Question 1: Who is widely regarded as the founder of psychology as a formal
scientific discipline?
A. Sigmund Freud
B. B.F. Skinner
C. Wilhelm Wundt
D. William James
CORRECT ANSWER: C. Wilhelm Wundt
RATIONALE:Wilhelm Wundt established the first psychology laboratory in Leipzig,
Germany, in 1879, which is traditionally cited as the beginning of psychology as an
independent experimental science. While Freud, Skinner, and James made significant
contributions, Wundt's founding of the lab marks the formal inception of psychology as
a distinct field.
Question 2: In an experimental study, the variable that the researcher manipulates
is called the:
A. Dependent variable
B. Control variable
C. Extraneous variable
D. Independent variable
CORRECT ANSWER: D. Independent variable
RATIONALE:The independent variable is the condition or factor that the experimenter
deliberately changes to observe its effect on the dependent variable. The dependent
variable is the outcome measured, control variables are held constant, and extraneous
variables are unwanted factors that could influence results.
Question 3: Which psychological perspective emphasizes the role of unconscious
conflicts and early childhood experiences in shaping behavior?
A. Behavioral
B. Humanistic
C. Psychodynamic
D. Cognitive
CORRECT ANSWER: C. Psychodynamic
,RATIONALE:The psychodynamic perspective, founded by Sigmund Freud, focuses on
unconscious drives, internal conflicts, and the influence of early life experiences on
personality and behavior. Behavioral psychology emphasizes observable actions,
humanistic focuses on growth potential, and cognitive examines mental processes.
Question 4: The branch of psychology that studies how people think, learn,
remember, and solve problems is known as:
A. Social psychology
B. Developmental psychology
C. Cognitive psychology
D. Clinical psychology
CORRECT ANSWER: C. Cognitive psychology
RATIONALE:Cognitive psychology is dedicated to understanding mental processes
such as perception, memory, language, problem-solving, and decision-making. Social
psychology examines interpersonal interactions, developmental psychology studies
changes across the lifespan, and clinical psychology focuses on diagnosing and treating
mental disorders.
Question 5: Which research method involves observing behavior in its natural
environment without interference?
A. Case study
B. Survey
C. Naturalistic observation
D. Experiment
CORRECT ANSWER: C. Naturalistic observation
RATIONALE:Naturalistic observation is a descriptive research method where behavior
is systematically observed and recorded in real-world settings without manipulation.
Case studies focus on in-depth analysis of individuals or groups, surveys collect self-
reported data, and experiments involve controlled manipulation of variables.
Question 6: The smallest detectable difference between two stimuli that a person
can perceive 50% of the time is called the:
A. Absolute threshold
B. Just noticeable difference
C. Sensory adaptation
D. Signal detection
CORRECT ANSWER: B. Just noticeable difference
RATIONALE:The just noticeable difference (JND), also known as the difference
threshold, is the minimum change in a stimulus that can be detected half the time. The
absolute threshold is the minimum intensity needed to detect a stimulus, sensory
,adaptation is reduced sensitivity to constant stimulation, and signal detection theory
examines decision-making under uncertainty.
Question 7: In classical conditioning, the learned response to a previously neutral
stimulus is called the:
A. Unconditioned stimulus
B. Conditioned stimulus
C. Unconditioned response
D. Conditioned response
CORRECT ANSWER: D. Conditioned response
RATIONALE:In classical conditioning, the conditioned response (CR) is the learned
reaction to a conditioned stimulus (CS) after pairing with an unconditioned stimulus
(US). The unconditioned response (UR) is the natural, unlearned reaction to the US. The
CS was initially neutral but gains the ability to elicit the CR through association.
Question 8: Which part of the neuron receives messages from other neurons?
A. Axon
B. Myelin sheath
C. Dendrite
D. Terminal button
CORRECT ANSWER: C. Dendrite
RATIONALE:Dendrites are branched extensions of a neuron that receive
electrochemical signals from other neurons and transmit them toward the cell body.
Axons carry signals away from the cell body, the myelin sheath insulates axons to speed
transmission, and terminal buttons release neurotransmitters at synapses.
Question 9: According to Piaget, the stage of cognitive development characterized
by the ability to think logically about concrete events is:
A. Sensorimotor
B. Preoperational
C. Concrete operational
D. Formal operational
CORRECT ANSWER: C. Concrete operational
RATIONALE:Piaget's concrete operational stage (ages 7-11) involves logical thought
about tangible objects and events, including understanding conservation and
reversibility. Sensorimotor (birth-2) focuses on sensory experiences, preoperational (2-
7) features symbolic thought but egocentrism, and formal operational (12+) enables
abstract reasoning.
Question 10: The tendency to remember the first and last items in a list better than
the middle items is known as the:
, A. Spacing effect
B. Serial position effect
C. Context-dependent memory
D. Misinformation effect
CORRECT ANSWER: B. Serial position effect
RATIONALE:The serial position effect describes enhanced recall for items at the
beginning (primacy effect) and end (recency effect) of a sequence. The spacing effect
refers to better retention with distributed practice, context-dependent memory involves
retrieval cues matching encoding context, and the misinformation effect occurs when
misleading information distorts memory.
Question 11: Which neurotransmitter is most closely associated with feelings of
pleasure and reward?
A. Serotonin
B. Dopamine
C. GABA
D. Acetylcholine
CORRECT ANSWER: B. Dopamine
RATIONALE:Dopamine plays a key role in the brain's reward system, reinforcing
behaviors by producing feelings of pleasure and motivation. Serotonin regulates mood
and sleep, GABA is inhibitory and reduces neural activity, and acetylcholine is involved
in muscle activation and memory.
Question 12: In Maslow's hierarchy of needs, the highest level of motivation is:
A. Safety needs
B. Esteem needs
C. Self-actualization
D. Belongingness needs
CORRECT ANSWER: C. Self-actualization
RATIONALE:Maslow's hierarchy posits that self-actualization—the realization of one's
full potential—is the pinnacle of human motivation, achieved only after lower-level
needs (physiological, safety, love/belonging, esteem) are reasonably satisfied. This
reflects humanistic psychology's emphasis on growth and fulfillment.
Question 13: Which personality theory emphasizes the influence of unconscious
processes and childhood experiences?
A. Trait theory
B. Humanistic theory
C. Psychodynamic theory
D. Social-cognitive theory
