What is the equation for the Rescorla-Wagner Model?

VΔ= ɑβ (λ-Vt)

what is this symbol called Δ

delta

in the Rescorla-Wagner Model what does delta equal?

learning

in the Rescorla-Wagner Model what does alpha mean?

salience of the CS

in the Rescorla-Wagner Model what does beta mean?

salience of the US

in the Rescorla-Wagner Model what does lambda mean?

the total amount of learning that can occur

in the Rescorla-Wagner Model what does alpha equal?

always 0.5

in the Rescorla-Wagner Model what does beta equal?

always 1

in the Rescorla-Wagner Model what does lambda equal?

any number exam will be 10

If a soft tone occurs what level of salience is alpha?

low level

if a large amount of food is given what level of salience is beta?

High level

in the Rescorla-Wagner Model what does V signify?

associative strength between the CS and the US

in the Rescorla-Wagner Model what does sub t signify?

the specific trial number or time step being analyzed

what is this symbol called λ

lambda

how many units of learning would this trial produce?

ΔV=0.5x1(10-0)

5

if 5 units of learning occured on the second trial what would the V sub t equal?

5

True or False: when calculating learning between trials you must add how many units of learning were aquired between each trial

true

True or False: The rescola-wagner model does account for the typical acquisition curve

true

what is compound conditioning used to study?

how different stimuli compete for associative strength

what is serial overshadowing?

a form of associative learning interference where a second stimulus (B), appearing after a target stimulus (A) but before an unconditioned stimulus (US), impairs the conditioning of stimulus A

in the Rescorla-Wagner Model which peice of the equation signifies what the subject expects?

V sub t

in the Rescorla-Wagner Model which peice of the equation signifies what the subject gets?

lambda

true or false: If there is no difference between what the subject expects and what they get learning will stop

true

What is conditioned excitation?

a CS-US pairing

What is conditioned inhibition?

A CS that predicts that the US will NOT occur

What is this an example of?

If there’s a hungry puppy and they know a light produces food, meaning the dog likes the light because they get food when they are hungry, but there is no food when there is a tone which makes the puppy mad

conditioned inhibition

What is the Rescorla-Wagner Model good at predicting?

Classic acquisition curve 

Conditioned inhibition

Key aspects of compound conditioning include…

overshadowing

blocking

associative strength

what is overshadowing?

When one stimulus in the compound is more intense or salient, it will elicit a stronger response, overshadowing the weaker stimulus.

what is blocking?

Previous conditioning of one stimulus can prevent a new stimulus in a compound from becoming associated with the unconditioned stimulus.

what is associative strength?

The total associative strength of the compound is shared between the individual components, meaning the strength of the combined stimulus is generally less than the sum of their individual strengths.

what is the simultaneous overshadowing equation?

CSa+CSb=US

what is the serial overshadowing equation?

• CSa+US then CSb+US

what is compound conditioning?

a classical conditioning procedure where two or more conditioned stimuli (e.g., a light and a tone) are presented together simultaneously with an unconditioned stimulus (e.g., food or shock) to elicit a conditioned response.

what is cousins with overshadowing?

blocking

how does the rescorla-wagner equation change what it is the first trial in an extinction trial?

ΔV=0.5x1(0-10)
