BACB Behavior Change Procedures 3

Question 1

In a discrete trial teaching (DTT) format, what is the role of the 'intertrial interval' (ITI)?

Accepted Answer

The brief pause between the end of one trial and the start of the next

Answer

The intertrial interval (ITI) is the brief period of time between the end of one discrete trial and the beginning of the next, helping to demarcate trials clearly.

Question 2

Which naturalistic teaching strategy captures the learner's motivation in the natural environment to teach communication and other skills?

Accepted Answer

Incidental teaching

Answer

Incidental teaching uses naturally occurring opportunities when the learner initiates interaction, capitalizing on existing motivation to promote generalized skill use.

Question 3

What does 'stimulus fading' involve in a prompting hierarchy?

Accepted Answer

Gradually changing the physical dimension of a stimulus prompt until the natural SD controls the response

Answer

Stimulus fading systematically changes the physical properties (size, color, intensity) of a stimulus prompt until the unaltered natural SD evokes the correct response.

Question 4

Which maintenance strategy involves periodically re-exposing a learner to learned material to prevent skill decay?

Accepted Answer

Booster sessions

Answer

Booster sessions are periodic brief review sessions that re-expose learners to previously mastered skills to maintain performance over time.

Question 5

Which procedure involves mixing mastered tasks with acquisition tasks to increase motivation and reduce errors?

Accepted Answer

Interspersal of known and unknown items

Answer

Interspersal training intermixes easy, already mastered items with new harder items, increasing reinforcement density and reducing frustration during instruction.
