This study explored confusion between liking and loving. Rubin (1970) showed that males do not distinguish liking and loving toward their partner in a romantic relationship, while females do. The adaptationist perspective, however, predicts the opposite pattern for males and females who are not yet involved in a romantic relationship. To test the prediction, in this experiment, mutually unknown opposite sex dyads jointly engaged in a problem solving task and then assessed their partner with Rubin's love/like scale. The results indicated that the correlation between liking and loving was higher among females than males. Therefore, the adaptationist prediction was supported. Implications of the present study and possible future research topics are discussed.
