Classical Conditioning Theories
Rescorla-Wagner Model : ΔVn = c(λ – Vn-1)
ΔVn = Change in learning since last trial c = How much of a complete association between CS & US is
subject capable of learning on a given trial (0 – 1) λ = Total amount learnable – estimated by measuring max
performance of highly trained subjects (depends on intensity of US)
Vn-1 = Amount of learning that previously occurred to the US
Trial
