Which time sampling method records whether the target behavior occurred at any time during the interval?

• A. Whole Interval Recording
• B. Momentary Time Sampling
• C. Permanent Product Measurement
• D. Partial Interval Recording

Answer: (D)

Partial Interval Recording records whether the target behavior occurred at any point during the interval. If the behavior happens even briefly, it’s counted for that interval. This makes it useful for capturing whether the behavior tends to occur at all within blocks of time, though it can overestimate how often the behavior truly occurs because brief moments are treated the same as longer episodes. In contrast, Whole Interval Recording only counts the behavior if it happens for the entire interval, which tends to underestimate frequency; Momentary Time Sampling checks whether the behavior is happening at a specific moment (often at the end of the interval), which can miss occurrences in between; Permanent Product Measurement looks at the tangible outcome of the behavior rather than its occurrence within time intervals.
