EDF 6225 Exam #2 CORRECT QUESTIONS &
SOLUTIONS(RATED A)
Functional Relationship - ANSWER the results of an experiment that describe the occurrence of the
phenomena under study as a function of the operation of one or more specified and controlled variables
in the experiment in which specific change in one event (dependent variable) can be produced by
manipulating another event (the independent variable) and that the change in the dependent variable
was unlikely the result of other factors (confounding variable).
Functional Relationship - ANSWER It shows specific manipulations of one event (IV) produce a change in
other events (DV) and that change in the DV was unlikely the result of extraneous factors (confounding
variables)- this finding is the....
Independent Variable (IV) - ANSWER The variable that is systematically manipulated by the researcher in
an experiment to see whether changes in the independent variable produce reliable changes in the
dependent variable. In applied behavior analysis, it is usually an environment event or condition
antecedent or consequent to the dependent variable. (sometimes called the intervention or treatment
variable)
Dependent Variable (DV) - ANSWER The measured behavior in an experiment to determine if it changes
as a result of manipulations of the independent variable; in applied behavior analysis, it represents some
measure of a socially significant behavior. (Target behavior)
antecedent - ANSWER is the environmental conditions or stimulus changes that exist or occur prior to
the behavior of interest.
Behavior - ANSWER An organism's interaction with the environment.
Consequence - ANSWER is anything immediately following a behavior in which we are interested.
Stimulus Class - ANSWER A group of stimuli that are similar along one or more dimensions (for example,
they look or sound similar, they have a common effect on behavior, or they occur at similar times relative
to the response).
, Stimulus Class - ANSWER You show a student a banana, kiwi, strawberry and plum. You ask the student,
"What are these?" The student says, "Fruit", even though they are all different fruits.
Response Class - ANSWER is a group of responses that produce the same effect on the environment. (in
other words, several behaviors that have the same function.)
Response Class - ANSWER A patient engages in head banging, screaming, and hitting staff which all
produce the same effect on the environment; the patient can escape their non-preferred therapies.
The 4 Reinforcer Dimensions - ANSWER Rate of reinforcement, Quality of reinforcement, Reinforcer
Delay, and Response effort.
Rate of reinforcement - ANSWER is the number of reinforcements per time
Quality of reinforcement - ANSWER how good is that reinforcer compared to other similar reinforcers
Reinforcer Delay - ANSWER refers to whether access to reinforcers earned was immediate or delayed.
Response Effort - ANSWER the amount of effort a person must put forth to successfully complete a
specific behavior and can have a direct impact on the frequency with which the person will engage in
that behavior
Hernstein's Matching Law - ANSWER says that we (animals including humans) perform behaviors in a
ratio that matches the ratio of available reinforcement for those behaviors.
The matching law - ANSWER suggests that when different schedules of reinforcement are available at
the same time for different behaviors, individuals will distribute their behavior according to the relative
rates of reinforcement available for each option.
Time-out - ANSWER The immediate response-contingent withdrawal of opportunity to earn positive
reinforcement or the immediate loss of access to positive reinforcers for a specified time; a form of
negative punishment.
