How close are these to the real EPPP?
The EPPP Part 1 (Knowledge) is 225 items (175 scored, 50 pretest) over 4 hours 15 minutes, spanning eight
content domains from biological bases of behavior to ethics. The samples below reflect that mix.
Sample EPPP questions
- A child stops having tantrums after the parent begins removing a disliked chore whenever the
child stays calm. The calm behavior increases. This is an example of:- A. Positive reinforcement
- B. Negative reinforcement
- C. Positive punishment
- D. Negative punishment
Answer: B. A behavior increases (reinforcement) because an aversive stimulus — the
disliked chore — is removed (negative). Removing something to increase a behavior is negative
reinforcement, a classic distinction tested on the EPPP. - A researcher rejects the null hypothesis when it is actually true. This is:
- A. A Type II error
- B. A Type I error
- C. Adequate power
- D. A confound
Answer: B. Rejecting a true null hypothesis is a Type I (alpha) error — a false
positive. A Type II error (A) is failing to reject a false null. Research methods and statistics is a small
but high-precision EPPP domain. - A client tells a psychologist of a specific, credible plan to seriously harm a named third
party. Under Tarasoff principles, the psychologist’s duty is generally to:- A. Maintain confidentiality without exception
- B. Take reasonable steps to protect the
intended victim, which may include warning - C. Immediately terminate therapy
- D. Wait for the next session to reassess
Answer: B. The duty to protect can override confidentiality when there is a serious,
imminent threat to an identifiable victim; reasonable protective steps may include warning the victim and/or
notifying authorities. Ethics is one of the two largest EPPP domains. - According to Erikson, the central psychosocial crisis of adolescence is:
- A. Trust vs. mistrust
- B. Industry vs. inferiority
- C. Identity vs. role
confusion - D. Generativity vs. stagnation
Answer: C. Erikson placed identity vs. role confusion in adolescence. Industry vs.
inferiority (B) is school-age; generativity vs. stagnation (D) is middle adulthood. Lifespan development is
a core knowledge domain. - A test yields very similar scores when the same people take it two weeks apart. This describes
the test’s:- A. Content validity
- B. Test-retest reliability
- C. Predictive validity
- D. Internal consistency
Answer: B. Consistency of scores across time is test-retest reliability. Validity (A, C)
concerns whether the test measures or predicts what it should; internal consistency (D) concerns item
inter-correlation within one administration. Assessment is a major EPPP domain.
How did you do?
If conditioning, statistics, ethics, and development blurred together, that’s exactly what practice fixes.
