Which term describes the proportion of observed opportunities in which the target behavior occurs?

• A. Percent occurrence
• B. Percent duration
• C. Latency
• D. Inter-response time (IRT)

Answer: (A)

This item tests understanding of measuring how often a behavior occurs across opportunities. Percent occurrence is the term for the proportion of observed opportunities in which the target behavior happens. It’s calculated by dividing the number of opportunities where the behavior occurred by the total number of opportunities, then multiplying by 100. For example, if there are 10 opportunities and the behavior appears in 7 of them, the percent occurrence is 70%. Percent duration would tell you how long the behavior lasts relative to the observation period, not how often it happens across opportunities. Latency is the time from a cue to the start of the behavior, and inter-response time is the time between successive occurrences of the behavior. These other measures describe different aspects of behavior timing and duration rather than the frequency across opportunities.
