Recognizing individual faces outside one's race poses difficulty, a phenomenon known as the other-race effect. Most researchers agree that this effect results from differential experience with same-race (SR) and other-race (OR) faces. However, the specific processes that develop with visual experience and underlie the other-race effect remain to be clarified. We tested whether the integration of facial features into a whole representation-holistic processing-was larger for SR than OR faces in Caucasians and Asians without life experience with OR faces. For both classes of participants, recognition of the upper half of a composite-face stimulus was more disrupted by the bottom half (the composite-face effect) for SR than OR faces, demonstrating that SR faces are processed more holistically than OR faces. This differential holistic processing for faces of different races, probably a by-product of visual experience, may be a critical factor in the other-race effect. 相似文献

Examined a risk-resilience model of peer rejection and attention-deficit/hyperactivity disorder (ADHD) in a 5-year longitudinal study of 209 ethnically and socioeconomically diverse girls aged 6-13 at baseline and 11-18 at follow-up. Risk factors were childhood ADHD diagnosis and peer rejection; hypothesized protective factors were childhood measures of self-perceived scholastic competence, engagement in goal-directed play when alone, and popularity with adults. Adolescent criterion measures were multi-informant composites of externalizing and internalizing behavior plus indicators of academic achievement, eating pathology, and substance use. ADHD and peer rejection predicted risk for all criterion measures except for substance use, which was predicted by ADHD only. ADHD and peer rejection predicted lower adolescent academic achievement controlling for childhood achievement, but they did not predict adolescent externalizing and internalizing behavior after controlling for baseline levels of these constructs. Regarding buffers, self-perceived scholastic competence in childhood (with control of academic achievement) predicted resilient adolescent functioning. Contrary to hypothesis, goal-directed play in childhood was associated with poor adolescent outcomes. Buffers were not found to have differential effectiveness among girls with ADHD relative to comparison girls. 相似文献

Semantic priming refers to a reduction in the reaction time to identify or make a judgment about a stimulus that has been immediately preceded by a semantically related word or picture and is thought to result from a partial overlap in the semantic associates of the two words. A semantic priming lexical decision task using spoken words was presented in event-related fMRI and behavioral paradigms. Word pairs varied in terms of semantic relatedness and the connectivity between associates. Thirteen right-handed subjects underwent fMRI imaging and 10 additional subjects were tested in a behavioral version of the semantic priming task. It was hypothesized priming would be greatest, reaction time fastest, and cortical activation reduced the most for related word pairs of high connectivity, followed by related word pairs of low connectivity, and then by unrelated word pairs. Behavioral and fMRI results confirmed these predictions. fMRI activity located primarily in bilateral posterior superior and middle temporal regions showed modulation by connectivity and relatedness. The results suggest that these regions are involved in semantic processing. 相似文献

In the current set of experiments, we establish, and explore the consequences of, the imprecision that characterizes the attribute response labels typically employed in the Implicit Association Test (IAT). In Experiment 1, we demonstrate the malleability of the IAT, as conventionally implemented. IAT scores are shown to be influenced by perspective mindsets induced by an unrelated preceding task. Then, we explore how the malleability of the IAT can lead to the inference that attitude change has occurred even when there is very good reason to believe it has not (Experiment 2), and conversely, how it can obscure the detection of attitude change when such change is indeed likely to have occurred (Experiment 3). We provide conceptual explanations for these discrepancies and suggest methodological improvements to enhance the specificity of IAT measures. 相似文献

We examined associations between children’s peer relationships and (a) their parents’ social competence as well as (b) their
parents’ behaviors during the children’s peer interactions. Participants were families of 124 children ages 6–10 (68% male),
62 with ADHD and 62 age- and sex-matched comparison youth. Children’s peer relationships were assessed via parent and teacher
report, and sociometric nominations in a lab-based playgroup. Parental characteristics were assessed via parent self-report
and observations of behavior during their child’s playgroup. After statistical control of relevant covariates, parents of
children with ADHD reported poorer social skills of their own, arranged fewer playdates for their children, and displayed
more criticism during their child’s peer interaction than did parents of comparison youth. Parents’ socialization with other
parents and facilitation of the child’s peer interactions predicted their children having good peer relationships as reported
by teachers and peers, whereas parental corrective feedback to the child and praise predicted poor peer relationships. Parents’
ratings of their child’s social skills were positively associated with ratings of their own social skills, but negatively
associated with criticism and facilitation of the child’s peer interactions. Relationships between parental behaviors and
peer relationships were stronger for youth with ADHD than for comparison youth. The relevance of findings to interventions
is discussed. 相似文献

ABSTRACTThis paper studies Antoine Le Grand's account of organic identity over time in human bodies. In response to Aristotelian critics who argued that the Cartesian rejection of the Aristotelian ontology of matter and form had put in jeopardy the diachronic identity of material substances in general and of living bodies in particular, Le Grand argued that the identity over time of the human body could be accounted for without the traditional notions of matter and form. The paper shows how he drew on both the Cartesian metaphysics of mind and body and contemporary views on human anatomy and organic generation to develop a unique account of bodily identity over time in human animals. 相似文献

现代肿瘤的诊疗水平已经有了长足的进步,先进的诊断技术使得很多肿瘤得以早期发现并积极治疗,很多晚期患者也不再面临无药可用的境地,但由于临床医生的认识存在偏差,存在过度诊断和过度治疗的问题,进而给患者带来不必要的负担和痛苦。美国临床肿瘤学会(ASC0)年会上发布了一篇名为“ASCO为改善肿瘤治疗质量及医疗花费的5项建议”的文章,特别提出要重视五项临床广泛应用、花费较大,但缺乏高级临床证据的肿瘤治疗或干预措施,也提示我们需要充分评估,综合思考,为合适的患者提供正确的诊治方案,才能给患者带来更大的获益。 相似文献

This is a study of the development trend of creative scientific problem finding (CSPF) ability of a sample of 1,367 elementary, middle, and high school students in two Chinese cities. Students were instructed to generate science related questions in both open and closed conditions with responses scored for Fluency, Flexibility, and Originality. Results suggest that CSPF ability has a developmental trend characterized by a significant leap in the 5th grade, followed by a steady advance until it peaked in the 8th grade, and then declined and stabilized in the high school years (9th–11th grades). No difference between male and female students was found. The type of instruction showed significant differential influence on CSPF and its development. 相似文献

While even today lesbian, gay, bisexual and transgender people might have cause to distrust the healthcare establishment, how much more fragile was the relationship between sexual minorities and health professionals in the first decade of the AIDS epidemic. Dissent from consensus healthcare and health research then was a question of survival in the face of political and medical intransigence. This article focuses on one version of AIDS dissent: The narrative representations of AIDS in fiction by the gay African-American fantasy writer Samuel R. Delany, which rejected the rigid binarism of “safe” and “unsafe” sex practices, Delany’s evidence-based dissent. He also engaged in a related form of cultural dissent: speaking the unspeakably obscene, at a time when Silence?=?Death. Delany called into question both the inferential leaps based on limited epidemiological research that were represented in safer sex guidelines and the widespread public reticence about sexual behavior. 相似文献
