Document Summary
No one dimension contributes to a disorder. Perspective on causality is systemic: any particular influence cannot be considered out of context. The following influences are considered in the example of a blood phobia. Behavioural influences: classical or operant conditioning may play a role in creating a behaviour, but not necessarily pushing that behaviour to the point of abnormality, stimulus generalization can have impact on behaviour to new stimuli. Brain fails to receive perfusion it needs and causes loss of consciousness. Developmental critical period is a time when one is more or less reactive to a certain situation than any other time in their life. Genetic contributions to psychopathology genes may not solely determine our development, but they certainly provide some boundaries: environmental influences determine where we go within those boundaries. Diathesis may also be called a vulnerability, which may not become noticeable until the right environmental conditions occurred.
