| Term | Definition |
|---|
| artifact | an outcome or result that appears to exist because of the way it is measured but in fct does not correspond to what actually occurred |
| celeration | the change (acceleration or deceleration) in rate of responding over time |
| celeration time period | a unit of time (e.g., per week, per month) in which celeration is plotted on a Standard Celeration Chart |
| celeration trend line | this is measured as a factor by which rate multiplies or divides across the celeration time periods |
| count | a simple tally of the number of occurrences of a behavior |
| discrete trial | any operant whose response rate is controlled by a given opportunity to emit the response |
| duration | a measure of the total extent of time in which a behavior occurs |
| event recording | measurement procedure for obtaining a tally or count of the number of times a behavior occurs |
| free operant | any operant behavior that results in minimal displacement of the participant in time and space |
| frequency | a ratio of count per observation time |
| interresponse time (IRT) | the elapsed time between two successive responses |
| magnitude | the force or intensity with which a response is emitted |
| measurement by permanent product | a method of measureing behavior after it has occurred by recording the effects that the behavior produced on the environment |
| momentary time sampling | a measurement method in which the presence or absence of behaviors are recorded at precisely specified time intervals |
| partial-interval recording | a time sampling method in which the observer records whether the target behavior occurred at any time during the interval |
| percentage | a ratio formed by combining the same dimensional quantities |
| planned activity check (PLACHECK) | a variation of momentary time sampling in which the observer records whether each person in a group is engaged in the target behavior at specific points in time; provides a measure of "group behavior" |
| rate | a ratio of count per observation time |
| repeatability | refers to the fact that a behavior can occur repeatedly through time |
| response latency | the elapsed time from the onset of a stimulus (e.g., task direction, cue) to the initiation of a response |
| temporal extent | refers tot he fact that every instance of behavior occurs during some amount of time |
| temporal locus | refers to the fact that every instance of behavior occurs at a certain point in time with respect to other events |
| time sampling | a measurement of the presence or absence of behavior within specific time intervals |
| topography | the physical form or shape of a behavior |
| trials-to-criterion | a special form of event recording; a measure of the number of responses or practice opportunites needed for a person to achieve a preestablished level of accuracy or proficiency |
| whole-interval recording | a time-sampling method in which the observer records whether the target behavior occurred throughout the entire interval |
| repeatability, temporal extent, temporal locus | the three fundamental properties, or dimensional quantities, that behavior analysts can measure |
| observation period | this should always be noted when reporting count measures |
| free operant | can be emitted at nearly any time; is discrete, it requires minimal time for completion, and it can produce a wide range of response rates |
| interresponse time and response latency | 2 measures of temporal locus |
| time sampling | a method of measurement that is most useful with continuous and high-rate behaviors |
