PS280 Lecture Notes - Lecture 2: Homeostasis, Hypoglycemia, Headache
Document Summary
There are practical implication if we find causes in this field. We want to: explain etiology, identify the factors that maintain the behaviour, predict the course of the disorder, design effective treatments. Many different theories about mental disorders have been proposed. Biological, psychodynamic, learning (which includes behavioural or cognitive-behavioural theories), cognitive, humanistic-experimental and socio-cultural. Faulty claim that the action of the entire system is determined or caused by one or other of the parts. Human behaviour is the produce of the interaction of many factors. Focus on biological factors without considering the role of environmental factors. In an extreme form, it assumes that if the cause is biological interventions will not address the problem. Examples where psychological and environmental interventions have a significant impact on disorders with biological determinants: phenylketonuria: enzyme deficiency due to abnormality in chromosome 12. Causes toxic build up on phenylalanine, which is toxic to the developing brain.
