Culture Sometimes Matters: Intra-Cultural Variation In Pro-Social Behavior Among Tsimane Amerindians, Michael Gurven, Arianna Zanolini, Eric Schniter

Agent-centered models usually consider only individual-level variables in calculations of economic costs and benefits. There has been little consideration of social or cultural history on shaping payoffs in ways that impact decisions. To examine the role of local expectations on economic behavior, we explore whether village affiliation accounts for the variation in dictator game offers among the Tsimane of the Bolivian Amazon independently of other factors that could confound such an effect. Our analysis shows that significant differences in altruistic giving exist among villages, village patterns are recognized by residents, and offers likely reflect variation in social expectations rather than …


"My Loss Is Your Gain": Examining The Role Of Message Frame, Perceived Risk, And Ambivalence In The Decision To Become An Organ Donor., Elizabeth Leigh Cohen Aug 2007

"My Loss Is Your Gain": Examining The Role Of Message Frame, Perceived Risk, And Ambivalence In The Decision To Become An Organ Donor., Elizabeth Leigh Cohen

Communication Theses

The decision to become an organ donor involves considering both self-relevant risks and the needs of others. This study applied prospect theory to examine how message frames that focus on the possible survival or death of a potential organ transplant recipient affect participants' willingness to become organ donors. Perceived personal risk and ambivalence were examined as moderating variables. Results indicate that risk, rather than ambivalence, played an instrumental role in participants' decisions to donate. Although no main effects or interactions related to message frame emerged in initial analyses, a supplemental analysis revealed a modest persuasive advantage for the loss-framed message …


Attitude-Dependent Altruism, Turnout And Voting, Julio J. Rotemberg Jan 2007

Attitude-Dependent Altruism, Turnout And Voting, Julio J. Rotemberg

Julio J Rotemberg

This paper presents a goal-oriented model of political participation based on two psychological assumptions. The first is that people are more altruistic towards individuals that agree with them and the second is that people's well-being rises when other people share their personal opinions. By conveying credible information on attitudes, voters give pleasure to individuals who agree with them and thereby confer vicarious utility on the voters themselves. Substantial equilibrium turnout emerges with nontrivial voting costs and modest altruism. The model can explain higher turnout in close elections as well as higher turnout by more informed and more educated individuals. It …


Oxytocin Increases Generosity In Humans, Paul J. Zak, Angela Stanton, Sheila Ahmadi Jan 2007

Oxytocin Increases Generosity In Humans, Paul J. Zak, Angela Stanton, Sheila Ahmadi

Business Faculty Articles and Research

Human beings routinely help strangers at costs to themselves. Sometimes the help offered is generous-offering more than the other expects. The proximate mechanisms supporting generosity are not well-understood, but several lines of research suggest a role for empathy. In this study, participants were infused with 40 IU oxytocin (OT) or placebo and engaged in a blinded, one-shot decision on how to split a sum of money with a stranger that could be rejected. Those on OT were 80% more generous than those given a placebo. OT had no effect on a unilateral monetary transfer task dissociating generosity from altruism. OT …

The Impact Of College Student Immersion Service Learning Trips On Coping With Stress And Vocational Identity, Brad A. Mills, Richard B. Bersamina, Thomas G. Plante Jan 2007

The Impact Of College Student Immersion Service Learning Trips On Coping With Stress And Vocational Identity, Brad A. Mills, Richard B. Bersamina, Thomas G. Plante

Psychology

This study examined the impact of service learning immersion trips on vocational identity and coping with stress among college students. Fifty-one students (15 males, 36 females) who participated in immersion trips and 76 students (25 males, 51 females) in a non-immersion control group completed a series of questionnaires directly before and immediately after both fall and spring break immersion trips, and during a four-month follow up. Results suggest that, after returning from an immersion trip, students report a greater ability to cope with stress and a somewhat stronger sense of vocational identity relative to students who do not participate in …
