À propos de types psychologiques:

Intuition and sensation are the pair that perceive information, so they are called the "non-rational" functions, because they simply gather information in a non-critical way, that is, without processing it. Intuition and sensation perceive reality quite differently. Intuition is the perceiving function that sees things whole, or in the broad context. It grasps the big picture and also sees the implications. When it looks at something, it imagines where it came from and how it arrived at this palce. It looks for antecedents, for history, for broad general trends. It also speculates about the future, asking where is this going?. And perhaps, what is most important, intuition asks, what are the possibilities of what I'm seeing?
Sensation is the perceiving function that notices details. It is interested in the precise nature of things. It asks, what does it look like? How is it constructed? How does it function? Sensation likes to take apart things, data, ideas, to see what makes them tick. It will pursue its search for information until it finds every piece and fits it into a picture. Only then, when it is all complete, is it able to see the whole picture, but it has shown infinite patience in the process of gathering. Sensation depends very much upon the senses, which are its primary source of information. This is why it is called "sensation"

Thinking and feeling are the functions that process information. To do so, certain judgements must be made, therefore these two are called the "judging functions". However they process information in different ways. Having received information through either intuition or sensation, and most likely from both in varying degrees, it is now teh role of thinking or feeling to determine a course of action. Thinking proceeds with some deliberation, evaluating the situation and looking at the pros and cons. it applies certain values or standards to determine the general direction in which to move, and sets forth goals or objectives. Thinking then begins to formulate plans that will lead step by step from the data to the desired result. I am not speaking of business here, necessarily; although it may sound as if I am, but the thinking process can apply to any situation, to anyone, at any age. It is a reasoning process and it aims to carry through from beginning to end.
Feeling is also a judging process, but it operates quite differently from thinking to achieve its ends. Feeling depends upon a personal or subjective value system -there is something conscious or unconscious, against which objective reality is measured. Feeling operates with spontaneity , responding directly to a situation before analyzing its very aspects to determine its worth or usefulness. Feeling says: I like that, or that will never do. Feeling has a way of sizing up a person or a place without stopping to figure out why it comes to the conclusions it does. It can easily decide whether something is acceptable or not. Feeling is associated with empathy; the person with a strong feeling function can look into the face of another and realize that what the other is experiencing -pain or pelasure, hurt or anger. This is different from intuition, which sees things whole and does not have strong subjective responses. People with strong feeling functions base their responses to situations on their sense of what is right or wrong, appropiate or inappropiate, urgent or not urgent, or any other criteria by which something may be judged.
