SECTION 1: FOUNDATIONS OF PSYCHOLOGY
Questions 1–20
Major topics: Evolution of Psychology • Psychological Research • Major Schools of Thought •
Research Methods • Ethics • Scientific Reasoning
1. Which description most accurately defines psychology?
A) The scientific study of mind and behavior
B) The philosophical study of morality and consciousness
C) The medical treatment of neurological disease
D) The measurement of intelligence alone
Correct Answer: The scientific study of mind and behavior
Rationale: Psychology is the scientific study of mind and behavior. The discipline uses
systematic observation, measurement, experimentation, and other scientific methods to
understand thoughts, emotions, and actions. It is broader than medicine or philosophy
because psychologists investigate behavior and mental processes using empirical methods
across many contexts.
2. What was a major contribution of Wilhelm Wundt to psychology?
A) Developing psychoanalysis
B) Establishing one of the first experimental psychology laboratories
C) Creating the hierarchy of needs
D) Developing operant conditioning
Correct Answer: Establishing one of the first experimental psychology laboratories
,Rationale: Wilhelm Wundt is closely associated with establishing the first formal laboratory
devoted to experimental psychology in Leipzig in 1879. His work helped separate psychology
from philosophy and establish it as an experimental discipline. Psychoanalysis is associated
with Freud, hierarchy of needs with Maslow, and operant conditioning with Skinner.
3. According to functionalism, psychological processes are primarily understood by
examining their:
A) Unconscious conflicts
B) Basic sensory elements
C) Adaptive purposes
D) Observable reflexes
Correct Answer: Adaptive purposes
Rationale: Functionalism examines how mental processes and behaviors help organisms
adapt to their environments. William James was an important functionalist thinker.
Structuralism instead emphasized the components of conscious experience, while
psychodynamic approaches emphasize unconscious processes and behaviorism emphasizes
observable behavior.
4. Which theorist is most strongly associated with psychoanalytic theory?
A) Abraham Maslow
B) B. F. Skinner
C) John B. Watson
D) Sigmund Freud
Correct Answer: Sigmund Freud
Rationale: Sigmund Freud developed psychoanalytic theory, emphasizing unconscious
processes, early experiences, internal conflict, and personality dynamics. Freud's approach
differed from behaviorism, which focused on observable behavior, and humanism, which
emphasized growth and personal potential. His work strongly influenced clinical psychology
and theories of personality.
5. A researcher wants to understand how people behave in a natural setting without
manipulating variables. Which method is most appropriate?
A) Naturalistic observation
B) Laboratory experiment
C) Randomized clinical trial
,D) Double-blind experiment
Correct Answer: Naturalistic observation
Rationale: Naturalistic observation involves systematically observing behavior in its usual
environment without deliberately manipulating the situation. It can provide ecologically
meaningful information about behavior. However, because researchers do not control
variables, naturalistic observation cannot establish causal relationships as effectively as a
controlled experiment.
6. What is the primary purpose of a hypothesis in psychological research?
A) To guarantee the research outcome
B) To provide a testable prediction
C) To eliminate the need for data collection
D) To replace the research question
Correct Answer: To provide a testable prediction
Rationale: A hypothesis is a specific, testable prediction about relationships between
variables or expected outcomes. Researchers collect and analyze evidence to determine
whether their findings support the hypothesis. A hypothesis does not guarantee an outcome,
and it does not eliminate the need for systematic data collection.
7. When researchers report a correlation of +0.82 between two variables, what does this
indicate?
A) One variable definitely causes the other
B) There is no relationship between the variables
C) The variables have a strong positive relationship
D) The variables have a strong negative relationship
Correct Answer: The variables have a strong positive relationship
Rationale: A correlation coefficient ranges from −1.00 to +1.00. A value of +0.82 indicates a
strong positive association, meaning higher values of one variable tend to accompany higher
values of the other. Correlation alone does not establish causation because other variables
may explain the relationship.
8. Which feature distinguishes an experiment from a correlational study?
A) Experiments require participants to be adults
B) Experiments always use surveys
, C) Experiments cannot include control groups
D) Experiments manipulate an independent variable
Correct Answer: Experiments manipulate an independent variable
Rationale: The defining feature of an experiment is deliberate manipulation of an
independent variable while measuring its effect on a dependent variable. Researchers often
use control procedures and random assignment to reduce alternative explanations.
Correlational research measures naturally occurring relationships without experimentally
manipulating variables.
9. Why is random assignment important in an experiment?
A) It helps create comparable groups before treatment
B) It guarantees statistically significant findings
C) It eliminates the need for informed consent
D) It ensures every participant receives treatment
Correct Answer: It helps create comparable groups before treatment
Rationale: Random assignment gives participants an equal chance of entering different
experimental groups. This helps distribute individual differences across groups and reduces
systematic preexisting differences. Random assignment does not guarantee significant
findings, eliminate ethical requirements, or ensure that everyone receives the experimental
treatment.
10. What is the main purpose of informed consent in psychological research?
A) To guarantee that participants benefit financially
B) To allow participants to understand relevant research information before agreeing
C) To prevent researchers from analyzing results
D) To ensure that participants cannot withdraw
Correct Answer: To allow participants to understand relevant research information before
agreeing
Rationale: Informed consent requires participants to receive sufficient information about
relevant aspects of a study before voluntarily agreeing to participate. Ethical research also
protects participants from unnecessary harm and generally permits withdrawal. Consent
protects autonomy rather than guaranteeing financial benefit or preventing researchers
from analyzing data.
11. Which school of thought emphasized the study of observable behavior?
