Objective: A minority of patients show sub-optimal outcomes after weight loss surgery. Research has identified predictors of poor outcomes focusing on the patients’ perspective. No research has explored surgeons’ accounts. Design: Ten Bariatric surgeons were interviewed using a critical incident approach to explore their explanations for sub-optimal outcomes in the context of a real-life case. Data were analysed using thematic analysis. Results: Three main themes were developed: ‘Challenges to success’ highlighting the role of psychosocial issues, poor adherence and patient non-disclosure; ‘Ideal world solutions’ describing who should identify and address psychosocial issues; and ‘Real world compromise’ reflecting the impact of limited resources and weighing up risk between carrying out versus not carrying out surgery. Transcending these themes was the notion of ‘responsibility’ with surgeons balancing the role of the patient, themselves and the health care system. Conclusion: Some surgeons concluded that if they had known before surgery what they know now, they may not have operated. All emphasised that they could only know what was disclosed by the patient, that they were not convinced that not operating would have resulted in better outcomes in the longer term and many felt that they were ‘damned one way or the other’. 相似文献

The present study examined the effect of intergroup distinctiveness and group membership on evaluations of impostors. We predicted that ingroup members would be harsher than outgroup members on an impostor and that perceptions of intergroup distinctiveness would further moderate these evaluations. Specifically, we tested the social identity theory prediction that low intergroup distinctiveness would lead to greater derogation of the impostor (the ‘reactive distinctiveness’ hypothesis) against the self‐categorization hypothesis that high intergroup distinctiveness would instigate more derogation of an impostor (the ‘reflective distinctiveness’ hypothesis). In this study, vegetarians (ingroup members) and meat eaters (outgroup members) were presented with a target claiming to be vegetarian, but caught indulging in a meat dish. We found that ingroup members derogated the impostor more and felt less pleased about discovering the impostor behaviour than did outgroup members. In line with the reflective distinctiveness hypothesis, the heightened derogation displayed by ingroup members only emerged when intergroup distinctiveness was high, an effect that was mediated by ratings of group identification. The discussion focuses on the different responses intergroup distinctiveness may evoke. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

Summer camp programming has a rich history of promoting childhood development. In the care of children with specific childhood psychiatric disorders, the incorporation of targeted cognitive-behavioral principles provides an opportunity to marry targeted evidence-based practices with broader development, in particular social, emotional, and fine- and gross-motor development. This union is synergistic, providing the practitioner with an opportunity to employ cognitive-behavioral practices in an environment that may overcome common barriers to effective interventions outside the scope of the targeted illness. In this paper, the authors describe the preliminary findings concerning a weeklong, 25-hour summer camp program targeting childhood obsessive–compulsive disorder (OCD). Nine children ages 9–12 years participated in this pilot program. Child and parent feedback alike suggested strong treatment acceptability and efficacy in targeting both core symptoms of OCD as well as associated developmental deficits. The camp’s implementation of exposure and response prevention enables an opportunity to report on the capability of employing these strategies in a summer camp setting. In conjunction with an evidence-based treatment program for childhood OCD, a summer camp program specifically targeted for children with OCD presents a valuable tool for improving child welfare and reducing functional impairments. 相似文献

Three methods of synthesizing correlations for meta-analytic structural equation modeling (SEM) under different degrees and mechanisms of missingness were compared for the estimation of correlation and SEM parameters and goodness-of-fit indices by using Monte Carlo simulation techniques. A revised generalized least squares (GLS) method for synthesizing correlations, weighted-covariance GLS (W-COV GLS), was compared with univariate weighting with untransformed correlations (univariate r) and univariate weighting with Fisher's z-transformed correlations (univariate z). These 3 methods were crossed with listwise and pairwise deletion. Univariate z and W-COV GLS performed similarly, with W-COV GLS providing slightly better estimation of parameters and more correct model rejection rates. Missing not at random data produced high levels of relative bias in correlation and model parameter estimates and higher incorrect SEM model rejection rates. Pairwise deletion resulted in inflated standard errors for all synthesis methods and higher incorrect rejection rates for the SEM model with univariate weighting procedures. 相似文献

