Intention and Performance
Intention is a person's aspiration to his or her goals. Neisser (1976) argues that cognition as knowing and understanding occurs only in the context of purposeful activity. We normally have a strong will to self-actualize what we want to become. Thus, intentions become the purposeful activities that our visions create. Intentions are normally driven in part by engagement.
Intention seems to characterize mind; while natural objects, such as atoms, chairs, or planets, do not have intentions, rather they are controlled by the natural laws. The forming of an intention seems to imply a free will and the ability to choose.
