Tutorial #2. Behaviourisms.

Take a look at George Graham Behaviourism in Stanford Encyclopedia of Philosophy

+ Three senses of Behaviourism

1) Philosophical behaviourism:
Having a mind is a matter of exhibiting, or having the propensity to exhibit, certain appropriate patterns of observable behaviour.

2) Psychological behaviourism:
The meanings of psychological terms derive from operational definitions based on observable behaviour.
E.g. the meaning of mental expressions such as 'pain' or 'belief' are to be explained away by reference to publicly observable behaviour, not to internal states.

3) Methodological behaviourism:
- The only admissible data for the science of psychology are behavioural data.
-Psychological theories\explanations must not invoke internal\psychological states; nor should references to such states in deriving predictions about behaviour.
- Psychological theories must not make reference to inner mental states in formulating psychological explanations.
