Adults' face processing may be specialized for the dimensions of young adult faces. For example, young and older adults exhibit increased accuracy in normality judgments and greater agreement in attractiveness ratings for young versus older adult faces. The present study was designed to examine whether there is a similar young adult face bias in facial age estimates. In Experiment 1, we created a face age continuum by morphing an averaged young adult face with an averaged older adult face in 5% increments, for a total of 21 faces ranging from 0 to 100% old. Young and older adults estimated facial age for three stimulus age categories [young (morphs 0–30%), middle‐aged (morphs 35–65%), and older adult (morphs 70–100%)]. Both age groups showed the least differentiation in age estimates for young adult faces, despite showing greater consensus across participants in estimates for young faces. In Experiment 2, young and older adults made age estimates for individual young and older adult identities. Both age groups were more accurate and showed greater consensus in age estimates for young faces. Collectively, these results provide evidence for a bias in processing young adult faces beyond that which is often observed in recognition and normality/attractiveness judgment tasks.  相似文献

This prospective cohort study used administrative data from the Army Study to Assess Risk and Resilience in Servicemembers to examine associations between neurocognitive functioning and subsequent suicidal events among Regular Army enlisted soldiers during the years 2004–2009. Cases were all soldiers who completed the Army's Automated Neuropsychological Assessment Metrics (ANAM) computerized testing battery prior to documented suicide attempt (n = 607), ideation (n = 955), or death (n = 57). Controls were an equal‐probability sample of 9,893 person‐months from other soldiers. Exploratory factor analysis of five ANAM tests identified a general neurocognitive factor that excluded the mathematic processing test (MTH). When examined separately in logistic regression analyses that controlled for sociodemographics and prior mental health diagnosis, both the general neurocognitive factor (logit [β] = ?.197 to ?.521; < .01) and MTH (β = ?.024 to ?.064; < .05) were associated with all outcomes. When both predictors were examined simultaneously, the general neurocognitive factor continued to be associated with all outcomes (β = ?.164 to ?.417; < .05) and MTH continued to be associated with suicide attempt (β = ?.015; = .046) and ideation (β = ?.014; = .018). These small but robust associations suggest that future research must continue to examine the extent to which objective neurocognitive tests may enhance understanding and prediction of suicide risk.  相似文献

There is little known about Hong Kong juvenile offenders on probation. The purpose of this study was to compare Hong Kong juvenile violent with non-violent probationers on static demographic and psychological variables. The study comprised 109 male juvenile probationers aged 14-20 years (M = 16.97, SD = 1.44) in community transitional housing; 34 were adjudicated for violent offenses, while 75 were non-violent. The Rosenberg Self-Esteem Scale (RSES), Satisfaction with Life Scale (SWLS), Social Bonding Scale-Theft (SBS-T), Social Bonding Scale-Violent Crime (SBS-VC), Positive and Negative Affect Scales (PANAS), Impulsiveness Scale-Short Form (IS-SF) and CRIME-PICS II were administered to measure self-esteem, life satisfaction, social bond, positive and negative affect, impulsivity, pro-offending attitudes, and self-perceived life problems. Data on onset age of delinquent behavior, age of first adjudication, number of prior adjudications, and frequency of self-reported delinquency in the past year were also collected. t-tests were consistent with significant differences for violent offenders including higher self-esteem (p < 0.05). Non-violent offenders self-reported significantly more theft (p < 0.05) with a tendency to deny victim hurt more often (p < 0.01); 76.5% of violent offenders self-reported both violent and non-violent crime, while 58.7% of non-violent offenders reported only non-violent crime. For violent and non-violent offenders, the onset of delinquency was inversely related to the frequency of self-reported delinquency. Using ordinary least-squares (OLS) regression analyses, self-anticipated violent reoffending risk was predicted by age of onset, frequency of self-reported delinquency, social bond (inversely), and impulsivity, while non-violent reoffending risk was predicted by the number of prior convictions and self-reported delinquency. Only two psychological correlates, social bond and impulsivity, were related to violent delinquency; interventions are suggested.  相似文献

