Understanding Cognitive Functions
A guide to type-dynamics terminology, not a personal assessment
What are Cognitive Functions?
In Myers-Briggs type dynamics, cognitive functions are theoretical terms for perception and judgment. This page explains that vocabulary; it does not identify anyone’s functions from behavior.
Terminology source: Type Dynamics Overview — Mental ProcessesPerceiving (N/S)
The framework groups Sensing (S) and Intuition (N) as perceiving processes: terminology about taking in information.
Judging (T/F)
The framework groups Thinking (T) and Feeling (F) as judging processes: terminology about making decisions.
Introverted
In this terminology, introverted refers to an inward orientation.
Extraverted
In this terminology, extraverted refers to an outward orientation.
The 8 Functions
A theoretical lens on preferences; these functions are not directly measured by this questionnaire.
Introverted Intuition
In Myers-Briggs type-dynamics terminology, Ni connects internal images, themes, and associations to see something in a new way.

Extraverted Intuition
In Myers-Briggs type-dynamics terminology, Ne sees possibilities in the external world and forms patterns and connections among them.

Introverted Sensing
In Myers-Briggs type-dynamics terminology, Si compares present facts and situations with past experience.

Extraverted Sensing
In Myers-Briggs type-dynamics terminology, Se acts on concrete information in the here and now.

Introverted Thinking
In Myers-Briggs type-dynamics terminology, Ti seeks internal consistency and logic among ideas.

Extraverted Thinking
In Myers-Briggs type-dynamics terminology, Te seeks logic and consistency in external laws and rules.

Introverted Feeling
In Myers-Briggs type-dynamics terminology, Fi seeks harmony between actions, thoughts, and personal values.

Extraverted Feeling
In Myers-Briggs type-dynamics terminology, Fe seeks harmony with and between people, with attention to interpersonal and cultural values.

Sources and editorial scope
Questionnaire results
Scores summarize questionnaire answers. Percentages are scale positions, not accuracy or the probability of being a type. A type profile without scores is not a personal assessment.
OEJTS 1.2 questionnaire (PDF) Pages 1–3: license, 32 items and scoring rules for the source questionnaire. This is not a validation study of OpenJung, its quick test or translations.
OEJTS development “Item generation and evaluation” describes selection using self-identified types; “Versions and other downloads” links to version 1.2. This is development history, not validation of this adaptation.
Type theory
Type descriptions and cognitive-function order are interpretive frameworks. This questionnaire does not directly measure functions, abilities, maturity or relationship compatibility.
Myers & Briggs Foundation: type dynamics “Terminology of Type Dynamics” and “Order of the Mental Processes” explain terms in that framework. They do not verify this site’s individual trait claims or establish personal stress mechanisms.
Myers & Briggs Foundation: the processes of type dynamics “The Eight Dominant Processes” supports the eight card definitions as theory terminology only. “Tertiary Process (Third Process)” describes disagreement about its orientation. Neither validates OpenJung or the editorial examples and questions.
Optional practice
Career questions, stress prompts and small actions are editorial suggestions to try in a real situation. They are not measured findings about you, treatments or promises of improvement. Cat scenes are fictional illustrations.
Record updated:
The recorded edits and source checks were AI-assisted (Amp). No independent expert review is recorded; this date is not a certification date.
What was checked
The learning page now uses 16 explicitly fictional scenarios with alternative explanations and a 12-question terminology/boundary bank. Each eight-question round reports correct-answer counts only. Explanations distinguish source terminology from OpenJung editorial boundaries. Overview, metadata and five-language UI use the same scope, with labelled English fallback elsewhere. This is an AI-assisted editorial revision, not expert review or validation.
The function-stack exercise now identifies matches and unlisted orders only within the site’s unchanged 16-entry mapping. Position names, opposite pairs and disputed tertiary orientation have scoped sources. Five-language instructions and keyboard interactions were checked; this is not a personal assessment or validation of the mapping.
What remains unreviewed
Type nicknames, temperament group names, and other untranslated content have not received a full source-by-source review. Lifestyle lists were removed rather than rewritten; Guess-the-Type scenes remain fictional mapping drills, not function identification. The independent mobile dataset has not been updated. These edits do not establish independent expert review or a validation study.
GitHub issues are public. The draft includes only the public page, type and language—not scores, answers or private result links. Add only the relevant excerpt and source.
