100 Definitions of Cognitive Functions & MBTI

Core Cognitive Functions (8 × 2 = 16)

Introverted Intuition (Ni)

• Short: Focuses on inner symbolic patterns and future insights.
• Extended: A perceiving process that seeks underlying meaning, condensing scattered impressions into singular visions, predictions, or revelations.

Extraverted Intuition (Ne)

• Short: Generates multiple external possibilities and connections.
• Extended: A perceiving process that rapidly explores ideas, associations, and potential outcomes in the outer world, often playful and imaginative.

Introverted Sensing (Si)

• Short: Recalls and references past experiences for stability.
• Extended: A perceiving process tied to memory, tradition, and consistency, comparing the present to established internal references and impressions.

Extraverted Sensing (Se)

• Short: Immerses in direct sensory experience and immediacy.
• Extended: A perceiving process tuned to real-time data, aesthetics, physical action, and the vivid reality of the present moment.

Introverted Thinking (Ti)

• Short: Builds inner logical frameworks and definitions.
• Extended: A judging process that dissects ideas, tests internal consistency, and forms precise categories, often prioritizing accuracy over efficiency.

Extraverted Thinking (Te)

• Short: Organizes the outer world with structure and efficiency.
• Extended: A judging process that measures, systematizes, and executes based on objective metrics, prioritizing results, clarity, and productivity.

Introverted Feeling (Fi)

• Short: Holds personal values and inner authenticity.
• Extended: A judging process that evaluates based on an internal moral compass, focusing on individual integrity, depth of feeling, and subjective worth.

Extraverted Feeling (Fe)

• Short: Reads and responds to others’ emotions and social harmony.
• Extended: A judging process that organizes relationships, builds group cohesion, and maintains external emotional dynamics.

MBTI Core Dimensions (8)

1. Introversion (I): Orientation toward the inner world of ideas, reflection, and energy conservation.
2. Extraversion (E): Orientation toward the outer world of action, interaction, and energy exchange.
3. Sensing (S): Preference for concrete, practical, sensory-based information.
4. Intuition (N): Preference for abstract, pattern-based, and symbolic information.
5. Thinking (T): Decision-making guided by logic and objective analysis.
6. Feeling (F): Decision-making guided by values and interpersonal considerations.
7. Judging (J): Preference for closure, order, and structured environments.
8. Perceiving (P): Preference for openness, flexibility, and adaptive environments.

• ESTP: Bold adventurer, thrives on action and real-time risks.

Key MBTI & Function Concepts (30)

1. Cognitive Stack: Order of 4 functions shaping a type’s perception and judgment.
2. Dominant Function: The strongest, most natural function in a type.
3. Auxiliary Function: Balances the dominant, second in strength.
4. Tertiary Function: Emerging support, often playful or underdeveloped.
5. Inferior Function: Weakest, often unconscious, and stress-prone.
6. Shadow Functions: Opposite-attitude functions, often unconscious or distorted.
7. Grip Stress: When the inferior function takes over under stress.
8. Loops: Over-reliance on dominant + tertiary, skipping auxiliary balance.
9. Cognitive Axis: Pair of introverted/extraverted versions of the same process (e.g., Ni–Se).
10. Attitudes: The introverted or extroverted direction of a function.
11. Perceiving Functions: Ni, Ne, Si, Se — gather information.
12. Judging Functions: Ti, Te, Fi, Fe — make decisions.
13. Temperaments: Four clusters (SJ, SP, NF, NT) with shared qualities.
14. Interaction Styles: Groupings by communication and energy patterns.
15. Function Hero: Jungian archetype of the dominant function.
16. Function Parent: Archetype of auxiliary, guides balance.
17. Function Child: Archetype of tertiary, playful, and vulnerable.
18. Function Inferior: Archetype of the weakest function, source of stress.
19. Anima/Animus: Archetype linked with inferior/shadow expression.
20. Complexes: Emotional knots tied to functions (Jung’s theory).
21. Persona: Outer mask; how functions present socially.
22. Shadow Archetypes: Trickster, demon, critic, witch, roles of shadow functions.
23. Function Loops Example: Ni–Ti loop in INFJs or Ne–Fi loop in ENFPs.
24. Opposing Role: First shadow function, often reactive.
25. Critical Parent Role: Second shadow function, often judgmental.
26. Trickster Role: Third shadow function, mischievous distortion.
27. Demon Role: Fourth shadow function, destructive potential.
28. Developmental Stages: Early life → dominant; adulthood → auxiliary/tertiary.
29. Balance: Healthy use of all four functions in the stack.
30. Type Dynamics: How functions interplay uniquely in each type.

Advanced & Related Terms (30)

1. Individuation: Jung’s process of integrating all functions into wholeness.
2. Projection: Attributing one’s own function content onto others.
3. Archetypes: Universal symbols embedded in functions.
4. Complex: Cluster of emotions/thoughts tied to functions.
5. Transcendent Function: Integrative process uniting opposites.
6. Synchronicity: Meaningful coincidences are often perceived via Ni.
7. Typology: Systematic classification of types.
8. Type Development: Lifelong unfolding of functional balance.
9. Preference vs. Skill: MBTI shows preference, not always ability.
10. Mistyping: Confusing one type for another due to surface traits.
11. Function Attitudes: Each function exists in both introverted and extraverted form.
12. Psychological Energy: Direction of attention shaping function use.
13. Cognitive Distortion: A Dysfunctional form of a function.
14. Flow State: Optimal integration of functions in action.
15. Persona–Shadow Tension: Conflict between outer mask and hidden functions.
16. Hero’s Journey (Type Lens): Growth of the dominant toward integration.
17. Type Polarities: Each type balances opposite function-attitudes.
18. Mirror Types: Same functions in opposite order (e.g., INFJ vs. ENFP).
19. Compatible Types: Shared axis or function resonance.
20. Conflicting Types: Different priorities, blind spots clash.
21. Enneagram vs. MBTI: Complementary but distinct systems.
22. Socionics: An Alternate model of types/functions from Russia.
23. Cognitive Style: Characteristic way a function processes data.