Meditation may show differential effects on stress and plasma catecholamines based on genetic polymorphisms in brain-derived neurotrophic factor (BDNF) and catechol O-methyl transferase (COMT). Eighty adults (40 men, 40 women; mean age 26 years) who practiced meditation regularly and 57 healthy control adults (35 men, 22 women; mean age 26 years) participated. Plasma catecholamines (norepinephrine (NE), epinephrine (E), and dopamine (DA)) concentrations were measured, and a modified form of the Stress Response Inventory was administered. The results were analyzed using two-way analysis of covariance (ANCOVA) with control and meditation subjects, gene polymorphism as factors, and meditation duration as the covariate. Two-way ANCOVA showed a significant interaction between control and meditation subjects, and BDNF Val66Met polymorphism on DA/NE+DA/E (p = 0.042) and NE/E+NE/DA (p = 0.046) ratios. A significant interaction was found for control and meditation subjects with COMT Val158Met polymorphism and plasma NE concentrations (p = 0.009). Post hoc ANCOVA in the meditation group, adjusted for meditation duration, showed significantly higher plasma NE concentrations for COMT Met carriers than COMT Val/Val subjects (p = 0.025). Significant differences of stress levels were found between the control and meditation subjects in BDNF Val/Met (p < 0.001) and BDNF Met/Met (p = 0.003), whereas stress levels in the BDNF Val/Val genotype did not differ between the control and meditation groups. This is the first evidence that meditation produces different effects on plasma catecholamines according to BDNF or COMT polymorphisms.  相似文献

Perceptions of coronary heart disease (CHD) influence individual health behavior, which is central to preventing the disease. Not enough is known about the demographic differences in perceptions of CHD among Chinese communities. This study examined these differences in the perceived seriousness and risk of CHD among Hong Kong Chinese. A self-developed questionnaire was administered to a convenient sample (n = 236). Significant differences were identified in the perceived seriousness and risk of CHD between younger and older age groups (p < 0.001) and groups with lower and higher education levels (p < 0.001), but not between genders (p > 0.05). Over 50% of participants expressed greater concern about infectious disease than about CHD, while two-thirds to over half of female, older, and less educated participants were more concerned about stroke. This study highlighted populations with lower levels of CHD perception that need increased public education. The findings have implications for the societal readiness to establishing ongoing public healthcare strategies to increase awareness of CHD.  相似文献

We propose a person-centered framework for conceptualizing subjective careers in an increasingly boundaryless work context. Specifically, we argue that entrepreneurship, professionalism, and leadership (EPL) can serve as three key dimensions of subjective career space. We relate this framework to earlier macro-level national and organizational career models proposed by Kanter (1989) and Schein (1978). Our empirical study involving 10,326 Singaporean university students demonstrated that entrepreneurial, professional, and leadership career aspirations (including motivations, efficacies, and intentions) can be measured independently, that these career dimensions are independent of vocational interests, and that they are to some degree viewed as competing career alternatives. We also show that EPL motivation profiles can operationalize the boundaryless and protean career concepts. Individuals concurrently high in entrepreneurial, professional, and leadership career motivations, and those high in entrepreneurial and leadership motivations are highest in boundaryless and self-directed career attitudes, while those primarily motivated for professional careers hold the most traditional career attitudes. We conclude by discussing the potential of the framework for understanding human resource issues at organizational and national levels and for enhancing the study of entrepreneurship, professionalism, and leadership.  相似文献

This study examined gender differences in covert fidelity management among dating individuals in China. Fidelity management refers to tactics and behaviors people use to monitor their partners’ fidelity. Two hundred and thirty two young adults (18–26?years old, M?=?23.44, SD?=?1.93) primarily from the cities of Beijing, Wuhan, Dalian, and Guangzhou in mainland China completed a questionnaire designed to measure self-esteem, trust, peer influence, relationship satisfaction and covert fidelity management. Consistent with our hypothesis, women were found to engage in more covert fidelity management than men. Regression results revealed that for both women and men, trust and peer influence were significant predictors of covert fidelity management behavior. However, self-esteem was a significant predictor of men’s covert fidelity management, not women’s. Furthermore, covert fidelity management was found not related to women’s relationship satisfaction, but was significantly associated with men’s satisfaction in a negative direction. These findings have interesting implications for understanding romantic partners’ behaviors in infidelity-related situations.  相似文献

This study reports preliminary psychometric findings for a seven-item religiosity scale in a community-based sample of Vietnamese Americans ages 18 to 83 years (N = 119; 58% women, 42% men). A bilingual survey was distributed to Vietnamese who were evacuated during Hurricane Katrina and had returned after the disaster. Internal consistency, factorial structure validity, and criterion validity were evaluated on the scale items. The bilingual scale had good internal consistency. While exploratory and confirmatory factor analysis results provided support for a two-factor structure which captured Religious Involvement and Religious Coping, a one-factor model had slightly better fit. Individuals who scored high on the religiosity scale reported a significantly lower score on their stressful experiences during the hurricane, providing evidence of criterion validity.  相似文献
