Attraction can be defined as the romantic desire for a specific person for mating and it develops out of lust and commitment to another individual.

BIOLOGICAL FACTORS
Effect of hormones and neurotransmission- The researchers found out that there are two hormones in our body that help to increase the bond between each other. The attachment of the adults may due to the release of hormones oxytocin and vasopressin. Oxytocin is a hormone that release in both men and women during touching and sex. This hormone tends to deepen and intensify feeling of attachment. Moreover, oxytocin also releases during childbirth and this help secure the bond between the mother and the infant. Another hormone that helps increase the bond is vasopressin. This hormone is important for long-term commitment and it is releases during sex. Adrenalin is a stress hormone and when the adrenalin level increase, it will result in high energy, less need for sleep and food and focused attention on the potential mate. Serotonin is another neurotransmitter that may involved in love.
