Long‐term deprivation of normal visual inputs can cause perceptual impairments at various levels of visual function, from basic visual acuity deficits, through mid‐level deficits such as contour integration and motion coherence, to high‐level face and object agnosia. Yet it is unclear whether training during adulthood, at a post‐developmental stage of the adult visual system, can overcome such developmental impairments. Here, we visually trained LG, a developmental object and face agnosic individual. Prior to training, at the age of 20, LG's basic and mid‐level visual functions such as visual acuity, crowding effects, and contour integration were underdeveloped relative to normal adult vision, corresponding to or poorer than those of 5–6 year olds (Gilaie‐Dotan, Perry, Bonneh, Malach & Bentin, 2009). Intensive visual training, based on lateral interactions, was applied for a period of 9 months. LG's directly trained but also untrained visual functions such as visual acuity, crowding, binocular stereopsis and also mid‐level contour integration improved significantly and reached near‐age‐level performance, with long‐term (over 4 years) persistence. Moreover, mid‐level functions that were tested post‐training were found to be normal in LG. Some possible subtle improvement was observed in LG's higher‐order visual functions such as object recognition and part integration, while LG's face perception skills have not improved thus far. These results suggest that corrective training at a post‐developmental stage, even in the adult visual system, can prove effective, and its enduring effects are the basis for a revival of a developmental cascade that can lead to reduced perceptual impairments.  相似文献

We discuss prior publication and redundancy in contemporary science in the context of changing perceptions of originality in the communication of research results. These perceptions have been changing in the publication realm, particularly in the last 15 years. Presenting a brief overview of the literature, we address some of the conflicts that are likely to arise between authors and editors. We illustrate our approach with conference presentations that are later published as journal articles and focus on a recent retraction of an article that had been previously published as a conference proceedings. Although we do not make definitive pronouncements on the matter—as many concepts are evolving—we do argue that conference papers that contain sufficient details for others to attempt a replication and are indexed in scientific databases such as PubMed, challenge some currently held assumptions of prior publication and originality in the sciences. Our view is that these important issues are in need of further clarification and harmonization within the science publishing community. This need is more evident when we consider current notions of research integrity when it comes to communication to peers. Revisiting long-standing views about what constitutes prior publication and developing a clearer set of guidelines for authors and editors to follow should reduce conflicts in the research environment, which already exerts considerable pressure, especially on newcomers in academia. However, while clearer guidelines are timely, developing them is only part of the challenge. The present times seem to call for deeper changes in the research and publication systems.  相似文献

The belief that happiness is fragile—that it is fleeting and may easily turn into less favourable states—is common across individuals and cultures. However, not much is known about this belief domain and its structure and correlates. In the present study, we use multigroup confirmatory factor analysis and multilevel modelling to investigate the measurement invariance, cross-level isomorphism, predictive validity, and nomological network of the fragility of happiness scale across 15 nations. The results show that this scale has good statistical properties at both individual and cultural levels, and is associated with relevant psycho-social concepts in expected directions. The importance of the results, limitations, and potential directions for future research are discussed.  相似文献

The published norms for the Depression Anxiety and Stress Scale (DASS) give results for clinical populations that largely fall in the severe to very severe categories. As a result, within this population, the ability to compare the comparative contributions of the underlying emotional components is reduced. The present study presents results from a large general psychiatric outpatient population and provides percentile norms with confidence intervals for both the original DASS and the shorter 21‐item form. It is noted that both forms have high validity but that the correlations between scales are higher than those reported in non‐clinical populations. There was little variation between sexes but some variation of results with age with both younger and older cohorts having lower scores except for the Stress scale where there were higher scores in the older group. There is some evidence of a ceiling effect in the Depression and Stress scales. It was noted that nearly a quarter of patient scores fell within the originally defined normal range suggesting that the DASS would not be a particularly sensitive instrument in its previously reported use as a screening instrument for psychiatric illness.  相似文献

We assessed 2 forms of agreement between mothers' and fathers' socially desirable responding in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand and the United States (N = 1110 families). Mothers and fathers in all 9 countries reported socially desirable responding in the upper half of the distribution, and countries varied minimally (but China was higher than the cross‐country grand mean and Sweden lower). Mothers and fathers did not differ in reported levels of socially desirable responding, and mothers' and fathers' socially desirable responding were largely uncorrelated. With one exception, mothers' and fathers' socially desirable responding were similarly correlated with self‐perceptions of parenting, and correlations varied somewhat across countries. These findings are set in a discussion of socially desirable responding, cultural psychology and family systems.  相似文献

A psychotic breakdown in adolescence marks the emergence of a manifest aspect of a more complex process that has its origins in the patient's family pre‐history and in the patient's childhood story. This period of life is characterized by a sensorial explosion and adolescents will react differently according to the different resources they have at their disposal. Adolescents will attempt to create defensive solutions in order to face this decompensation on their own. In particular, polymorphously perverse behaviours can be utilized because of their specific characteristics in order to create a potent defence used to arrest a still more severe regression and at the same time providing the time necessary to safely navigate through a difficult and dangerous developmental phase. These solutions can be transitory or transform themselves into lasting defensive adaptations. These defensive modalities are very complex and articulated and can become fossilized in time, as, for example, in the case of a use of perverse defences against a breakdown. An analyst finding him/herself in these situations will find it difficult to differentiate in the diagnosis between a condition that is due to a perverse functioning used as a defence against decompensation, and a truly perverse structure that is beginning to emerge after puberty.  相似文献

Two studies addressed the role of Black meta‐perception of acculturation attitudes on the relation between minority acculturation attitudes and their social adjustment (school achievement and perceived quality of intergroup relations). Participants in both studies were Black Lusophone adolescents living in Portugal. Study 1 (N = 140) indicated that participants' attitude regarding the host culture was positively correlated with their school achievement and to their evaluation of intergroup relations. It also indicated that participants' meta‐perception of majority attitude add to the explained variance of participants' social adjustment. Study 2 (N = 62) manipulated the perceived majority high/low support of immigrants' learning the host culture. The dependent variable (DV) was perceived quality of intergroup relations. Only in the low support condition were participants' attitudes towards the host culture positively related to perceived quality of Black–White relationships. These results suggest that perceived social context is central to understand the relationship between minority adolescents' acculturation attitudes and key dimensions of their adjustment to host societies.  相似文献

This study examined: (a) whether athletes’ (N = 348) perceived autonomy support (i.e., showing interest in athletes’ input and praising autonomous behavior) differs across contexts (training vs. competition) and sport types (individual vs. team sports), and (b) whether the relationships between autonomy support and effort, enjoyment, and anxiety are affected by context and sport type. Perceived autonomy support did not vary across contexts, but interest in athletes’ input was higher in individual than in team sports. Praise for autonomous behavior was associated positively with effort only when interest in input was high, and this effect was stronger in training than in competition. Finally, praise for autonomous behavior was also positively related to enjoyment in training, while interest in input was positively associated with anxiety in individual sports.  相似文献
