Scientific Models of Love

Scientific models

Biological models of love tend to see it as a mammalian drive, just like hunger or thirst. Psychology sees love as more of a social and cultural phenomenon. There are probably elements of truth in both views — certainly love is influenced by hormones (such as oxytocin) and pheromones, and how people think and behave in love is influenced by their conceptions of love.

Attraction and attachment

The conventional view in biology is that there are two major drives in love — sexual attraction and attachment. Attachment between adults is presumed to work on the same principles that lead an infant to become attached to its mother.

Companionate vs. passionate

The traditional psychological view sees love as being a combination of companionate love and passionate love. Passionate love is intense longing, and is often accompanied by physiological arousal (shortness of breath, rapid heart rate). Companionate love is affection and a feeling of intimacy not accompanied by physiological arousal.

Sternberg's Triangular Theory of Love

In the triangular theory of love, love is characterized by three elements: intimacy, passion and commitment. Each of these elements can be present in a relationship, producing the following combinations:

Combinations of intimacy, passion, and commitment

Liking or friendship	intimacy
Infatuation or limerence		passion
Empty love			commitment
Romantic love	intimacy	passion
Companionate love	intimacy		commitment
Fatuous love		passion	commitment
Consummate love	intimacy	passion	commitment

1. Liking includes only one of the love components - intimacy. In this case, liking is not used in a trivial sense. Sternberg says that this intimate liking characterizes true friendships, in which a person feels a bondedness, a warmth, and a closeness with another but not intense passion or long-term commitment.
2. Infatuated love consists solely of passion and is often what is felt as "love at first sight." But without the intimacy and the commitment components of love, infatuated love may disappear suddenly.
3. Empty love consists of the commitment component without intimacy or passion. Sometimes, a stronger love deteriorates into empty love, in which the commitment remains, but the intimacy and passion have died. In cultures in which arranged marriages are common, relationships often begin as empty love.
4. Romantic love is a combination of intimacy and passion. Romantic lovers are bonded emotionally (as in liking) and physically through passionate arousal.
5. Companionate love consists of intimacy and commitment. This type of love is often found in marriages in which the passion has gone out of the relationship, but a deep affection and commitment remain.
6. Fatuous love has the passion and the commitment components but not the intimacy component. This type of love can be exemplified by a whirlwind courtship and marriage in which a commitment is motivated largely by passion, without the stabilizing influence of intimacy.
7. Consummate love is the only type of love that includes all three components--intimacy, passion and commitment. Consummate love is the most complete form of love, and it represents the ideal love relationship for which many people strive but which apparently few achieve. Sternberg cautions that maintaining a consummate love may be even harder than achieving it. He stresses the importance of translating the components of love into action. "Without expression," he warns, "even the greatest of loves can die" (1987, p.341).
