Definitions:

Latency Recording

A variation of duration recording in which an observer records how long it takes a student to begin engaging in a behavior after the teacher instructs the student to perform it.

Interval Recording

A data collection method where the observation period is divided into intervals, and the presence or absence of behavior is recorded in each interval.

Counting Behavior

The process of systematically tallying instances of a specific behavior for the purpose of analysis or intervention.
