Ostracized individuals demonstrate an increased need for belonging. To satisfy this need, they search for signals of inclusion, one of which may be another person’s gaze directed at oneself. We tested if ostracized, compared to included, individuals judge a greater degree of averted gaze as still being direct. This range of gaze angles still viewed as direct has been dubbed “the cone of (direct) gaze”. In the current research, ostracized and included participants viewed friendly-looking face stimuli with direct or slightly averted gaze (0°, 2°, 4°, 6°, and 8° to the left and to the right) and judged whether stimulus persons were looking at them or not. Ostracized individuals demonstrated a wider gaze cone than included individuals. 相似文献

People with higher IQ scores also tend to perform better on elementary cognitive-perceptual tasks, such as deciding quickly whether an arrow points to the left or the right Jensen (2006). The worst performance rule (WPR) finesses this relation by stating that the association between IQ and elementary-task performance is most pronounced when this performance is summarized by people’s slowest responses. Previous research has shown that the WPR can be accounted for in the Ratcliff diffusion model by assuming that the same ability parameter—drift rate—mediates performance in both elementary tasks and higher-level cognitive tasks. Here we aim to test four qualitative predictions concerning the WPR and its diffusion model explanation in terms of drift rate. In the first stage, the diffusion model was fit to data from 916 participants completing a perceptual two-choice task; crucially, the fitting happened after randomly shuffling the key variable, i.e., each participant’s score on a working memory capacity test. In the second stage, after all modeling decisions were made, the key variable was unshuffled and the adequacy of the predictions was evaluated by means of confirmatory Bayesian hypothesis tests. By temporarily withholding the mapping of the key predictor, we retain flexibility for proper modeling of the data (e.g., outlier exclusion) while preventing biases from unduly influencing the results. Our results provide evidence against the WPR and suggest that it may be less robust and less ubiquitous than is commonly believed. 相似文献

Background
Psychological distress among students is receiving growing attention in the scientific community as well as in the general public. There are counseling services available in student societies and universities which address psychological distress among students but scientific research in this area is rudimentary and poorly represented.Problem in question
In order to present the prevalence, extent and type of psychological disorders in students and the alterations over time, an investigation was carried out to show which psychological complaints and disorders were present in students who consulted a psychotherapeutic counseling center. These data were compared with the psychological complaints of a student field study population. Furthermore, alterations in the psychological complaints and disorders of students over periods of 10 and 15 years will be presented.Methods
The prevalence and change over time of psychological syndromes in students were identified by a comparison between an unselected sample of counseling center clients and several student field samples from the previous 15 years. The type of distress and severity of symptoms were measured with a Symptom Checklist (SCL-90-R), the Psychosocial Complaints List (PSB), the Satisfaction With Life And Studies Scale (LSZ), the diagnostic assessment according to International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10), the Complaints Severity Score (BSS) and Global Assessment of Functioning (GAF).Results
Previous results of investigations which showed that 20–25% of students suffer from psychological disorders could be confirmed in this study. However, 60–65% of the clients of a counseling center suffered from clinically relevant psychological disorders, which is significantly higher. The most common disorders were depressive moods, lack of self-confidence and exam anxiety, which can mostly be diagnostically assigned to adjustment, depression and anxiety disorders. The comparison with previous studies showed that the types and severity of psychological distress among students have remained stable over the last 15 years, with the exception of test anxiety which increased by 51% from 1993 to 2008. With respect to alcohol abuse, considerably less impairments were found than had been assumed based on the earlier investigations.Conclusions
Psychological complaints and disorders are frequently found among students and they cause individual suffering as well as economic expenses. Noticeable was the obvious increase in clinically relevant exam anxiety. Psychological-psychotherapeutic counseling centers make an important contribution to screening, clinical assessment, primary health care and prevention of severe mental disorders among students and have shown a continuously increasing number of cases in recent years. Further studies especially in a process-outcome design of the mostly eclectic counseling centers are needed and possibilities will be presented. 相似文献304.
ABSTRACT— The stigma of mental illness imposes substantial costs on both the individuals who experience mental illness and society at large. Understanding the psychological underpinnings of this stigma is therefore a matter of practical and theoretical significance. In a national, Web-based survey experiment, we investigated the role played by gender in moderating mental-illness stigma. Respondents read a case summary in which the gender of the person was orthogonally manipulated along with the type of disorder; the cases reflected either a male-typical disorder or a female-typical disorder. Results indicated that when cases were gender typical, respondents felt more negative affect, less sympathy, and less inclination to help, compared to when cases were gender atypical. This pattern can be explained by the fact that gender-typical cases were significantly less likely to be seen as genuine mental disturbances. 相似文献

The research on commons dilemmas is characterized by innumerable published findings, each standing relatively isolated from the other. To date there is little integration of the findings under a unified concept. The present contribution aims to integrate already existing findings in a general dynamic model of cooperative behavior in resource crises by means of computer simulation. The model postulates that people base their decisions regarding resource use on both ecological and social information. Whether or not ecological or social information will dominate, however, depends on people's social values, attributions, and their perceptions of the state of the resource. The advantage of the simulation method used is that successful integration of the findings can be shown explicitly, as the simulation then replicates the experimental data. With the model presented here, it is also possible to let variables work together whose interaction has not yet been investigated in real experiments. For instance, the simulation model allows us to hypothesize that people, in dependency upon their resource uncertainty and in dependency upon their attributions, utilize a resource completely differently if the resource is in an optimal or sub‐optimal condition.

The ability to recognise kin has been demonstrated in several animal species. However, the mechanisms of kin recognition often remain unknown. The most frequently discussed sensory modalities to recognise kin are visual, olfactory and acoustical cues. Three-spined sticklebacks (Gasterosteus aculeatus) are able to differentiate between kin and non-kin when presented visual and olfactory cues combined. To elucidate, which cues they use to recognise kin female sticklebacks were given the choice between two identical computer animations of courting stickleback males. Next to one animation, water conditioned by a brother was added, while near the other, water from an unrelated male was added. In half of the experiments, the brother was familiar while in the other half he was unfamiliar to the female. Both scenarios were carried out with both outbred and inbred fish. The results showed that the females adjusted their choice behaviour according to relatedness. Furthermore, they were able to recognise both familiar as well as unfamiliar brothers. Inbreeding did not affect this ability. Hence, three-spined sticklebacks are able to recognise their relatives using olfactory cues alone. The cognitive mechanisms underlying this ability were independent from familiarity and not impaired by inbreeding. 相似文献
