Document Summary

What is the difference between classical conditioning and instrumental conditioning. Classical conditioning of love : don byrne: reinforcement-affect model, ex. arousing stimulus--->positive feelings--->positive evaluation--->pair neutral stimulus(stranger) with arousing stimulus(music)--->positive evaluation of stranger, may and hamilton (1990): Female students rate photos with music playing in the background. Positive music increases attraction, negative music decreases attraction. Pair primary cs with another neutral stimulus (secondary stimulus: not very effectivecs-ucs bond is no longer enforced, the cr extinguishes. Extinction trials: cs no longer paired with ucs, decreases in response strength, cs loses cue value, cs-ucs bond not unlearned. Generalization degree of responding to stimuli similar to training stimulus. Instrumental (operant) conditioning: association of a stimulus and a response, choose and reinforce target response---> response contingent. S-r bond is strengthen by reinforcement--->law of effect. Rat presses bar--->reward (food pellet) is delivered--->bar pressing increases: negative reinforcement. Rat presses bar--->aversive stimulus (shock) removed--->bar pressing increases.
