ABSTRACT
The literature on thought disorders is extensive. Since Bleuler’s (1911) emphasis on “loosened associations in thought” as the core feature of schizophrenia, the field has been flooded with case reports, empirical studies, and theoretical formulations designed to explain various physiological, interpersonal, and psychological dimensions of disordered thinking. The purpose of this review is to question and examine the place of reasoning and logic in that form of pathology referred to as “thought disorder.” This examination will be framed by a Piagetian model of deductive reasoning development. Related theories of thought pathology, along with the extant research literature, will be explored from this perspective.
