Availability of brief, self-report measures to be used as screening instruments is crucial to detect correctly youth with social anxiety disorder and therefore, reach those otherwise under-detected and under-treated. A previous study revealed that the Social Phobia Inventory (SPIN) was potentially an appropriate measure for screening social anxiety among US adolescents. However, there is a lack of information concerning its properties as a screening test in other cultures and languages. This is the main objective of this study, although further validity of the scale is provided as well. The sample consisted of 192 adolescents (a sample composed of 114 subjects with a principal diagnosis of social anxiety disorder; and a group consisting of 78 subjects with no diagnosis of social phobia). Results suggest that the Social Phobia Inventory has demonstrated good psychometric properties and indeed may be used as a screening tool in Spanish-speaking adolescents. 相似文献

The Clock Drawing Test (CDT) is a widely used instrument in the neuropsychological assessment of Alzheimer's disease (AD). As CDT performance necessitates several cognitive functions (e.g., visuospatial and constructional abilities, executive functioning), an interaction of multiple brain regions is likely. Fifty-one subjects with mild cognitive impairment, 23 with AD and 15 healthy controls underwent high-resolution magnetic resonance imaging. Optimized voxel-based morphometry (VBM) was performed to investigate the putative association between CDT performance and gray matter (GM) density throughout the entire brain. In the first step of analysis (p<.001, uncorrected), VBM revealed a reduced GM density in numerous cortical (temporal lobe, frontal lobe, parietal lobe, cerebellum) and subcortical (thalamus, basal ganglia) brain regions to be associated with poorer CDT performance. When corrected for multiple comparisons (p<.01), the associations remained significant predominantly in the left temporal and--less pronounced--the right temporal lobe. VBM demonstrated CDT performance to depend on the integrity of widely distributed cortical and subcortical areas in both brain hemispheres with accentuation in the left-sided temporal lobe region. 相似文献

A reciprocal and ongoing interaction about theory and clinical technique developed between Freud and Ferenczi in the years from 1908 to 1933. During the course of this ongoing dialogue, the concept of psychic trauma gradually transformed. Ferenczi continued to elaborate on this issue, and concluded with his work on the interaction of trauma and fantasy. Ferenczi initially refuted Freud's early trauma theses and finally conceptualized a metapsychological reformulation of trauma, an inverse development to Freud's formulations. Ferenczi highlighted two essential concepts in the theory and technique of trauma: the processes of identification and the splitting of the ego, while he stressed the enormous role of disavowal in the dynamics of trauma. The author hopes to demonstrate how Ferenczi's contributions added to developments of the concepts of disavowal and temporality, to the recovery of traumatic memory and the modification of the classical concept of interpretations. 相似文献

Parametric induction of animacy experience 总被引:2,自引:1,他引:1
Graphical displays of simple moving geometrical figures have been repeatedly used to study the attribution of animacy in human observers. Yet little is known about the relevant movement characteristics responsible for this experience. The present study introduces a novel parametric research paradigm, which allows for the experimental control of specific motion parameters and a predictable influence on the attribution of animacy. Two experiments were conducted using 3D computer animations of one or two objects systematically introducing variations in the following aspects of motion: directionality, discontinuity and responsiveness. Both experiments further varied temporal kinematics. Results showed that animacy experience increased with the time a moving object paused in the vicinity of a second object and with increasing complexity of interaction between the objects (approach and responsiveness). The experience of animacy could be successfully modulated in a parametric fashion by the systematic variation of comparably simple differential movement characteristics. 相似文献

Mental workload and visual impairment: differences between pupil, blink, and subjective rating 总被引:1,自引:0,他引:1
This research has two aims: (a) To study the concurrent validity of three measures of mental workload, NASA TLX rating scale, pupil dilation and blink rate, testing the hypothesis that they will provide convergent results using a single-task, and dissociative results for dual-task; and (b) To analyse their capability to predict visual search impairment. These three measures were analyzed in the same cognitive tasks in single-task and dual-task (cognitive task and visual search) conditions in a within-subjects experiment with twenty-nine participants. Mental workload measures showed concurrent validity under single-task condition, but a complex pattern of results arose in the dual-task condition: it is suggested that NASA TLX would be a subjective addition of the rating of each task; pupil dilation would measure the average arousal underlying the cognitive tasks; and the blink rate would produce opposite effects: whereas mental workload of cognitive tasks would increase blink rate, visual demand would inhibit it. All three measures were good predictors of visual impairment. The soundness of these measures is discussed with regard to the applied field of driving and other activities. 相似文献

