Personality Course
Understand what drives human behaviour at its core with a rigorous, science-backed exploration of personality psychology. From foundational trait models to applied assessment and clinical patterns, this course provides the knowledge and tools that professionals rely on. Whether you work in HR, coaching, therapy, or leadership, you'll walk away with skills you can use immediately.
What you will learn:
This course covers the landscape of personality science, from historical theories and biological foundations to assessment methods and applied practice. You will study the Big Five and alternative trait taxonomies, psychodynamic and cognitive frameworks, and the neurobiological bases of individual differences. You will learn to select and interpret validated personality assessments and recognise disorder patterns in clinical and organisational contexts. The curriculum also addresses personality change, cross-cultural issues, emotional intelligence, and the growing role of technology in measurement. By the end, you will be equipped to apply personality science in coaching, personnel selection, team development, and clinical case formulation.

Foundations of Personality Psychology
Lesson 1 • Defining Personality and Its Scope
Clarifies what personality is, how it differs from mood and behavior, and why it matters professionally. Anchors all subsequent theory in a shared definition.
Lesson 2 • Core Theoretical Perspectives Overview
Surveys psychodynamic, humanistic, behavioral, and trait perspectives at a high level. Prepares students to evaluate each tradition in depth later.
Lesson 3 • Historical Roots of Personality Theory
Traces personality study from ancient typologies to modern empirical science. Provides context for understanding why competing theories exist.
Lesson 4 • Personality Across the Lifespan
Examines how personality forms, stabilizes, and changes from childhood through adulthood. Connects developmental milestones to professional assessment contexts.
Chapter 2HideHide detailsSee detailsMajor Trait Models and Taxonomies
Major Trait Models and Taxonomies
Lesson 1 • Trait Stability and Change Over Time
Examines longitudinal evidence on trait consistency and malleability. Connects stability research to realistic expectations in coaching and development.
Lesson 2 • The Big Five Factor Model
Introduces the five-factor structure as the field's dominant taxonomy. Students learn each dimension's meaning, facets, and predictive value.
Lesson 3 • Cross-Cultural Validity of Trait Models
Evaluates how well Western-derived trait models replicate across cultures. Students learn to apply and adapt frameworks in diverse professional settings.
Lesson 4 • Facets, Nuances, and Narrow Traits
Moves below broad factors to examine specific facets and narrow traits that improve prediction. Demonstrates how granularity increases applied accuracy.
Lesson 5 • Alternative Trait Taxonomies
Compares HEXACO, three-factor models, and other competing frameworks to the Big Five. Students evaluate when alternative models offer superior explanatory power.
Chapter 3HideHide detailsSee detailsBiological and Genetic Bases of Personality
Biological and Genetic Bases of Personality
Lesson 1 • Hormones, Neurotransmitters, and Personality
Explores how cortisol, dopamine, serotonin, and testosterone relate to trait expression. Provides a biochemical layer for understanding individual differences.
Lesson 2 • Neurobiological Systems and Traits
Maps major brain systems—reward, threat, inhibition—onto personality dimensions. Students link neuroscience findings to observable trait differences.
Lesson 3 • Temperament as Biological Personality
Defines temperament as the early-appearing biological substrate of personality. Traces how infant temperament predicts adult trait profiles.
Lesson 4 • Heritability of Personality Traits
Reviews twin, adoption, and molecular genetics studies estimating trait heritability. Establishes the genetic floor beneath environmental influences.
Chapter 4HideHide detailsSee detailsPsychodynamic and Depth Perspectives
Psychodynamic and Depth Perspectives
Lesson 1 • Defence Mechanisms and Coping Styles
Catalogues major defences from primitive to mature and links them to personality patterns. Students identify defences in case material and professional contexts.
Lesson 2 • Freudian Structural and Topographic Models
Covers id, ego, superego, and the conscious-unconscious continuum. Establishes the vocabulary for all subsequent psychodynamic discussion.
