Question 1

Dr.Soto was conducting research in a small rural community in Asia that was affected by an earthquake.Dr.Soto collected baseline measurements on posttraumatic responses and then the natural disaster assistance team arrived.Dr.Soto collected the same information again from respondents after the disaster assistance team had been stationed for one week.After two weeks the disaster assistance team left and Dr.Soto collected posttraumatic response data again.Dr.Soto expected that the posttraumatic responses would _____ after the disaster assistance team left.

Accepted Answer

Based on the information given, Dr. Soto conducted baseline measurements before the disaster assistance team arrived, which likely measured posttraumatic responses in the absence of outside intervention. Therefore, it is reasonable to expect that posttraumatic responses would return to baseline after the disaster assistance team left, since there would no longer be outside intervention to influence responses.

Question 2

Dr.Cross is implementing an A-B design.Which of the following scenarios best describes an A-B design?

Accepted Answer

An A-B design involves two phases: A (baseline) and B (intervention). In this scenario, option A correctly describes an A-B design where Dr. Cross first assesses baseline anxiety (A) and then introduces an intervention, video clips of baby animals (B), followed by a reassessment of anxiety.

Question 3

Dr.Soto was conducting research in a small rural community in Asia that was affected by an earthquake.Dr.Soto collected baseline measurements on posttraumatic responses and then the natural disaster assistance team arrived.Dr.Soto collected the same information again from respondents after the disaster assistance team had been stationed for one week.After two weeks the disaster assistance team left and Dr.Soto collected posttraumatic response data again.Dr.Soto expected that the posttraumatic responses would return to baseline after the disaster assistance team left.What is the dependent variable in this A-B design?

Accepted Answer

The dependent variable in this A-B design is the posttraumatic responses, as it is being measured and studied throughout the different stages of the study.

Question 4

Dr.Cross is implementing an A-B-A-B design.Which of the following scenarios best describes an A-B-A-B design?

Accepted Answer

An A-B-A-B design involves an initial baseline measurement (A), an intervention phase (B), a return to baseline (A), and a second intervention phase (B). Option D accurately describes this sequence by assessing anxiety, introducing an intervention (video clips of baby animals), removing the intervention, and then reintroducing the intervention, with assessments at each phase.

Question 5

Dr.Wakes decides to study one individual's responses to stressful situations.The participant will act as both control and experiment.The general term for this type of design is:

Accepted Answer

This is a single-subject design, where the individual acts as both control and experiment, and their responses are measured under different conditions.

Question 6

Dr.Cross is implementing an A-B-A design.Which of the following scenarios best describes an A-B-A design?

Accepted Answer

An A-B-A design involves the following steps:
A - baseline measurement
B - intervention
A - baseline measurement
So, in scenario C, Dr.Cross assesses baseline anxiety (A), introduces video clips of baby animals (B), reassesses anxiety (A), ceases the video clips of baby animals and reassesses anxiety again (second A). This follows the pattern of an A-B-A design.

Question 7

Newman is interested in using an A-B design for his thesis study examining behavioral interventions for emotion dysregulation.However,he makes an appointment with his mentor because he is confused as to what type of design an A-B study would be considered.Which of the following is the most appropriate description of an A-B design?

Accepted Answer

An A-B design is a within-subjects design where the baseline behavior is observed (A) and then an intervention is introduced (B) to observe any change in behavior.

Question 8

Dr.Marquez is lecturing to his class on single-subject designs.He noted that in an A-B design,the B phase represents the:

Accepted Answer

In an A-B design, the A phase represents the baseline measurement and the B phase represents the experimental treatment. Therefore the correct answer is A, experimental treatment.

Question 9

Dr.Soto was conducting research in a small rural community in Asia that was affected by an earthquake.Dr.Soto collected baseline measurements on posttraumatic responses and then the natural disaster assistance team arrived.Dr.Soto collected the same information again from respondents after the disaster assistance team had been stationed for one week.After two weeks the disaster assistance team left and Dr.Soto collected posttraumatic response data again.Dr.Soto expected that the posttraumatic responses would return to baseline after the disaster assistance team left.Dr.Soto is using what type of design?

