Researchers tested whether the gender of hurricane name affects perceived risk & evacuation intentions. 142 participants were given a scenario and a weather map on which either Hurricane Christopher or Hurricane Christina was displayed and reported their evacuation intentions (intentions scale: 1 = definitely will evacuate immediately, 7 = definitely will stay home). A two-way ANOVA with the gender of the hurricane name and participants' sex yielded a significant main effect of the gender of the hurricane name such that Christopher elicited a greater intention to act than did Christina [Mchristopher = 2.343, SD = 1.212 vs. Mchristina = 2.939, SD = 1.538; F(1,138) = 6.543, P = 0.012, R2 = 0.044]. There was no main effect of participant sex. There was no interaction between the gender of the hurricane name and participants' sex.
