Model A & Functions

Model A is a base of Socionics and explains it in most square (pun intended:) way. Ladies and Gentlemen, meet Model A:



Here is how it looks. It consists of 8 functions (cells)  where 8 aspects (black and white geometrical shapes) are located. Functions create a matrix, a skeleton of Model A. The set of aspects is the same for everyone, but different aspects can be located in different cells. Location of aspects in Model A will identify the socio-type of a person. Here you go, step 1 for us – to identify the socio-type of person in the beginning of communication and now we have a tool.


What are aspects? Aspects describe type of information (emotional, logical, sensorial, etc) we may receive from outside.

What are functions? Functions describe volumes of the information we can handle and the way we deal with it. For convenience further on we will describe volumes by 1D, 2D, 3D or 4D highest. So if we say that the function is 4D that means that person can handle as large amount of information as possibly exists, create solutions for unusual situations and apply them easily.

See how do we deal with information by each function:


Here I numbered functions from 1 to 8 for your convenience.

1 – Base Function. This is our strongest (4D) and the most pronounced function. This is what we think the world consists of and what the world actually is. Lets say we all wear sun glasses with different shades. This function identifies the color of the shade, the ultimate filter through which each of us looks at the world around him.

2 – Productive Function. This is how we actually act, solve tasks and manipulate. Its a bit weaker (3D) but it “sticks out” more than the Base one. This is what people notice first about us. If they need to describe our personality in one word, most probably this will be the word.

3 – Role Function. 2D, weak function which we use as a mask when they try to make a positive impression on someone. How often we hear “When I first met you I thought you were so and so but then I got to know you better – you are a totally different person!” – here you go. For some reason we think that this mask is our best self. However since the function is quite weak we cannot pretend for long (normally not more than 15 mins). In general this function for us is a marker of success in society – whoever masters it is perceived as a successful person.

4 – Point of Least Resistance (PoLR). As the name suggests it is our weakest function (1D) and the aspect in it is our most vulnerable area, the “painful spot”. We are unable to perceive information by this aspect in any other way but from our own experience. Any compliment, critisism or even a simple inquiry from others on that subject will trigger a reaction similar to a fish thrown out on the shore: person doesnt say anything, he can open and close his mouth without making a sound and generally looks very discouraged. As much as it looks funny it feels like someone knocked the wind out you. Read more about PoLR

5 – Suggestive Function. 1D, very weak function but unlike PoLR is not painful and we agree that we aren’t experts in that field. We don’t hesitate to ask for help on this aspect and we aren’t ashamed ( we are even happy ) to accept guidance or advice in that area. This function is best described as a bucket with no bottom. Information is gladly accepted and we crave more and more input on that aspect, we love discussing it but information there doesn’t accumulate, like bottomless bucket can never be filled up.

6 – Mobilizing Function. Slightly stronger – 2D, but still a function where we prefer to rely on expertise of others who are more savvy in this area. It is difficult to form own opinion in this field and often we attribute  to ourselves someone else’s opinion which seems to be valid (as much as we can evaluate this validity). This function is our soft spot, as many compliments and flattery as we could possibly receive will all be accepted and will only boost our self-esteem. Negativity and criticism by this aspect is taken personally and makes us depressed.

7 – Restrictive Function. Strong 3D function which is our great asset but ironically is least used. This area of knowledge is considered to be not interesting, not important and we can’t really tolerate too much talking about it. We restrict it. We can quite literally say: “Enough of that”, “Oh stop talking”, “Why do you even need to mention that?” We tend to leave it till the moment when its absolutely necessary to use this function. However when in use, its strong and we are able to use it to find solutions in unordinary situations.

8 – Background Function. Second strongest function we have (4D), which we use in the background, subconsciously, without paying attention and without talking about it. By this function we monitor whats going on and in case of disturbance of our peace (or our loved ones) we act immediately and without saying anything. If one tries to talk to us about it the reaction we will reject that. Subject is considered to be not interesting and not worth discussing.
