1. A psychologist is evaluating a new therapeutic intervention for reducing
social anxiety. She randomly assigns participants to either the new intervention
group or a control group that receives no treatment. To minimize the influence
of participant expectations, she ensures that the participants are unaware of
which group they are in. However, the therapists delivering the intervention are
aware of each participant's group assignment. This study design is best
described as which of the following?
A. Double-blind
B. Single-blind
C. Correlational
D. Within-subjects
Correct Answer: B. Single-blind
Rationale: A single-blind study is one in which the participants are unaware of their
group assignment, but the researchers or experimenters are aware. This design
helps control for placebo effects from the participants' perspective. A double-blind
study (A) would require both participants and researchers to be unaware of the
assignment. The study is experimental, not correlational (C), as it involves
manipulation of a variable. A within-subjects design (D) would involve each
participant experiencing both conditions, which is not described.
,2. Which of the following scenarios best illustrates the concept of top-down
processing in perception?
A. Recognizing a familiar song even when it is played in a different key and at a
faster tempo.
B. Seeing a red apple and perceiving its color based on the wavelengths of light
reflecting from its surface.
C. Detecting the sudden movement of a car in your peripheral vision while
walking down a busy street.
D. Feeling the sharpness of a pinprick on your finger and immediately pulling
your hand away.
Correct Answer: A. Recognizing a familiar song even when it is played in a
different key and at a faster tempo.
Rationale: Top-down processing is guided by higher-level cognitive processes, such
as prior knowledge, expectations, and context, to interpret sensory information.
Recognizing a familiar song despite alterations in its physical properties (key and
tempo) requires using memory and experience to interpret the sensory input.
Options B, C, and D are primarily examples of bottom-up processing, where
perception is built directly from the basic sensory information (light wavelengths,
movement detection, and pain signals).
3. A researcher is investigating the effect of sleep deprivation on working
memory performance. She operationally defines "sleep deprivation" as "less
than four hours of sleep the night prior to testing" and "working memory" as
"the number of digits correctly recalled on a standardized digit-span test."
,Which of the following is a potential limitation of this operational definition of
sleep deprivation?
A. It may not be a valid measure of the construct of sleep deprivation.
B. It is too broad and could include individuals who slept for 10 hours.
C. It is a purely correlational measure and cannot be used in an experiment.
D. It is too easily manipulated by participants in the study.
Correct Answer: A. It may not be a valid measure of the construct of sleep
deprivation.
Rationale: An operational definition must accurately represent the construct it is
intended to measure. Defining sleep deprivation solely as "less than four hours of
sleep" might not be valid for everyone, as some individuals may be severely
impaired by five hours of sleep while others may function relatively well on three
hours. It is specific, not broad (B), can be used in an experiment (C), and while
participants might misreport sleep, that is an issue of reliability and honesty, not
the definition's primary limitation (D).
4. During a heated debate, one participant, Alex, insists that their viewpoint is
objectively correct and refuses to consider evidence that contradicts their initial
position. Alex's friend points out that Alex is "only seeing what they want to
see." This observation most directly aligns with the concept of:
A. Confirmation bias
B. Hindsight bias
C. Availability heuristic
D. The framing effect
, Correct Answer: A. Confirmation bias
Rationale: Confirmation bias is the tendency to seek out and favor information that
confirms one's pre-existing beliefs while ignoring or undervaluing contradictory
evidence. This behavior is directly described in the scenario. Hindsight bias (B) is the
"I-knew-it-all-along" phenomenon. The availability heuristic (C) involves making
judgments based on how easily examples come to mind. The framing effect (D) is
the influence of how information is presented on decision-making.
5. In the context of classical conditioning, extinction occurs when the:
A. Conditioned stimulus is repeatedly presented without the unconditioned
stimulus.
B. Unconditioned stimulus is repeatedly presented without the conditioned
stimulus.
C. Conditioned response is strengthened through reinforcement.
D. Neutral stimulus is paired with a conditioned stimulus.
Correct Answer: A. Conditioned stimulus is repeatedly presented without the
unconditioned stimulus.
Rationale: Extinction in classical conditioning happens when the conditioned
stimulus (CS), which previously signaled the unconditioned stimulus (US), is
presented alone, repeatedly, without the US. This leads to a weakening and
eventual disappearance of the conditioned response (CR). Option B describes a
situation that is not standard extinction. Option C describes reinforcement, and
Option D describes a higher-order conditioning procedure.
