Hard determinism- the view that all behaviour is caused by forces outside a persons control - genetically predisposed, had traumatic experience as a child, has experience with role models,
soft determinism- the view that behaviour is still determined by internal and external influences but, an individual can still exercise some control over it- influenced by many biological, environmental and unconscious factors but has made a conscious choice to behave that way
biological determinism- Biological determinism (i.e. the biological approach) is the view that behaviours are determined by biological processes
Biological determinism- Genetics: Many psychological disorders and behaviours (e.g. schizophrenia, OCD, anorexia, and alcohol addiction) seem to have a strong genetic component as evidenced by twin studies.
Biological determinism- Hormones: Increasing levels of the hormone testosterone, for example, make people behave more aggressively and vice versa.
Biological determinism- Biological structures: Brain scans show that people with OCD often have increased activity in the prefrontal cortex of the brain.
Biological determinism- Physiological processes: The autonomic nervous system has a big influence on behaviour (e.g. increased heart rate before a date makes you behave like a nervous wreck) but is not under conscious control.
