Conditioned Inhibition
A conditioned inhibitor is a stimulus that predicts the absence of an outcome.
How do you learn that a stimulus predicts the absence of an outcome?
This cannot be established simply by pairing a stimulus with no outcome, as that would just result in nolearning.
Extinction Treatment
in a conditioned inhibition paradigm, remove the reward when the stimulus is presented after it’s trained
Critique of learning theory:
Fails to address the complexity of human behaviour, and too heavily based on animal studies.
What is Behavioural Psychology?
Behaviour is learned• Individual difference in behaviour is the result of differentlearning experiences that people have had and thesituations in which they find themselves
Research definition of learning:
“A long lasting change in behaviour that results fromexperience”
Habituation is the simplest form of learning:
it is –learning NOT to respond to an unimportant event
Explain Pavlovian Conditioning
<img></img>
What does classical conditioning provide us with
a way to learn about cause-effect relations between environmental events
What are two important factors in classical conditioning
Sequence and Timing
Extinction
Present bell with no food following* ➜ reversal of conditioning process* ➜ extinction (association isundone)
Acquisition of new knowledge depends on
Intensity of US -> rapidness of learning Timing -> Optimal: Presentation of the CS occurs shortly before the US
Associative strength
The strength of the connection between internal representationsof the conditioned and unconditioned stimulus which determines the strength ofthe conditioned response (the Rescorla-Wagner model outlines this).
Associability /conditionability
Theease with which the strength of a conditioned response to a stimulus can beincreased by subsequent conditioning.
Error term
Difference betweenwhat you expected to happen and what actually happens
Contiguity
The temporal and spatial(time & space) relationship between events can influence the strength ofassociation. (arriving at the same time)
CS-UScontingency
Thedegree to which the US occurs during the presentation of the CS.
What are positive, negative and zero contingency?
- Positive: US is more likely present than the absent
- Negative: US is more likely absent than the present
- zero: US is equally likely during the presence and the absence of the CS.
Blocking
Kamin’s (1969) blocking effect study demonstrates thatconditioning to a stimulus could be blocked if the stimulus were reinforced incompound with a previously conditioned stimulus. A+, AB+, B+ = blocked conditioning of B
The summation principle
When the associative strength of individual stimuli are presentedtogether, the individual strengths are added together.
Cue competition
If two cues are trained in compound, they will compete for associative strength with the paired outcome, so that if we train AB+, the strength of association that develops between A and the outcome, will be weaker than the association between stimulus and outcome if we trained C+.
Overshadowing
The disruption of conditioning with one stimulus because of the presence of another stimulus. -> stronger conditioned stimulus will overshadow a weaker one
Conditioned compensatory response:
The body usually tries to maintain a state of homeostasis. When people use drugs, the body and brain learn to counteract the effects of the drug upon presentation of conditioned stimuli (cues, e.g. needle) and respond to produce physiological reactions that are opposite to that of the drug (see Siegal paper)
Acquisition
is demonstrated. At first, the word can by itself causes no special response. After repeated pairings of the word can and the water, the word by itself gradually becomes more likely to cause a CR.
Stimulus generalisation
occurs when words that sound like can (e.g., cam, ban, ran, cap) lead to a CR.
