What is measurement? applying quantitative labels to observed properties of events using standard set of rules
Why do we need measurement? To see if behaviors are worsening or improving; To see the effects of intervention before, during and after treatment; Help you decide whether treatment needs to be changes; Helps you stop treatment that may be ineffective
What are the benefits of measurement? It makes treatment effective, it helps you verify that the treatment is going well
What are the three fundamental properties of behavior? Repeat ability or count-ability: behavior can be counted
Temporal extent: duration; how long a person is engaging in behavior
Temporal locus: When the behavior occurs
What is count? number of responses emitted during observation period (i.e. how many time a child screams out)
What is a frequency count? Making a tally every-time a child screams out
Does measure alone provide sufficient information for analysis? No, it just tells you how long a behavior was engaged in.
How is frequency different from count? It gives you some form of time reference (i.e. in twenty minute period kiddo hit someone three times)
What is rate? How often something occurs in a certain time period; (i.e. the child hit someone 20 times in a six hour period)
What are guidelines for using rate? not appropriate for discrete trails (i.e. 5 out of 6 correct)
not appropriate for continuous behavior over extended period or time
What is celeration? measure the change in rate of responding per unit of time; tells you how frequency changes overtime
What is duration? the amount of time a behavior occurs; duration of each occurrence
What is response latency? measure of elapsed time between onset of stimulus and initiation of response (i.e. tell Jill to get to work and two minutes later she starts working)
What is interresponse time? Amount of time that elapses between two consecutive instances of a response class (i.e. you do one problem and then when does the next one begin)
What is a derivative measure?(percentage) A ratio formed by combining the same dimensional qualities; Expresses proportional quality; can be misleading (try to avoid)
What is trails-to-criterion? measure of the number of response opportunities needed to achieve a predetermined level of performance.
What is topography? The physical form or shape of a behavior (using senses to describe behavior)
What is magnitude? The force or intensity with which a response is emitted (i.e. measuring voice volume)
What is event recording? Procedures for detecting and recording the number of times a behavior is observed.
What are some considerations for event recording? easy to do, behavior must have discrete beginning and ending, rate must not be too high, and inappropriate for behaviors with long duration
What is timing? Procedures to measure duration, response, latency, and interresponse time
What are some devices that can measure duration? computer systems, stopwatch, wall clocks, tape recorder
What is time sampling:(whole-interval recording) Used to measure continuous behavior, Brief intervals, At end of interval, record if behavior occurred throughout, risk of underestimation; reported as percentage of intervals when behavior occurred
What is time sampling: partial-interval recording? At end of interval record if behavior occurred at any time during interval; multiple occurrences scored as one; Allows recording of multiple behaviors, reported as percentage of intervals when behavior occurred
What is momentary time sampling? record whether the behavior is occurring at the end of the interval; Does not require undivided attention; misses much behavior, and reported as percentage of intervals when behavior occurred
