Interpersonal chemistry

Interpersonal attraction is the attraction between people which leads to friendships and to platonic or romantic relationships. Interpersonal attraction, the process, is distinct from perceptions of physical attractiveness, which involves views of what is and is not considered beautiful or attractive.

The study of interpersonal attraction is a major area of research in social psychology. Interpersonal attraction is related to how much one likes, dislikes or hates someone. It can be viewed as a force acting between two people that tends to draw them together and resist their separation. When measuring interpersonal attraction, one must refer to the qualities of the attracted as well as the qualities of the attractor to achieve predictive accuracy. It is suggested that to determine attraction, both the personalities and the situation must be taken into account. Repulsion is also a factor in the process of interpersonal attraction; one's conception of "attraction" to another can vary from extreme attraction to extreme repulsion.

Interpersonal attraction is most frequently measured using the 'Interpersonal Attraction Judgment Scale' developed by Donn Byrne. It is a scale in which a subject "rates" another person on dimensions such as intelligence, knowledge of current events, morality, adjustment, likability and desirability as a work partner. This scale seems to be directly related with other measures of social attraction such as social choice, feelings of desire for a date, sexual partner or spouse, voluntary physical proximity, frequency of eye contact, etc.

Kiesler and Goldberg analyzed a variety of response measures that were typically utilized as measures of attraction and extracted two factors: The first, characterized as primarily socioemotional, included variables such as liking, desirability of the person's inclusion in social clubs and parties, seating choices, and lunching together. The second factor included variables such as voting for, admiration and respect for, and also seeking the opinion of the target. Another widely used measurement technique scales verbal responses expressed as subjective ratings or judgments of the person of interest.

Many factors leading to interpersonal attraction have been studied, all of which involve social reinforcement. The most frequently studied are physical attractiveness, propinquity, familiarity, similarity, complementarity, reciprocal liking, and reinforcement.
