Romantic love: a mammalian brain system for mate choice.

Abstract: Mammals and birds regularly express mate preferences and make mate choices. Data on mate choice among mammals suggest that this behavioural 'attraction system' is associated with dopaminergic reward pathways in the brain. It has been proposed that intense romantic love, a human cross-cultural universal, is a developed form of this attraction system. To begin to determine the neural mechanisms associated with romantic attraction in humans, we used functional magnetic resonance imaging (fMRI) to study 17 people who were intensely 'in love'. Activation specific to the beloved occurred in the brainstem right ventral tegmental area and right postero-dorsal body of the caudate nucleus. These and other results suggest that dopaminergic reward and motivation pathways contribute to aspects of romantic love. We also used fMRI to study 15 men and women who had just been rejected in love. Preliminary analysis showed activity specific to the beloved in related regions of the reward system associated with monetary gambling for uncertain large gains and losses, and in regions of the lateral orbitofrontal cortex associated with theory of mind, obsessive/compulsive behaviours and controlling anger. These data contribute to our view that romantic love is one of the three primary brain systems that evolved in avian and mammalian species to direct reproduction. The sex drive evolved to motivate individuals to seek a range of mating partners; attraction evolved to motivate individuals to prefer and pursue specific partners; and attachment evolved to motivate individuals to remain together long enough to complete species-specific parenting duties. These three behavioural repertoires appear to be based on brain systems that are largely distinct yet interrelated, and they interact in specific ways to orchestrate reproduction, using both hormones and monoamines. Romantic attraction in humans and its antecedent in other mammalian species play a primary role: this neural mechanism motivates individuals to focus their courtship energy on specific others, thereby conserving valuable time and metabolic energy, and facilitating mate choice.

Losing a self-expanding relationship: Implications for the self-concept.

Abstract: Previous research suggests that new relationships expand the self-concept. The present research applies concepts from the self-expansion model to examine the conditions under which relationship dissolution may influence the self-concept. We hypothesized that the more expansion provided by a relationship predissolution, the greater the contraction of the working self-concept postdissolution, and that this pattern would remain when controlling for predissolution closeness. These hypotheses were tested using recall of relationship qualities for recently dissolved relationships (Studies 1 and 2), as well as with a priming experiment (Study 3). The findings over the 3 studies supported both hypotheses. Those with higher levels of self-expansion in predissolution relationships showed more detrimental impact on their working self-concept postdissolution, even after controlling for predissolution closeness.

When similars do not attract: Tests of a prediction from the self-expansion model.

Abstract: This study tested the hypothesis from the self-expansion model that the usual effect of greater attraction to a similar (vs. dissimilar) stranger will be reduced or reversed when a person is given information that a relationship would be likely to develop (i.e., that they would be very likely to get along) with the other person. The study employed the ‘‘bogus stranger’’ paradigm and focused on similarity/dissimilarity of interests in the context of attraction to a samegender other. The effect for similarity under conditions in which no information is given about relationship likelihood replicated the usual pattern of greater attraction to similars. However, as predicted, a significant similarity by information interaction demonstrated that this effect was significantly reduced (and slightly reversed) when participants had been given information that the partner will like self. In analyses for each gender separately, both of these effects were significant only for men, suggesting that the focus on interest similarity may have been less relevant for women.
