Psychometric & psychophysiological measures for schizotypy, creativity & psychoticism

Abstract

This thesis was initiated as a study of personality traits and electrophysio­logical dysfunctions which could underlie schizophrenia and yet which would also be detectable in the normal population, i.e, biological risk mark­ers rather than simple state signs. As it progressed, the thesis came more to focus on individual differences in thinking style including psychoticism as a variable affecting attention, schizotypy, as it conveys a cognitive slippage component which affects the development of thought, and also creativity as it affects the generation of associations. Part one of the thesis reports the de­velopment of scale measures of schizotypy and of creativity.
