PS261 Chapter Notes - Chapter 4: Classical Conditioning, Habituation, Comparator
Document Summary
What makes effective conditioned and unconditioned stimuli: this is the most basic question one can ask about classical conditioning. Novelty of conditioned and unconditioned stimuli: highly familiar stimuli elicit less vigorous reactions than do novel stimuli. The us-preexposure effect: conditioning proceeded faster for the lever paired with the novel food than for the lever paired with the familiar food. Intensity: most biological and physiological effects of stimulation are related to the intensity of the stimulus input, stimulus salience. Cs-us relevance, or belongingness: another variable that governs the rate of classical conditioning is the extent to which the cs is relevant or belongs with the us, garcia and koelling (1966) conducted a study with rats. Learning without an unconditioned stimulus: there are two different forms of classical conditioning without a us, higher-order conditioning, sensory preconditioning. Cs2 (movie theatre) will also elicit the conditioned response (second-order. Us: the conditioned stimulus comes to function much like the us did previously.
