Classical Conditioning: More Terminology

Trial = pairing of UCS and CS

Acquisition = initial stage in learning

Stimulus contiguity = occurring together in time and space

3 types of Classical Conditioning

– Simultaneous conditioning : CS and UCS begin and end together

– Short-delayed conditioning : CS begins just before the UCS, end together

– Trace conditioning : CS begins and ends before UCS is presented

 Classical Conditioning in Everyday Life

– Conditioned fears

– Other conditioned emotional responses

– Conditioning and physiological responses

– Conditioning and drug effects –

Observational Learning and the

Media Violence Controversy

 Studies demonstrate that exposure to TV and movie violence increases the likelihood of physical aggression, verbal aggression, aggressive thoughts, and aggressive emotions

 The association between media violence and aggression is nearly as great as the correlation between smoking and cancer – third variable problem
