Study Tips

  1. The exam uses DSM-5 terminology. Know the difference between major depressive disorder and bipolar disorder, and understand the classification of anxiety disorders, OCD, and PTSD.
  2. Social psychology (9–10%) is the single heaviest category. Know Milgram, Asch, Zimbardo, and the concepts of attribution, cognitive dissonance, and the bystander effect.
  3. Understand all major perspectives (behavioral, cognitive, psychodynamic, humanistic, biological, evolutionary, sociocultural) and be able to identify which one applies to a given scenario.
  4. Memory and learning are reliably tested. Know the difference between classical and operant conditioning, and be fluent with encoding, storage, and retrieval concepts.
  5. Don't underestimate developmental psychology. Know Piaget's stages, Erikson's crises, Kohlberg's levels, and Ainsworth's attachment types cold.

1. Wilhelm Wundt is considered the founder of modern psychology primarily because he
  • A) developed the first intelligence test
  • B) established the first psychology laboratory at the University of Leipzig in 1879
  • C) proposed the theory of the unconscious mind
  • D) invented the electroencephalogram
  • E) published the first textbook on behaviorism
View Answer & Explanation

Correct Answer:
B) established the first psychology laboratory at the University of Leipzig in 1879

Explanation:
Wilhelm Wundt opened the first formal psychology laboratory at the University of Leipzig in 1879, marking psychology's emergence as a discipline separate from philosophy. He used systematic experimental methods to study consciousness, which is why he is credited as the founder of modern psychology.

2. A psychologist who studies how natural selection has shaped human behavioral tendencies is most closely aligned with the
  • A) psychodynamic perspective
  • B) humanistic perspective
  • C) evolutionary perspective
  • D) behavioral perspective
  • E) structuralist perspective
View Answer & Explanation

Correct Answer:
C) evolutionary perspective

Explanation:
The evolutionary perspective applies principles of natural selection and adaptation to explain human psychological traits and behaviors. It argues that many behavioral tendencies evolved because they helped our ancestors survive and reproduce.

3. In an experiment, the variable that the researcher manipulates is the
  • A) dependent variable
  • B) confounding variable
  • C) independent variable
  • D) control variable
  • E) extraneous variable
View Answer & Explanation

Correct Answer:
C) independent variable

Explanation:
The independent variable (IV) is the factor that the experimenter deliberately manipulates to observe its effect on the dependent variable. The dependent variable is what is measured as the outcome.

4. A correlation coefficient of -0.85 between hours of sleep and number of errors on a task indicates
  • A) a weak positive relationship
  • B) no relationship between the variables
  • C) a strong negative relationship: as sleep increases, errors tend to decrease
  • D) that sleep deprivation causes errors
  • E) a strong positive relationship
View Answer & Explanation

Correct Answer:
C) a strong negative relationship: as sleep increases, errors tend to decrease

Explanation:
A correlation of -0.85 indicates a strong negative relationship. As one variable increases, the other tends to decrease. However, correlation does not establish causation — an experiment would be needed to determine whether sleep deprivation directly causes more errors.

5. Random assignment in experimental research is used primarily to
  • A) ensure that the sample is representative of the population
  • B) increase the sample size
  • C) equalize participant characteristics across experimental and control groups
  • D) eliminate the need for a control group
  • E) reduce the number of confounding variables that must be measured
View Answer & Explanation

Correct Answer:
C) equalize participant characteristics across experimental and control groups

Explanation:
Random assignment distributes participant characteristics (age, personality, etc.) roughly equally across conditions, reducing the likelihood that pre-existing differences between groups — rather than the independent variable — account for differences in the dependent variable.
