Individuals with developmental prosopagnosia (DP) have a severe difficulty recognizing the faces of known individuals in the absence of any history of neurological damage. These recognition problems may be linked to selective deficits in the holistic/configural processing of faces. We used two‐tone Mooney images to study the processing of faces versus non‐face objects in DP when it is based on holistic information (or the facial gestalt) in the absence of obvious local cues about facial features. A rapid adaptation procedure was employed for a group of 16 DPs. Naturalistic photographs of upright faces were preceded by upright or inverted Mooney faces or by Mooney houses. DPs showed face‐sensitive N170 components in response to Mooney faces versus houses, and N170 amplitude reductions for inverted as compared to upright Mooney faces. They also showed the typical pattern of N170 adaptation effects, with reduced N170 components when upright naturalistic test faces were preceded by upright Mooney faces, demonstrating that the perception of Mooney and naturalistic faces recruits shared neural populations. Our findings demonstrate that individuals with DP can utilize global information about face configurations for categorical discriminations between faces and non‐face objects, and suggest that face processing deficits emerge primarily at more fine‐grained higher level stages of face perception.  相似文献

This study aims at exploring the decision-making process involved in third-party punishment (TPP) within an economic frame, using the TPP game. We investigated altruistic punishment, that is, the behaviour of spending one's own money, with no personal gain, to punish those who violate the norms of cooperation. We analysed this behaviour, in an in-group and out-group game setting, to compare how individuals behave with members of their own group (in-group) and with members of another group (out-group). In particular, groups were defined on a real nationality basis (Chinese or Italian). Our results showed altruistic punishment behaviour in both experimental groups and this tendency emerged as more prominent when faced with unfair play towards a member of one's own group. Furthermore, both groups exhibited a propensity for anti-social punishment behaviour: many participants spent small amounts of money to punish fair behaviour, regardless of national group membership.  相似文献

Adolescents with conduct disorder (CD) and elevated callous-unemotional (CU) traits have been reported to present with a more severe and persistent pattern of antisocial behaviour than those with low levels of CU traits. However, relatively few studies have investigated whether there are differences in brain structure between these subgroups.We acquired diffusion tensor imaging data and used tract-based spatial statistics (TBSS) to compare adolescents with CD and high levels of CU traits (CD/CU+; n?=?18, CD and low levels of CU traits (CD/CU-; n?=?17) and healthy controls (HC; n?=?32) on measures of fractional anisotropy (FA), axial (AD), radial (RD) and mean (MD) diffusivity. Compared to CD/CU- adolescents, those with CD/CU+ presented increased FA and reduced RD and MD (lower diffusivity) in several tracts including: body and splenium of the corpus callosum, right inferior longitudinal fasciculus, ILF; right inferior fronto-occipital fasciculus, IFOF; left superior longitudinal fasciculus, SLF; left cerebral peduncle, bilateral internal capsule, left superior and posterior corona radiata, bilateral thalamic radiation and left external capsule. In addition, relative to CD/CU- individuals, adolescents with CD/CU+ showed lower diffusivity (indexed by reduced RD and MD) in left uncinate fasciculus and bilateral fornix. Finally, relative to healthy controls, CD/CU+ individuals showed lower diffusivity (reduced RD) in the genu and body of the corpus callosum and left anterior corona radiata. These results suggest that CD/CU+ individuals present with white-matter microstructural abnormalities compared to both CD/CU- individuals and age-matched healthy controls. This finding is consistent with emerging evidence suggesting that CD/CU+ represents a distinct subtype of CD, and illustrates the importance of accounting for heterogeneity within CD populations.  相似文献

This article provides a review of the literature on the educational and career development of women of color within the context of social cognitive career theory (Lent, et al, 1994 and Lent, et al, 1996). Specifically, possible gender, ethnic, racial, and cultural influences on career self-efficacy and outcome expectations are explored to delinate the potential mechanisms whereby ethnicity, culture, and ethnic and racial identity development, in interaction with gender, affect career choice and adjustment. Suggestions for future research on social cognitive career theory and the career development of women of color are presented.  相似文献

Substance use may influence mothers’ responsiveness to their infants and negatively impact the parent–infant relationship. Maternal substance use may co-opt neural circuitry involved in caregiving, thus reducing the salience of infant cues and diminishing the sense of reward experienced by caring for infants. Gaps in understanding exist with regard to the mechanisms by which substance use operates to influence mothers’ processing of infant cues and how this translates to caregiving. Therefore, we examined how substance use might relate to maternal neural responses to infant cues using event-related potentials (ERPs). Substance-using (n = 29) and nonsubstance-using (n = 29) mothers viewed photographs of infant faces and heard recordings of infant vocalizations while electroencephalography was recorded simultaneously. Three specific ERP components were used to examine initial processing of infant faces (N170) and cries (N100), and attentional allocation to infant faces and cries (P300). Substance-using mothers did not discriminate facial affect at early encoding stages (N170), were generally slower to orient to infant cries (N100), showed heightened responses to neutral faces (P300), and failed to adaptively differentiate between high-distress versus low-distress cries (P300). These differences may be important to caregiving behaviors associated with the formation of mother–child attachment. Implications are discussed, as are limitations and future directions.  相似文献

