*INTRODUCTION*
The purpose of this comprehensive assessment is to evaluate mastery of the foundational concepts, theories, and empirical methodologies
required by the advanced placement psychology curriculum. This exam measures critical thinking, analytical reasoning, and the application of
psychological principles to diverse human behaviors. Comprising rigorous multiple-choice questions and complex clinical, experimental, and
real-world scenarios, the assessment demands deep analytical decision-making. Candidates must demonstrate proficiency in evaluating
ethical guidelines, interpreting statistical data, and distinguishing between overlapping psychological perspectives, ensuring readiness for
upper-level collegiate psychological inquiry.
SECTION ONE: QUESTIONS 1–100
Question 1
A researcher wants to study the effects of sleep deprivation on cognitive performance. She randomly assigns participants to either a 4-hour
sleep group or an 8-hour sleep group and then measures their reaction times on a computer task. In this experiment, the independent
variable is the:
A. Reaction time on the computer task
B. Level of cognitive performance
🟢 C. Amount of sleep allowed
D. Individual sleep habits of the participants
,🔴 RATIONALE: The independent variable is the factor manipulated by the experimenter to observe its effects. Here, the researcher directly
manipulates the hours of sleep. Reaction time is the dependent variable measured to assess the impact.
Question 2
Dr. Sanchez is treating a patient with severe depression. He prescribes a medication that increases the availability of serotonin in the
synaptic cleft by preventing its reabsorption into the presynaptic neuron. This type of drug acts as an:
🟢 A. Agonist
B. Antagonist
C. Inhibitor
D. Reuptake facilitator
🔴 RATIONALE: An agonist is a chemical substance that mimics or enhances the effects of a neurotransmitter. By blocking reuptake, the
medication increases the duration and concentration of serotonin available to bind to the postsynaptic receptors.
Question 3
During a neurosurgery procedure, a physician electrically stimulates a specific area of the patient's brain, causing the patient to report a
tingling sensation in their left index finger. Which region of the brain was most likely stimulated?
A. The right motor cortex
B. The left somatosensory cortex
🟢 C. The right somatosensory cortex
D. The left motor cortex
🔴 RATIONALE: The somatosensory cortex processing sensory inputs like touch is located in the parietal lobe. Because the brain's sensory
paths are contralateral, sensory sensations on the left side of the body are processed in the right hemisphere.
Question 4
A patient suffers a stroke and subsequently struggles to produce fluent speech, often speaking in short, fragmented phrases with great effort,
though they can understand spoken language perfectly. Damage most likely occurred in:
🟢 A. Broca's area
B. Wernicke's area
C. The basal ganglia
D. The occipital lobe
🔴 RATIONALE: Broca's area, located in the left frontal lobe, is responsible for speech production. Damage leads to expressive aphasia,
where speech production is impaired but comprehension remains largely intact.
Question 5
Which of the following research methods allows a psychologist to definitively establish a cause-and-effect relationship between two
variables?
A. Naturalistic observation
B. Correlational study
C. Case study
🟢 D. Controlled experiment
, 🔴 RATIONALE: Only controlled experiments allow researchers to establish causal relationships because they isolate the independent
variable through manipulation while controlling for confounding variables using random assignment.
Question 6
A student participates in a psychological study where they are asked to look at a bright red square for 60 seconds and then look at a blank
white wall. The student perceives a green square on the wall. This phenomenon is best explained by:
A. Trichromatic theory
🟢 B. Opponent-process theory
C. Place theory
D. Frequency theory
🔴 RATIONALE: The opponent-process theory states that color vision depends on pairs of opposing retinal processes (red-green, blue-
yellow, black-white). Fatiguing the red receptors leads to the perception of the opponent color, green, as an afterimage.
Question 7
Every time a train passes by a house, the windows rattle violently, which initially frightens a toddler. Over several weeks, the child begins to
cry as soon as they hear the distant whistle of the approaching train, before the rattling starts. The conditioned stimulus is the:
🟢 A. Train whistle
B. Windows rattling
C. Crying behavior
D. Fear response
🔴 RATIONALE: In classical conditioning, the conditioned stimulus is an initially neutral stimulus (the train whistle) that, after being paired
repeatedly with an unconditioned stimulus (the windows rattling), triggers a conditioned response.
Question 8
An individual who sustains damage to the hippocampus would most likely experience which of the following deficits?
A. Inability to regulate basic biological drives like hunger
B. Loss of fine motor coordination and balance
🟢 C. Inability to form new declarative memories
D. Alterations in visual perception and spatial processing
🔴 RATIONALE: The hippocampus is vital for consolidating new explicit or declarative memories into long-term storage. Damage prevents
the formation of new semantic or episodic memories, while procedural memory often remains intact.
Question 9
An employee receives a cash bonus for every five high-quality units they assemble on the factory line. This compensation system operates
on which schedule of reinforcement?
A. Fixed-interval
B. Variable-ratio
🟢 C. Fixed-ratio
D. Variable-interval
