"Economic man" in cross-cultural perspective: behavioral experiments in 15 small-scale societies

Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model - based on self-interest - fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life.     

Predicting Undergraduate Condom Use with the Fishbein and Ajzen and the Triandis Attitude-Behavior Models: Implications for Public Health Interventions1

The present study used two social-psychological theories of attitude-behavior relationships to investigate condom use by college undergraduates. One purpose of the present research is to provide information for public health practitioners to better design theory-based interventions to reduce the incidence of STD's by increasing the use of condoms. Another purpose is to compare the relative usefulness of two attitude-behavior models in predicting condom use. The Fishbein and Ajzen theory of reasoned action (Ajzen, 1988; Fishbein & Ajzen. 1980) was compared with a version of Triandis' theory of attitude-behavior relations (Triandis, 1977). Of major interest was whether variables in this version of the Triandis model increased the explanatory power of the Fishbein and Ajzen model in the prediction of condom use intention and behavior. In addition, specific outcome beliefs and normative beliefs held by subjects were used to predict condom use. One hundred and ninety college undergraduates were given a questionnaire designed to measure the components of the two models. Three months after completing the questionnaire, subjects were contacted by phone to record the subject's frequency of condom use (if the subject reported having had intercourse) during the 3-month period between initial assessment and follow-up. In the prediction of intention to use a condom, results indicate that one variable from the Triandis model, personal normative beliefs, increases the explanatory power offered by the expectancy value and normative belief components of the Fishbein and Ajzen model. In the prediction of reported condom use during the 3-month follow-up period, two variables from the Triandis model—perceived susceptibility and AIDS fear—significantly increased the predictive power of the Fishbein and Ajzen model. Based on these results, the authors propose an alternative model to explain undergraduate condom use. The implications of these findings for public health interventions to encourage the use of condoms is discussed.     

9 Suicide in San Francisco,CA: A Comparison of Caucasian and Asian Groups, 1987–1994

Completed suicides in the city of San Francisco, California, were examined across all ages in the racial groups of Caucasians (n = 798) and Asians (n = 124) from 1987 to 1994. A comparison of Caucasians and Asians showed that there were differences between them in their rates across all age groups. The major findings are: (1) Caucasians predominately used gunshot to complete suicide whereas Asians predominately used hanging to complete suicide, (2) Asian women over the age of 85 have the highest rates across both groups and genders, (3) Asians, as compared to Caucasians, used fewer drugs and alcohol at time of death. Theoretical connections between differences in suicide and definition of the self, as influenced by culture, are discussed.
