FIXATION:
In human psychology, fixation refers to a state in which an individual becomes obsessed with an attachment to another person, being or object.
Sigmund Freud theorized that humans may develop psychological fixation due to:
A lack of proper gratification during one of the psychosexual stages of development, or
Receiving too strong of an impression from one of these stages, in which case the person's personality would reflect that stage throughout adult life.
Whether a particularly obsessive attachment is a fixation or a defensible expression of love is at times debatable. Fixation to intangibles (i.e., ideas, ideologies, etc.) can also occur. The obsessive factor is also found in symptoms pertaining to obsessive compulsive disorder.
