Unformatted text preview: RESCORLA-WAGNER MODEL OF CONDITIONING (1972) The Rescorla-Wagner associative model of classical conditioning expresses four ideas: 1) There is a maximum associative strength that can develop between a CS and a US. The maximum level of conditioning (or the maximum associative strength) is called the asymptote. 2) The associative strength increases with each training trial, but the amount of the increase depends on the level of prior training. 3) The rate of conditioning varies depending on the CS and the US that are used. 4) The level of conditioning is influenced by all previous conditioning with the US (i.e., all prior conditioning of the CS and US being used and also all prior conditioning of other CSs with the same US). Rescorla and Wagner developed a mathematical equation of Pavlovian conditioning based on these four ideas: ∆ V A = K ( λ- V AX ) Associative Strength = Rate of Conditioning (Expectancy - Outcome) of the CS and US BASICS OF THE THEORY The theory is based on the idea that the US has to be surprising in order for learning to take place.
