Functions of the A-model. The four dimensions of a function
Extract from the book of Eglit I.M. "Socionic type identification. From A to Z tutorial"

Parameters of information processing of model A are described.

Function, socionic, TIM model, mental track, vital track, dimensions of a function, the "experience" parameter, the parameter of experience, parameter of norms, parameter of time, parmeter of situations

Each function has a certain set of properties which distinguish it from the other functions. Knowing these properties, you can learn to recognize the "signature" of a function, showing through a person’s speech.
There are three characteristics that differentiate one function from another:
1. Dimension (one-, two-, three-or four-dimensional).
2. Sign ("plus" or "minus").
3. Track (vital or mental).
Combination of these three properties determine the location of a function in a specific TIM model and its distinctive features related to information processing.
