Stimulus Equivalence
Fichas del conjunto (14)
- 1Stimulus Equivalence originsWe often react to words and other symbols as if they are the things to which they refer. Linguistics forms as equivalent to their referents.
- 2High order classes of behaviours (all Generalised operants)Rule governed, observational learning, categorisation, stimulus equivalence, and concept formation
- 3Why are they Generalised Operant learning?Contingencies apply to the class of behaviours, not just the individual instances of behaviour. E.g., reinforcing imitation in general
- 4How might contingencies operate differently for the class of behaviours than for specific members?It is resistant to changes in reinforcement of individual members. As in extinction.
- 5Functional Equivalence ClassesAre categories of ARBITRARY stimuli that control the same function, e.g., stop signs, stop words, a hand signalling stop and a red light
- 6Vaughan used a procedure to alter the function of one member and this provided evidence for what?By teaching pigeons individual relationships for arbitrary signs, e.g. triangle, square mean go or is S+, while the others mean stop or S-. Then reverse the functions. Triangles now mean S- and visa versa. The pigeons learnt this in one trial and it provided evidence for functional equivalence classes.
- 7Stimulus EquivalenceAn individual learns to respond to all stimuli in a set as if they are interchangeable
- 8Do all relations in stimulus equivalence need to be taught?Only relations A -> B and B -> C need to be taught. Then emergent symmetry will create relations between B -> A, C -> B, and A <->C
- 9The test these emergent behaviours or relations how?They will teach the A -> B and B -> C relations then will provide the stimulus C and give options including A and A will always be chosen. Thus evidence of a learnt relation
- 10Stimulus Equivalence classes are formally defined byreflexivity, symmetry, & transitivity between class members. (emergent behaviours)
- 11Reflexivity isIdentity matching. A penguin is a Penguin. A <-> A
- 12Symmetry (emergent)Teach A -> B (A-penguin is B-"penguin") Then emergent symmetry means that B is also A
- 13Transitive relationA -> C will emerge. A-penguin B-"penguin" and C [Penguin]
- 14Adding in a new C -> D relation will alsoAdd A,B,C ->D relations
