In whole interval recording, how is behavior recorded?

In whole interval recording, behavior is documented only if it occurs for the entire duration of the specified interval. This method is particularly useful for measuring behaviors that are continuous and require a sustained demonstration to be considered present. By only recording instances where the behavior lasts the entire interval, this approach helps to focus on the duration and consistency of the behavior, rather than sporadic occurrences.

Using this method allows practitioners to capture a more comprehensive view of the behavior's persistence, which can be critical for behavior change plans where consistent engagement or participation is desired. For instance, if the behavior is supposed to be a sustained action, such as attending to a task, the whole interval recording captures the likelihood that the individual maintained that behavior throughout the entire observation period.
