Document Summary
Need to be able to discriminate to survive (finding food, finding mates, avoiding poisonous substances etc. ) Pavlov used a study in 1917 with circle & square. Theories of discrimination learning: relational learning & transposition. Kinnaman & kohler: one of the earliest theoretical accounts of discrimination proposed that signals for reward and non-reward bear a relationship together, which will help solve discrimination. Kohler tested his argument by using chickens and training them to peck at the light card (reward) but not the black card (non-reward) Transposition test: a test to determine if a discrimination between two stimuli is based on the relationship between them, by presenting two test stimuli that share the same relationship: spence: Presented the first formal theory of discrimination learning. Proposed= if an animal is rewarded for approaching a stimulus, then the tendency to repeat the response in the presence of the stimulus will be increased.
