1. A researcher wants to determine if sleep deprivation affects cognitive performance.
Participants are randomly assigned to either sleep for 8 hours or remain awake for 24
hours before completing a memory recall test. What is the independent variable in this
experimental study guide practice test?
A. The score achieved on the memory recall test
B. The group of participants sleeping 8 hours
C. The amount of sleep participants receive
D. The age and baseline memory capacity of the participants
Answer: C
The independent variable is the factor directly manipulated by the experimenter to observe
its effect. In this study guide scenario, the amount of sleep allowed (8 hours versus 24 hours of
wakefulness) is manipulated, while performance on the memory test serves as the dependent
variable.
2. Dr. Chen is conducting an observational study in a high school cafeteria to evaluate peer
interactions without intervening. Which research method is being utilized in this exam
prep scenario?
A. Naturalistic observation
B. Case study
C. Controlled experiment
D. Correlational study
Answer: A
Naturalistic observation involves observing subjects in their natural environment without
intervention or manipulation by the researcher. This technique provides high ecological
validity for real-world behavior analysis.
3. A patient suffers damage to Wernicke's area following a localized stroke. Which clinical
symptom will the patient most likely exhibit during an evaluation?
A. Complete loss of motor control in the dominant right hand
B. Inability to produce fluent, articulate spoken language
C. Impaired language comprehension with fluent but nonsensical speech
D. Severe disruption in forming new long-term episodic memories
,Answer: C
Wernicke's area, located in the left temporal lobe, is responsible for language comprehension.
Damage leads to receptive aphasia, characterized by fluent speech that lacks semantic
meaning and significant deficits in understanding written or spoken language.
4. During a neuron's resting potential, which statement accurately describes the electrical
charge and ion distribution across the neural membrane?
A. The inside of the neuron is positively charged relative to the outside, with high sodium
concentrations inside.
B. The inside of the neuron is negatively charged relative to the outside, with higher potassium
inside and higher sodium outside.
C. The membrane potential is neutral, with equal concentrations of sodium and potassium on
both sides.
D. The inside of the neuron is negatively charged, caused strictly by an abundance of
extracellular chloride ions.
Answer: B
At resting potential (approximately -70mV), the interior of the neuron maintains a negative
charge relative to the extracellular fluid. This state is actively maintained by the sodium-
potassium pump, keeping high potassium concentrations inside and high sodium
concentrations outside.
5. A developmental psychologist tests conservation of liquid with a 5-year-old child. Water
is poured from a short, wide glass into a tall, narrow glass. The child claims the tall glass
now holds more water. According to Piaget, which cognitive stage is demonstrated?
A. Sensorimotor
B. Preoperational
C. Concrete operational
D. Formal operational
Answer: B
The preoperational stage (ages 2–7) is characterized by centration and egocentrism. Children
in this stage lack the concept of conservation—the understanding that quantity remains
constant despite changes in physical appearance or shape.
6. An individual experiences sudden, intense episodes of terror accompanied by heart
palpitations, shortness of breath, and fear of losing control, occurring without an obvious
trigger. Which diagnosis is most consistent with these verified symptoms?
A. Generalized Anxiety Disorder
B. Specific Phobia
,C. Panic Disorder
D. Obsessive-Compulsive Disorder
Answer: C
Panic Disorder is characterized by recurrent, unexpected panic attacks accompanied by
persistent concern about future attacks or significant behavioral changes related to the
attacks.
7. In classical conditioning, a neutral stimulus is repeatedly paired with an unconditioned
stimulus until it triggers a conditioned response. What term describes the initial learning
stage where this association is established?
A. Extinction
B. Acquisition
C. Spontaneous recovery
D. Stimulus generalization
Answer: B
Acquisition is the initial stage of learning in classical conditioning during which a neutral
stimulus becomes associated with an unconditioned stimulus, eventually eliciting the
conditioned response reliably.
8. Which neurotransmitter operates as the primary inhibitory neurotransmitter in the
human central nervous system?
A. Glutamate
B. Acetylcholine
C. GABA (Gamma-aminobutyric acid)
D. Dopamine
Answer: C
GABA is the chief inhibitory neurotransmitter in the brain, hyperpolarizing postsynaptic
membranes to decrease likelihood of action potentials. Glutamate serves as the primary
excitatory neurotransmitter.
9. A student studies for an exam in the same quiet room where the test will later be
administered, scoring significantly higher than peers who studied in a noisy library. Which
memory phenomenon accounts for this difference?
A. State-dependent memory
B. Context-dependent memory
C. Proactive interference
D. Serial position effect
, Answer: B
Context-dependent memory refers to the enhanced recall of information when the
environmental context during retrieval matches the physical context present during encoding.
10. Which psychological perspective emphasizes free will, self-actualization, and human
potential for personal growth?
A. Behavioral perspective
B. Psychoanalytic perspective
C. Humanistic perspective
D. Evolutionary perspective
Answer: C
Humanistic psychology, pioneered by Carl Rogers and Abraham Maslow, focuses on conscious
experience, personal growth, human potential, and the innate drive toward self-actualization.
11. A study finds a strong negative correlation (r = -0.85) between screen time before bed
and total duration of deep REM sleep. What is the correct interpretation of this finding?
A. Increased screen time directly causes reduced REM sleep duration.
B. Decreased sleep duration causes individuals to spend more time on screens.
C. As screen time before bed increases, deep REM sleep duration tends to decrease.
D. Screen time and sleep duration operate completely independently without a mathematical
relationship.
Answer: C
A negative correlation indicates an inverse relationship where high values of one variable
correspond with low values of another. Correlation does not prove causation.
12. In a classic experiment by Solomon Asch, participants conformed to an obviously
incorrect group consensus regarding line lengths. Which social influence principle explains
this behavior?
A. Informational social influence
B. Normative social influence
C. Deindividuation
D. Group polarization
Answer: B
Normative social influence occurs when individuals conform to group standards to gain social
approval, fit in, or avoid social rejection, even when knowing the group's stance is incorrect.
