D564: Theories of Personality

A guide to WGU's undergraduate psychology course comparing the major theories of personality and the research behind them.

Updated October 2026 · 5 min read

D564 Theories of Personality is a course in WGU's Bachelor of Science in Psychology. WGU describes it as covering the concepts and assumptions of significant personality theories, assessing their strengths and weaknesses, and the research methods used to study personality.

Students find it demanding because several theories seem to explain the same behavior in very different ways. The skill being assessed is comparison: knowing what each lens assumes, what evidence supports it and where it falls short.

What D564 Covers

Competency (summarized)In practice
Recognize considerations in the study of personalityResearch methods, definitions and the role of culture
Key concepts of the psychodynamic lensUnconscious processes, early experience, defense mechanisms
Key concepts of the humanistic perspectiveSelf-actualisation, personal growth, the self

WGU adds that cultural impacts on personality are discussed throughout.

Key Concepts Explained

Describing Versus Explaining

Trait theories describe how people differ, often using broad dimensions. Other theories try to explain why. Keep that difference in mind when a question asks what a theory "predicts".

Example: A student avoids public speaking. A trait view might describe low extraversion. A social-cognitive view might point to low self-efficacy in speaking. A psychodynamic view might explore anxiety rooted in early experience. Each lens asks a different question about the same behavior.

Evaluating a Theory

Strengths and weaknesses are assessed on evidence, testability and scope. A theory that is hard to test, or that explains everything after the fact, is weaker scientifically even if it is influential.

Culture and Personality

Many theories were developed with limited samples. Ask whether the concepts apply across cultures or reflect one context, and say so when you evaluate them.

Typical Assignments and How to Approach Them

TaskWhat it testsHow to approach it
Compare two or more theoriesAccurate understanding and critiqueUse a table of assumptions, evidence and limits first
Apply a theory to a caseUsing concepts correctlyQuote the behavior, name the concept, explain the link
Research methods questionHow personality is studiedMatch method to question and note limitations

Check your course page for the assessment format used in your version.

Writing a Strong Theory Comparison

A reliable structure has four parts. First, state the question you are answering. Second, summarize each theory's central assumption in one or two sentences. Third, compare them on specific points such as the role of the unconscious, free will, early experience and evidence. Fourth, conclude with which theory fits your case best and why.

Use the course materials for definitions and cite them as your rubric or instructor requires. Keep the writing in your own words and apply each concept to a concrete person or scenario rather than describing it in the abstract.

The Lenses Side by Side

A comparison grid is the single most useful study tool for this course. The wording below summarizes the general ideas; use your course readings for the exact terms your assessment expects.

LensCore ideaStrength and criticism
PsychodynamicUnconscious processes and early experience shape personalityHighlights hidden motives; hard to test scientifically
HumanisticPeople seek growth and self-understandingValues the whole person; concepts are hard to measure
Social-cognitiveBeliefs and observed behavior interact with situationsTestable, accounts for context; may underplay stable differences
TraitStable dimensions describe differences between peopleMeasurable and predictive; describes more than it explains
Biological and behavioralHeredity, brain function and reinforcementStrong research base; can neglect meaning and choice

Fill in the last two columns yourself from the readings. Doing so forces you to engage with the evidence rather than copy a summary, and it gives you ready material for a critique paragraph.

Research Methods in Personality

The first competency asks about considerations in studying personality. Think about self-report questionnaires, which are convenient but depend on honesty and insight, and observation or case study, which give depth but limit generalization. Always say what a method can and cannot show.
