Duration Per Occurrence

A type of duration recording that involves recording the length of time per episode that a student engages in a target behavior.

Average Duration

A type of duration recording that produces only one number to graph. In this approach, the durations of each episode of a target behavior are added together and divided into the total number of times the behavior occurred.

Dead Man's Test

A principle in behavior analysis suggesting that if a dead man can do it, it’s not behavior; emphasizing the importance of observable and measurable actions.

Stranger Test
