QUESTIONS AND
CORRECT ANSWERS
GRADED A+ 2025-2026
continuous measurement - ANS-record every behavior occurrence (includes frequency,
rate, duration, latency, and inter-response time)
frequency - ANS-count every time the behavior occurs, have an obvious beginning/end
rate - ANS-how much behavior occurs per time, useful if sessions vary in time
duration - ANS-total extent of time a behavior occurs, clear beginning/end
latency - ANS-how long it takes a child to respond to your instruction, time between
onset of the stimulus to the initiation of the response
inter-response time (IRT) - ANS-time between two successive responses, used for
shortening/lengthening between actions
discontinuous measurement - ANS-interval recording, split a session into pieces of
time
whole interval recording - ANS-behavior has to occur during the whole interval to
count, good for increasing behavior
, partial interval recording - ANS-engaged in behavior at some point in the interval, good
for decreasing behavior
momentary time sampling - ANS-choose a specific time and see if the behavior is
occurring at that time, good for multiple learners
permanent product - ANS-anything you can see after the behavior occurred (hole in the
wall, completed homework, etc.)
operational definition - ANS-should be specific, observable, have inter-observer
agreement (IOA)
reinforcer - ANS-something you present after a behavior occurs which makes it more
likely to occur in the future
preference assessment - ANS-done to find objects and activities for which the learner
has a higher preference for, shift over time and vary by setting
types of preference assessments - ANS-asking, free operant, trial based
preference assessment- asking - ANS-ask the learner or someone that knows them well,
pre-task choice
preference assessment- free operant - ANS-learner is free to roam the environment,
you just observe/measure how much time spent with each object, can be naturalistic
or contrived
preference assessment- trial based - ANS-present stimuli in trials, can be single
stimuli/successive choice, paired stimuli/forced choice, or multiple stimuli with or
without replacement
reinforcer assessment - ANS-present preferred items after behavior occurs and see how
strong they are as reinforcers
