| Term | Definition |
|---|---|
| Measurement | __________ is the process of assigning numbers and units to particular features of objects or events |
| Measurable Dimensions of Behavior | repeatability, temporal extent, temporal locus |
| Repeatability | instances of a response class can occur repeatedly through time (i.e., frequency of behavior) |
| Temporal Extent | every instance of behavior occurs during some amount of time (i.e., duration of behavior) |
| Temporal Locus | every instance of behavior occurs as a certain point in time with respect to other events (i.e., response latency and IRT) |
| Count | __________ is simply a tally of the # of occurrences of a behavior |
| Rate/Frequency | # of responses per unit of time |
| Free Operant | any operant that can be emitted at any time, are discrete, and can produce a wide range of response rates (SIB, stereotypy) |
| Discrete Trials | the rate of each discrete response is controlled by a given opportunity to emit the response |
| Celeration | __________ is a measure of how rates of response change over time |
| Standard Celeration Chart (SCC) | A chart that provides a standard format for displaying rate over time |
| Celeration Trend Line | A trend line drawn through a series of graphed data points, visually represents the direction and degree of trend in the data |
| Celeration Time Period | X-axis on celeration charts measuring time |
| Duration | __________, the amount of time in which a behavior occurs (basic measure of temporal extent; use when wanting to measure bxs that occur at very high rate grocer for extended periods of time) |
| Response Latency | __________, is a measurement of the elapsed time between the onset of a stimulus and the initiation of a subsequent response |
| Inter response Time (IRT) | __________, is the amount of time that passes between 2 consecutive instances of a response (longer the __________, the lower the rate of response) |
| Percentage | A ratio combining the same dimensional quantities (#/#; duration/duration; latency/latency) |
| Trials-To-Criterion | # of response opportunities needed for a person to achieve a pre-established level of accuracy of proficiency |
| Derivative Measures | percentage and trials-to-criterion are __________ |
| Topography | the physical forma or shape of a behavior |
| Magnitude | the force or intensity with which a response is emitted |
| Procedures for Measuring Behavior | Event recording, timing, and various time sampling methods |
| Event Recording | __________ encompasses a wide variety of procedures for detecting and recording the number of times a behavior occurs |
| Time Sampling | __________ involves dividing the observation period into time intervals and then recording the presence of absence of behavior within or at the end of each interval (e.g., whole/partial interval recording and momentary time sampling) |
| Whole-Interval Recording | with __________, the observer records whether a target behavior occurred throughout the entire interval (underestimates; provides information on duration per occurrence; use when measuring continuous or high rate behavhiors) |
| Partial-Interval Recording | with __________, the observer records whether the behavior occurred at any time during the interval (overestimates total duration & underestimates the rate of high frequency behavior) |
| Momentary Time Sampling | with __________, the observer records whether the target behavior is occurring at the moment that each interval ends (used to measure continuous behaviors) |
| Planned Activity Check | A variation of momentary time sampling that uses head counts to measure “group behavior” |
| Artifact | an __________ is something that appears to exist because of the way it is examined or measured |
| Measurement by Permanent Response Product | measuring behavior after it has occurred by measuring the effects that the behavior produced on the environment |
