What happens in the brain when we reach or exceed our capacity limits? Are there individual differences for performance at capacity limits? We used functional magnetic resonance imaging (fMRI) to investigate the impact of increases in processing demand on selected cortical areas when participants performed a parametrically varied and challenging dual task. Low-performing participants respond with large and load-dependent activation increases in many cortical areas when exposed to excessive task requirements, accompanied by decreasing performance. It seems that these participants recruit additional attentional and strategy-related resources with increasing difficulty, which are either not relevant or even detrimental to performance. In contrast, the brains of the high-performing participants “keep cool” in terms of activation changes, despite continuous correct performance, reflecting different and more efficient processing. These findings shed light on the differential implications of performance on activation patterns and underline the importance of the interindividual-differences approach in neuroimaging research.  相似文献

Studies using facial emotional expressions as stimuli partially support the assumption of biased processing of social signals in social phobia. This pilot study explored for the first time whether individuals with social phobia display a processing bias towards emotional prosody. Fifteen individuals with generalized social phobia and fifteen healthy controls (HC) matched for gender, age, and education completed a recognition test consisting of meaningless utterances spoken in a neutral, angry, sad, fearful, disgusted or happy tone of voice. Participants also evaluated the stimuli with regard to valence and arousal. While these ratings did not differ significantly between groups, analysis of the recognition test revealed enhanced identification of sad and fearful voices and decreased identification of happy voices in individuals with social phobia compared with HC. The two groups did not differ in their processing of neutral, disgust, and anger prosody.  相似文献

A model of business success was developed with motivational resources (locus of control, self-efficacy, achievement motivation, and self-reported personal initiative) and cognitive resources (cognitive ability and human capital) as independent variables, business owners' elaborate and proactive planning as a mediator, and business size and growth as dependent variables. Three studies with a total of 408 African micro and small-scale business owners were conducted in South Africa, Zimbabwe, and Namibia. Structural equation analyses partially supported the hypotheses on the importance of psychological planning by the business owners. Elaborate and proactive planning was substantially related to business size and to an external evaluation of business success and was a (partial) mediator for the relationship between cognitive resources and business success. The model carries important implications for selection, training, and coaching of business owners.  相似文献

Social focal point theory predicts that, in matching, people search for a shared characteristic that makes one decision option salient whereas, in mismatching, they search for complementary characteristics that make different options salient for each of the coordinating parties. In two studies, participants learned about a partner’s activity preferences and then tried to either match or mismatch choices on a series of pictures that were remotely associated with one of these preferences. Being the same on a relevant preference facilitated matching whereas being different facilitated mismatching. In the second study, participants also used overall perceived similarity to supplement specific trait information. Coordination performance also affected interpersonal impressions: successful matching increased interpersonal attraction whereas successful mismatching did not. These downstream effects were obtained even when participants had considerable prior social information about their partners. Tacit coordination is compared with mimicry and synchrony, and the implications for coordinated team performance are discussed.  相似文献

A culturally diverse sample of formerly homeless youth (ages 6–12) and their families (n?=?223) participated in a cluster randomized controlled trial of the Early Risers conduct problems prevention program in a supportive housing setting. Parents provided 4 annual behaviorally-based ratings of executive functioning (EF) and conduct problems, including at baseline, over 2 years of intervention programming, and at a 1-year follow-up assessment. Using intent-to-treat analyses, a multilevel latent growth model revealed that the intervention group demonstrated reduced growth in conduct problems over the 4 assessment points. In order to examine mediation, a multilevel parallel process latent growth model was used to simultaneously model growth in EF and growth in conduct problems along with intervention status as a covariate. A significant mediational process emerged, with participation in the intervention promoting growth in EF, which predicted negative growth in conduct problems. The model was consistent with changes in EF fully mediating intervention-related changes in youth conduct problems over the course of the study. These findings highlight the critical role that EF plays in behavioral change and lends further support to its importance as a target in preventive interventions with populations at risk for conduct problems.  相似文献

