Which recording method records the response if it occurs throughout the entire interval?

• A. Partial interval recording (PIR)
• B. Latency
• C. Percent occurrence
• D. Whole interval recording (WIR)

Answer: (D)

Whole interval recording keeps track only if the behavior is present for the entire interval. In each fixed time slice, you mark the interval as a win only when the response runs for the full duration of that interval; if the behavior starts, stops, or only lasts partway through, that interval isn’t recorded. This makes the method conservative and tends to underestimate how much the behavior actually occurs because brief or partial instances aren’t counted. By contrast, partial interval recording would flag any occurrence within the interval (often overestimating), latency measures how long after a cue the first response occurs, and percent occurrence looks at the proportion of intervals where the behavior happened at least once. So, the recording method that captures the response only if it happens across the entire interval is whole interval recording.
