Document Summary
Types of learning: classical conditioning (respondent, pavlovian) Stimulus elicits a response that has survival value. Occurs when neutral stimulus is paired with biologically relevant stimulus. Bell in relation to food, sound in relation to pain. Shifted from digestion to salivary reflex: operant conditioning, observational learning. Unconditioned stimulus (us)- biologically relevant stimulus (food, loud sound, air puff) Unconditioned response (ur)- reaction to the us. Conditioned stimulus (cs)- stimulus paired with the us. Conditioned response (cr)- response elicited, after repeated pairings, by the cs (resembles the. Extinction- eliminates the us, cs no longer elicits cr. Spontaneous recovery- after delay, cs occurs without us, extinguished response temporarily reappears. Stimulus generalization- stimuli similar to the cs elicit the response. Mary jones (1924: watson student, peter, 3year old, afraid of rabbits. Counterconditioning: pairing a cs that has become capable of evoking a fearful response gradually with a us that elicits a pleasant response, 2 types. Imagine the cs while practicing relaxation techniques.
