Self-Expression Theory: Test Your Personality Undertone

1. Theoretical Basis: Self-Expression and Personality Psychology

This test is based on the 'Self-Expression Theory' in psychology and the Extraversion dimension of the 'Big Five Personality Traits' model, combined with Carl Jung's classic accounts of introversion and extraversion in his psychological types. Self-expression is not just social behavior but the natural revelation of personality traits - how you express yourself in different settings (volume, pace, initiative, and so on) often reveals your personality undertone.

Core theoretical references:

• Hans Eysenck's personality theory: Treats extraversion as a core personality dimension, holding that extraverts need more external stimulation and are more inclined to express themselves through words and action.
• Mark Leary's self-presentation theory: People deliberately or unwittingly adjust how they express themselves in social life to fit the environment and convey their self-concept.
• Psychosocial rhythm theory: An individual's expression pattern is closely tied to inner emotion regulation and social rhythm, reflecting deep personality dynamics.

This test is not a simple copy of any original scale but a redesigned, culturally adapted self-assessment tool built on the theoretical core above, helping you understand your expression tendencies and personality undertone.

2. What Is a 'Personality Undertone'?

'Personality undertone' is a metaphorical concept for an individual's most core, most stable personality tendencies in their natural state. Like the base coat in a painting, it may not show directly, yet it shapes how all the upper layers of color express themselves. The personality undertone usually has three layers:

• Expressive energy: In social life, do you tend to actively radiate energy or quietly take it in?
• Emotional transparency: Are you used to showing emotions outwardly or processing them inwardly?
• Interaction stance: Do you prefer to lead exchanges, or are you better at responding and cooperating?

3. The Four Core Dimensions of This Test

Building on the theory above, this test assesses your self-expression tendencies across four dimensions, 15 questions in total:

• Expression Initiative: In conversation, are you used to starting topics or waiting for others to begin?
• Emotional Expressiveness: Are your emotions and attitudes easy for others to detect?
• Social Comfort Zone: How much your expression changes across settings, reflecting social adaptability.
• Expression Rhythm Preference: Do you like fast, lively interaction, or a calm, gentle rhythm?

4. Purpose of the Test and Who It Is For

This test aims to help you:

• Understand your self-expression tendencies and character core
• Identify your natural patterns and latent strengths in social life
• Discover how your expression shifts across situations
• Gain a reference perspective for personal growth, career choices, and relationships

Especially suited to people interested in self-knowledge, hoping to communicate more effectively, or in the midst of exploring their social roles.

5. Scoring Method

Each question uses 5-point scoring, from 'strongly disagree' to 'strongly agree'. Based on your score combination across the four dimensions, the system sorts personality undertones into four typical types:the blazing warm tone, the bright clear tone, the serene cool tone, and the deep dark tone. Each type has its own distinctive expression style and growth advice.
