A behavior analyst created a program to increase the amount of time a client spends jogging on a treadmill. The behavior analyst designed the program to include an increasing step-wise reinforcement criteria that increases in criterion based on current performance until reaching a terminal goal of 60 minutes. What type of experimental design did the behavior analyst use?
- Withdrawal Design
- Changing Criterion Design
- Multiple Probe Design
- Multiple Baseline Design
Step 1: Identify the concept being tested
This question tests your understanding of experimental design.
Step 2: Analyze the question
In this scenario, the analyst has created a program to increase time spent on a tread mill with a reinforcement criteria that increases in a step wise fashion based on the performance of the individual.
The Correct Answer is B
A changing criterion design is an experimental design in which an initial baseline phase is followed by a series of treatment phases consisting of successive and gradually changing criterion for reinforcement or punishment. Experimental control is evidenced by the extent to which the level of responding changes to conform to each new criterion.
- A Withdrawal design is also known as an A-B-A-B design. In this type of experimental design, a treatment condition is sequentially or partially withdrawn to demonstrate a functional relationship between the independent and dependent variable.
- A multiple probe design is a variation of the multiple baseline design. A multiple probe design features intermittent measurement, or probes, during baseline. It can be used to evaluate the effects of instruction on skill sequences in which it is unlikely that the subject will demonstrate improved performance on steps that occur later in the sequence before learning prior steps.
- A multiple baseline design can be conducted across subjects, settings, and behaviors. A multiple baseline design begins with the concurrent measurement of two or more behaviors in a baseline condition. In a multiple baseline across settings, baseline data is collected across all settings at the start of experimentation. When steady responding is achieved in baseline for each setting, the treatment is then applied in the first setting, and baseline remains in effect in the others. When significant behavior change is demonstrated after implementation of the treatment in the first setting, the researcher implements the treatment in the second setting. This process is then repeated in the third setting.
