Chapter 4. Learning I. Classical Conditioning a. = acquiring a new response to a previously neutral stimulus that reliably signals the arrival of an unconditioned stimulus b. Reflex – a stimuls-response pair in which the stimulus (unconditioned) automatically elicits the response (the unconditioned response) [food in mouth, saliva] c. Conditioned stimulus [the tone] to the conditioned response [salivating] d. Delayed conditioning a classical conditioning procedure in which the conditioned stimulus precedes the unconditioned stimulus and remains present until after the unconditioned stimulus is presented so that the two stimuli occur together [toned turned on and NOT turned off until the meat powder was in the dog’s mouth]; MORE effective than trace e. Trace conditioning – the conditioned stimulus precedes the unconditioned stimulus but is removed before the UCS s presented so that the two do not occur together [tone on then off, then meat powder] f. Little Albert Study – John B. Watson, founder of behavioral psych i. White lab rat and baby; baby was not afraid of rat until loud noise clanged when he touched it; albert adopted the fear-avoidance response; only took seven pairings for albert to cry upon SEEING rat ii. Mary Cover Jones, a student of Watson, demonstrated that fear could be deconditioned; Elsie Bregman showed limits to conditioning fear responses (infants wouldn’t fear inanimate objects) II. General Learning Processes in Classical Conditioning a. Extinction and Spontaneous Recovery i. Extinction – the diminishing of the CR when the UCS no longer follows the CS ii. Spontaneous recovery – a partial recovery in strength of the CR following a break during extinction training b. Stimulus Generalization and Discrimination