Accepted Answer

Dr. Soto is using an A-B-A design, which involves collecting baseline data (A), introducing an intervention (B), and then withdrawing the intervention to see if the behavior returns to baseline (A). In this case, the intervention is the presence of the disaster assistance team.

Question 10

The NIH is taking proposals for a new research grant they are bestowing.The NIH is particularly interested in research proposals that use an A-B design.Which of the follow research designs would be most appropriate for the grant?

Accepted Answer

The answer of The NIH is taking proposals for a...

Question 11

Which of the following statements most accurately reflects an A-B-A design?

Accepted Answer

A-B-A designs involve measuring the same variable with the same participants during a baseline period (A), then an intervention period (B), and then returning to the baseline period (A) to measure the effects of the intervention.

Question 12

Dr.Marquez is lecturing to his class on single-subject designs.He noted that in an A-B design,the A phase represents the:

Accepted Answer

In an A-B design, the A phase represents the baseline measurement before the experimental treatment is implemented. This allows for comparison of the participant's behavior before and after the intervention.

Question 13

The NIH is taking proposals for a new research grant they are bestowing.The NIH is particularly interested in research proposals that use an A-B-A design.Which of the follow research designs would be most appropriate for the grant?

Accepted Answer

The A-B-A design involves measuring a behavior or outcome (A), then manipulating or introducing an intervention (B), and then measuring the behavior or outcome again (A). In this case, the behavior or outcome of interest is obsessive-compulsive symptoms, and the manipulation is touching a public toilet seat. Option C follows this design by measuring symptoms, introducing the intervention, and then measuring symptoms again before withdrawing the intervention. Options A and D introduce multiple interventions, which would complicate the analysis of the data. Option B only includes the intervention and does not measure symptoms before and after, which would not follow the A-B-A design.

Question 14

Dr.Nadine wants to establish a _____relationship,so she includes both a baseline measure and a postintervention measure.

Accepted Answer

Dr. Nadine's inclusion of both a baseline measure and a postintervention measure suggests that she is trying to establish a cause-and-effect relationship between the intervention and the outcome. By comparing the pre- and post-intervention measures, Dr. Nadine will be able to assess whether the intervention had any effect on the outcome of interest. This type of design is commonly used in experimental research, where researchers manipulate an independent variable (in this case, the intervention) to determine its effect on a dependent variable (the outcome).

Question 15

Which of the following statements most accurately reflects an A-B design?

Accepted Answer

A-B designs involve measuring the same variable twice with the same participant. The A phase serves as the baseline or control condition, while the B phase involves the introduction of the experimental manipulation. This design allows for clear evaluation of the effect of the manipulation on the measured variable.

Question 16

Dr.Garrod is explaining single-subject designs to his students and one student asks,"What is the control in a single-subject design?" What is the correct answer?

Accepted Answer

In a single-subject design, the participant serves as their own control. The intervention or treatment is usually applied during one phase of the study, and the participant's behavior is measured before and after the intervention/treatment. This allows for comparison within the individual over time.

Question 17

A single-subject design is a special type of _____using one participant or group to assess changes for that individual or group.

Accepted Answer

A single-subject design involves using one participant or group to assess changes for that individual or group. This is an example of within-subjects design where each participant serves as their own control. Therefore, option A is the correct choice.

Question 18

The NIH is taking proposals for a new research grant they are bestowing.The NIH is particularly interested in research proposals that use an A-B-A-B design.Which of the follow research designs would be most appropriate for the grant?

Accepted Answer

The answer of The NIH is taking proposals for a...

Question 19

In an A-B-A design,after removal of the intervention researchers are looking for _____;that is,whether the assessed levels of the dependent variable return to baseline after the intervention has been removed.

Accepted Answer

In an A-B-A design, the researcher removes the intervention to observe whether the dependent variable returns to baseline levels. This is known as a reversal in the effect. Therefore, the best choice is A.

Question 20

Which of the following statements most accurately reflects an A-B-A-B design?

Accepted Answer

A-B-A-B designs measure the same variables with the same participants. The design involves measuring a behavior (or dependent variable) during a baseline phase (A), introducing an intervention (B), removing the intervention to return to the baseline phase (A), and reintroducing the intervention again (B). This allows for comparison of the behavior in the presence and absence of the intervention and is often used in treatment evaluation research.
