PSY 102 Exam 1 V3 | PSY 102 General Psychology | Actual Q&A with
Rationale (PSY102 Exam 1) | Grand Canyon University
1. Which subfield of psychology focuses on the scientific study of how people’s thoughts,
feelings, and behaviors are influenced by the actual, imagined, or implied presence of others?
A. Clinical Psychology
B. Social Psychology
C. Cognitive Psychology
D. Developmental Psychology
Answer: B
Rationale: Social psychology examines the impact of social environments on individual
behavior and cognition. It explores concepts such as conformity, persuasion, and group
dynamics. Understanding these influences helps psychologists explain why individuals act
differently in social settings compared to when they are alone.
2. In a research study, the factor that is manipulated by the researcher to determine its effect
on another variable is known as the:
A. Dependent variable
B. Independent variable
C. Control variable
D. Confounding variable
Answer: B
Rationale: The independent variable is the experimental factor that is changed or
controlled in a scientific study. By manipulating this variable, researchers can observe
changes in the dependent variable to establish a cause-and-effect relationship. It is the
‘cause’ part of the experiment’s causal hypothesis.
3. Which school of thought in psychology, led by Edward Titchener, used introspection to
explore the elemental structure of the human mind?
A. Functionalism
B. Structuralism
C. Behaviorism
D. Gestalt Psychology
Answer: B
,Rationale: Structuralism aimed to break down conscious experience into its basic
components using introspection. This method required participants to report their sensory
experiences in detail while performing tasks. While it laid the groundwork for
experimental psychology, it was later criticized for being too subjective.
4. Which part of the neuron is responsible for receiving signals from other neurons and
conducting them toward the cell body?
A. Axon
B. Myelin sheath
C. Dendrites
D. Terminal buttons
Answer: C
Rationale: Dendrites are the branching extensions of a neuron that receive chemical
messages from adjacent neurons. These messages are converted into electrical impulses
and sent toward the soma, or cell body. The number and complexity of dendrites determine
how much information a neuron can process.
5. The ‘all-or-none’ response refers to which of the following processes in a neuron?
A. The reuptake of neurotransmitters
B. The synthesis of myelin
C. The firing of an action potential
D. The transmission across the synapse
Answer: C
Rationale: An action potential either occurs fully or does not occur at all; there is no such
thing as a partial firing. If the electrical stimulation reaching the neuron exceeds a certain
threshold, the neuron fires down the length of the axon. This consistency ensures that the
neural signal remains clear and strong as it travels.
6. Which part of the brain is primarily responsible for coordinating movement and balance,
often referred to as the ‘little brain’?
A. Hypothalamus
B. Cerebellum
C. Amygdala
D. Thalamus
Answer: B
, Rationale: The cerebellum is located at the back of the brain and plays a crucial role in
motor control. It helps fine-tune movements, maintain posture, and supports procedural
memory like riding a bike. Damage to this area can result in difficulties with coordination
and fine motor skills.
7. The sympathetic nervous system is responsible for which physiological response?
A. Fight or flight
B. Rest and digest
C. Memory consolidation
D. Visual processing
Answer: A
Rationale: The sympathetic nervous system activates during periods of stress or perceived
threat. It increases heart rate, dilates pupils, and diverts blood flow to muscles to prepare
the body for action. This is the biological foundation of the acute stress response known as
fight-or-flight.
8. Which lobe of the cerebral cortex is primarily responsible for processing auditory
information?
A. Temporal lobe
B. Occipital lobe
C. Parietal lobe
D. Frontal lobe
Answer: A
Rationale: The temporal lobes are located near the ears and contain the primary auditory
cortex. They are involved in hearing, language comprehension, and some aspects of
memory. Specifically, Wernicke’s area, which is essential for understanding speech, is
usually found in the left temporal lobe.
9. In classical conditioning, the stimulus that naturally and automatically triggers a response
without prior learning is the:
A. Conditioned stimulus
B. Neutral stimulus
C. Unconditioned stimulus
D. Reinforcer
Answer: C
