| Term | Definition |
|---|---|
| Whole-interval recording | A direct-observation method used to estimate how frequently behavior occurs. Observers record whether the behavior occurs throughout each in a series of contiguous intervals. |
| Reactivity | Behavior changes because the individual is aware that they are being watched. |
| Partial-interval recording | A direct-observation method used to estimate how frequently behavior occurs. Observers record whether the behavior occurs during any portion of each in a series of contiguous intervals. |
| Outcome recording | Recording the distinct, observable, lasting product(s) of behavior, instead of the behavior itself. |
| Magnitude | A dimension of behavior – the force or intensity of a behavior. |
| Latency | A dimension of behavior – the interval of time between the opportunity to respond and the response itself. |
| Interobserver agreement (IOA) | The extent to which two independent observers’ data are the same after having directly observed the same behavior at the same time. |
| Frequency | A dimension of behavior – the response count divided by time (response rate) or opportunity to respond. |
| Event recording | Each instance of behavior is recorded at the moment it occurs. |
| Duration recording | A direct-observation method used when measuring the latency or duration of a target behavior. |
| Duration | A dimension of behavior – the interval of time between the start and the end of the behavior. |
| Direct observation | When behavior is directly observed, the behavior is recorded as the behavior occurs, or a lasting product of the behavior is recorded at a later time. |
| Dependent variable | The dependent variable in a behavior-analytic experiment is the objectively measured target behavior. |
