Discrete Trial Instruction

Question 1

Discrete trials

Answer 1

A small highly structured unit of instruction consisting of a short instruction, a response from a learner, and feedback tied to the response

Question 2

Discrete trial instruction

Answer 2

A highly structured intervention based on specific and individualized goals, composed of many discrete trials and commonly used in ABA intervention for children with autism

Question 3

Early Intensive Behavior Intervention, or EIBI

Answer 3

An intensive program consisting of discrete trials and other ABA-based strategies delivered for up to 40 hours a week

Question 4

Operant conditioning

Answer 4

A process where individuals learn to behave in ways to get reinforcers and avoid punishers

Question 5

Discriminative stimulus

Answer 5

Instruction in a discrete trial; exerts control over behavior because the behavior was reliably reinforced in the presence of that stimulus in the past

Question 6

Response

Answer 6

What an individual does after a discriminative stimulus; a behavior that occurs when certain conditions are present

Question 7

Consequence

Answer 7

An event that occurs after a response that increases it in the future if it is a reinforcer or decreases it in the future if it is a punisher; in a discrete trial it is a reinforcer or a corrective prompt

Question 8

Prompt

Answer 8

A type of assistance that increases the chances a learner will provide a correct response

Question 9

Motivating operation

Answer 9

Variables that affect the value of a reinforcer to a learner

Question 10

Inter-trial interval

Answer 10

The time between the end of one discrete trial and the beginning of the next one; the time is best spent with the client engaging with the reinforcer and the RBT entering data on the previous trial

Question 11

Prompt fading

Answer 11

Reducing or removing prompts given with an SD to allow the client to respond correctly and independently

Question 12

Session momentum

Answer 12

Rapid pace of discrete trial delivery

Question 13

Least to most prompting

Answer 13

A system that gradually increases the intrusiveness of prompts necessary to get a client to give a correct response

Question 14

Errorless learning

Answer 14

An approach to DTI based on the idea that learning will be more efficient if the time between an SD and a correct response is as short as possible; when an instructor prompts a correct response from a learner before they have a chance to select an incorrect one and then provides reinforcement for correct responding

Question 15

Preference assessment

Answer 15

Procedures used to determine which items are preferred by the learner in order to determine which are likely to work as positive reinforcers

Question 16

Skill acquisition plans

Answer 16

Individualized plans for learners that provide goals and the procedures necessary to teach the skills associated with each goal

Question 17

Massed trials

Answer 17

A form of a discrete trial intervention where the same target is presented over and over again

Question 18

Random rotation of trials

Answer 18

A form of discrete trial intervention mixing previously mastered trials along with the newly introduced trials

Question 19

Mand

Answer 19

A verbal operant that is a request

Question 20

Tact

Answer 20

A verbal operant that is a label or comment

Question 21

Intraverbal

Answer 21

A verbal operant that is a response to a verbal stimulus

Question 22

Echoic

Answer 22

A verbal operant that is present when a person repeats what another person says

Question 23

Probe

Answer 23

A trial or trials to test whether or not a client can respond independently to an SD

Question 24

Fluency

Answer 24

The combination of accuracy plus speed

Question 25

Stimulus generalization

Answer 25

When a response that was previously conditioned by one stimulus can be evoked by a different stimulus

Question 26

Stimulus fading

Answer 26

Gradually decreasing the intensity of a physical dimension of a stimulus that controls a response

Question 27

Naturalistic intervention

Answer 27

Principles of ABA applied to the daily routines or activities of a client to improve skills or decrease problem behaviors
