How would Rescorla-Wagner explain inhibitory conditioning? How would Pearce-Hall explain the same phenomenon?
Answer:
Rescorla–Wagner model ("R-W") is based on classical
conditioning.
It is based on in relation between unconditioned stimuli(US) and
conditioned stimuli (CS).
According to this subject is surprised due to US before he is
conducted. But after he is conditioned he no longer feel any
surprise. This happened due to production of coming of US by the
CS.
It explains the experimental phenomenon of the blocking
effect.
According to Pearce-Hall model, situations in which an event occurs
is a sign for the consequences of it.
This model was based on the classical conditioning (pavlovian)
context.
In it signal is assume as a CS (conditioned stimuli) & the
unconditioned stimulus (US) are the consequences.
Hence it operate with the conditions required for the development
of an associative bonding between the CS and US’s central
representations.
According to Pearce-hall model, variation (Δ) in the associative
strength (V) of a conditioned stimuli as result of pairing of US
& CS.
According to following equation this pairing is governed:
ΔV=S.α.λ
