seven original practice questions designed to help with EPPP preparation on Validity Concepts in Psychological Research.

Ethical and legal questions on the EPPP can be challenging because several answers may appear reasonable, but only one represents the best professional response. This episode examines confidentiality, informed consent, mandated reporting, professional boundaries, and the difference between ethical obligations and legal requirements. Through clinical scenarios and a practical decision-making sequence, listeners will learn how to identify the most appropriate first action when facing difficult ethical dilemmas.

When does a psychologist have a legal or ethical obligation to disclose confidential information? This episode examines three important EPPP concepts: duty to warn, duty to protect, and mandatory reporting. Through clinical scenarios involving threats of violence, suspected child abuse, and suicidal patients, listeners will learn how to distinguish ethical responsibilities from legal requirements. Particular attention is given to the decision-making process and the types of questions commonly encountered on the EPPP.

A psychological test can have 90% sensitivity and specificity and still produce more false positives than true positives. This episode examines the base rate fallacy, why psychologists sometimes overestimate diagnostic accuracy, and how Bayesian reasoning improves clinical judgment. We also explore how the same statistical error affects forensic risk assessments and why the human brain struggles with probability.

What is the difference between a Type I error and a Type II error, and why does it matter on the EPPP? In this episode, we break down false positives, false negatives, statistical significance, alpha levels, beta, and statistical power using straightforward examples. Learn how to identify each error, understand the relationship between them, and avoid common mistakes on the psychology licensing exam.

The EPPP does not require you to become a neuroanatomist, but it does expect you to recognize the major dopamine pathways and what happens when dopamine activity changes within them. This episode simplifies the mesolimbic, mesocortical, nigrostriatal, and tuberoinfundibular pathways by connecting each one to the symptoms and medication side effects most likely to appear on the exam. By the end, you should be able to work backward from a clinical vignette and identify the dopamine pathway being tested.