Vigilance or scanning involves interruptions in foraging behavior when individuals lift their heads and conduct visual monitoring of the environment. Theoretical considerations assume that foraging with the "head down", and scanning ("head up") are mutually exclusive activities, such that foraging precludes vigilance. We tested this generalization in a socially foraging, small mammal model, the diurnal Chilean degu (Octodon degus). We studied spontaneous bouts of scanning of captive degus when foraging in pairs of female sibs and non-sibs. We examined the extent to which foraging (head down postures) and scanning (head up postures) were mutually exclusive in subjects exposed to none, partial, and complete lateral visual obstruction of their partners. In addition, we monitored the orientation of their bodies to examine the target of attention while foraging and scanning. Lastly, we examined the temporal occurrence of scanning events to assess the extent of scanning coordination, and whether this coordination is kin-biased. Visual obstruction had a significant influence on degu vigilance. Focal degus increased their quadrupedal and semi-erect scanning when foraging under a partially obstructed view of their partners. Degus oriented their bodies toward partners when foraging and scanning. Despite this, degus did not coordinate scanning bouts; instead, they scanned independently from one another. Relatedness among cage mates did not influence any aspect of degu behavior. Contrary to theoretical expectations, these results indicate that foraging and vigilance are not mutually exclusive, and that kinship per se does not influence scanning behavior and coordination. 相似文献

Three studies explored the hypothesis that implicit measures of prejudice can tap negative, yet egalitarian associations. In Study 1, automatically associating African Americans with oppression predicted greater automatic prejudice. In Studies 2 and 3, classically conditioning associations between the novel group Noffians and words like oppressed, maltreated, and victimized led to greater automatic prejudice against Noffians. Results suggest that White Americans’ negative automatic associations with African Americans may partly result from associating members of low status groups with unfair circumstances. Because automatic associations predict prejudiced behaviors, the burden of proof is on those wishing to argue that egalitarian negative associations complicate the assessment of automatic attitudes rather than contribute to prejudiced responses. Discussion focuses on the implications of egalitarian negative associations for the theory and measurement of automatic prejudice. 相似文献

The relationships between self-report and observer-rating versions of personality questionnaires within families in the Spanish cultural context were studied. In the first sample, 336 couples rated the personality of one of their children. The children also assessed their own personality. Goldberg's adjectives were administered. In the second sample, 120 university students rated the personality of their parents. Both parents also assessed their own personality. In this case, Goldberg's adjectives and the NEO-PI-R were administered. Results replicate the level of agreement found in other cultural contexts. Correlations were around .40, and the effect size of the mean differences was not large. Children were more accurate than parents, larger agreement coefficients were found for the NEO-PI-R than for Goldberg's adjectives in Sample 2, especially for the Openness factor, and no substantial role for the sex variable was found in either sample. Implications and limitations of the present study are discussed. 相似文献

The presence of violent behaviors of a psychological and physical nature in dating relations was analyzed in a sample of Spanish university students between 18 and 27 years of age. The results indicate a high prevalence of both kinds of aggression in interpersonal relationships, revealing important typology differences between the sexes. Violent psychological behaviors (characterized by the presence of verbal aggression and coercive and jealous behaviors) and physical aggression were significantly higher in women, though the consequences of physical aggression were worse for the women's health. The implications of the results and their possible relation with more severe violent acts in more stable, emotional relationships are discussed. 相似文献

The effect of unimanual practice of the non-preferred hand on manual asymmetry and manual preference for sequential finger movements was evaluated in right-handers before, immediately after, and 30 days following practice. The results demonstrate that unimanual practice induced a persistent shift of manual preference for the experimental task in most participants, but no significant correlation between manual asymmetry and manual preference was detected. These findings are explained by proposing that manual preference is influenced by a task-specific confidence developed from the recent history of differential use of the limbs, in interaction with a generalized confidence on a single hand for performance of motor skills. 相似文献
