QBA PRACTICE EXAM 2025/2026 QUESTIONS AND
SOLUTION RATED A+
✔✔Reactivity - ✔✔-refers to the effects of an assessment procedure on the behavior
being assessed
-most likely when observation is obtrusive
-person being observed is aware of the observer's presence and purpose
✔✔Relevance of Behavior Rule - ✔✔A target behavior should only be selected when it
can be determined that the behavior will produce reinforcement in the person's natural
environment.
✔✔Behavior Cusp vs. Pivotal Response - ✔✔Behavior Cusp- access to new
reinforcers, contingencies and environments.
Pivotal Behavior- once learned, produces corresponding or co-variations in other
adaptive UNTRAINED behaviors.
✔✔Respondent Behavior - ✔✔-The response component of the stimulus-response
reflex
-behavior that is elicited, or induced, by antecedent stimuli.
✔✔Science - ✔✔Systematic approach to the understanding of natural phenomena-as
evidenced by description, prediction and control.
✔✔Risk Factors (Autism Spectrum Disorder) - ✔✔-Intellectual disability and language
impairment
-Parental age, low birth weight, fetal effects
-Heritability 37-90%
-Difficulties in planning, coping with change, sensory sensitivity
✔✔Control - ✔✔The third and highest level of scientific understanding.
✔✔Experimentation - ✔✔the controlled comparison of some measure of the
phenomenon of interest (the dependent variable) under two or more different conditions
in which only one factor at a time (the independent variable) differs from one condition
to another.
✔✔Whole Interval Recording - ✔✔-the occurrence of the behavior is marked in an
interval only when the behavior occurs throughout the entire interval
-used to measure continuous behaviors and behaviors that occur at high rates
, -underestimates the overall percentage of the observation period in which the behavior
occurred
✔✔Partial-Interval Recording - ✔✔-a time sampling method in which the observer
records whether the target behavior occurred at any time during the interval
-overestimates the overall percentage of the observation period
-does not provide any information on duration per occurrence
✔✔Indicators of Trustworthy Measurement - ✔✔validity, accuracy, and reliability
✔✔Observer Drift - ✔✔When an observer alters the way they apply a measurement
leading to measurement error.
✔✔Total Count IOA - ✔✔-Simplest method for event recording IOA.
-Percentage of agreement between the total number of responses recorded by 2
observers.
-Calculated by dividing the smaller of the counts by the larger count & multiplying by
100.
-Overestimates the extent of actual agreement
✔✔CMO-R (reflexive) - ✔✔are those conditions or items that precede an aversive
event; thus making escape or avoidance highly reinforcing. They signal to us that bad
things could or are about to happen. (worsening condition)
✔✔CMO-T (transitive) - ✔✔re motivating conditions or stimulus that make us want/need
another stimulus. The best example are the conditions we find ourselves in when we
ask for help or engage in problem solving behaviors.
✔✔CMO-S (surrogate) - ✔✔Acquired its effectiveness by accompanying another MO,
and has the same value-altering and behavior-altering effect as the MO it has
accompanied. Ex: a picture of a cheeseburger on a menu, as well as an actual
cheeseburger.
✔✔Premack Principle - ✔✔A principle that states that making the opportunity to engage
in a high-probability behavior contingent on the occurrence of a low-frequency behavior
will function as reinforcement for the low-frequency behavior.
✔✔How long should a QBA safely store and secure client documents? - ✔✔7 years
