A direct and descriptive measurement and assessment procedure in which instances of a naturally occurring target behavior and the specific environmental events (antecedents and consequences) accompanying the behavior are recorded. Measurement is conducted using checklists to mark occurrences and nonoccurrences of the target behavior during a specified time interval and to calculate the conditional probabilities for that behavior.
