Skill Acquisition Procedures: Differential Reinforcement, DTT, & IT
Differential Reinforcement
Process that consists of reinforcement and extinction that may result in either differentiation or discrimination
Two Operations of Differential Reinforcement
1) Reinforcement 2) Extinction
Differentiation HINT: diffeRenTion=Response Topography
Results when differential reinforcement consists of reinforcing one response while placing a second response on extinction HOW TO RESPOND!
Discrimination HINT: diSCrimination = preSCence
Results when differential reinforcement consists of reinforcing a response when a certain stimuli is present and not reinforcing the same response when those stimuli are not present WHEN TO RESPOND!
Simultaneous Discrimination Training
Both the Sd and the S-delta stimulus conditions are presented to the learner at the same time.
Successive Discrimination Training
Only one antecedent (Sd or S-delta) 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.
What does 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 model is doing.
What are the 3 types of Imitation?
1) Fine motor 2) Gross motor 3) 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 response that is relatively infrequent.
