L6/7 Occasion Setting Flashcards
No L6
What is a ‘hierarchical association’?
An association that seems to activate or inhibit other associations.
What is a discrimination procedure?
A conditioning procedure where an animal has to discriminate between two situations.
One situation usually involving a US, the other does not.
In what situation do hierarchical associations typically seem to be learnt?
What conditioned stimuli are presented serially.
(one after the other)
Rather than when presented simultaneously.
What is a ‘occasion setter’?
Discrete stimuli or contexts that disambiguate operant relations.
In cases where stimuli or responses are “sometimes” associated with events, occasion setters can provide discriminant information that resolves the ambiguity of the antecedent.
In a discrimination experiment, what is the feature?
The feature that differentiates the two trial types (if A is presented every time and B only some times, B is the feature)
What is Simultaneous Feature Positive Discrimination?
When the ‘feature’ is paired with the US.
What typically happens to the ‘feature’ in simultaneous feature positive discrimination trials?
The feature becomes excitatory.
What is a Serial Feature Positive Discrimination trial?
Serial means the stimulus is presented one after the other.
Rather than simultaneously
What happens to stimulus A in this serial feature positive discrimination trial?
A becomes excitatory.
Does B become excitatory in this serial feature positive discrimination trial?
No, it seems to activate the A-> US association but is not excitatory itself.
What is the difference between simultaneous and serial positive discrimination tests and simultaneous and serial negative discrimination tests?
Positive: US is paired with the feature
Negative: US is paired without the feature
Negative is also called conditioned inhibition.
What will Rescorla-Wagner’s model predict for this experiment?
Is it accurate?
A will become excitatory
B will become inhibitory.
This is a correct prediction.
What is a summation test?
You pair the inhibitor with a different excitor.
The inhibitor should suppress the conditioned response generated by any excitor.
What is a retardation test ?
You condition the inhibitor by repeatedly pairing it with the US.
The inhibitor should condition (become excitatory) slowly.
What will Rescorla-Wagner’s model predict on this serial feature negative discrimination model?
Is this a correct prediction?
Rescorla-Wagner would predict B to be an inhibitor, it does not count for presentation order of the stimulus.
It is not correct?
B is no longer inhibitory, it can turn into an excitor.
