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?

  1. Stereotypic behavior is defined as rocking the upper body forward and backward in swaying motion while in a sitting position.
  2. Stereotypic behavior is defined as swaying the body when seemingly upset or excited.
  3. Stereotypic behavior is defined as anxiety-based behavior of swaying body back and forth when overwhelmed.
  4. 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:

  1. 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.
  2. 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.
  3. This definition provides some observable information but is very unclear on behavioral topography.
