Study Guide Overview
This study guide covers trait theories of personality, focusing on key theorists like Allport, Eysenck, Myers-Briggs, Cattell, and Costa & McCrae. It explains major concepts such as the Big Five personality traits (OCEAN), cardinal, central, and secondary traits, and the use of factor analysis. It also compares trait theory with other personality perspectives (psychoanalytic, humanistic, social-cognitive) and provides practice questions and exam tips.
#AP Psychology: Trait Theories - Your Ultimate Study Guide ๐
Hey there, future AP Psych superstar! Let's dive into trait theories of personality. This guide is designed to be your go-to resource for a quick, effective review. We'll break down the key concepts, highlight what's most important, and get you feeling confident for the exam. Let's get started!
#Trait Theories: The Basics
Trait theorists believe that our personalities are made up of stable characteristics (traits) that influence how we behave. Think of it like this: if you're generally outgoing, that's a trait that tends to show up in different situations. They often emphasize that these traits are largely genetic ๐งฌ.
Trait theories are all about identifying and measuring consistent patterns of behavior. They assume that these patterns are relatively stable over time and across situations.
#Gordon Allport
Gordon Allport was a pioneer in trait theory. He focused on describing personality through individual traits, which he categorized as:
- Cardinal Traits: These are the dominant traits that define a person's entire life. Not everyone has a cardinal trait. Think of someone so driven by ambition that it shapes everything they do.
- Central Traits: These are the general characteristics that form the foundation of our personality, like being honest, kind, or outgoing. Most of us have several central traits.
Factor analysis is a statistical technique used to identify clusters of related traits. It helps simplify the complex world of personality into manageable dimensions.
Think of Allport as the "A" in "Analyzing" traits. He's all about breaking down personality into its core components.
#Hans Eysenck
Hans Eysenck took a nomothetic approach, believing that the same basic set of traits can describe everyone's personality. He focused on three key dimensions:
- Extroversion: How outgoing and sociable you are. Extroverts seek stimulation from the outside world, while introverts prefer quieter environments. ๐ฃ๏ธ
- Neuroticism: Your level of emotional stability or instability. High neuroticism means you're more prone to anxiety and mood swings. ๐ฌ
- Psychoticism: Measures your level of tough-mindedness and impulsivity. ๐
Eysenck's model is often visualized as a two-axis graph with introversion-extroversion on one axis and stability-instability on the other. This can be a helpful way to remember his theory.
Remember Eysenck with "E" for "Extroversion" and "Emotional Stability." He's all about those key dimensions.
#Isabel Myers and Katharine Briggs
These two developed the Myers-Briggs Type Indicator (MBTI), a popular personality test that categorizes people into 16 personality types based on four dichotomies:
- Favorite World:
- Extroverted (E): Outgoing, energetic, sociable. ๐
- Introverted (I): Gentle, quiet, caring, logical. ๐จ
- Information:
- Sensing (S): Organized, observant, focuses on concrete details. ๐ฐ
- Intuition (N): Logical, conceptual, insightful, focuses on patterns and possibilities. ๐ค
- Decisions:
- Feeling (F): Sensitive, appreciative, tactful, values personal concerns. โค๏ธ
- Thinking (T): Analytical, logical, values facts and objectivity. โ๏ธ
- Structure:
- Judging (J): Determined, concrete, prefers structure and planning. ๐ญ
- Perceiving (P): Independent, questioning, adaptable, prefers flexibility and spontaneity. ๐
While the MBTI is widely used, it's important to note that it's not as empirically validated as other trait theories. It's more of a fun tool for self-exploration than a scientifically rigorous measure of personality.
Think of Myers-Briggs as "MBTI" and remember that it's all about Many Branching Types of Individuals.
#Raymond Cattell
Raymond Cattell identified 16 personality factors using factor analysis. His 16PF questionnaire measures these traits. While you don't need to memorize all 16, it's good to know he aimed for a comprehensive approach.
Remember Cattell with "C" for "Comprehensive." He's all about covering all the bases with his 16 factors.