Lesson 3 • Object Relations and Attachment Theory
Introduces internalised representations of self and others as personality organisers. Connects early relational patterns to adult interpersonal functioning.
Lesson 4 • Neo-Freudian and Analytic Extensions
Examines Adler, Jung, Horney, and Erikson's departures from classical theory. Broadens the psychodynamic lens beyond drive theory.
Lesson 5 • Empirical Status of Psychodynamic Concepts
Evaluates research support for unconscious processes, defences, and attachment constructs. Teaches critical appraisal of depth psychology claims.
Chapter 5HideHide detailsSee detailsHumanistic, Cognitive, and Social-Cognitive Theories
Humanistic, Cognitive, and Social-Cognitive Theories
Lesson 1 • Locus of Control and Attributional Style
Covers internal-external control beliefs and explanatory style as stable personality variables. Links these constructs to motivation, resilience, and performance.
Lesson 2 • Personal Constructs and Cognitive Schemas
Examines Kelly's construct theory and Beck's schema model as personality organisers. Shows how cognitive structures filter experience and drive behaviour.
Lesson 3 • Maslow, Rogers, and Self-Actualisation
Covers the hierarchy of needs, unconditional positive regard, and the fully functioning person. Grounds humanistic applications in coaching and development.
Lesson 4 • Integrating Humanistic and Cognitive Views
Synthesises person-centred values with cognitive precision for applied personality work. Prepares students to blend frameworks in coaching and assessment.
Lesson 5 • Bandura's Social-Cognitive Framework
Introduces self-efficacy, observational learning, and reciprocal determinism as personality mechanisms. Directly applicable to behaviour change and training design.
Chapter 6HideHide detailsSee detailsPersonality Assessment Methods and Tools
Personality Assessment Methods and Tools
Lesson 1 • Psychometric Foundations of Assessment
Covers reliability, validity, standardisation, and norms as quality criteria. Provides the evaluative lens applied to every instrument in this chapter.
Lesson 2 • Ethical and Practical Assessment Standards
Addresses informed consent, confidentiality, feedback delivery, and appropriate tool use. Ensures students practise assessment within professional and ethical boundaries.
Lesson 3 • Projective and Performance-Based Methods
Introduces inkblot, apperception, and sentence-completion techniques and their evidence base. Balances clinical utility against psychometric limitations.
Lesson 4 • Self-Report Inventories and Questionnaires
Examines widely used trait inventories, their scales, and response formats. Students practise profile interpretation and identify response bias risks.
Lesson 5 • Observer Ratings and Behavioural Assessment
Covers peer ratings, 360-degree feedback, and behavioural observation as personality data sources. Demonstrates how multi-method data improves accuracy.
Chapter 7HideHide detailsSee detailsPersonality Disorders and Maladaptive Patterns
Personality Disorders and Maladaptive Patterns
Lesson 1 • Cluster A: Odd and Eccentric Patterns
Covers paranoid, schizoid, and schizotypal presentations and their trait underpinnings. Students learn recognition cues and functional impact in non-clinical settings.
Lesson 2 • Dimensional Alternatives and the Dark Triad
Introduces the alternative dimensional model and subclinical dark triad traits. Prepares students to assess personality risk in leadership and team contexts.
Lesson 3 • Cluster B: Dramatic and Erratic Patterns
Examines antisocial, borderline, histrionic, and narcissistic presentations. Focuses on interpersonal impact and recognition in organisational contexts.
Lesson 4 • Cluster C: Anxious and Fearful Patterns
Covers avoidant, dependent, and obsessive-compulsive presentations and their anxiety roots. Links these patterns to performance and relationship difficulties.
Lesson 5 • Conceptualising Personality Pathology
Defines personality disorder as extreme, inflexible trait expression causing impairment. Contrasts categorical and dimensional diagnostic approaches.
Chapter 8HideHide detailsSee detailsApplied Personality Science in Professional Contexts

Lesson 5 • Personality-Based Coaching and Development
Applies trait and schema models to individual coaching and leadership development. Students build feedback and goal-setting processes grounded in personality data.
