2304 Bio: Discrimination & Categorisation 0.0 / 5 ? PsychologyVisual SystemUniversityNone Created by: Paula379Created on: 09-02-19 12:49 What is simple discrimination? S+ and S- = in general differential responding; animals can discriminate between the 2 stimuli. 1 of 16 Define 'Successive discrimination.' Present 1 of the stimuli & see how the animal responds. 2 of 16 Define 'Simultaneous discrimination.' Present 2 stimuli & see which the animal approaches. 3 of 16 Define 'Conditional discrimination.' Reinforce different responses in the presence of different stimuli. 4 of 16 What is generalisation? Some response occurs to stimuli that are physically similar to S+ but not identical to it. 5 of 16 What is generalisation decrement? Response to other stimuli is less than that to S+ itself. 6 of 16 What is the generalisation gradient? A graph generalised responding to values on a stimulus dimension. 7 of 16 What is peak shift? Responding may be greater to a stimulus other than S+- stimulus dimension. 8 of 16 What is transposition? If a discrimination between S+ & S- is trained & then S- is tested vs. S+, S- may be chosen. 9 of 16 What is transfer along a continuum? Training an easy discrimination on a dimension can help the animal acquire a difficult one. 10 of 16 What did Wills & Mackintosh (1999) find? Pigeons learn to discriminate between light & dark. 11 of 16 What did Lawrence (1952) find? Rats find it difficult to distinguish between similar shaded tiles. 12 of 16 What are 2 categories of abstraction? Perceptual & logical categories. 13 of 16 What did Herrnstein & Loveland (1964) find? Pigeons learn to peck in presence of picture of a person & withhold pecks in presence of a picture with no person in it. 14 of 16 What is rote learning or absolute discrimination? Claimed to be ruled out by successful transfer to new instances. 15 of 16 What is multiple linear feature model? Predicts a superreleaser (prototype) effect that doesn't always occur. 16 of 16
