The study was aimed at characterizing the exact algebraic structure of the love schema in order to trace possible changes in the conceptualization of love throughout the adult life cycle, notably as regards the weight attributed to the three components of love: passion, intimacy, and commitment. The methodological framework was the Functional Theory of Cognition. Irrespective of the gender and age of the participants (from 18 to 93), the structure of the love schema was shown to obey an equal-weight-averaging rule; the love schema was conceived as a strictly compensatory schema. Irrespective of age and gender, passion was the most important factor (w = 0.51), followed by intimacy (0.29) and commitment (0.20). The relationship between overall love value and degree of passion (or intimacy or commitment) was not conceived as a linear one, but as an exponential one. The weight of passion was shown to decline over age, and the weight of commitment was shown to increase over age. This change was, however, very limited and observed in elderly participants only.
