Response duration

The total amount of time that a behavior occurs continuously.

Speed (in behavior measurement)

The length of time taken for a behavior to occur from start to finish.

Latency

The time that passes before a behavior begins.

Interval recording

A method of measuring behavior by recording occurrences during specified intervals of time.

Time sample recording

A form of interval recording that takes measurements at irregular intervals to avoid continuous observation.

Behavioral topography

The physical form or shape of a behavior, including the manner in which it is performed.

Number of errors

A measurement of how many times incorrect responses occur during a task.

Inter-observer reliability
