A BCBA wants to measure the duration of a client's tantrum behavior. Which data collection method is most appropriate?
Answer: Duration recording
Duration recording measures the total time a behavior occurs from onset to offset, making it ideal for tantrum behavior.
When conducting a structured ABC observation, which component represents the antecedent?
Answer: The event or stimulus that precedes the behavior
The antecedent is the environmental event or stimulus that occurs immediately before the target behavior.
Which reliability measure is most appropriate when evaluating interobserver agreement for duration data?
Answer: Duration IOA (smaller/larger ratio)
Duration IOA calculates agreement by dividing the smaller duration by the larger duration for each observation period.
A behavior analyst uses 10-second partial interval recording. Which of the following is true about this method?
Answer: It tends to overestimate the true frequency of behavior
Partial interval recording scores an interval as positive if the behavior occurs at any point, which tends to overestimate the actual prevalence.
A clinician tracks how long it takes a child to begin a task after an instruction is given. This measurement is called:
Answer: Latency
Latency measures the time elapsed between the onset of a stimulus (instruction) and the initiation of the target behavior.
Which type of assessment involves presenting items or activities and observing a learner's approach, interaction, and avoidance to identify potential reinforcers?
Answer: Stimulus preference assessment
A stimulus preference assessment systematically evaluates an individual's preference for various stimuli to identify potential reinforcers.
During a functional behavior assessment, the BCBA reviews school records, interviews teachers, and observes the student in class without manipulation. This approach is known as:
Answer: Descriptive assessment
Descriptive assessment collects information through indirect methods (records, interviews) and direct naturalistic observation without experimental manipulation.
