In this talk I’ll describe an experiment to assess the effect of beliefs about gender in selecting oneself or a designated person to carry out a volunteering task. Participants in a volunteering task are given the option of selecting oneself or nominating someone from their group described to them in terms of cartoons depicting women and men displaying different emotional states: happy, neutral or unhappy. We introduce a treatment consisting of gender priming, We find that women offer to volunteer more than men, and that while neither the emotional affect or the gender of the nominated person per se influence designation, men in the unprimed condition are more likely to choose the happy female face. Our results provide evidence of both stereotyping by men and self-stereotyping by women: men are happy to pick any woman for the volunteering, though they display a preference for the happy woman, whilst women are both more sensitive to the mood displayed and prefer to pick women who might be happy to do it the less sexist they are. When it comes to actually carrying out the volunteering task, we find that, conditional on volunteering, women are more likely to actually follow through than men.
