ABA 624 Final Exam Prep ACTUAL
QUESTIONS AND CORRECT ANSWERS
Measurement - CORRECT ANSWER The process of applying quantitative labels to describe
and differentiate objects and natural events
Repeatability - CORRECT ANSWER instances of a behavior can occur repeatedly through
time
Temporal extent - CORRECT ANSWER every instance of behavior occurs during some
amount of time
Temporal locus - CORRECT ANSWER every instance of behavior occurs at a certain point in
time with respect to other events
Count - CORRECT ANSWER 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.
Rate - CORRECT ANSWER the number of responses per unit of time
Ex) count per seconds, count per minute, count per hour, count per day
Free operant - CORRECT ANSWER 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
Discrete trial - CORRECT ANSWER Response rates of behaviors occurring within a
controlled opportunity to emit the response.
Celeration - CORRECT ANSWER a measure of how rates of response change over time
-should use acceleration and deceleration when describing increasing or decreasing rates of response
-celeration is a measure of count per unit time/per unit of time
-celeration is a direct measure of dynamic patters of behavior change
,Duration - CORRECT ANSWER the amount of time from the onset to the end of a response, is
the basic measure of temporal extent
-Important when measuring the amount of time a person engages in target bx
Total duration per session - CORRECT ANSWER a measure of the cumulative time a person
engages in the target bx
-cummalative amount of time target bx during observation
-amount of time a person spend completing task
Duration per occurence - CORRECT ANSWER a measure of the duration of time that each
instance of the target behavior occurs
Latency - CORRECT ANSWER measure of the elapsed time between the onset of a stimulus
and the initiation of a subsequent response
Interresponse time - CORRECT ANSWER Amount of time that elapses between two
consecutive instances of a response class
-shorter irts coexist with higher rates of response
-longer irts occur within lower response rates
-meaure IRT when the time between instances of response class is important
-provides a basic measure for implementing and evaluating interventions using differential rx of low
and high rates
-displayed in graph by mean or median and range per observation period
Derivative measures - CORRECT ANSWER Percentage
Trials-to-Criterion
Percentage - CORRECT ANSWER a ratio formed by combining the same dimensional
quantities such as count or time
-number of times the event occurred per 100 opportunities
-used to report response accuracy, proportion of observation intervals target bx occurred
-limations: small divisor are unduly affected by small changes in bx, no dimensional quantities, lower
and upper limits on data
, Trials to criterion - CORRECT ANSWER Measure of the number of response opportunities
needed to achieve a predetermined level of performance
-aspect of cost of treatment to compare treatment
Topography - CORRECT ANSWER the physical form or shape of a behavior, is a measurable
and malleable dimension of bx
Magnitude - CORRECT ANSWER the force or intensity with which a response is emitted
Event recording - CORRECT ANSWER encompasses a wide variety of procedures for
detecting and recording the number of times a behavior of interest occurs
-used to measure discrete trial bxs
-consideration: each instance of target bx must have discrete beginning and ending, no high rates of
bxs or extended periods of time
Time sampling - CORRECT ANSWER a variety of methods for observing and recording
behavior during intervals or at specific moments in time
-procedure: divide observation period, record the absence of bx within or at end of interval
-ex) whole interval, partial interval, momentary time sampling
Whole interval recording - CORRECT ANSWER -often used to measure continuous behaviors
-observation period: divided into a series of time intervals, at end of the interval the observer records
whether the target bx occurred throughout the interval
-often underestimates overall percentage of observation period in which the bx actually occurred
-data: reported as percentage of the total intervals in which target bx was recorded as occurring, yield
an estimate of total duration
Partial interval recording - CORRECT ANSWER the observer records whether the behavior
occurred at any time during the interval
-partial interval is not concerned with how many times the bx occur during the interval or how long
the bx was present, possible to measure multiple bxs concurrently
-often overestimates the overall percentage of the observation period that the bx actually occurred
