1

Differential reinforcement

Process that consist of reinforcement and extinction that may result in either differentiation or discrimination

2

Two operations of differential reinforcement

Reinforcement
Extinction

3

Differentiation

Results when differential reinforcement consists of reinforcing one response while placing a second response on extinction

4

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

5

Simultaneous discrimination training

Both S^D and SΔ stimulus conditions are presented to the learner at the same time

6

Successive discrimination training

Only one antecedent (S^D and SΔ) is presented to the learner in a given trial

7

Discrimination training

Reinforce a response in the presence of a stimulus, but not in the absence of that stimulus

8

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

9

Components of a discrete trial

An antecedent stimulus that sets the occasion for the learner's response
A response by the learner
A teacher provided consequence for the learner's response

10

Model

An antecedent stimulus that evokes the imitative behavior

11

Planned models

Prearranged antecedent stimuli that facilitate new skills

12

Unplanned models

All antecedent stimuli with the capacity to evoke imitation

13

Imitation training

Teaching the learner to imitate or do exactly what the person providing the models is doing

14

Types of imitation

Fine motor
Gross motor
Object imitation

15

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

16

Listener responding

Following directions or complying with requests of others

17

Feature

The parts of items and descriptions of items

18

Function

The actions that typically go with the items or what one does with the items and classes

19

Class

The group(s) the items belong

20

Errorless teaching

Procedure in which the prompt is provided right away

21

Differential outcomes procedures

Different reinforcers are provided in a discrimination task each of which is correlated with a given stimulus

22

Differential outcomes can be effective in...

Difficult discrimination tasks

23

Discrete trial teaching

Antecedents are presented; teacher waits for the learner to respond, learner responds, and teacher provides consequence contingent on the learner's response

24

Components of a discrete trial

An antecedent stimulus that sets the occasion for the learner's response
A response by the learner
A teacher provided consequence for the learner's response

25

Task Interspersal

Programming mastered items or tasks in between acquisition trials during discrete trial instruction

26

Incidental teaching

One or more cues occur or motivating operations are captured in a naturally occurring situation. Naturally occurring consequences are delivered contingent on learner's response.

27

Capturing

Taking advantage of a teaching situation that arises without warning in the natural setting

28

Contriving

Setting up a pre-arranged teaching opportunity

29

DTT often results in ...

Rapid rate of acquisition

30

IT/NET often results in...

Stimulus generalization and induction

31

DRH

Differential reinforcement of high-rate behavior

32

Full session DRH

Engage in a minimum number of responses in a given time period

33

IRT DRH

Engage in one response within a certain period of time
