Hyperactivity of associations in psychosis.
Disordered associative processes have long been regarded as central to the psychological description of psychotic states such as acute schizophrenia. Previous work is briefly summarised concerning the idea that hyperactive associative processes of thought underlie many of the symptoms of psychosis. The idea is developed further, with respect to several features of the psychotic state. Schneiderian symptoms are seen as a consequence of hyperactive associations of thought, combined with perceptual hypersensitivity characteristic of many psychotic individuals. Anxiety in psychotic states is seen as arising from the great ambiguity of mental images when associations are loosened. A vicious circle between high anxiety and hyperactive associations is postulated. The slow and variable response to neuroleptic treatment is seen as being determined in part by the dynamics of change of the memories acquired during a period of hyperactive associations.
