What is the measurement method that records the presence or absence of behaviors at precisely specified time intervals?

The measurement method that records the presence or absence of behaviors at precisely specified time intervals is known as Momentary Time Sampling. This approach involves observing whether a specific behavior occurs at designated moments during an observation period. For example, an observer might check for the occurrence of a behavior at the end of every minute, providing a snapshot of whether the behavior was happening at that exact moment.

This method is particularly useful because it allows for efficient data collection without the need to continuously monitor the behavior for the entire time period. By focusing on specific intervals, it reduces the observer's workload while still providing valuable data on the frequency or occurrence of the behavior. In settings like classrooms, it helps in evaluating behaviors without interrupting the flow of activities.

Other measurement methods, such as Continuous Recording, involve tracking every instance of a behavior throughout the entire observation period, making it more comprehensive but also more demanding in terms of attention and time. Event Sampling focuses on specific events or occurrences of behaviors over a set period, which differs from the time-focused approach of Momentary Time Sampling. Partial Interval Recording measures whether a behavior occurs during specified intervals but does not capture the behavior's presence at specific moments like Momentary Time Sampling does. Thus, the precision and strategic timing of Momentary Time
