What is the primary purpose of whole interval recording in behavior measurement?

Whole interval recording is a method used in behavior analysis to assess whether a specific behavior occurred throughout an entire designated time interval. This approach is particularly useful for capturing behaviors that are continuous or that can be sustained over a period of time.

When utilizing whole interval recording, an observer notes whether the target behavior was present for the entirety of the observation period. If the behavior occurred for the entire interval, it is recorded as a "yes;" if it did not occur for the entire duration, it is recorded as a "no." This method provides information about the duration of the behavior rather than simply its frequency or momentary occurrence.

The focus on whether the behavior persists throughout the interval distinguishes whole interval recording from methods that simply count occurrences or measure durations in a different way. In contrast to techniques that quantify frequency or timing, whole interval recording emphasizes the continuity of the behavior within the set time frames, making it particularly valuable for understanding behavior patterns in various educational and therapeutic settings.
