the question as to whether associative processes in schizophrenic patients are characterized by the occurrence of entirely new associations or by the intrusion of normal associations, i.e., associations which can be found in normal subjects. The analysis of the semantic priming effects of single word pairs demonstrates little qualitative differences between the associations of normals and of schizophrenic patients. This finding provides further support for Maher's hypothesis of activated normal associations in schizophrenic patients. From a methodological perspective, the item-by-item analysis of lexical decision task data can be used to optimize this method.
