Intelligence and Complexity Management: From Physiology to Pathology. Experimental Evidences and Theoretical Models

Intelligence is the most evident of the emergent properties of the evolution of life on the hearth. The thought process of humans is still not very understood as background information processing. Most of the observations come from clinical practice where an impairment of the thought process is believed as the back ground phenomena of behavioural disfunctions. Data from clinical observation, patients self reports and antypsychotic treatment efficacy are the main source of present models of thought process. Other modeling arise from experimental psychology and cognitive sciences. Just in the last 20 years new data are available by pooling together neuropsychological reasults with clinica observations, and self reports. In present work the statistical structure of such pooling of data is presented from observations performed in normal, psychiatric patients and people with mental retardation. A model of thought process is presented taking into account both this statistic structure and clinical observations. Two main component are suggested as main modules of thought process: the “Rule Inference Processor” and the “Input Organizing Processor”. Impairment of one of both processor can explain the formal thought disorders observed in clinical diagnostic group of patients.
