Research has indicated that highly trait-anxious (HTA) individuals exhibit a specific deficit in filtering threat-related distractors from visual–spatial working memory (WM). Prior demonstrations of impaired inhibition control in HTA individuals have mainly focused on tasks that required the inhibition of prepotent response tendencies. Studies on the suppression of emotionally neutral distractors from WM in trait anxiety have also been minimal. In this article, we present a study on the manifestation of general inefficient filtering of neutral distractors during visual–spatial WM maintenance stages in HTA individuals. Female participants performed a visual–spatial WM task while event-related potentials were recorded. They were made to remember the orientations of red rectangles within half of the screen and to ignore all salient green rectangles. As predicted, no significant main effect of group and no interaction between group and condition were found in the N2pc component, suggesting that group differences did not manifest in the initial process of object individuation. During the subsequent WM maintenance phase, HTA individuals were highly inefficient at filtering the irrelevant items from WM, as reflected not only by parallel late contralateral delay activity (CDA; 450 to 900 ms) amplitudes for the distractor condition and the four red items, but also by a smaller filtering efficiency score in the HTA group than in the low-trait-anxiety group. Extending previous studies, our findings verify a general filtering impairment in HTA individuals for task-irrelevant salient distractors during a WM maintenance phase. 相似文献

A robust vision-based staircase identification method is proposed, which comprises 2D staircase detection and 3D staircase localization. The 2D detector pre-screens the input image, and the 3D localization algorithm continues the task of retrieving geometry of the staircase on the reported region in the image. A novel set of principal component analysis-based Haar-like features are introduced, which extends the classical Haar-like features from local to global domain and are extremely efficient at rejecting non-object regions for the early stages of the cascade, and the Viola–Jones rapid object detection framework is improved to adapt the context of staircase detection, modifications have been made on the scanning scheme, multiple detections integrating scheme and the final detection evaluation metrics. The V-disparity concept is applied to detect the planar regions on the staircase surface and locate 3D planes quickly from disparity maps, and then, the 3D position of staircase is localized robustly. Finally, experiments show the performance of the proposed method. 相似文献

The MMPI and MMPI-2 validity scales have long been accepted as standard tools in the assessment of feigned mental disorders
(FMD) based on their extensive empirical validation. Studies are now examining MMPI-2-RF with modified validity scales plus
the new Infrequent Somatic Responses Scale (FS) and the recently-adapted Response Bias Scale (RBS). The current investigation used a known-groups design to examine the
effectiveness of the MMPI-2-RF for differentiating FMD and feigned cognitive impairment (FCI) from patients with genuine disorders
for a large civil forensic sample. Criterion measures included the Structured Interview of Reported Symptoms-2 (SIRS-2) for
the FMD group, and below-chance performances on the Victoria Symptom Validity Test (VSVT) and the Test of Memory Malingering
(TOMM) for the FCI group. For FMD, both F-r and FP-r produced very large effect sizes (ds > 2.00). Moreover, the absence of severe elevations (≥80 T) on F-r proved effective at ruling-out most FMD. For the current
study, a FP-r cut score ≥90 T for FMD produced virtually no false-positives (0.01) and only a moderate level of false-alarms. As predicted
by its detection strategies, most MMPI-2-RF validity scales have limited effectiveness with the FCI group. However, FBS-r
and RBS may be useful in conjunction with other clinical data for ruling out FCI for genuine neuropsychological consults.
An entirely separate concern is whether certain diagnostic groups, such as major depression, will have marked elevations on
MMPI-2-RF scales thereby increasing the likelihood of false-positives. On this point, FP-r performed exceptionally well with unelevated scores (Ms < 55 T) consistently across diagnostic categories. 相似文献

