PSYC332 Stimulus Equivalence

Stimulus Equivalence
A behavioural process to understanding semantics
Generalised Operants
Contingencies apply to the class of behaviours, not just the individual instance of a behaviour e.g. a person may be reinforced for not only a specific instance of imitating, but also the behaviour of imitating itself
Higher order classes of Behaviour
Contingencies may operate differently for the class of behaviour than for specific instances
Perceptual Concept
Dimensional, fuzzy class (natural category)
Functional Equivalence Class
Stimuli which serve the same function or engender the same response. If the function of one class member is altered, then the new function will transfer to other class members
(Stimulus-response relations)
Stimulus Equivalence Classes
Formally defined by reflexivity, symmetry and transivity between class members.
(Stimulus-stimulus relations)
Animals in Stimulus Equivalence
There is research to support that animals are capable of s.e. E.g. Yamamoto & Asano (1995) used Ai the chimp who had 7 years of language training.
Identity matching. A --> A.
e.g. *picture of apple* --> picture of applepicture of applepple* --> *picture of apple*
The relationship between A and B, and B and C.
e.g. picture of apple --> "apple" OR
"apple" --> WORD: apple
Relationship between A and C.
E.g. picture of apple --> WORD: apple
Emergent Behaviours
B --> A is emergence symmetry; C --> B is emergence transivity
