ABA 622 PRE TEST EXAMPREP QUESTIONS
AND DETAILED SOLUTIONS
◉ duration.
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.
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.
Answer: a measure of the duration of time that each instance of the
target behavior occurs
◉ latency.
Answer: measure of the elapsed time between the onset of a
stimulus and the initiation of a subsequent response
,◉ interresponse time.
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.
Answer: Percentage
Trials-to-Criterion
◉ percentage.
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.
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.
Answer: the physical form or shape of a behavior, is a measurable
and malleable dimension of bx
◉ magnitude.
Answer: the force or intensity with which a response is emitted
◉ event recording.
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.
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.
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.
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
