rejects reductionism. Behaviourists explain human and animal behaviour and learning through simple stimulus connections, people who support cognitive approach think it's too simplified as we process information internally not externally, and it is more complex than they think. Sigmund Freud describes it as conflict between the 3 structures of behaviours, whereas humanistic psychologists advocate for holism suggesting a subjective experience can only be considered by a whole person. This suggests that it can have more validity than other approaches as it takes the real world into context
