Subject matter and poetic devices in psychotics' poetry

It has long been supposed that there is a connection between the mental processes of psychosis and those of creativity. The present study aimed to investigate this idea by means of a comparison between the poetic output of psychotics and that of normals, taking as its starting-point the notion that if there are observable differences between these two groups in terms of subject matter and linguistic features, this would suggest that creativity and psychosis are not to be identified with each other. Eighty poems by contemporary, non-professional poets (40 by psychotics and 40 by normals) were analysed on 11 different dimensions. The two samples of poems were highly similar on most of the dimensions investigated. The main differences found were in the incidence of self-analysis as a theme, reference to proper names and specific locations, and in the proportion of metaphors which fell into the category 'psychological/physical'. The two latter differences appeared to be largely a product of the first. It was concluded that although 'normal' and 'psychotic' poetic activities are not identical, they are closely related. This may be either because general poetic creativity does have psychotic features, or because the poetic function of language was relatively spared in at least this sample of psychotics.
