💡 Why I Joined
After marriage, my husband and I naturally noticed our differences, yet we didn’t always understand why. As we prepare to raise our child together, I felt it was important to first understand our inborn temperaments and personalities. That’s why I joined this special lecture as part of my ongoing project, Being a Good Wife and Parent.
📘 What is the TCI Personality Test?
The TCI (Temperament and Character Inventory) is a personality theory developed by the American psychologist Cloninger, designed to assess both the temperament—the innate foundation of one’s emotions and behavior—and the character, which develops through experience and environment over time.
The TCI consists of seven main dimensions:
-
Four temperament categories represent inborn tendencies,
-
Three character categories reflect traits developed through life experiences.
Results are presented as percentile graphs, interpreted as follows:
-
Below 30: Low
-
30–70: Average range
-
Above 70: High
🧬 Ⅰ. The Four Temperaments (Temperament)
1️⃣ Novelty Seeking
This dimension relates to behavioral activation, describing one’s energy and desire to explore and make life more exciting.
-
High: Curious, easily bored, has many interests, and can become irritated quickly.
-
Low: Calm, rarely irritated, and generally stable.
Subscales:
-
Conventionality vs Exploratory Excitability – Tolerance for boredom and interest in new stimuli
-
Thoughtfulness vs Impulsiveness – Degree of deliberation before acting
-
Self-Control vs Extravagance – How one manages resources such as time, money, and energy
-
Orderliness vs Disorderliness – Preference for rules and structure vs independence and stubbornness
2️⃣ Harm Avoidance
This trait is related to behavioral inhibition, reflecting one’s tendency to avoid danger, anxiety, or fear.
-
High: Cautious, anxious, and often worried
-
Low: Bold, fearless, and comfortable in unfamiliar situations
Subscales:
-
Optimism vs Anticipatory Worry – Carefree “go-with-the-flow” type vs cautious planner
-
Fear of Uncertainty – Fear of unfamiliar experiences
-
Shyness with Strangers – Level of social inhibition
-
Energetic vs Easily Fatigued – Speed of energy recovery and fatigue level
3️⃣ Reward Dependence
This dimension concerns behavioral maintenance—how much one’s behavior depends on social approval and emotional feedback from others.
-
High: Sensitive to others’ reactions, often feels loneliness, guilt, or empathy
-
Low: Independent and less influenced by others’ opinions
Subscales:
-
Emotional Sensitivity – Ability to perceive and empathize with others’ emotions
-
Emotional Openness – Willingness to express and share one’s feelings
-
Detached vs Warm – Preference for time spent with others
-
Independence vs Dependence – Reliance on others’ feedback vs self-driven judgment
4️⃣ Persistence
Another factor related to behavioral maintenance, reflecting the power to persevere and achieve goals.
-
High: Persistent, goal-oriented, hardworking, and often recognized for reliability
-
Low: Easygoing and less discouraged by temporary failure (“I’ll do better next time”)
Subscales:
-
Industriousness – Ability to start tasks diligently
-
Perseverance – Ability to finish what one starts
-
Ambition for Achievement – Level of challenge and aspiration one sets for goals
-
Perfectionism – Striving to avoid mistakes and pursue precision
🌱 Ⅱ. The Three Characters (Character)
While temperament represents inborn tendencies, character develops through life experiences and environment.
It reflects one’s self-understanding, adaptability, and maturity, and can be strengthened over time.
1️⃣ Self-Directedness
This includes traits such as responsibility, purposefulness, competence, self-acceptance, and self-coherence.
Among its subscales, “Purposefulness” is particularly important in parenting and value formation.
💡 Ask yourself:
“When my life comes to an end, what would I like others to say about me?”
This reflection helps strengthen your sense of purpose.
2️⃣ Cooperativeness
This dimension includes understanding, empathy, generosity, altruism, and fairness toward others.
-
Below 30: May appear narrow-minded or lacking in understanding
-
Above 70: Warm, accepting, and harmonious in relationships
Cooperativeness grows from past experiences of empathy and acceptance.
To nurture it, especially in family life, it’s important for partners to show kindness and generosity toward each other and themselves.
3️⃣ Self-Transcendence
This area deals with values, philosophy, and existential meaning, describing one’s sense of connection to something greater than oneself.
-
Below 30: Sensitive to comparisons and others’ judgments
-
Above 70: Guided by personal happiness and inner values, less swayed by others’ opinions
However, large differences in this trait between partners can cause value conflicts, so understanding and adjusting to each other’s worldview is essential.
Subscales:
-
Creative Self-Forgetfulness – Ability to lose self-consciousness and fully engage
-
Transpersonal Identification – Feeling of unity with the universe and all living things
-
Spiritual Acceptance – Openness to meaning, spirituality, and transcendence

🌷 Reflections
Through this lecture, I gained a deeper understanding of my own temperament—and discovered that my husband and I have completely opposite innate traits. It was fascinating to see what we had intuitively sensed now reflected in objective data.
The instructor’s detailed explanation of each TCI scale helped me anticipate how we might understand our baby’s future personality better. I was also intrigued by how TCI, like MBTI, classifies personalities into “types,” but in a more detailed way—108 categories instead of 16. This allows for a richer and more precise understanding of individuals.
Just as MBTI types like “INFJ” or “ESTP” convey personality patterns, TCI results also reveal recognizable tendencies once you know what each trait represents. Although it might take time to memorize all combinations, I plan to keep my notes for future reference—especially when understanding my child’s temperament later on.
The lecture concluded with tips on parenting and discipline strategies for each temperament type, which I’m sure will be valuable once our baby arrives.
Interestingly, I learned about this free lecture shortly after writing down my “wishes” list—reminding me of something i read, “Once you set a clear goal, your brain’s Reticular Activating System (RAS) will find a way.” I’m grateful for how timely this opportunity appeared and hope my RAS continues to work hard for me as I take one step at a time.
