PSY1020 Chapter Notes -Interstimulus Interval, Conditioned Taste Aversion, Classical Conditioning
Document Summary
Learning refers to any enduring change in the way an organism responds based on its experience. An environmental stimulus leads to a learned response. Through the pairing of an unconditioned stimulus (ucs) with a previously neutral. Any unconditioned response (ucr) is a response that doesn"t have to be learnt. Conditioned responses (cr) (e. g. , taste aversion and immune system response) are learned reflexes that can produce both adaptive and maladaptive. Stimulus generation occurs when an organism learns to respond to stimuli that resemble the cs with a similar response. Stimulus discrimination is when an organism learns to respond to a restricted range of stimuli. Extinction is when a cr is weakened by the presentation of cs without the ucs. Influencing factors; interstimulus interval (the degree to which presence of cs is predictive of ucs), history and prepared learning. Learning to operate on the environment and produce a consequence. Reinforcement: the consequence that increases the probability of a response.
