D05 Use Single-Subject Experimental Designs Part 7

Question 1

The results of an evaluation of two different interventions using an alternating treatments design show a large vertical distance between the data paths. This indicates that

Answer 1

One treatment was more effective than the other

Question 2

You are evaluating the efficacy of an intervention to help the members of a little league baseball team improve their throwing accuracy. The intervention, to be implemented over the of the baseball season, takes place during brief training sessions at the beginning of every team practice. Your evaluation is at risk of a confound due to

Answer 2

Maturation

Question 3

Which design could provide the most valid non-intervention measure with a demonstration of experimental control?

Answer 3

ABAB

Question 4

An advantage of the alternating treatments design over the reversal design is that

Answer 4

Differential effects of interventions are apparent despite practice effects.

Question 5

You want to use a multiple baseline across subjects design to evaluate the effect of extinction on SIB. Before beginning,

Answer 5

Determine how you will keep the subjects safe

Question 6

Under what circumstances would you consider using a BAB design?

Answer 6

When the target behavior could cause injury to the client or others

Question 7

An advantage of the alternating treatments design over the reversal design is that you can

Answer 7

Quickly identify the most effective treatment.

Question 8

After completing baseline and three sessions of the experimental phase, your client moves to another state. This exemplifies an experimental confound due to

Answer 8

Client attrition

Question 9

Continuing an experimental condition until staffing patterns stabilize is a strategy for avoiding a confound due to

Answer 9

Changes in the environment

Question 10

Under which circumstances is it inappropriate to use a reversal design?

Answer 10

All the above:
When the change in behavior produced by the intervention is irreversible.
When conducting a reversal is objectionable to the treatment team.
When withdrawing the intervention would risk injury to the client or staff

Question 11

An advantage of the alternating treatments design over the ABAB reversal design is that

Answer 11

Treatment of the problem behavior can begin right away

Question 12

An ethical consideration when using a withdrawal design to evaluate SIB is the

Answer 12

Risk of injury during the reversal phase

Question 13

Objections to using reversal designs to evaluate interventions for academic goals include

Answer 13

Concern that treatment gains won’t be recaptured after the reversal

Question 14

An advantage of the alternating treatments design over the reversal design is that

Answer 14

All the above:
The ethical dilemma of withdrawing an effective intervention is avoided.
Treatment of the problem behavior can begin right away.
You can quickly identify the most effective treatment.

Question 15

Under what circumstances would you consider using a BAB design?

Answer 15

All the above:
When time is limited.
When an intervention is already in place.
When the target behavior could cause injury to the client or others.

Question 16

One risk to the demonstration of experimental control when using a BAB design is that the behavior

Answer 16

Doesn’t deteriorate during the A condition

Question 17

A client may receive treatment for an ear infection as you are about to begin an intervention. To be able to experimentally evaluate the intervention, you should

Answer 17

Encourage the doctor to begin treatment and extend your baseline

Question 18

You need to intervene on a tolerable, but annoying behavior. What experimental design should you use?

Answer 18

ABAB

Question 19

A student stops working for candy in school because his mother has started putting candy in his lunch. This is a confound to

Answer 19

Bootleg reinforcement

Question 20

The day you are to begin an experimental reading intervention, the student becomes ill and is out for a week. When he returns, you should

Answer 20

Extend your baseline

Question 21

After less restrictive attempts have failed, you develop an intervention that includes an aversive component. You should always

Answer 21

Determine whether the program will be properly implemented.

Question 22

Under which circumstances is it inappropriate to use a reversal design?

Answer 22

When withdrawal of the intervention would risk injury to the client or staff.

Question 23

Under which circumstances is it inappropriate to use a reversal design?

Answer 23

When the change in behavior produced by the intervention is irreversible

Question 24

Beginning an experiment with more subjects than you need is a strategy for avoiding a confound due to

Answer 24

Client attrition

Question 25

Rapidly changing experimental conditions is a strategy for avoiding a confound due to

Answer 25

Maturation

Question 26

An ethical consideration when using a multiple baseline design to evaluate SIB is the

Answer 26

Extended baseline for self-injury

Question 27

You are evaluating the effects of a new token economy in a special education classroom. To save money, instead of using objects as tokens, teachers are directed to deliver tokens by tallying the number of token earned per lesson on a data sheet kept on the student’s desk. Your evaluation is at risk of a confound due to

Answer 27

Bootleg reinforcement
