Lecture 10: Discrimination, Generalization and Fading

operation bhvr will always be influenced by

environment, such as ppl, places, onkectse, etc.

ABC assessment

Antecendent, events that happen before the bhvr, behaviour, consequences, events that happen after

stimulus discrimination

process by which we learn to emit a specific behaviour in the presence of some stimuli and not in the presence of others

stimulus control

degree of correlation between a stimulus and associated repose, good or effective stimulus control = high correlation

discriminative stimulus

response has been rf only in the presence of a particular stimulus, cue that a particular response will pay off

extinction stimulus

response has been extinguished only in the presence of a particular stimulus, cue that a particular response will not pay off

types of controlling stimulo

discriminative stimulus (for rf), extinction stimulus, also a stimulus can be a Sd for one behaviour and Es for another response at the same time

operation stimulus discrimination training

procedure of reinforcing a response in the presence of a SD and extinguishing that response in the presence of an ES, effects: stimulus discrimination, good stimulus control

stimulus generalization

opposite of SD, when a person responds the same way to a different stimulus.

unlearned stimulus generalization

due to considerable physical similarity, likely to perform a behaviours in a new situation if that situation is very similar to a situation when a behaviour was learned (e.g., you dont need to learn how to drive every car)

learned stimulus generalization involving minimal physical similarity,

when someone learns how to respond to a stimulus class or concept (e.g., once you learn about the class of birds, you can generalize that to a bunch of different birds)

conceptual behaviour

emitting appropriate behaviour to all members of a common-element stimulus class, but not those that don’t belong to the class

involving no physical similarity,

stimulus equivalence class: set of dissimilar stimuli which an individual has learned to group or match together or respond to in the same way (e.g., concept of food)

3 term contingency

As and Cs of B (e.g., Sd → response → Rf)

contingency shaped behaviour

developed through trial and error

rule governed behaviour

controlled by the statement of a rule. rule = situation in which a bhvr will lead to a consequence (3 term contingency)
