Falling in love

"Factors known to contribute strongly to falling in love include proximity, similarity, reciprocity, and physical attractiveness",[3] while at the same time, the process involves a re-activation of old childhood patterns of attachment.[4] Deep-set psychological parallels between two people may also underpin their pairing-bonding,[5] which can thus border on mere narcissistic identification".[6]

Jungians view the process of falling in love as one of projecting the anima or animus onto the other person, with all the potential for misunderstanding that can involve.[7]

Jean-Honoré Fragonard—The Stolen Kiss (circa late 1780s).

Two chemical reactions associated with falling in love are increases in oxytocin and vasopressin;[8] and Elisabeth Young-Bruehl has suggested that "when we fall in love we are falling into a stream of naturally occurring amphetamines running through the emotional centres of our very own brains".[6] With regard to sociobiology, it is stressed that mate selection cannot be left to the head alone[9] and must require complex neurochemical support.[10]

Critics of such Neo-Darwinism point out that over-simplistic physical arguments obscure the way sexual passion often leads not to secure attachment but to attachments thwarted, as well as the sheer frightening difficulties of all falling in love.[11]

Biologist Jeremy Griffith suggests that people fall in love in order to abandon themselves to the dream of an ideal state (being one free of the human condition).

"Sexual desire and love not only show differences but also recruit a striking common set of brain areas that mediate somatosensory integration, reward expectation, and social cognition"[12] Neuroimaging studies show that love and sexual desire share common chemical reactions in the brain. Both love and lust show neural activation in regions such as the cortical area (eg., middle gyrus, superior temporal guys, temporo-parietal junction, and occipital-temporal cortices) and the subcortical brain areas (eg., striatum, thalamus, hippocampus, anterior cingulate cortex, and ventral segmental area).[13] The cortical area of the brain is correlated with a persons self-representation, goals-directed actions, and body image while the sub.[13] Neuroimaging can also show the difference between love and desire.[13] Some brain regions that contribute to either love or lust are the anterior inusla, posterior insula, and the ventral striatum.[13] The anterior insula activates factors that contribute to love such as integrative representations. Where as the posterior insula are involved with factors that contribute to desire such as current sensations, feelings, and responses.[13] The ventral striatum however, becomes activated during pleasurable rewarding experiences such as sex or food.[13]

Many studies have show a positive linear correlation between romantic popularity and physical attractiveness for woman more than men.[14] Studies have shown that men subconsciously seek slenderness and sexiness whereas women seek status, permanence, and affluence before they seek physical attractiveness.[14]
