PSYC214 Lecture Notes - Lecture 8: Stimulus Control, Classical Conditioning, Discrimination Learning
Document Summary
Experimental paradigms to measure stimulus control: differential responding and stimulus discrimination, eg. In other words can we detect the stimulus being presented. If not then how can our behaviour come under its control: organism"s sensory capacity and orientation, relative ease of conditioning, presence of other cues in the environment effect conditioning (ie. creates competition for stimulus control, eg. Overshadowing - pavlov: types of reinforcement, positive vs negative reinforcement, eg. Foree & lolordo 1973: pigeons pressing foot treadle in presence of compound stimulus (light+tone, press foot treadle - shock aviodance (neg. reinf) or food (post reinf, test: light and tone presented separately. Stimulus discrimination training - can be used with pc and ic: example: differential fear (aversive) conditioning in humans, cs+ and cs- (faces, us (shock) How does learning affect stimulus: example instrumental conditioning. Special case of a multiple schedule of reinforcement (i. e. different schedule of reinforcement during different stimuli in ic procedure)
