Spatial navigation within a real 3-D maze was investigated to study space perception on the sole basis of tactile information transmitted by means of a 'tactile vision substitution system' (TVSS) allowing the conversion of optical images-collected by a micro camera-into 'tactile images' via a matrix in contact with the skin. The development of such a device is based on concepts of cerebral and functional plasticity, enabling subjective reproduction of visual images from tactile data processing. Blindfolded sighted subjects had to remotely control the movements of a robot on which the TVSS camera was mounted. Once familiarised with the cues in the maze, the subjects were given two exploration sessions. Performance was analysed according to an objective point of view (exploration time, discrimination capacity), as well as a subjective one (speech). The task was successfully carried out from the very first session. As the subjects took a different path during each navigation, a gradual improvement in performance (discrimination and exploration time) was noted, generating a phenomenon of learning. Moreover, subjective analysis revealed an evolution of the spatialisation process towards distal attribution. Finally, some emotional expressions seemed to reflect the genesis of 'qualia' (emotional qualities of stimulation). 相似文献

Predictors of posttraumatic stress disorder and symptoms in adults: a meta-analysis 总被引:28,自引:0,他引:28
A review of 2,647 studies of posttraumatic stress disorder (PTSD) yielded 476 potential candidates for a meta-analysis of predictors of PTSD or of its symptoms. From these, 68 studies met criteria for inclusion in a meta-analysis of 7 predictors: (a) prior trauma, (b) prior psychological adjustment, (c) family history of psychopathology, (d) perceived life threat during the trauma, (e) posttrauma social support, (f) peritraumatic emotional responses, and (g) peritraumatic dissociation. All yielded significant effect sizes, with family history, prior trauma, and prior adjustment the smallest (weighted r = .17) and peritraumatic dissociation the largest (weighted r = .35). The results suggest that peritraumatic psychological processes, not prior characteristics, are the strongest predictors of PTSD. 相似文献

Brown's factors [J. Speech Disorders 10 (1945) 181] predict the likely loci of disfluency in English-speaking adults who stutter. A word is more likely to be stuttered for these speakers if it is a content word, starts with a consonant, is positioned at the beginning of a sentence, and if it is a long word. These same factors were examined in native German-speaking children and adults who stutter. Speech data of 15 German adults and 17 children were coded according to Brown's factors. For the adult group, it was predicted that words starting with consonants would not lead to as much of an increase in disfluencies compared with English samples, because of cross-linguistic differences in syllable onset properties. It was predicted that stuttering would be more likely in later sentence positions in German because in German the verb is usually near the end of a sentence. There were no obvious reasons to expect differences on the two remaining factors, content words and word length. With children, it was hypothesised that Brown's factors that specify level of linguistic difficulty would not be such a good predictor of stuttering rate. Specifically, it was predicted that the difference in stuttering rate between function and content words would be lower in children. For the adults both word type (content/function) and word length increased stuttering rate significantly, whereas changes in stuttering rate for the other two factors were non-significant. It was also found that when word difficulty (based on a combined measure of all factors) increased, stuttering rate rose. With children, only the word-length factor was significant, and stuttering rate was not governed to the same extent by overall word difficulty. Conclusions are drawn as to the effect of linguistic and motor influences on stuttering. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to describe: (1) how linguistic factors affect stuttering rates in German; (2) the different patterns of adults and children who stutter and how language might influence this pattern; and (3) how to interpret these findings in light of a current theory of fluency failure. 相似文献

This study addressed how various outcomes to a leader might influence not only how that leader is perceived but also the degree of influence that leader might subsequently obtain. On the basis of recent charismatic leadership theories, it was expected that leaders who appeared willing to endure hardship for the expression of their beliefs would be perceived differently than leaders who appeared to benefit in some way. The relationship between outcomes and subsequent leader influence was confirmed. Sacrificing resulted in greater influence, whereas benefiting reduced it. This relationship was mediated by attributions made about leader motives. The relationship between outcomes and influence was also mediated by perceptions of charisma. 相似文献

Research has demonstrated an association between perfectionism and depressive and anxious symptoms in children. We examined whether a school-based program targeting anxious and depressive symptoms would reduce perfectionism, and whether perfectionism would interfere with intervention outcomes. The participants were 78 school-age children identified as at-risk for anxiety and/or depression. At-risk children took part in a randomized controlled trial of a school-based intervention program. Levels of perfectionism, depression, and anxiety were assessed at pre-treatment (Time 1) and again at post-treatment (Time 2) after participating in either a cognitive behavioral group or a structured activity group. Participation in either group was associated with significant reductions in overall levels of self-oriented perfectionism, anxious symptoms, and depressive symptoms. Supplementary analyses indicated that pre-treatment self-oriented perfectionism influenced post-treatment depression scores, suggesting that perfectionism interferes with treatment outcome. Perfectionism in children appeared amenable to group-based intervention, and identifying perfectionism may be important for treating children with depressive symptoms. 相似文献

This study examined links between two distinct facets of empathy-empathic accuracy and perceived empathic effort-and one's own and one's partner's relationship satisfaction. Using a video recall procedure, participants (n = 156 couples in committed relationships) reported on their own emotions and their perceptions of partners' emotions and partners' empathic intentions during moments of high affect in laboratory-based discussions of upsetting events. Partners' data were correlated as a measure of how accurately they were able to read what the other was feeling and to what degree they felt the other was trying to be empathic at those moments. The perception of empathic effort by one's partner was more strongly linked with both men's and women's relationship satisfaction than empathic accuracy. Men's relationship satisfaction was related to the ability to read their partners' positive emotions accurately, whereas women's relationship satisfaction was related to their partners' ability to read women's negative emotions accurately. Women's ability to read their husbands' negative emotions was positively linked to both men's and women's relationship satisfaction. Findings suggest that the perception of a partner's empathic effort-as distinct from empathic accuracy-is uniquely informative in understanding how partners may derive relationship satisfaction from empathic processes. When working with couples in treatment, heightening partners' perceptions of each other's empathic effort, and helping partners learn to demonstrate effort, may represent particularly powerful opportunities for improving satisfaction in relationships. 相似文献

Counseling studies have shown that increasing experience is not always associated with better judgments. However, in such studies performance is assessed against external criteria, which may lack validity. The authors applied the Cochran–Weiss–Shanteau (CWS) index, which assesses the ability to consistently discriminate. Results showed that novice counselors performed almost on the same level as very experienced counselors. The authors thus replicated earlier findings with a novel approach: applying an internal coherence criterion. 相似文献
