Ch 5 Vid 4 Rescorla-Wagner Theory

Raskorla-Wagner theory

The leading theory of classical conditioning that explains fundamental principles and predicts phenomena that other theories cannot.

Asymptote in conditioning

The peak amount of conditioned response that occurs and does not exceed during conditioning.

Associative value

The limited amount of potential of an unconditioned stimulus that can be distributed among conditioned stimuli.

Delta V

Symbol representing the change in strength of the conditioned stimulus's association in the Raskorla-Wagner formula.

Mathematical formula of Raskorla-Wagner theory

Delta V = alpha * beta * (lambda - V), predicting the change in the conditioned response strength.

Salience

The strength or prominence of a conditioned or unconditioned stimulus in the conditioning process.

Blocking

A phenomenon in which a previously conditioned stimulus inhibits the conditioning of a new stimulus when presented together.

Overshadowing

A phenomenon where a more salient stimulus reduces the conditioning effect of a less salient stimulus.

Higher-order conditioning

The process in which a neutral stimulus becomes conditioned by being paired with an already conditioned stimulus.

Over expectation effect

A phenomenon where the combined associative values of two conditioned stimuli do not equal the sum of their individual associative values when conditioned together.

US revaluation

Changing the value of an unconditioned stimulus, impacting the strength of the conditioned response.

Inflation in conditioning

Increasing the associative value of an unconditioned stimulus, enhancing the conditioned response.

Deflation in conditioning

Decreasing the associative value of an unconditioned stimulus, reducing the strength of the conditioned response.
