Whole-interval recording tends to do what to the duration of a behavior?

• A. Overestimate
• B. Accurately measure
• C. Underestimate
• D. Neglect measurement

Answer: (C)

Whole-interval recording is a time-sampling method that focuses on whether a behavior occurs during an entire specified interval of time. If the behavior occurs even once during that interval, it is recorded as "occurring," but if it does not occur for the entire duration of the interval, it is recorded as "not occurring." Because this method requires the behavior to persist through the entirety of the interval to be counted, it often misses instances where the behavior occurs in shorter bursts. As a result, whole-interval recording tends to underestimate the total duration of a behavior. This underestimation occurs because it does not account for partial occurrences that are shorter than the interval length, leading to a scenario where behaviors that do not happen consistently throughout the entire interval are not recorded. Therefore, when analyzing the data collected through whole-interval recording, one might find that the frequency or duration of the behavior appears less than it actually is in real-time, demonstrating underestimation of the behavior.
