Question
During an assessment with a new client, the BCBA observes the client engage in stereotypic behavior on several occasions. The client is observed rocking and swaying when he is excited and when presented with a new or more difficult task. Based on the information provided, how would the BCBA best define this behavior in observable and measurable terms?
- Stereotypic behavior is defined as rocking the upper body forward and backward in swaying motion while in a sitting position.
- Stereotypic behavior is defined as swaying the body when seemingly upset or excited.
- Stereotypic behavior is defined as anxiety-based behavior of swaying body back and forth when overwhelmed.
- Stereotypic behavior is defined as swaying approximately 4 times per hour.
Rationale
Step 1: Identify the concept being tested
This question tests your understanding of using observable and measurable terms to generate definitions of behavior.
Step 2: Analyze the question
In this scenario, a BCBA is conducting an assessment when they observe a stereotypic behavior. The BCBA needs to provide a definition that is both observable and able to be accurately measured.
The Correct Answer is A
Answer A provides a definition that is observable (rocking upper body forward and backward, while sitting) and enables accurate measurement. Answer A provides a parsimonious definition without including subjective information.
Incorrect Choices:
- This definition provides some observable information but does not include the specific topography of the behavior. Additionally, this definition includes an explanation of the behavior that is not observable.
- Although this definition provides some observable information, the definition also includes unconfirmed information (anxiety based). This would not be the best operational definition given the information provided.
- This definition provides some observable information but is very unclear on behavioral topography.
