Trust,social categories,and individuals: The case of gender

While the cooperate vs. defect choice in the prisoner's dilemma is not an appropriate paradigm for the study of trust and trusting behavior, the play vs. not play choiceis. We show that femalesas a category are more trusted to cooperate — by both male and female judges — than males. Yet neither male nor female judges use gender to predict cooperation from particular individuals (trust) or as a criterion for choosing to play (trusting behavior) when they have the option of not playing particular prisoner's dilemma games. Further, in our experimental context, female and male did not differ in their cooperation rates. We speculate (a) that subjects' generalized expectations are a response to gender-based role differences outside the laboratory, (b) that subjects' failure to make individual-by-individual discriminations by gender is a response to the fact that the experimental context made such natural-world roles irrelevant, and (c) that our findings about the irrelevance of genderper se in trusting relationships will be true for other social categoriesper se.The research reported in this paper was supported by the National Science Foundation grant SES-9008157 to Orbell and Dawes; any opinions, conclusions or recommendations are those of the authors and do not necessarily reflect the views of the National Science Foundation.

Cyborg Identities and the Relational Web: Recasting 'Narrative Identity' in Moral and Political Theory

Current debates surrounding liberalism and communitarianism, modernity and postmodernity, ethical theory and narrative ethics fail to account for shifting foundations of personal identity in an increasingly computer-mediated era of human communication. This paper aims to examine some of the conceptual assumptions about identity and community which are being radically undermined by rapidly evolving information networks and are therefore in need of redefinition. Additionally, I argue for an expansion of the literary imagination to include virtual, coauthored fiction sites where exploration of personal identity will bear upon future ethical and political decision-making.     

Case vignette: to share or not to share

For years, the notion that researchers should share data freely with fellow scientists has been discussed widely. Some argue that this is especially true when the data are generated in federally funded projects. A recent provision in the reauthorization bill for the National Institutes of Health (NIH) would ensconce this principle in law. NIH grantees would be required, on demand, to furnish their data to other researchers. According to the proposed legislation, research data would have to be preserved and made avilable for 3 years after the completion of a project, and for 5 years following publication of the results in a scientific journal. One objective, according to a congressional aide, would be to make it easier for scientists with dissenting views to obtain and reanalyze data collected with public funds. It would also facilitate publication of alternative analyses. Personal records and patent applications would be exempted, but other data from clinical, behavioral, or epidemiological research focused on the evaluation or efficacy of a drug, medical device, or treatment of any sort would be covered immediately. Is such mandatory sharing of data ethical and appropriate scholarship? Does it raise potential for abuse? Should colleagues be required to provide such access to data, whether or not federal support was used in its collection?     

Gender differences in parent-child conversations about past emotions

In this study, we examined the emotional content of parents’ conversations about past events with their 40-month-old children. Subjects were 24 white middle-class children and their mothers and fathers. At separate home visits, each parent independently engaged the child in conversation about three events that parent and child had experienced together only once before. Mothers and fathers talked about emotional aspects of events in similar ways, but they both used a greater number and variety of emotion words with daughters than with sons. Parents also mentioned sad aspects of events more with daughters than with sons. Implications of the differential socialization of emotion for boys and girls are discussed.     

Illusion magnitude as a function of visual field exposure

Forty-eight right-handed subjects divided into four groups, each consisting of six males and six females, were employed in an investigation of cerebral hemispheric influence on the perception of tachistoscopically presented simultaneous and successive versions of the Mueller-Lyer figure. The simultaneous version exposed in the left visual field resulted in a larger effect than did right visual field exposures. The successive version exposed in the right visual field resulted in a larger illusion magnitude than it did in the left visual field. The magnitude of visual field differences in response to the successive version was greater than visual field differences found in response to the simultaneous version     

Recollection and familiarity in recognition memory: adult age differences and neuropsychological test correlates

Dual process theories account for age-related changes in memory by proposing that old age is associated with deficits in recollection together with invariance in familiarity. The authors evaluated this proposal in recognition by examining recollection and familiarity estimates in young and older adults across 3 process estimation methods: inclusion/exclusion, remember/know, and receiver operating characteristics (ROC). Consistent with a previous literature review (Light, Prull, LaVoie, & Healy, 2000), the authors found age invariance in familiarity when process estimates were derived from the inclusion/exclusion method, but the authors found age differences favoring the young when familiarity estimates were derived from the remember/know and ROC methods. Recollection estimates were lower for older adults in all 3 methods. Recollection and familiarity had variable relationships with frontal- and temporal-lobe measures of neuropsychological functioning in older adults, depending on which method was used to generate process estimates. These data suggest that although recollection deficits appear to be the rule in aging, not all estimates of familiarity show age invariance.     

Externalizing and personalizing biases in persecutory delusions: the relationship with poor insight and theory-of-mind

The presence of externalizing bias (EB) for negative events together with personalizing bias (PB) (a bias to blame others rather than circumstances) may jointly constitute a vulnerability to develop persecutory delusions (PDs). Whereas EB purportedly serves to defend a vulnerable self-concept by avoiding negative self-attributions and might therefore exacerbate poor insight, PB may reflect cognitive deficits, including theory-of-mind impairment. We investigated these proposals in 34 schizophrenic patients with a history of PDs and 21 healthy controls. Patients with moderate- to severe-PDs and patients without a current PD showed excessive EB which was, surprisingly, absent in patients with mild persecutory delusions (mild-PDs). That EB might wax and wane with fluctuating delusional intensity was interpreted in accord with a new dynamic model of attribution self-representation cycles. As predicted, EB exacerbated poor insight. However, counter to predictions, theory-of-mind impairment did not increase PB, which was marked in all participants, whether clinical or non-clinical; instead, theory-of-mind impairment was also correlated with poor insight. Our findings indicate multiple pathways to poor insight, one of which is a theory-of-mind difficulty, impairing the capacity to simulate other perspectives for the purpose of critically evaluating one's own beliefs and circumstances.     

Bring It On: Proactive Coping with Discrimination

We investigated proactive coping with discrimination among heavy women in both a high impact lab study (101 women) and a daily diary study (62 women). Heavy women assessed greater harm and fewer coping resources for discriminatory, as compared to non-discriminatory, hassles (Study 2). Primary appraisals of harm were important determinants of proactive coping, including primary control (attempts to change the environment) and secondary control (attempts to change the self to fit the environment) directed at discriminatory stressors (Studies 1 and 2). When heavy women used primary control coping efforts, they experienced positive interpersonal outcomes (Study 1) and less negative intrapersonal outcomes (Study 2). We discuss the benefits and limitations of engaging in proactive coping and suggest avenues for future research.
