Answer
  • Reversal Design
  • Sequential Withdrawal Design
  • Removal Design

Question 5

Question
Multiple baseline design graphs measures all of the following EXCEPT:
Answer
  • settings
  • behaviors
  • people
  • interventions

Question 6

Question
Which type of graph is used MOST widely?
Answer
  • Multiple design
  • single subject
  • alternative treatments
  • scatterplot

Question 7

Question
Which highly flexible graph has a staggered step-like fashion display?
Answer
  • multiple stepline
  • multiple baseline
  • changing criterion design
  • alternating treatments with baseline and final phase

Question 8

Question
Multiple baseline across behaviors is where two or more different behaviors on the same subject and the subject acts as his/her own control.
Answer
  • True
  • False

Question 9

Question
Which type of multiple baseline is most widely used?
Answer
  • subjects/people
  • settings
  • behavior
  • interventions

Question 10

Question
Check the other variations of multiple baseline designs:
Answer
  • multiple acquisitions
  • multiple probe
  • delayed multiple baseline

Question 11

Question
Check the guidelines to follow when using multiple baseline designs.
Answer
  • select independent yet functionally similar baselines
  • permission has to be granted to use a multiple baseline design
  • caution must be given to how soon an intervention is applied
  • intervene on the most stable baseline first
  • do a reversal to as soon as possible
  • vary the lengths of the baselines

Question 12

Question
All of the following are advantages to using a multiple baseline design EXCEPT:
Answer
  • successful interventions do not have to be removed
  • easy to implement
  • evaluates generalization easily
  • demonstrates experimental control

Question 13

Question
Which are disadvantages to using the multiple baseline design?
Answer
  • Can not be used in various settings
  • subjects have to be similar in age
  • does not show experimental control
  • intervention may be delayed when otherwise doesn't need to be

Question 14

Question
Check which designs are experimental designs.
Answer
  • withdrawal
  • multiple baseline
  • scatterplot
  • reversal
  • functional baseline
  • changing criterion
  • alternating treatments

Question 15

Question
Changing criterion designs requires all of these considerations EXCEPT
Answer
  • length of phases
  • magnitude of criterion changes
  • number of criterion changes
  • when to apply the reversal

Question 16

Question
Examples of when to use a changing criterion design include:
Answer
  • math problems
  • reading fluency speed
  • distance running
  • head banging

Question 17

Question
Advantages to the changing criterion design include:
Answer
  • does not require reversal
  • gradually improves behavior and works well in classrooms
  • behaviors can be reversed
  • does not need to be repertoire
  • helps shape behaviors

Question 18

Question
Any experimental design in which the researcher reverses back to a previous condition is called
Answer
  • Reversal
  • withdrawal
  • multiple baseline
  • changing criteria
  • alternative treatment

Question 19

Question
The more preferred method of a reversal design is A-B-A over A-B-A-B.
Answer
  • True
  • False

Question 20

Question
The A-B-A-B reversal is the most straight forward and generally most powerful within-subject design for demonstrating a functional relationship between an environment manipulation and a behavior.
Answer
  • True
  • False

Question 21

Question
Reversal design includes what?
Answer
  • solid data points for actual measures of behavior and open data points for predicted data
  • open data points for actual measures of behavior and solid data points for predicted data

Question 22

Question
Experiments that use the reversal design to compare two or more treatment effects are vulnerable to confounding effects by sequence effects.
Answer
  • True
  • False

Question 23

Question
Which experimental design in which 2 or more conditions are presented in rapidly alternating succession independent of the level of responding & the differential effects on the target behavior are noted?
Answer
  • alternating intervention design
  • alternating treatment design
  • alternative treatments design

Question 24

Question
What type of experimental design would be best used when trying to determine which treatment is most effective?
Answer
  • alternating treatment design
  • parametric analysis
  • changing criterion design
  • multiple baseline design

Question 25

Question
What problems are avoided when choosing to use an alternating treatment design?
Answer
  • does not require treatment withdrawal
  • open- ended design
  • quickly compares different treatments
  • is limitless on how many treatments can be implemented at once
  • minimizes irreversibility
  • minimizes sequence effects
  • can be used with unstable data patterns
  • assess generalization of effects
  • interventions can begin immediately
  • never have to settle on just one treatment

Question 26

Question
Withdrawal and reversal designs are the same type of experimental design where the intervention is removed and a return to baseline has occurred. Withdrawal design will often be the technical term when looking for generalization of a behavior as the intervention is sequentially or partially withdrawn.
Answer
  • True
  • False
