EXAM
1. A researcher wants to determine whether a newly developed
cognitive-behavioral intervention causes a reduction in depressive
symptoms. Participants are randomly assigned to either the intervention
group or a control group, and depressive symptoms are measured before
and after treatment. Which feature provides the strongest basis for
making a causal inference?
A. Random assignment to conditions
B. Use of a large sample
C. High internal consistency of the depression measure
D. Correlation between treatment participation and symptom
improvement
Answer: A. Random assignment to conditions
Rationale: Random assignment helps distribute preexisting participant
characteristics across conditions, reducing systematic selection
differences and strengthening causal inference. A large sample improves
precision but does not itself establish causality. Reliability of the
measure is important but is not equivalent to experimental control.
2. A psychologist obtains a correlation of r = .80 between two measures
of anxiety. What proportion of variance is shared between the two
measures?
,2|Page
A. 8%
B. 16%
C. 64%
D. 80%
Answer: C. 64%
Rationale: The coefficient of determination is obtained by squaring the
correlation: r² = .80² = .64. Therefore, approximately 64% of the
variance is shared between the two variables.
3. A psychological test has excellent reliability but demonstrates poor
validity because it consistently measures a construct different from the
one it was intended to assess. Which principle is best illustrated?
A. Reliability guarantees validity
B. Reliability is necessary but does not by itself establish validity
C. Validity is unrelated to reliability
D. A reliable test cannot have systematic error
Answer: B. Reliability is necessary but does not by itself establish
validity
Rationale: Reliability concerns consistency or dependability of
measurement, whereas validity concerns whether the instrument
supports the intended interpretation and use of scores. A test can be
highly consistent while consistently measuring the wrong construct.
4. A psychologist develops a measure of depression and compares scores
on the new instrument with scores from a well-established depression
inventory administered during the same assessment session. Which type
of validity evidence is being evaluated?
,3|Page
A. Predictive validity
B. Concurrent validity
C. Content validity
D. Face validity
Answer: B. Concurrent validity
Rationale: Concurrent validity involves examining whether scores on a
new measure correspond appropriately with an established measure of
the same or closely related construct collected at approximately the same
time.
5. A psychological assessment has a sensitivity of 90%. Which
interpretation is most accurate?
A. Ninety percent of people who test positive actually have the disorder
B. Ninety percent of people who have the disorder are correctly
identified by the test
C. Ten percent of people without the disorder will test negative
D. Ninety percent of positive tests are false positives
Answer: B. Ninety percent of people who have the disorder are
correctly identified by the test
Rationale: Sensitivity is the proportion of individuals who truly have a
condition who receive a positive test result. High sensitivity means the
test has relatively few false negatives.
6. A psychologist is selecting a screening instrument for a disorder
where missing a true case would have serious consequences. Which
characteristic is especially desirable?
, 4|Page
A. High sensitivity
B. Low sensitivity
C. Low reliability
D. Low criterion validity
Answer: A. High sensitivity
Rationale: When the primary concern is avoiding missed cases, high
sensitivity is particularly important because it reduces false-negative
results.
7. Which brain structure is most directly associated with the
consolidation of new declarative memories?
A. Hippocampus
B. Medulla
C. Cerebellar vermis
D. Primary motor cortex
Answer: A. Hippocampus
Rationale: The hippocampal formation plays a critical role in forming
and consolidating new declarative memories. Damage can produce
significant anterograde memory impairment.
8. A patient sustains damage to the amygdala. Which psychological
function would most likely be affected?
A. Emotional processing, particularly fear-related learning
B. Primary visual acuity
C. Spinal reflexes
D. Basic auditory conduction
