Individuals with psychopathy are often characterized by emotional processing deficits, and recent research has examined the specific contexts and cognitive mechanisms that underlie these abnormalities. Some evidence suggests that abnormal features of attention are fundamental to emotional deficits in persons with psychopathy, but few studies have demonstrated the neural underpinnings responsible for such effects. Here, we use functional neuroimaging to examine attention–emotion interactions among incarcerated individuals (n = 120) evaluated for psychopathic traits using the Hare Psychopathy Checklist–Revised (PCL-R). Using a task designed to manipulate attention to emotional features of visual stimuli, we demonstrate effects representing implicit emotional processing, explicit emotional processing, attention-facilitated emotional processing, and vigilance for emotional content. Results confirm the importance of considering mechanisms of attention when evaluating emotional processing differences related to psychopathic traits. The affective-interpersonal features of psychopathy (PCL-R Factor 1) were associated with relatively lower emotion-dependent augmentation of activity in visual processing areas during implicit emotional processing, while antisocial-lifestyle features (PCL-R Factor 2) were associated with elevated activity in the amygdala and related salience network regions. During explicit emotional processing, psychopathic traits were associated with upregulation in the medial prefrontal cortex, insula, and superior frontal regions. Isolating the impact of explicit attention to emotional content, only Factor 1 was related to upregulation of activity in the visual processing stream, which was accompanied by increased activity in the angular gyrus. These effects highlight some important mechanisms underlying abnormal features of attention and emotional processing that accompany psychopathic traits. 相似文献

Before alcohol was generally known to cause birth defects, NIAAA in 1974 began funding a population-based Seattle study on
alcohol use and pregnancy outcome. Women receiving prenatal care by mid-pregnancy were recruited (N = 1,529) and interviewed at home. Approximately 500 offspring exposed to a range of alcohol levels were examined on 11 occasions
between day 1 and 25 years. Neuropsychological and neurobehavioral performance measures are correlated with prenatal alcohol
dose, without substantial confounding by socio-demographic or rearing conditions, smoking, nutrition, or other drugs. Deficits
in attention, arithmetic skill, spatial-visual memory, and IQ, as well as increased alcohol problems and psychiatric disorders
are among offspring outcomes correlated at several ages with maternal drinking during and before pregnancy recognition. Findings
are not confined to women who believed they had alcohol problems. Not all exposed offspring appear affected. 相似文献

This study investigated factors associated with social anxiety during early adolescence using multiple informants, including
self and peer perspectives, teacher ratings, and direct observations. Negative social performance expectations, maladaptive
coping strategies, and social skill deficits were examined as correlates of social anxiety and mediators linking social anxiety
with poor peer relations. Participants were 84 middle school students (47 girls, 37 boys) over-sampled for elevated social
anxiety. Analyses revealed correlations linking social anxiety with decreased peer acceptance and increased peer victimization.
Path analysis indicated that negative social performance expectations and social withdrawal-disengagement accounted for the
association between social anxiety and decreased peer acceptance. Social anxiety, self-directed coping strategies, and social
withdrawal-disengagement were each directly linked with increased peer victimization for boys. The results replicate findings
based on clinical samples, extend understanding of cognitive, social, and behavioral factors associated with social anxiety
in middle school, and provide new information regarding gender differences in the correlates of social anxiety. 相似文献

The study examined whether relationships with extended kin were related to higher levels of mental health and academic functioning among college students. Specifically, the study tested whether perceived emotional support from extended (non-nuclear) family was related to self-esteem, psychological distress, and academic efficacy and dedication above and beyond relationships with one’s primary caregivers, and whether these associations varied by class year in college. The sample consisted of 530 students (average age = 20.82), at a public, four-year university. The results revealed that freshmen and seniors who reported high levels of positive relationships with their extended kin also reported higher levels of academic-efficacy and dedication, as well as lower levels of psychological distress. However, the relation between kin emotional support and these outcomes were not significant for sophomores and juniors. There was also a significant association between kinship support and self-esteem for participants in all four class levels. The study underscores the need to examine extended social support systems among college students, above and beyond those maintained with primary caregivers, as well as the dynamic nature of family support during young adulthood. 相似文献

The AGM theory of belief revision provides a formal framework to represent the dynamics of epistemic states. In this framework,
the beliefs of the agent are usually represented as logical formulas while the change operations are constrained by rationality
postulates. In the original proposal, the logic underlying the reasoning was supposed to be supraclassical, among other properties.
In this paper, we present some of the existing work in adapting the AGM theory for non-classical logics and discuss their
interconnections and what is still missing for each approach. 相似文献

Do philosophy professors specializing in ethics behave, on average, any morally better than do other professors? If not, do they at least behave more consistently with their expressed values? These questions have never been systematically studied. We examine the self-reported moral attitudes and moral behavior of 198 ethics professors, 208 non-ethicist philosophers, and 167 professors in departments other than philosophy on eight moral issues: academic society membership, voting, staying in touch with one's mother, vegetarianism, organ and blood donation, responsiveness to student emails, charitable giving, and honesty in responding to survey questionnaires. On some issues, we also had direct behavioral measures that we could compare with the self-reports. Ethicists expressed somewhat more stringent normative attitudes on some issues, such as vegetarianism and charitable donation. However, on no issue did ethicists show unequivocally better behavior than the two comparison groups. Our findings on attitude-behavior consistency were mixed: ethicists showed the strongest relationship between behavior and expressed moral attitude regarding voting but the weakest regarding charitable donation. We discuss implications for several models of the relationship between philosophical reflection and real-world moral behavior. 相似文献
