I find these descriptions to be pretty damn good. unfortunately for whatever reason, there was nothing written for the 7th and 8th function, and the 6th function description seems a little short compared to the rest.
Model A functions:
1st. Base or Leading
4th. Vulnerable or Place/Point of Least Resistance (PoLR)
5th. Suggestive or Dual-seeking (DS)
6th. Mobilizing or "Hidden Agenda" (HA)
7th. Ignoring or Limiting
from www.socionika.com: Description of functions (information compiled from Sedykh’s “Funktsionika”, Leningrad, 1990)
The first function is the strongest and most conscious function and forms the core of one’s perception of reality. It perceives information with the greatest clarity and level of subtlety. Information is perceived and processed so rapidly that one doesn’t notice that one already has information available for use. One has near photographic memory of everything consciously registered or processed using one’s first function. The first function is constantly observing and studying reality and views this information element as an objective component of reality that everyone has a right to. The individual knows what channels exist to obtain authoritative information related to his first function and how to get this kind of information out to other people. One tries to become a specialist in areas relating to one’s first function and find the best standards to promote. The first function always has its distinct sphere of interests. Individuals are not shy about demonstrating their first function or receiving criticism about what they do or think using their first function. They also think little of criticizing others from the standpoint of their first function. One’s first function is what one tends to value most in oneself and what one identifies oneself most with. In one’s opinions and activities related to one’s first function one rarely yields to others’ influence and is capable of standing up for oneself and leading others. The first function is interested in others just as much or more than oneself and needs a large field to apply itself. It needs people that will heed its qualified advice and accept its program.
The second function is the psyche’s second most conscious function after the first. The individual uses it a tool to achieve one’s goals related to one’s first function and perceives this aspect of reality as a means, not an end. By honing this tool to serve the first function’s demands, one discovers or invents something new or hitherto unknown. Hence the name “creative function.” One prefers to create one’s new version of things relating to one’s second function rather than dig through old material that one doesn’t try hard to remember, anyway. Individuals view their second function more as their own personal skill or quality than as an objective component of reality. Hence, criticism is more unpleasant than for the first function. At the same time, when others need our help using our second function, this is seen as acknowledging our success in this area, and we help out with pleasure and enthusiasm. One believes that everyone should have the right to freedom and creativity in this aspect of reality. If no one needs our help in this aspect of reality we feel unneeded. The more those around us need our expertise in this area, the greater our self-actualization in society.
The third function receives less attention than the first two and accumulates information sporadically. One is never completely sure of whether one perceives things accurately with it or not, and one’s memory of things is often quite foggy. There is not always enough information available about this aspect of reality even for the individual himself to get by. The third function does not have its own distinct sphere of interests; almost any information out of the norm can interest the individual. When making decisions about this aspect of reality the individual hesitates and is unsure of himself and tries to get advice from others if he is sure they will treat him respectfully. The third function is quite sensitive to criticism and tries not to criticize or impose on others. Since it is difficult to withstand or counter other peoples’ views about this aspect of reality, individuals try to meet accepted standards and be at least average in this area. If they do make mistakes, they usually feel bad that others have not taught them to do better. In this area a person can give advice based on what they have heard from others but is usually too unsure of himself to actually help out. The third function needs others to help out without making a big deal of it. One needs to have someone who is always there to discuss issues relating to this function and approve one’s decisions. In this case the individual becomes much more self-assured and secure and begins to live more fully. And gradually his third function becomes an encyclopedia of useful information that others can gain much use from. The calmer and more secure one is about everything relating to one’s third function and the more attention one gives it, the greater one’s success. But the third function is never as categorical and forceful as the first and can never rise to the same heights of vision. At its best development it remains a practical instrument to serve the interests of the individual and those immediately surrounding him.
The fourth function is the weakest of the mental functions. It perceives information superficially at best. The third function provides it with little information for making confident judgments and decisions. It is very difficult to withstand pressure from others. Pressure or excessive information related to this aspect of reality is seen as tactless and can cause a multitude of complexes, neuroses, and unhealthy reactions to one’s surroundings (self-flagellation to arouse pity, imagining things that don’t actually exist, etc.). The individual tries not to interfere in other’s business (unless it directly affects him) and doesn’t like people who are curious or pushy in this aspect of reality. Discussion of these things is possible only if one raises the subject oneself. Any excessive attention given to these things sets one on guard – even compliments (unless one is absolutely sure of the other’s sincerity). One tends to blow failures and criticism (real or perceived) of one’s fourth function out of proportion and mull over them for days, causing a sort of mental paralysis and lengthy self-reevaluation. The fourth function has difficulty understanding and remembering information and tends to resort to generalizations that are often primitive and lopsided. One’s fourth function is especially sensitive to criticism and requires tactful concern from others, not criticism. What one’s fourth function really needs is freedom of manifestation without outside commentary and a friend whose opinion in this aspect of reality can always be counted on. Otherwise steady “attacks” on this function can turn life into a prison where one feels like one is constantly being watched and judged.
The fifth function has great difficulty making sense of information on its own. Information is perceived on the one hand as little understood background noise and on the other hand as something of great importance. The individual feels good when others explain to him what he is experiencing in this aspect of reality and what he should do about it. One’s opinions in this area are easily influenced. Without others’ care and concern one feels like an abandoned child. A person rarely feels ashamed about problems related to his fifth function and can easily request help if he sees that others are self-assured in this area. If others speak with an authoritative tone, one listens carefully to advice having to do with one’s fifth function. One rarely stands up for the fifth function’s interests, but accepts as much help as others are willing to give. Criticism is interpreted as concern for one’s needs. People who lack duals’ concern in this area frequently hint at their fifth function’s helplessness and neediness in the subconscious hope that the right people will respond to their cry for help. Dualization helps to develop the fifth function and make sense of one’s subconscious needs in this area. Self-perfection on one’s own is extremely difficult. If the individual has someone he trusts to follow, he feels happy and protected. Otherwise he feels resentful of society at large for not providing him with the care and assistance he needs.
The sixth function is where one’s instinctive reactions to signals coming from the fifth function form. This is the area where a person has the least conscious freedom. One is very poorly aware of the state of one’s sixth function. Criticism is unpleasant and arouses responses like “either help me or keep your mouth shut.” An individual tries to liquidate any negative influences that make it harder for the sixth function to operate. On the other hand, praise of one’s sixth function is the best compliment possible. Any help and concern in this area a person is openly grateful for and tries to reciprocate. Any malfunctions or maladjustments of the sixth function seriously impair the psyche’s operation.
