A psychologist wants to determine whether listening to instrumental music while
studying affects exam performance. One group studies with music, and another studies
in silence. Students' exam scores are then compared.
Which variable is the independent variable?
A. Students' exam scores
B. The study environment (music or silence)
C. Students' intelligence
D. Time spent studying
Correct Answer: B. The study environment (music or silence)
Explanation:
The independent variable is the factor manipulated by the researcher. In this study,
the researcher changes whether students study with music or in silence. Exam
scores are the dependent variable because they are the measured outcome.
Question 2
Which neurotransmitter plays a major role in voluntary movement, motivation, and
reward processing?
A. GABA
B. Serotonin
1|Page
,C. Dopamine
D. Acetylcholine
Correct Answer: C. Dopamine
Explanation:
Dopamine is associated with movement, motivation, learning, and the brain's
reward pathways. Loss of dopamine-producing neurons contributes to Parkinson's
disease.
Question 3
A child cries whenever she sees a white coat because she previously received several
painful vaccinations from nurses wearing white coats.
This is an example of:
A. Operant conditioning
B. Classical conditioning
C. Observational learning
D. Insight learning
Correct Answer: B. Classical conditioning
Explanation:
A previously neutral stimulus (white coat) became associated with an
unconditioned stimulus (painful injections), producing a conditioned emotional
response.
Question 4
Which brain lobe is primarily responsible for planning, reasoning, decision-making, and
voluntary movement?
2|Page
, A. Temporal lobe
B. Occipital lobe
C. Frontal lobe
D. Parietal lobe
Correct Answer: C. Frontal lobe
Explanation:
The frontal lobe contains the primary motor cortex and regions involved in
executive functions such as planning, judgment, problem-solving, and impulse
control.
Question 5
According to Piaget, a child who understands that the amount of liquid remains the
same after it is poured into a differently shaped container has developed:
A. Object permanence
B. Egocentrism
C. Conservation
D. Symbolic thinking
Correct Answer: C. Conservation
Explanation:
Conservation is the understanding that quantity remains unchanged despite
changes in appearance. It typically develops during the concrete operational stage.
Question 6
Which reinforcement schedule typically produces the highest rate of responding and is
the most resistant to extinction?
