Throughout the entire interval. In interval recording, the entire observation window is split up into blocks of time. Whole-interval recording Definition A time sampling method for measuring behavior in which the observation period is divided into a series of brief time intervals Learn vocabulary, terms, and more with flashcards, games, and other study tools. This type of recording often underestimates rates of behavior. With whole interval recording you record the presence of the behavior only if it occurred for the entire duration of the interval. Start studying Whole vs. Interval recording documents whether a behavior occurred during a particular period. Then the clinician observes whether or not a behavior occurs during that time frame. Partial Interval Recording. There are two types of interval recording: whole interval (an observer indicates whether the behavior occurred during the entire time) and partial interval (an observer indicates whether the behavior occurred at any point during the time interval). This underestimates behavior. A momentary time sample (MTS) does not require continuous observation. A type of discontinuous measurement where you only mark that a behavior occurs during an interval if it occurs for the entire interval. For whole interval recording, the behavior must occur for the entire interval in order to be recorded as having occured, indicated by a (+). Pennypacker's Pedants presents:Whole interval recording is defined and semi critiqued. observation period. When using partial-interval recording, your data are more likely to overestimate the actual rate or duration of the target bx when measuring. Low-frequency behavior. With whole interval recording, you record the behavior of it occurs. Whole Interval Recording If Kim is interested in observing whether the children read for the entire fifteen-minute interval, then she would use the whole interval recording. In partial interval recording the target behavior is recorded if it occurs at any point during the interval (Green et al., 1982). There are a few variations on interval recording like whole-interval and partial-interval. Download the App Whole Interval Recording - When interval ends, mark if behavior exhibited for the entire interval - Underestimates behaviors - Requires undivided attention - Useful for ongoing behaviors that will continue across intervals Partial Interval Recording - Mark if behavior exhibited at any time during the interval - May overestimate behaviors Interval recording is a widely used method and two common types are partial interval recording and whole interval recording (Taylor et al., 2012). With partial interval recording you record the presence of the behavior if it occurred for any part of the interval. In that case, interval recording can be a massive asset. Whole Interval Recording.
