Abstract:
This chapter presents an account of the core signs and symptoms of schizophrenia based upon the Interacting Cognitive Subsystems mental architecture. Four sources of variation are assumed to underlie information processing activity: variation in self-representation, variation in modes of processing, variation in rates of change in the content of mental images; and variation in the synchronisation of exchanges between subsystems. The account proposes that processing exchanges between subsystems specialised to handle propositional and implicational meaning become asynchronous. At short feedback delays, the constituents of implicational representations become intermingled, providing conditions for thought disorder. At longer feedback delays, stream separation would occur leading to conditions allowing the formation of abnormal implicational models and attributions of their origins. Variation in actual symptom expression is then related to variations in modes of processiong, rates of change in image content and self-representations