In the aftermath of several school shooting incidents in recent years, students’ perceptions of unsafe schools has been a
major concern for parents, teachers, school officials, school practitioners, and policy-makers. Using Bronfenbrenner’s ecological
systems framework, we examined the micro-, meso-, and exosystem level factors associated with perceptions of unsafe school
environments in a nationally representative sample of 10- to 15-year-old youth in the United States. We found that for the
socio-demographic characteristics, students who were older, male, and poor had increased risks of perceiving higher levels
of unsafe school environments. Within the microsystem of the family, our results indicate that parent-youth discussions of
school activities/events decreased the risk of students perceiving unsafe schools. All of the school environment variables—ease
of making friends, teachers’ involvement, observed weapon carrying, and school rule enforcement—were related in the expected
direction to students’ perceiving their schools as unsafe. At the mesosystem level, findings from our study demonstrate that
variables measuring parental school involvement were unrelated to perceptions of school safety. Finally, at the exosystem
level, we found that students’ perceptions of residing in a safer neighborhood and residence in a non-central city metropolitan
area, compared with a central city, decreased the odds of perceiving school environments as unsafe. School policy and practice
implications are discussed. 相似文献

This study explored a bidirectional impact on the recognition accuracy of various facial expressions deriving from both the observer and sender in a sample of Chinese participants. A facial manipulation task was used to examine the ability of an observer's facial feedback to modulate the recognition of various facial expressions. Furthermore, the effect of a sender's facial expression with an open or closed mouth on recognition accuracy was investigated. The results showed that only recognition accuracy of a sad facial expression was influenced simultaneously by bidirectional sources from a sender and observer. Moreover, the impact of the unidirectional cue of a sender's facial feature (i.e., mouth openness) on happy and neutral faces was found to influence the recognition accuracy of these faces, but not the observer's bodily state. These findings indicate that the bidirectional impact derived from an observer and sender on facial expression recognition accuracy differs for emotional and neutral expressions. 相似文献

The goal of the study was to examine the dimensionality of the Career Decision Self-Efficacy Scale Short Form (CDSES-SF, Betz et al. 1996). Integrating several previous findings from different cultures, we found that the bifactor structure of the CDSES-SF on a Hungarian sample of 649 respondents showed the best model fit. This structure includes a general CDSE factor covering 15 items and the original five specific factors (self-appraisal, occupational information, goal selection, planning, and problem solving) covering three items each. This short form of CDSES shows an acceptable model fit and appropriate reliability in terms of the Cronbach’s alpha and omega values. Regarding career decision self-efficacy, a large proportion of variance was explained by the general factor and to a smaller extent by the specific factors. These results can be considered as a first step in resolving the paradox of the dimensionality of CDSES-SF. 相似文献

Confucianism defined benevolence with “feelings” and “love.” “Feelings” in Confucianism can be mainly divided into three categories:
feelings in general (seven kinds of feelings), love for one’s relatives, and compassion (Four Commencements). The seven kinds
of feeling in which people respond to things can be summarized as “likes and dislikes.” The mind responds to things through
feelings; based on the mind of benevolence and righteousness or feelings of compassion, the expression of feelings can conform
to the principle of the mean and reach the integration of self and others, and of self and external things. The “relations
between the seven kinds of feelings and the Four Commencements,” however, was not developed into a theoretical idea in Confucianism.
After Confucius, the relationship between the universality of natural sympathies and the gradation of love for relatives gradually
became an important subject in Confucian ideas of benevolence and love. By “refuting Yang Zhu and Mozi,” Mencius systematically
expounded on this issue. Love had two ends: self-love and natural sympathies, between which existed the love for relatives.
These two ends were not the two extremes of Yang’s self-interest and Mozi’s universal love. Love for relatives not only implied
a gradation, but also contained universality and transcendence that came from self-love. Love for relatives, natural sympathies
and self-love had a kind of tension and connectivity between two dynamic ends. The Confucian idea of benevolence and love
hence demonstrated differences and interconnectivity. An accurate understanding of such “feelings” and “love” is important
for us to grasp Confucian thoughts on benevolence and its realization. 相似文献
