Sensing individuals are described as very aware of their immediate environment. They are the first to notice when the seasons change or when the birds migrate. Intuitives, on the other hand, are less concerned with the here and now and more aware of the potential of a given situation. People familiar with Jung's theory and their own type claim that sensing types, because of their awareness of the immediate environment, should be more aware of physical changes in their bodies than intuitive types are. Persons who are oriented to life primarily through sensing perception typically develop acute powers of observation, a memory for facts and detail, a capacity for realism and an enjoyment of the pleasures of the immediate moment. Persons who are oriented to life primarily through intuitive perception typically are attuned to future possibilities, often creative ones, and develop the ability to see patterns at theoretical or abstract levels and to enjoy the play of imagination. (McCaulley, 1981, p. 299) Judgment can be either thinking (T) or feeling (F). Thinking types tend to be analytical and logical. They prefer to react to a situation objectively relying on factual evidence.
