In the psychological literature, a distinction is often made between two types of love. [1] Hatfield and Walster define: [1]
Passionate love is also called romantic love in some literature, [1] [2] [3] [4] [5] and is sometimes called being "in love" [2] or compared to infatuation [6] [1] [7] and limerence. [1] [8]
Companionate love is compared to strong liking or friendship love, [2] and is sometimes called attachment. [6] [9] Companionate love is sometimes considered the same as the attachment referred to by attachment theory [5] or different [2] depending on the author.
In the Passionate Love Scale (PLS) form, Elaine Hatfield & Susan Sprecher define the components of passionate love as: [1] [10]
- Cognitive
- Intrusive thinking; preoccupation with the thoughts of the partner.
- Idealization of the loved one and the relationship.
- Desire for knowledge: to know and be known by the partner.
- Emotional
- Attraction to the other; pleasant feelings for the other when things go well.
- Ambivalence or negative feelings (emptiness, anxiety, despair) when things go awry.
- Longing for reciprocity.
- Desire for "complete union," permanency.
- Physiological (sexual) arousal.
- Behavioral
- Actions aimed at determining the other's feelings.
- Serving and helping the other.
Passionate love is more intense in the early stage of a relationship and often fades over time. [6] Companionate love is felt less intensely and often follows after passionate love in a relationship. [4] [8] Both passionate and companionate love contribute to relationship satisfaction. [2]
Note that while Elaine Hatfield originally described passionate love as having a component of sexual attraction, [1] contemporary authors generally agree that sexual attraction and romantic attraction are separate things. [3] [9] [5] [11] People are motivated to initiate and maintain a pair-bond in a way that's different from the sex drive. [12] [3] [5] [11] [13]
Passionate love is said to last about 12 to 18 months [14] or 18 months to 3 years, [4] depending on the estimate. Companionate love is thought to decrease very slowly over the course of several decades. [6]
A popular hypothesis suggests that passionate love turns into companionate love over time in a relationship, [1] [2] but other accounts suggest that while companionate love takes longer to develop, it is important at the beginning of a relationship as well. [2] [5]
A number of theories exist about the causal conditions surrounding passionate and companionate love (i.e. who people feel a certain love towards and when), [2] but authors generally agree that these follow different mechanics, [2] [3] and evolutionary theories suggest they exist for different purposes. [3] [5]
According to Ellen Berscheid, companionate love "follows the pleasure-pain principle; we like those who reward us and dislike those who punish us." [2] Examples of factors include similarity, familiarity, expressions of self-esteem and validation one's self-worth, physical attraction and mutual self-disclosures. [2] Also, while passionate love is often said to come before companionate love, [4] [5] Berscheid suggests that companionate love can also be a component in the development of passionate love. [2]
Authors disagree on the role sexual desire plays in the development of romantic love. [2] [15] [11] [5]
Passionate love is often associated with sexual desire, [2] [1] for example Berscheid suggests that one possible account of passionate love is "a felicitous combination of companionate love and sexual desire." [2] However, Lisa Diamond has suggested that while sexual desire is often a causal component, passionate love can occur outside the context of sexual desire. [11] Diamond's argument rests on various reports and historical accounts, as well as an evolutionary argument that the brain systems underlying romantic love evolved independent of sexual orientation. [11]
Helen Fisher has argued that passionate love is related to the phenomenon of mammalian courtship attraction, or mate choice, and that people have certain preferences for choosing a preferred mating partner that determine who they fall in love with. [15] However, Fisher argues this is distinct from the sex drive, although they are interrelated. [12] [3] [15]
Berscheid writes that emotional arousal, for example happy surprises, contributes to eliciting passionate feelings. [2] Surprise and uncertainty tend to be a characteristic of new relationships, so partners in established relationships tend to behave as one expects and thus rarely generate this sort of arousal. [2]
Elaine Hatfield has even suggested that negative or mixed emotions can amplify feelings of passionate love. [16] In A New Look at Love, she writes "Passion demands physical arousal and unpleasant experiences are just as arousing as pleasant ones." [16] Hatfield cites animal studies, such as one study in which puppies that were intermittently maltreated were the most attracted to and dependent on their trainer. People who behave consistently generate little emotion, she says, and "What would generate a spark of interest, however, is if our admiring friend suddenly started treating us with contempt—or if our arch enemy started inundating us with kindness." [16]
Another theory is that passion occurs when a rapid increase in intimacy occurs. [2] A similar theory, by Arthur Aron & Elaine Aron, states that passion occurs in the context of a rapid self-expansion of the self and the inclusion of the qualities of the beloved into one's self-concept. [2] With both of these theories, it's predicted that passion wanes in a relationship as partners get to know each other and the increase in intimacy tends to stabilize. [2]
Passionate and companionate love are thought to be interrelated, but involve different brain systems and serve different purposes. [3] [5] Passionate love is thought to have evolved for mate choice [15] or to initiate a pair bond, [5] while companionate love is for maintaining a pair bond, [5] maintaining close proximity and affiliative behaviors. [3]
Passionate love is primarily associated with the neurotransmitter dopamine. [3] [15] [5] Companionate love is primarily associated with the neuropeptide oxytocin, [3] [5] and sometimes vasopressin [3] and endogenous opioids. [5]
Passionate love is sometimes compared to an addiction, [1] [14] although there are differences. [17] People in the early stages of romantic love share similar traits with addicts (for example, feeling rushes of euphoria, or craving for their beloved), [14] but this tends to wear off over time, while the condition of a drug addiction tends to worsen. [17] Anthropologist Helen Fisher has suggested romantic love is a "positive addiction" (i.e. not harmful) when reciprocated and a "negative addiction" when unrequited or inappropriate. [14]
A 2012 study by Sandra Langeslag and others determined that while the PLS is commonly used to measure passionate love, some of the questions actually measure companionate love as well. [7] Langeslag developed a questionnaire to measure slightly different constructs, which she refers to as infatuation and attachment: [7] She describes them like this: [9]
Infatuation is the overwhelming, amorous feeling for one individual that is typically most intense during the early stage of love (i.e., when individuals are not (yet) in a relationship with their beloved or are in a new relationship). Attachment, on the other hand, is the comforting feeling of emotional bonding with another individual that takes some time to develop, often in the context of a romantic relationship.
Infatuation is analogous to passionate love, [6] and the questionnaire asks about: [7]
Attachment is analogous to companionate love, [6] and the questionnaire asks about: [7]
Infatuation and attachment co-occur, so one can feel them together at the same time, or feel infatuation strongly and attachment weakly and vice versa. [7] Langeslag found that infatuation is more associated with negative emotion than attachment, and tends to decrease after entering a relationship, while attachment tends to increase. [7] Participants who were not in a relationship scored the highest on infatuation. [7]