The categorization and identification of previously ignored visual or auditory stimuli is typically slowed down—a phenomenon that has been called the negative priming effect and can be explained by the episodic retrieval of response-inadequate prime information and/or an inhibitory model. A similar after-effect has been found in visuospatial tasks: participants are slowed down in localizing a visual stimulus that appears at a previously ignored location. In the auditory modality, however, such an after-effect of ignoring a sound at a specific location has never been reported. Instead, participants are impaired in their localization performance when the sound at the previously ignored location changes identity, a finding which is compatible with the so-called feature-mismatch hypothesis. Here, we describe the properties of auditory spatial in contrast to visuospatial negative priming and report two experiments that specify the nature of this auditory after-effect. Experiment 1 shows that the detection of identity-location mismatches is a genuinely auditory phenomenon that can be replicated even when the sound sources are invisible. Experiment 2 reveals that the detection of sound-identity mismatches in the probe depends on the processing demands in the prime. This finding implies that the localization of irrelevant sound sources is not the inevitable consequence of processing the auditory prime scenario but depends on the difficulty of the target search process among distractor sounds.  相似文献

Background

In the last decades much has been found out about the stigmatization of persons with mental illnesses. Recently, a potential stigmatization of psychologists, psychiatrists and psychotherapy has been debated.

Aim

The question should be answered whether there is any scientific evidence for stigmatization of psychologists, psychiatrists and psychotherapy by using the conceptualization of stigma as brought forward by Link and Phelan (Ann Rev Sociol 2001; 27:363–385).

Material and methods

For the systematic literature search in 2013 a databank search was carried out in Web of Science using the search terms stigma or discrimination or stereotypes or prejudice AND psychiatrist or psychotherapist or psychotherapy or mental health professional. A total of 2013 publications were identified which were systematically arranged according to the title and abstract with respect to the relevance for the question whether psychotherapy or associated professional groups are stigmatized. Only four of the articles were considered to be relevant. After advice from experts six further relevant articles could be found which did not appear in the databank search.

Results

The review found evidence for both positive and negative stereotypes but not for other components of the stigmatization process.

Conclusion

At present there is no evidence for a stigma related to psychotherapy or to the professions of psychotherapists and psychiatrists.  相似文献

The connections between parents' socialization practices and beliefs about emotions, and children's emotional development have been well studied; however, teachers' impacts on children's social–emotional learning (SEL) remain widely understudied. In the present study, private preschool and Head Start teachers (N = 32) were observed using the Classroom Assessment Scoring System. Comparison groups were created based on their observed emotional support and then compared on their qualitative responses in focus group discussions on beliefs about emotions and SEL strategies. Teachers acknowledged the importance of preparing children emotionally (as well as academically) for kindergarten, but substantial differences emerged between the highly emotionally supportive and moderately emotionally supportive teachers in three areas: (1) teachers' beliefs about emotions and the value of SEL; (2) teachers' socialization behaviours and SEL strategies; and (3) teachers' perceptions of their roles as emotion socializers. Understanding such differences can facilitate the development of intervention programs and in‐service training to help teachers better meet students' SEL needs.

Working memory training has been the focus of intense research interest. Despite accumulating behavioral work, knowledge about the neural mechanisms underlying training effects is scarce. Here, we show that 7 days of training on an n-back task led to substantial performance improvements in the trained task; furthermore, the experimental group showed cross-modal transfer, as compared with an active control group. In addition, there were two neural effects that emerged as a function of training: first, increased perfusion during task performance in selected regions, reflecting a neural response to cope with high task demand; second, increased blood flow at rest in regions where training effects were apparent. We also found that perfusion at rest was correlated with task proficiency, probably reflecting an improved neural readiness to perform. Our findings are discussed within the context of the available neuroimaging literature on n-back training.  相似文献

As part of the longitudinal study ?Chances and risks during the life course“, the emergence of deviant and delinquent behavior is studied. The data basis of the present study consists of self-reports of male ninth grade pupils from Dortmund and Nuremberg schools (n?=?726). Particularly, data applying to perpetration of an offence in the past year were analyzed, including dark-figures data for violent offences. The indices for violent crime were related to several psychosocial characteristics (e.g. violence-approving attitudes, self-centered personality traits and corporal punishment by parents), considering type of school and migration background. From a developmental psychopathology perspective, these psychosocial characteristics can contribute to juvenile delinquency and violence. Overall, the empirical findings suggest that juveniles with migration backgrounds show significantly more violence and peer delinquency than juveniles without migration backgrounds. Furthermore, there seems to be empirical evidence that there are significant differences between violent offenders and non-violent offenders or young people with migration backgrounds and young people without migration backgrounds, respectively, with regard to various psychosocial characteristics. Additional results refer to school type specific analyses. Limitations of the present study and implications of the findings for future research on juvenile violence are discussed focusing on violence prevention and interventional approaches.  相似文献
