| Term | Definition |
|---|---|
| antecendent stimulus class | set of stimuli that share a common relationship evoke same operation response classes or elicit same respondent behaviour |
| arbitrary stimulus class | evoke same response, do not share same physical form or relation i.e. vegetables |
| concept formation | behvioural outcome of stimulus generalization and discrimination |
| discriminative stimulus | increases momentary frequency of behaviour, stimulus in presence of which response has been reinforced. history of response not reinforced |
| feature stimulus class | share common physical forms(topographical or common relations(spatial) i.e. dog same breed all different |
| matching-to-sample | aba analysts to create equivalence among arbitrary stimuli |
| reflexivity | absence of training and reinforcement a response will select stimulus that matches self i.e. shown pic of bike, 3 other pics out chooses correct pic to bike to match |
| stimulus control | occurs (rate, latencey, duration, or aptitude) is altered in presence of antecedent stimulus, high probability that the behaviour will occur when a specific stimulus is presented |
| stimulus delta | stimulus in present, in past no reinforcement |
| stimulus discrimination training | 1 behaviour 2 antecedent stimulus conditions, response reinforced in presence of 1 sd but not reinforced in other sd (s delta) in time increase in correct sd and less in s-delta |
| stimulus equivalence | emergence of accurate responding to untrained non reinforced stimulus stimulus 3 things present to meet definition(reflexivity, symmetry, transitivity) |
| stimulus generalization | antecedent stimulus history evoke response has been reinforced in presence, similar type behaviour, similar stimuli share similar physical properties |
| stimulus generalization gradient | graphically depicts, (stimulus generalization, discrimination)extent to which responses reinforced in one stimulus condition are emitred in presence of untrained stimuli |
| symmetry | reversibility of the sample stimulus and comparison i.e. bike is said pictures are shown, kid pics correct one |
| transitivity | training of other two stimuli (symmetry and reflexivity) transitivity emerges without additional instruction i.e. written word bike matches spoken word |
