VERIFIED ANSWERS/ ALREADY GRADED A+ (BRAND

1. A behavior analyst is conducting a functional analysis of
self-injurious behavior. The analyst hypothesizes that the
behavior is maintained by automatic reinforcement. Which
philosophical assumption underlies the decision to test this
hypothesis through direct manipulation rather than relying on
the client's verbal report?
A. Radical behaviorism
B. Methodological behaviorism
C. Structuralism
D. Mentalism
Correct Answer: A. Radical behaviorism
Rationale: Radical behaviorism, as developed by B.F. Skinner,
includes private events (thoughts, feelings) within the purview of
behavioral analysis but insists that they should not be used to
explain other behaviors . Methodological behaviorism excludes
1
,private events entirely. The decision to test the hypothesis through
direct environmental manipulation rather than relying on verbal
report reflects radical behaviorism's commitment to functional
relations between environment and behavior. Mentalism would
explain the behavior by appealing to unobservable inner
causes .
2. A behavior analyst observes that a child's tantrums occur
more frequently when the child has not eaten for several
hours. The analyst manipulates pre-session meal consumption
and measures tantrum frequency. This approach BEST reflects
which attitude of science?
A. Determinism
B. Empiricism
C. Parsimony
D. Pragmatism
Correct Answer: A. Determinism
Rationale: Determinism is the assumption that behavior is lawful
and orderly—that it has identifiable causes that can be
discovered through systematic manipulation . The analyst is
assuming that the tantrums are determined by an environmental
variable (food deprivation/satiation). Empiricism refers to
2
,objective observation; parsimony refers to choosing the simplest
explanation; pragmatism refers to evaluating truth by practical
consequences. The analyst's assumption that the tantrum has a
cause that can be experimentally identified reflects determinism .
3. A behavior analyst observes a child's aggressive behavior
and immediately intervenes with a time-out procedure. After
three sessions, the aggressive behavior decreases. The
analyst concludes that time-out was effective. Which
assumption of science is being applied when the analyst
attributes the behavior change to the intervention rather than
other possible factors?
A. Parsimony
B. Empiricism
C. Replication
D. Philosophical doubt
Correct Answer: A. Parsimony
Rationale: Parsimony is the assumption that simple, logical
explanations should be ruled out before more complex
explanations are considered . The analyst is using parsimony by
concluding that the intervention caused the behavior change (the
simplest explanation consistent with the data) rather than
3
, invoking unknown or complex variables. Empiricism is data-based
observation; replication is repeating experiments; philosophical
doubt is continuously questioning conclusions .
4. A researcher publishes a study showing that a new
intervention reduced stereotypic behavior. A behavior analyst
reads the study and attempts to replicate the procedures with
a different participant population. This practice BEST illustrates
which scientific attitude?
A. Parsimony
B. Replication
C. Determinism
D. Experimentation
Correct Answer: B. Replication
Rationale: Replication is the repetition of experiments to
determine the reliability and generality of findings . By
attempting to replicate the study with a different population, the
analyst is evaluating whether the intervention effects are reliable
and generalizable. Determinism is the assumption that behavior
has causes; experimentation is the systematic manipulation of
variables; parsimony is preferring simpler explanations.
