Unit 2 Flashcards
Differential reinforcement
Process that consist of reinforcement and extinction that may result in either differentiation or discrimination.
Two operations of differential reinforcement
Reinforcement
Extinction
Differentiation
Results when differential reinforcement consists of reinforcing one response while placing a second response on extinction.
Discrimination
Results when differential reinforcement consists of reinforcing a response when certain stimuli are present and not reinforcing the same response when those stimuli are not present.
Simultaneous discrimination training
Both the SD and SΔ stimulus conditions are presented to the learner at the same time.
Successive discrimination training
Only one antecedent (SD or SΔ) is presented to the learner in a given trial.
Discrimination training
Reinforce a response in the presence of a stimulus, but not in the absence of that stimulus.
Stimulus control
A situation in which the frequency, latency, duration, or amplitude of a behavior is altered by the presence or absence of an antecedent stimulus.
Discrimination training results in:
Stimulus control
Model
An antecedent stimulus that evokes the imitative behavior
Planned models
Prearranged antecedent stimuli that facilitate new skills
Unplanned models
All antecedent stimuli with the capacity to evoke imitation
Imitation training
Teaching the learner to imitate or do exactly what the person providing the models is doing
Types of imitation
Fine motor
Gross motor
Object imitation
High probability request sequence
An antecedent manipulation in which 2-5 easy/known tasks are presented in quick succession immediately prior to a difficult/ high effort task or a response that is relatively infrequent
