An estimate of someone's IQ is a potentially informative personal datum. This study examines the association between external skull measurements and IQ scores, and uses the resulting regression equation to provide an estimate of the IQ of King Robert I of Scotland (Robert Bruce, 1274–1329). Participants were 48 relatively healthy Caucasian men (age 71–76 years) resident in Scotland. Using magnetic resonance imaging data, intracranial volume estimated from external skull length and width correlated greater than .5 (p < .001) with measured intracranial area, which correlates very highly with brain volume. IQ scores estimated from the National Adult Reading Test (NART) correlated .56 (p < .001) with measured intracranial area, and .49 (p < .01) with estimated intracranial volume based on external skull width and length. The partial correlation coefficient of this latter association was .25 (p = .09) after adjustment for measured intracranial area. Thus, actual intracranial area accounts for about 74% of the variance shared by NART and estimated intracranial volume. A cast of the skull of Robert Bruce was measured and its intracranial volume estimated. A regression equation between IQ and estimated intracranial volume, based on data from the 48 subjects, estimated the IQ of Robert Bruce at about 128 (95% confidence interval 106 to 130), i.e. almost two standard deviations above the mean. NART scores show a ceiling effect, so this estimated IQ might be an underestimate. Robert Bruce's estimated high IQ is congruent with his military, political and other intellectual achievements. 相似文献

Confident witnesses are deemed more credible than unconfident ones, and accurate witnesses are deemed more credible than inaccurate ones. But are those effects independent? Two experiments show that errors in testimony damage the overall credibility of witnesses who were confident about the erroneous testimony more than that of witnesses who were not confident about it. Furthermore, after making an error, less confident witnesses may appear more credible than more confident ones. Our interpretation of these results is that people make inferences about source calibration when evaluating testimony and other social communication. 相似文献

This paper examines the nature of the harm-benefit tradeoff in early clinical research for interventions that involve remote possibility of direct benefit and likelihood of direct harms to research participants with fatal prognoses, by drawing on the example of gene transfer trials for glioblastoma multiforme. We argue that the appeal made by the component approach to clinical equipoise fails to account fully for the nature of the harm-benefit tradeoff-individual harm for social benefit-that would be required to justify such research. An analysis of what we label "collateral affective benefits," such as the experience of hope or exercise of altruism, shows that the existence of these motivations reinforces rather than mitigates the necessity of justification by reference to social benefit. Evaluations of social benefit must be taken seriously in the research ethics review process to avoid the exploitation of research participants' motivations of hope or altruism and to avoid the possibility of inadvertent exploitation of high-risk research participants and the harms that would associate with such exploitation. 相似文献

This paper investigates whether social anxiety and loneliness lead to contrasting beliefs and preferences among cell phone users towards texting and talking on their cell phones. Three hypotheses are examined: (1) that social anxiety and loneliness are differentially associated with generalized preferences either for texting or for talking on the cell phone, (2) that these preferences are linked to contrasting beliefs concerning the social functionality of the short message service (SMS), and (3) that these divergent beliefs mediate the effects of social anxiety and loneliness on cell phone users' generalized preferences for texting or talking. Results from an Internet questionnaire (N=158) showed that, whilst lonely participants preferred making voice calls and rated texting as a less intimate method of contact, anxious participants preferred to text, and rated it a superior medium for expressive and intimate contact. These divergent beliefs accounted for 36% and 16% of the variance in preference for texting and voice calls, respectively, and significantly attenuated the influence of loneliness and social anxiety when they were added to the regression equations for these measures. Results are discussed in terms of the hyperpersonal possibilities of mobile communications technologies. 相似文献

We examined reactivity of staff behavior to observations of their work performance. After training 2 job coaches to reduce completion of break activities for supported workers, we evaluated job-coach behavior using both conspicuous and inconspicuous observations. Results indicated that both coaches completed none of the activities when observations were conspicuous but most of the activities when observations were inconspicuous. Subsequently, job coaches were taught to self-record their performances, and their completion of activities remained low with inconspicuous observations. Implications of reactivity are discussed for investigations that target staff behavior. 相似文献

A policy of inclusion has focused the 'gaze' of the UK government toward youth services and resulted in the development of the Connexions service in England. Within that context, the practice and professional identity of careers advisers (now called personal advisers) has changed. Many are working intensively with so-called 'harder-to-help' young people in 'challenging' situations where support and supervision appears to be essential. This paper discusses the findings from a qualitative case study, which sought to question that need and to investigate the perceived purpose of support and supervision. The study explored these perspectives with the aim of foregrounding differences and similarities. It is not suggested that the themes discussed are fixed; however, the discourse of practitioners needs to be heard and not silenced by louder definitions about purpose. The findings, however tentative, may be pertinent for circumstances where guidance and counselling are seen as relevant activities for the promotion of social inclusion. 相似文献

ABSTRACT— When several choice options are sampled one at a time in a sequence and a single choice of the best option is made at the end of the sequence, which location in the sequence is chosen most often? We report a large-scale experiment that assessed tasting preferences in choice sets of two, three, four, or five wines. We found a large primacy effect—the first wine had a large advantage in the end-of-sequence choice. We also found that participants who were knowledgeable about wines showed a recency effect in the longer sequences. We conclude with a process model that explains our findings. 相似文献

Congruence in spirituality between HIV+ adolescent (n = 40)/family (n = 40) dyads and psychological adjustment and quality of life were assessed, using the Spiritual Well-Being Scale of the Functional Assessment of Chronic Illness Therapy, Beck Depression Inventory-II, Beck Anxiety Inventory and Pediatric Quality of Life Inventory at baseline and 3-month post-intervention. Adolescents were 60 % female and 92 % African American. Congruence in spirituality between adolescent/surrogate dyads remained unchanged at 3 months. High congruence existed for “having a reason for living”; rejection of “life lacks meaning/purpose” and “HIV is a punishment from God.” Adolescents were less likely to forgive the harm others caused them than their families. 相似文献

This study examined the association between political ideology and linguistic indicators of integrative complexity and opinion leadership in U.S. political blog posts (N = 519). Using Linguistic Inquiry and Word Count (LIWC) text analysis, we found that the posts of conservative bloggers were more integratively simple than those of liberal bloggers. Furthermore, in support of a proposed opinion leadership model of integrative complexity, the relationship between ideology and integrative complexity was mediated by psychological distancing (an indicator of a hierarchical communication style). These findings demonstrate an ideological divide in the extent to which the blogosphere reflects deliberative democratic ideals. 相似文献
