(Chpt.5) Flashcards
Novelty of CS and US
Familiarity of the CS and US will have an impact on subsequent learning of an CS-US association
tone and food
Latent inhibition (look @notes)

Effective CS and US
Salience refers to the significance or noticeability of the stimulus the more salient a CS or US is the better the learni
ing
Reciprocal Overshadowing
When 2 stimuli are paired together each one will inhibit learning about the other if the stimuli differ in salience then we will see better conditioning to the more salient stimulus

Effective CS and USI
it is not always necessary to have a US for associates to form

Second order conditioning

Associative Strength is a theoretical construct the is proportional to the level of conditioned responding that is expected to occur to a stimulus.
True
A conditioned inhibitor has ___ associative strength (postive/negative)
negative
Pre exposure event
Non-reinforced pre-exposure of a CS will ___ learning of an excitatory conditioned response to that same CS
Retard (slow down)
Latent Inhibition and the US pre-exposure effect produce the same behavioral outcome
True
In latent inhibition, the CS is pre-exposed in the absence of the US. In US pre-exposure, the __ is pre-exposed in the absence of the __.
US,CS
How noticeable a stimulus is is referred to as what?
Salience
When two stimuli are paired together and are followed by reinforcement, this results in each stimulus restricting learning about the other. This phenomenon is called:
Reciprocal Overshadowing