Lockdown drills are used in pre-K–12 public schools throughout the country; however, little research exists regarding their impact on students and school staff (Ilk, 2018). Because of school counselors' role in both prevention of and response to school gun violence (American Counseling Association, 2018), we used a phenomenological approach to investigate their experiences with lockdown drills (N = 26). Results included the following three themes: (a) school counselors' sense of duty to follow school protocol, (b) unintended emotional consequences related to lockdown drills, and (c) school counselors navigating complexities. Implications for school counselors and corresponding school procedures are discussed.  相似文献

The positive affect and negative affect schedule (PANAS) is a popular measure of positive (PA) and negative affectivity (NA). Developed and validated in Western contexts, the 20‐item scale has been frequently administered on respondents from Asian countries with the assumption of cross‐cultural measurement invariance. We examine this assumption via a rigorous multigroup confirmatory factor analysis, which allows us to assess between‐group differences in both strength of scale item‐to‐latent factor relationship (metric invariance test) and mean of each scale item (scalar invariance test), on a large sample of 1,065 respondents recruited from Singapore (Asian sample) and the United States (Western sample). We found that two items assessing PA (“excited” and “proud”) and three items assessing NA (“guilty,” “hostile,” and “ashamed”) exhibited metric noninvariance whereas 11 of the remaining metric invariant items exhibited scalar noninvariance, suggesting that the PA and NA constructs differ from what the PANAS is expected to measure for Asian respondents. Our findings serve as a cautionary note to researchers who intend to administer the PANAS in future studies as well as to researchers interpreting the results of past studies involving respondents from Asian countries.  相似文献

This study investigates word‐of‐mouth (WOM) information processing routes from active WOM seeking behaviour. Employing the elaboration likelihood model (ELM), the direct and indirect effects of factors within information processing routes are examined in a credence service context. A deeper exploration of the causal chains of each route was conducted using serial mediation models of message quality and source characteristics. Data were collected in the higher education context from a survey of 509 high school students applying for tertiary study. Findings indicate that active WOM seeking and the serial mediation effects elicit two routes of information processing: central and peripheral. This study is amongst the first to intensively reveal the underlying causal chains of WOM processing and supports the application of ELM theory in WOM research.  相似文献

An increasing number of immigrant students attend Italian schools, with the possibility of being involved in bullying episodes. A few studies have investigated this phenomenon, providing some evidence that immigrant students may face an increased risk of being bullied compared to native-born students. The present study adopted a mixed-method design, which may better detect the dynamics of bullying towards immigrant peers. Participants were 692 native-born and immigrant students (20.5% with immigrant background; 54.8% females) who filled in self-report measures about their bullying experiences, popularity, acceptance of diversity at school, and prejudice. Thirty-five pupils (54% with immigrant background) were also interviewed. Two hypothetical bullying scenarios were presented: one depicting a native-born victim and one depicting an immigrant victim. After each scenario, adolescents were encouraged to reason about the motives for bullying. Quantitative data showed that general bullying was associated with perceived popularity status among peers, while racial bullying was associated with prejudice but not peer status. The relevance of anti-immigrant prejudices in driving racial bullying emerged also from adolescents’ interviews. The qualitative data indicated that among the reasons for bullying, adolescents mentioned a desire for dominance and popularity, in particular when the victim was non-immigrant. Findings suggest that, in addition to individual and peer group-related risk factors, prejudice also needs to be addressed in anti-bullying interventions aimed to counteract racial bullying.  相似文献

The relationship between possible selves and boredom in juvenile delinquency was examined in 418 high school students. The construct Possible Selves refers to the representation of the self that each person would like to become, could become, and is afraid of becoming. Participants who acknowledged high levels of delinquent behaviors reported more negative possible selves, a higher tendency to experience boredom, and fewer positive possible selves than did adolescents who engaged in lower levels of delinquent behaviors. Also, the number of negative possible selves, the number of positive possible selves, boredom proneness, and gender accounted for 32% of the variance in juvenile delinquency. Overall, the results provide evidence that boredom and a negative view of one's future play a significant role in adolescent delinquent behavior.  相似文献
