Theories of Conditioning Flashcards
What is the Rescorla-Wagner(1972) model?
A classical conditioning model that predicts how learning persists based on how surprising the US is.
What is extinction?
Extinction is the disappearance of a previously learned behaviour when the behaviour isn’t reinforced.
Wagner modified Rescorla-Wagner in 1981 how?
He proposed that how surprising the CS is, is as important as the US. Animals respond to novel stimuli with an orienting response. With repeated presentation, the OR declines (habituation).
And the associability of the CS declines( latent inhibition).
Who said that animals learn more about good predictors in the future?
Mackintosh
Who said that stimuli with established consequences are processed in automatic mode and can’t enter new associations & stimuli with unknown consequences are processed in controlled mode and can enter new associations.
Pearce-Hall (1980)
What did the Rescorla-Wagner model originally focus on and what was later taken into account?
The surprisingness of the US. The surpisingness of the CS was later taken into account.
What are the different components of the Rescorla-Wagner equation?
- The change in strength of the association.
- salience of CS.
- magnitude of US.
- strength of CS-US association.
What is the effect of US magnitude on learning?
The larger the magnitude of the US, the greater the overall associative strength and learning is more rapid in the beginning then it slowly levels off.
What is the effect of CS salience on learning?
Associations made more rapidly in the beginning. The magnitude is reached very quickly and then it levels off.