#Paul Costa and Robert McCrae
Costa and McCrae developed the Big Five personality traits, often remembered with the acronym OCEAN:
- Openness: How open you are to new experiences. ๐
- Low: Practical, prefers routine.
- High: Imaginative, prefers variety.
- Conscientiousness: How organized and careful you are. ๐งฎ
- Low: Disorganized, careless.
- High: Organized, careful, disciplined.
- Agreeableness: How well you get along with others. ๐
- Low: Ruthless, suspicious, uncooperative.
- High: Soft-hearted, trusting, helpful.
- Extroversion: How outgoing or shy you are. ๐ฃ๏ธ
- Low: Retiring, sober, reserved.
- High: Sociable, affectionate, fun-loving.
- Neuroticism: How anxious or calm you are. ๐ฌ
- Low: Calm, secure, self-satisfied.
- High: Anxious, insecure, self-pitying.
The Big Five is a cornerstone of modern personality psychology. It's crucial to understand each trait and how they manifest in behavior.
Use OCEAN to remember the Big Five: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.
#Comparing Personality Theories
Here's a quick table to compare different personality theories:
Personality Theory | Key Proponents | Assumptions | View of Personality |
---|---|---|---|
Psychoanalytic | Freud | Emotional disorders spring from unconscious dynamics, such as unresolved sexual and other childhood conflicts, and fixation at various developmental stages. Defense mechanisms fend off anxiety. | Personality consists of pleasure-seeking impulses (the id), a reality-oriented executive (the ego), and an internalized set of ideals (the superego). |
Psychodynamic | Adler, Horney, Jung | The unconscious and conscious minds interact. Childhood experiences and defense mechanisms are important. | The dynamic interplay of conscious and unconscious motives and conflicts shape our personality. |
Humanistic | Rogers, Maslow | Rather than examining the struggles of sick people, it's better to focus on the ways healthy people strive for self-realization. | If our basic human needs are met, people will strive toward self-actualization. In a climate of unconditional positive regard, we can develop self-awareness and a more realistic and positive self-concept. |
Trait | Allport, Eysenck, McCrae, Costa | We have certain stable and enduring characteristics, influenced by genetic predispositions. | Scientific study of traits has isolated important dimensions of personality, such as the Big Five traits. |
Social-Cognitive | Bandura | Our traits and the social context interact to produce our behaviors. | Conditioning and observational learning interact with cognition to create behavior patterns. |
Pay attention to the key differences between these theories. Questions often ask you to compare and contrast them.
#Final Exam Focus
Okay, let's get down to the nitty-gritty. Here's what to focus on for the exam:
- Big Five (OCEAN): This is HUGE. Know what each trait means and how it affects behavior. ๐ก
- Trait vs. Other Theories: Be ready to compare trait theories with psychoanalytic, humanistic, and social-cognitive perspectives.
- Factor Analysis: Understand how this statistical method is used to identify personality dimensions.
- Key Theorists: Know the main contributions of Allport, Eysenck, Cattell, Costa, and McCrae.
#Last-Minute Tips
- Time Management: Don't get bogged down on tough questions. Move on and come back if you have time.
- Common Pitfalls: Avoid overthinking. Stick to what you know and avoid making assumptions.
- FRQ Strategies: Always define key terms and apply them to the scenario. Use specific examples to support your points.

- 1 point for correctly identifying and describing Neuroticism (e.g., Sarah is anxious and worries a lot).
(B) (4 points)
- 2 points for explaining how a trait theorist would explain Sarah's anxiety (e.g., it's a stable trait, she's high in neuroticism).
- 2 points for explaining how a psychoanalytic theorist would explain Sarah's anxiety (e.g., it stems from unresolved unconscious conflicts, possibly related to childhood experiences).
(C) (2 points)
- 2 points for explaining how the MBTI might interpret Sarah's behavior differently (e.g., she might be a Judging type due to her organization, but also an Introvert due to her anxiety in social settings, or a Feeling type due to her politeness).
