 Reciprocal liking and desirability of a person appear to be the most influential when falling in love.Aron et Al (1989) reported that in their sample of Canadian college students who recently fell in love, approximately 90% of them mentioned some indicator of thinking that the other person was attracted to them and the study also showed that maintaining eye contact was the most common clue.It has also been shown that people often flatter and praise people whose favour they are trying to win, and people said that they even modify their self-presentation to better fit the expectations or preferences of the person to whom they are attracted, or from whom they are seeking attention or affection.
