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 –

Operant Conditioning or Instrumental Learning

Edward L. Thorndike (1913) – the law of effect – puzzle box and learning curve

B.F. Skinner (1953) – principle of reinforcement– Operant chamber – “Skinner Box” – – Emission of response – Reinforcement contingencies – antecedents, behaviors, and

consequences (ABC)– Cumulative recorder –

Consequences: Reinforcement and Punishment

Increasing a response:– Positive reinforcement = response followed by rewarding

stimulus– Negative reinforcement = response followed by removal of

an aversive stimulus• Escape learning• Avoidance learning

Decreasing a response:– Punishment– Problems with punishment – third variable problem and

correlation between punishment and aggression –

Observational Learning and theMedia 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
