Previous studies of tactile spatial perception focussed either on a single point of stimulation, on local patterns within a single skin region such as the fingertip, on tactile motion, or on active touch. It remains unclear whether we should speak of a tactile field, analogous to the visual field, and supporting spatial relations between stimulus locations. Here we investigate this question by studying perception of large-scale tactile spatial patterns on the hand, arm and back. Experiment 1 investigated the relation between perception of tactile patterns and the identification of subsets of those patterns. The results suggest that perception of tactile spatial patterns is based on representing the spatial relations between locations of individual stimuli. Experiment 2 investigated the spatial and temporal organising principles underlying these relations. Experiment 3 showed that tactile pattern perception makes reference to structural representations of the body, such as body parts separated by joints. Experiment 4 found that precision of pattern perception is poorer for tactile patterns that extend across the midline, compared to unilateral patterns. Overall, the results suggest that the human sense of touch involves a tactile field, analogous to the visual field. The tactile field supports computation of spatial relations between individual stimulus locations, and thus underlies tactile pattern perception.  相似文献

This study examined the effects of cultural-values conflict and parental expectations on the career decision-making difficulties of university students in three cities in China (Beijing, Wuhan, and Hong Kong, N = 1342). The Multidimensional Scales of Individual Traditionality and Modernity (Yang, Yu, & Ye, 1989) were used as a measure of cultural-values conflict and cultural orientation. The Living-Up-to Parental Expectation Inventory (Wang & Heppner, 2002) was used to measure parental expectations. The Career Decision-Making Difficulties Questionnaire (Gati & Saka, 2001) was used as a dependent measure. It was found that levels of cultural-value conflict were associated with higher levels of career decision-making difficulties for students in the Chinese Mainland cities but not for students in Hong Kong. Perceived parental expectations and perceived self-performance in the expected areas were found to be predictive of career decision-making difficulties. Cultural-value orientation, especially endorsement of Chinese traditional values, was found to moderate the relationship between parental expectation and career decision-making difficulties. Theoretical, research and practical implications of findings were discussed.  相似文献

Despite frequent informal or anecdotal acknowledgement of the usefulness of neuropsychological services within various settings, including mental health settings, few studies have formally investigated the satisfaction, perceived utility, or outcomes associated with such a service. This survey‐based study evaluated referring clinicians’ (n = 35) perceptions of the usefulness and outcomes associated with the provision of clinical neuropsychological assessment and feedback within an adolescent and young adult public mental health service in Melbourne, Australia. The results suggest that referrers perceive the neuropsychological service, including formal neuropsychological assessment report and verbal and written feedbacks, as a highly useful adjunct to their clinical practice. In addition, referrers frequently reported clinically meaningful outcomes in association with the neuropsychological service, including diagnostic changes or additions (11% of clients referred), changes to approaches in treatment (52% of clients referred), and increased or appropriate access to services, education, or work (33% of clients referred). Referrers also reported that almost 60% of neuropsychological assessment reports were forwarded to other services or clinicians involved in the client's care. The findings suggest that mental health settings are likely to benefit from routine inclusion of specialist neuropsychology services. However, future research should also examine client and family perceptions regarding the satisfaction and usefulness of neuropsychological services.  相似文献

Diminished positive experiences and events might be part of the phenomenology of social anxiety; however, much of this research is cross-sectional by design, limiting our understanding of the everyday lives of socially anxious people. Sexuality is a primary source of positive experiences. We theorized that people with elevated social anxiety would have relatively less satisfying sexual experiences compared to those who were not anxious. For 21 days, 150 college students described their daily sexual episodes. Social anxiety was negatively related to the pleasure and feelings of connectedness experienced when sexually intimate. The relationship between social anxiety and the amount of sexual contact differed between men and women—it was negative for women and negligible for men. Being in a close, intimate relationship enhanced the feelings of connectedness during sexual episodes for only individuals low in social anxiety. Depressive symptoms were negatively related to the amount of sexual contact, and the pleasure and feelings of connectedness experienced when sexually intimate. Controlling for depressive symptoms did not meaningfully change the social anxiety effects on daily sexuality. Our findings suggest that fulfilling sexual activity is often compromised by social anxiety.  相似文献

Long hours of paid employment during high school have been linked to a variety of problem behaviors, but questions remain about whether and to what extent work intensity makes any causal contribution. This study addresses those questions by focusing on how 12th-grade work intensity is associated with substance use and educational attainment in the years following high school. It uses 2 nationally representative longitudinal data sets from the Monitoring the Future project, spanning a total of 3 decades. One data set tracks 8th graders for 8 years (modal ages 14-22) and provides extensive controls for possible prior causes; the second, larger data set tracks 12th graders for up to 12 years (to modal ages 29-30) and permits assessment of possible short-term and longer term consequences. Findings based on propensity score matching and multivariate regression analyses are highly consistent across the 2 sets of data. All findings show that more fundamental prior problems, including low academic performance and aspirations, make substantial contributions to substance use and long-term academic attainment (selection effects), but the findings also suggest that high work intensity during high school has long-term costs in terms of college completion and perhaps cigarette use.  相似文献

Prior research has demonstrated deficits in defensive reactivity (indexed by potentiation of the startle blink reflex) in psychopathic individuals. However, the basis of this association remains unclear, as diagnostic criteria for psychopathy encompass two distinct phenotypic components that may reflect differing neurobiological mechanisms-an affective-interpersonal component and an antisocial deviance component. Likewise, the role of defensive response deficits in antisocial personality disorder (APD), a related but distinct syndrome, remains to be clarified. In the current study, the authors examined affective priming deficits in relation to factors of psychopathy and symptoms of APD using startle reflex methods in 108 adult male prisoners. Deficits in blink reflex potentiation during aversive picture viewing were found in relation to the affective-interpersonal (Factor 1) component of psychopathy, and to a lesser extent in relation to the antisocial deviance (Factor 2) component of psychopathy and symptoms of APD-but only as a function of their overlap with affective-interpersonal features of psychopathy. These findings provide clear evidence that deficits in defensive reactivity are linked specifically to the affective-interpersonal features of psychopathy and not to the antisocial deviance features represented most strongly in APD.  相似文献

The CuPS (Culture × Person × Situation) approach attempts to jointly consider culture and individual differences, without treating either as noise and without reducing one to the other. Culture is important because it helps define psychological situations and create meaningful clusters of behavior according to particular logics. Individual differences are important because individuals vary in the extent to which they endorse or reject a culture's ideals. Further, because different cultures are organized by different logics, individual differences mean something different in each. Central to these studies are concepts of honor-related violence and individual worth as being inalienable versus socially conferred. We illustrate our argument with 2 experiments involving participants from honor, face, and dignity cultures. The studies showed that the same "type" of person who was most helpful, honest, and likely to behave with integrity in one culture was the "type" of person least likely to do so in another culture. We discuss how CuPS can provide a rudimentary but integrated approach to understanding both within- and between-culture variation.  相似文献

This study systematically replicated and extended previous research on response interruption and redirection (RIRD) by assessing instructed responses of a different topography than the target behavior, percentage of session spent in treatment, generalization of behavior reduction, and social validity of the intervention. Results showed that RIRD produced substantial decreases in vocal stereotypy. Limitations of this study were that behavior reduction did not generalize to novel settings or with novel instructors and that appropriate vocalizations did not improve.  相似文献
