D.9 Apply single-case experimental designs - Part - 2Acquisition

In a changing criterion design,

(all of the above) each phase must be long enough to establish stable responding. the length of each phase should vary. behaviors that are slower to change require longer phases.

With a multiple baseline design, demonstration of experimental control requires

(all of the above) staggered implementation of the intervention. a behavior change only with the onset of the intervention a replication of behavior change across at least two behaviors, persons, or settings.

Researchers plan to study exercise duration. They are collecting baseline measures of exercise duration. What must they do at this point if they are planning to use a changing criterion design?

Continue to collect baseline measures until exercise duration is stable.

The researcher collected baseline measures of exercise duration until measures were stable. What is the next step to implement a changing criterion design?

Implement a procedure that requires a slightly higher exercise duration for reinforcement of recording exercise duration than the average during baseline.

With a multiple baseline design, demonstration of experimental control requires

a change in behavior with onset of the intervention.

When using a multiple baseline across behavior design,

achieve stable responding for all target behaviors before intervening, if possible.

A multiple baseline design could be implemented across

behaviors, individuals, settings.

"A functional relation is demonstrated when rate changes correspond to the requirements of the contingencies" characterized with design?

changing criterion

An experimental design that, across phases, systematically varies the level of responding that is required to produce reinforcement or punishment is the

changing criterion design.

The researcher collected baseline measures of exercise duration until measures were stable and then implemented a procedure that required a slightly higher exercise duration for reinforcement than the baseline average. What must they do at this point if they are using a changing criterion design?

continue to collect intervention measures until they are stable.

In a changing criterion design,

each phase must be long enough to establish stable responding.

When using a multiple baseline across behaviors design,

intervene on the next behavior when the previous behavior is stable.

Using the same intervention, you intervene sequentially on the aggression, cursing, and spitting of a student. This describes a

multiple baseline across behaviors design.

You intervene sequentially in the classroom, cafeteria, and bus. This describes a

multiple baseline across settings design.

In a changing criterion design, experimental control is demonstrated when

performance approximates the requirement specified in the contingency as the criterion is varied.

In a changing criterion design, a larger magnitude change

provides more evidence of experimental control that a small change.

Which experimental conditions can be found in a changing criterion design?

reinforcement contingent upon 10 responses per minute, 20 responses per minute, then 30 responses per minute

When using a multiple baseline across behaviors design,

use one intervention across three behaviors that are not part of the same response class.
