Chapter 4: Measuring Behavior Flashcards
an outcome or result that appears to exist because of the way it is measured but in fact does not correspond to what actually occurred.
Artifact
the change (acceleration or deceleration) in rate of responding over time; based on count per unit of time (rate); expressed as a factor by which responding is accelerating or decelerating (multiplying or dividing); displayed with a trend line on a standard Celeration chart. Celeration is a generic term without specific reference to accelerating or decelerating rates of response.
celeration
a unit of time (e.g. per week, per month) in which celeration is plotted in a standard Celeration Chart
Celeration time period
the celeration trend line is measured as a factor by which rate multiples or divides access the celeration time periods (e.g. rate per week, rate per month, rate per year, rate per decade)
Celeration trend line
a simple tally of the number of occurrences of a behavior. The observation period, or counting time, should always be noted when reporting count measures
Count
any operant whose response rate is controlled by a given opportunity to emit the response. Each discrete response occurs when an opportunity to respond exists. discrete trail, restricted operant and controlled operant are synonymous technical terms
Discrete trial
a measure of the total extent of time in which a behavior occurs
Duration
measurement procedure for obtaining a tally or count of the number of times a behavior occurs.
Event Recording
any operant behavior that results in minimal displacement of the participant in time and space. A free operant can be emitted at nearly any time, it is discrete, it requires minimal time for completion and it can produce a wide range of response rates. Examples in aba include a. The number of words read allowed during a 1minute couldn’t period b the themuver of hand slap’s per 6 seconds and c the number of letter strokes written in 3 minutes (contrast with discrete trial)
Free Operant
a ratio of count per observation time, often expressed as count per stand unit of time (per minute , per hour per day and calculated by doing the number of responses rescued by the number of standard units of time in which observations were conducting uned interchangeable y with rate
Frequency
- a measure of temporal locus; defined as the elapsed time between two successive responses.
Inter response time (IRT)
the force or intensity with which a response is emitted’ provides important quantitative parameters used in defining and verifying the occurrence of some response classes. Responses meeting those criteria are measured and reported by one or more fundamental or derivative measures such as frequency, duration or latency. Sometimes called amplitude
Magnitude
a method of measuring behavior after it has occurred by recording the effects that the behavior produced on the environment.
Measurement by permanent product
a measurement method in which the presence or absence of behaviors are recorded precisely specified time intervals (contrast with interval recording)
Momentary Time Sample
a time sampling method for measuring behavior in which the observation period is divided into a series of brief time intervals (typically from 5 to 10 seconds). The observer records whether the target behavior recording is not concerned with how many times behavior occurred during the interval or how long the behavior was present just that it occurred at some point during the interval; TENDS TO OVERESTIMATE the proportion of the observation period that the behavior actually occurred .
Partial Interval Recording
