The Effectiveness of Models and Prompts on Waste Diversion: A Field Experiment on Composting by Cafeteria Patrons

This study investigated whether or not visual prompts and human models influence compost‐supportive behavior by individuals in a cafeteria setting. Waste disposal behavior of cafeteria patrons was observed (N = 1,060) after the introduction of (1) pro‐composting signs, and (2) models who demonstrated appropriate composting behavior. Ideal composting significantly increased relative to the baseline with the introduction of the signs (from 12.5% to 20.5%). A further increase (to 42%) was observed when two (but not one) individuals modeled the behavior, and this increase was sustained even after the models were removed. Informational and normative influences may explain the increase in composting. This study further supports the use of prompts and models as a strategy for encouraging pro‐environmental behaviors.     

Skepticism and elegance: problems for the abductivist reply to Cartesian skepticism

Some philosophers argue that we are justified in rejecting skepticism because it is explanatorily inferior to more commonsense hypotheses about the world. Focusing on the work of Jonathan Vogel, I show that this “abductivist” or “inference to the best explanation” response rests on an impoverished explanatory framework which ignores the explanatory gap between an object's having certain properties and its appearing to have those properties. Once this gap is appreciated, I argue, the abductivist strategy is defeated.     

Psychology's contributions to understanding and addressing global climate change

Global climate change poses one of the greatest challenges facing humanity in this century. This article, which introduces the American Psychologist special issue on global climate change, follows from the report of the American Psychological Association Task Force on the Interface Between Psychology and Global Climate Change. In this article, we place psychological dimensions of climate change within the broader context of human dimensions of climate change by addressing (a) human causes of, consequences of, and responses (adaptation and mitigation) to climate change and (b) the links between these aspects of climate change and cognitive, affective, motivational, interpersonal, and organizational responses and processes. Characteristics of psychology that cross content domains and that make the field well suited for providing an understanding of climate change and addressing its challenges are highlighted. We also consider ethical imperatives for psychologists' involvement and provide suggestions for ways to increase psychologists' contribution to the science of climate change.     

Shifting preferences for choice‐making opportunities through histories of differential reinforcer quality

Children of both typical and atypical cognitive development tend to prefer contexts in which their behavior results in a choice of reinforcers rather than a single reinforcer, even when the reinforcer accessed is identical across conditions. The origin of this preference has been attributed speculatively to behavioral histories in which choice making tends to be associated with differentially beneficial outcomes. Few studies have evaluated this claim, and those that have, have yielded mixed results. We provided five preschool‐aged children experiences in which choice‐making and no‐choice contexts were differentially associated with higher preference and larger magnitude reinforcers, and we assessed changes in their preference for choice and no‐choice contexts in which outcomes were equated. These conditioning experiences resulted in consistent and replicable shifts in child preference, indicating that preference for choice is malleable through experience.     

Religion in Contemporary Senegal

Senegal is usually classified as 90% Muslim and 5% Christian. But Senegal’s dominant religious imagination is far different from anything suggested by classical labels like ‘Muslim’ or even ‘Sufi Brotherhoods’. The pervasive religious imagination sees spiritual forces at play everywhere and understands causality primarily in spiritual terms. These spiritual forces can be manipulated by individuals gifted with such powers (marabouts), positively for one’s advancement or negatively to counter or even bring down competitors or opponents. This enchanted religious imagination, often given an Islamic character, is obtrusive in Senegal’s major sports: lutte avec frappe and football. It is inescapable in politics, as politicians admit their recourse to marabouts and even more often accuse opponents of it. For women maraboutage is particularly employed for domestic realities: a husband, children, domestic security. The courts regularly feature cases arising from this imagination. The phenomenon merits research, not just to clarify the nature of Senegal’s religion itself, but also for its effects on the country’s socio-political development generally.     

Factors influencing car use for commuting and the intention to reduce it: A question of self-interest or morality?

Car use for commuting contributes to various environmental and traffic problems, such as pollution and congestion. Policies aimed at reducing commuter car use will be more effective when they target important determinants of car use and willingness to reduce it. This study examined whether variables reflecting self-interest (from the theory of planned behavior [Ajzen, I. (1985). From intentions to actions: A theory of planned behavior. In J. Kuhl & J. Beckmann (Eds.), Action control: From cognition to behavior (pp. 11–39). Berlin: Springer]) and variables reflecting moral considerations (from the norm-activation model [Schwartz, S. H. (1977). Normative influences on altruism. In L. Berkowitz (Ed.). Advances in experimental social psychology (Vol. 10, pp. 221–279). New York: Academic Press]) were able to explain self-reported car use for commuting and intentions to reduce it in a sample of Canadian office workers. Car use for commuting was mostly explained by variables related to individual outcomes (perceived behavioral control and attitudes) whereas the intention to reduce car use was mostly explained by variables related to morality (personal norms). The study also found that perceived behavioral control moderated the relation between personal norms and behavioral intentions: stronger personal norms were associated with stronger behavioral intentions, but only when perceived behavioral control was low. Some issues evoked by these results are discussed.     

“It is Good to Know Now…Before it’s Too Late”: Promoting Sexual Health Literacy Amongst Resettled Young People With Refugee Backgrounds

Little is known about access to sexual health information amongst young people with refugee backgrounds living in countries of resettlement. This paper reports on a study of sexual health amongst recently arrived young people from refugee backgrounds in Melbourne, Australia. The study employed qualitative research methods to explore and describe how resettled youth access, interpret and implement sexual health information. Between August and December 2007, data was collected through 23 focus group discussions and 14 in-depth interviews involving 142 young people with refugee backgrounds. Participants were purposively selected to reflect the ethnic composition of humanitarian entrants to Australia over the past 3 years. Their countries of origin included Iraq, Afghanistan, Burma, Sudan, Liberia, and Horn of Africa countries. The findings highlight how young people with refugee backgrounds are disadvantaged in relation to access to sexual health information. Young people had little knowledge of sexual health or STIs apart from HIV/AIDS. While they are aware of potential sources of sexual health information, few of these sources are utilized. Specific barriers to learning about sexual health include concerns about confidentiality, shame and embarrassment when discussing sexual health, and the competing demands of resettlement. The paper argues for sexual health promotion to be an explicit part of early resettlement services for refugee youth, and the implications for the development of appropriate sexual health education programs are discussed.
