This document outlines a 3-part discussion assignment on developmental theories. Part 1 asks students to summarize Freud's psychosexual theory, justify the importance of the first 6 years, and support their response with scholarly sources. Part 2 requires students to provide examples of classical conditioning in their own lives, explain how systematic desensitization could help a child, and discuss an instance where punishment did not change their behavior. Part 3 instructs students to design an experimental study related to human development, addressing research problems, variables, hypotheses, methods, populations, procedures, potential results, and bias minimization.
