Abstract

To determine whether or not love acts have changed since Buss first examined them in (1988) and to determine which love acts are perceived as most effective, three studies were implemented. Studies 1 and 2 presented questionnaires to college undergraduates. Study 3 used an internet based questionnaire and included college undergraduates and individuals from other environments. Study 1 (n =81) sought to ascertain the actions that men and women engage in to indicate love to a partner. Men and women’s love acts were expected to differ. Study 2 (n = 80) sought to ascertain which love acts are considered the most prototypical love acts. The most prominent love acts were expected to be rated as the most prototypical love acts. Study 3 (n = 137) sought to determine which actions are rated as the most effective love acts. The most prototypical love acts from Study 2 were expected to be rated as most effective by both sexes. The results were consistent with the hypotheses. These findings are discussed in terms of prior research.
