Cognitive Function Domains Test (256 questions)

new! This test seeks to introduce domains to separate how people talk about the cognitive functions. I recommend it if you’re looking for something well-rounded. Six different scoring methods are used to score your answers.

Cognitive Function Test (Grant/Brownsword) (96 questions)
Available in العربية, Čeština, Deutsch, English, Español, فارسی, Suomi, Français, Magyar, Bahasa indonesia, Italiano, 日本語, 한국어, Polski, Português, русский, ภาษาไทย, Türkçe, Tiếng Việt, 中文.
This test assesses your “cognitive functions,” an amalgamation of sets of theories related to Myers and Briggs’ sixteen types and processes them through three different algorithms. This test includes a guesstimate for your four-letter type by individually measuring your answers against the eight letter archetypes created by Myers and Briggs.
Maybe the most important thing this test has done is help spread the word that the alternating function stack (IEIE/EIEI) ubiquitous in typology communities is likely the creation of W. Harold Grant, and that this is simply a function stack, not the definitive stack.
