,Liberty University PSYC 320 Quiz 2 | Behavior Modification (2026) Q&A
1. The primary purpose of measuring behavior is to:
A) Increase punishment
B) Objectively evaluate behavior and intervention effectiveness
C) Diagnose personality
D) Reduce motivation
Correct Answer: Objectively evaluate behavior and intervention effectiveness
Rationale: Measuring behavior allows for objective evaluation of the behavior and the
effectiveness of interventions. It is not used to increase punishment, diagnose personality, or
reduce motivation. Measurement is essential for determining whether behavior change has
occurred.
2. Which characteristic of behavior makes it measurable?
A) It is observable.
B) It is emotional.
C) It is theoretical.
D) It is unconscious.
Correct Answer: It is observable.
Rationale: Behavior is measurable because it is observable and can be recorded by others.
Emotional, theoretical, and unconscious processes are not directly observable and therefore
not the primary focus of behavior modification measurement.
3. Frequency recording measures:
A) How long behavior lasts
B) How often behavior occurs
C) Time before behavior starts
,D) Intensity of behavior
Correct Answer: How often behavior occurs
Rationale: Frequency recording measures the number of times a behavior occurs. Duration
recording measures how long a behavior lasts, latency measures the time before behavior
starts, and intensity measures the physical force involved.
4. Duration recording measures:
A) Number of responses
B) Length of time a behavior occurs
C) Time between responses
D) Percentage of behavior
Correct Answer: Length of time a behavior occurs
Rationale: Duration recording measures the length of time a behavior occurs, from start to
finish. Frequency measures the number of responses, latency measures time between
responses, and percentage is a derived measure.
5. Latency refers to:
A) The intensity of a behavior
B) The time from a stimulus to the start of a behavior
C) The duration of a behavior
D) The frequency of a behavior
Correct Answer: The time from a stimulus to the start of a behavior
Rationale: Latency is the time elapsed from a specific event or stimulus to the initiation of a
behavior. It is one of the four dimensions of behavior, along with frequency, duration, and
intensity.
, 6. Baseline data should be collected:
A) Before intervention begins
B) After reinforcement starts
C) During extinction only
D) At the end of treatment
Correct Answer: Before intervention begins
Rationale: Baseline data are collected before any intervention to establish a starting point
against which behavior change can be measured. This allows for objective evaluation of
intervention effectiveness.
7. Reliability refers to:
A) Consistency of measurement
B) Number of observations
C) Client motivation
D) Treatment cost
Correct Answer: Consistency of measurement
Rationale: Reliability refers to the consistency and stability of measurement. A reliable
measure produces similar results under similar conditions. It is not about the number of
observations, client motivation, or treatment cost.
8. Interobserver agreement assesses:
A) Consistency between observers
B) Reinforcer preference
C) Client satisfaction
D) Treatment duration
