This study tested the effect of semantically-induced thoughts of love on chivalrous helping. A field setting of four hundred and one participants was divided into two groups. One group was interviewed and asked to retrieve the memory of a love episode, and the second group, the control group, was asked to retrieve a piece of music that they love. The two groups encountered another confederate, who inadvertently lost a stack of compact discs when they neared each other. The results demonstrated that participants were more helpful when they were male, when the person in need of help was female, and when they were induced to retrieve the memory of a love episode.Keywords Love . Helping behavior . Sex roles Much of the work on helping behavior has been conducted in laboratory settings, and thus its generalizability to the real world remains unsure. In addition, studies of sex differences and helping behaviors have given contradictory and inconclusive results. Men have been found to help more than women (Guéguen and FischerLokou 2004). Women have been found to help more than men (Bihm et al. 1979). Other studies have shown little or no sex difference (Boice and Goldman 1981; Monk-Turner et al. 2002). Further, individuals of both sexes have been found to help experimenters of the other sex more often than members of their own sex (Basow and Crawley 1982). Men have been found to help women more than men (Rabinowitz et al. 1997), and men have been found to help women more than women do (Wilson and Kennedy 2006). Women have been found to help women more than men do (Bihm et al. 1979). Women have also been found to help both Curr Psychol (
