Q1.
In a double-blind study testing a new antidepressant, the experimental group shows a
statistically significant reduction in depression scores compared to placebo. However, the
effect size is small (Cohen's d = 0.2). Which conclusion is most justified?
A. The drug is clinically ineffective despite B. The drug has a statistically significant but
statistical significance. potentially trivial effect.
C. The study lacks internal validity due to D. The placebo effect is larger than the drug
small effect size. effect.
Correct: B - The drug has a statistically significant but potentially trivial effect.
Rationale:Statistical significance indicates the result is unlikely due to chance, but a small
effect size (d=0.2) means the actual difference is minimal, raising questions about clinical
meaningfulness. Option A is too absolute; small effects can still be clinically relevant in some
contexts. Option C confuses internal validity with effect size. Option D is not directly
supported without direct comparison.
Q2.
A researcher finds that scores on a working memory task correlate r = 0.60 with scores on
a fluid intelligence test. Which interpretation is most accurate?
A. Working memory capacity explains 60% B. There is a strong positive relationship, but
of the variance in fluid intelligence. causality cannot be inferred.
C. Fluid intelligence causes higher working D. The correlation is weak and likely due to
memory performance. a third variable.
Correct: B - There is a strong positive relationship, but causality cannot be inferred.
Rationale:A correlation of 0.60 indicates a strong positive relationship (r^2 = 0.36, so 36%
variance explained, not 60%). Option A incorrectly states the variance explained. Correlation
does not imply causation, so Option B is correct; Option C assumes directionality. Option D
misinterprets the strength; 0.60 is considered strong in psychology.
Q3.
A patient exhibits impaired voluntary movement but intact reflexive responses. Brain
imaging reveals a lesion in the primary motor cortex. Which additional finding is most
likely?
A. Loss of sensation in the contralateral B. Difficulty initiating movements (akinesia)
body

, Section A - History AND Approaches TO Psychology
C. Inability to perform coordinated D. Contralateral paralysis (hemiplegia)
sequences (apraxia)
Correct: D - Contralateral paralysis (hemiplegia)
Rationale:The primary motor cortex controls voluntary movement on the contralateral side of
the body; a lesion causes contralateral paralysis or paresis. Option A is associated with
somatosensory cortex damage. Option B is characteristic of basal ganglia disorders like
Parkinson's. Option C typically involves parietal or premotor areas.
Q4.
In a classical conditioning experiment, a tone is paired with a mild shock until the tone
elicits a fear response. Subsequently, the tone is presented repeatedly without the shock,
and the fear response gradually weakens. This process is called:
A. Extinction B. Spontaneous recovery
C. Stimulus generalization D. Habituation
Correct: A - Extinction
Rationale:Extinction is the reduction of a conditioned response when the conditioned
stimulus is presented without the unconditioned stimulus. Spontaneous recovery is the
reappearance of the response after a rest period. Generalization involves responding to
similar stimuli. Habituation is a decrease in response to a repeated non-threatening stimulus.
Q5.
A researcher uses fMRI to measure brain activity while participants view emotional faces.
Compared to neutral faces, fearful faces show increased activation in the amygdala. This
finding supports the amygdala's role in:
A. Emotional regulation and reappraisal B. Detection of threat and fear processing
C. Memory consolidation for emotional D. Social reward processing
events
Correct: B - Detection of threat and fear processing
Rationale:The amygdala is critically involved in detecting threats and processing fear,
especially to fearful faces. Option A involves prefrontal cortex. Option C relates to the
hippocampus and amygdala interaction. Option D is more associated with the ventral
striatum.
Q6.
According to Piaget, a child in the concrete operational stage fails a conservation of liquid
task because she focuses on the height of the water rather than the width. This error is
due to:
