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 –

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
