Approaches of Dysfunctional Behaviour

Therefore any dysfunctional behaviour is learnt, by operant conditioning, classical conditioning, or social learning. This places the responsibility on us to ensure that we do not ‘teach’ dysfunctional behaviours to others. * Biological
The biological approach, which is part of biopsychology, would favour the nature side of the nature-nurture debate. Biological explanations of behaviour assert that something in our biology is the fundamental cause of dysfunctional behaviour. There could be genetic cause, or a malformation of brain structures. * Cognitive
The third approach to explain dysfunctional behaviour is that of cognitive psychology, which sees our behaviour as being a consequence of some internal processing of information. Much like a computer, we...