Transfer to intermediate forms following concept discrimination by pigeons: chimeras and morphs 下载免费PDF全文
Two experiments examined pigeons' generalization to intermediate forms following training of concept discriminations. In Experiment 1, the training stimuli were sets of images of dogs and cats, and the transfer stimuli were head/body chimeras, which humans tend to categorize more readily in terms of the head part rather than the body part. In Experiment 2, the training stimuli were sets of images of heads of dogs and cats, and the intermediate stimuli were computer-generated morphs. In both experiments, pigeons learned the concept discrimination quickly and generalized with some decrement to novel instances of the categories. In both experiments, transfer tests were carried out with intermediate forms generated from both familiar and novel exemplars of the training sets. In Experiment 1, the pigeons' transfer performance, unlike that of human infants exposed to similar stimuli, was best predicted by the body part of the stimulus when the chimeras were formed from familiar exemplars. Spatial frequency analysis of the stimuli showed that the body parts were richer in high spatial frequencies than the head parts, so these data are consistent with the hypothesis that categorization is more dependent on local stimulus features in pigeons than in humans. There was no corresponding trend when the chimeras were formed from novel exemplars. In Experiment 2, when morphs of training stimuli were used, response rates declined smoothly as the proportion of the morph contributed by the positive stimulus fell, although results with morphs of novel stimuli were again less orderly. 相似文献

The rapidity with which infants come to understand language and events in their surroundings has prompted speculation concerning innate knowledge structures that guide language acquisition and object knowledge. Recently, however, evidence has emerged that by 8 months, infants can extract statistical patterns in auditory input that are based on transitional probabilities defining the sequencing of the input's components (Science 274 (1996) 1926). This finding suggests powerful learning mechanisms that are functional in infancy, and raises questions about the domain generality of such mechanisms. We habituated 2-, 5-, and 8-month-old infants to sequences of discrete visual stimuli whose ordering followed a statistically predictable pattern. The infants subsequently viewed the familiar pattern alternating with a novel sequence of identical stimulus components, and exhibited significantly greater interest in the novel sequence at all ages. These results provide support for the likelihood of domain general statistical learning in infancy, and imply that mechanisms designed to detect structure inherent in the environment may play an important role in cognitive development. 相似文献

Stroop effects in bilingual translation 总被引:2,自引:0,他引:2
In two experiments, bilinguals proficient in English and Spanish translated words from one language to the other. In each experiment, following the target word to be translated, distractor words were presented after a short (200-msec) or long (500-msec) stimulus onset asynchrony. In Experiment 1, the distractor words appeared in the language of production and were related to the meaning or form of the spoken translation. The results replicated past studies in demonstrating that semantically related distractor words produced Stroop-type interference, whereas form-related distractor words produced facilitation. In Experiment 2, the distractors appeared in the language of input and were related to the meaning or form of the target word itself. In contrast to the results of Experiment 1, there were only marginal effects of the distractors on translation performance. These results suggest that language cues related to the nature of the input in translation may serve to reduce competition among lexical competitors during lexicalization. The contrast between these results and those in bilingual picture-word interference studies provides important constraints for models of language production and for claims about the locus of language selection. 相似文献

We report three experiments designed to investigate the nature of any crossmodal links between audition and touch in sustained endogenous covert spatial attention, using the orthogonal spatial cuing paradigm. Participants discriminated the elevation (up vs. down) of auditory and tactile targets presented to either the left or the right of fixation. In Experiment 1, targets were expected on a particular side in just one modality; the results demonstrated that the participants could spatially shift their attention independently in both audition and touch. Experiment 2 demonstrated that when the participants were informed that targets were more likely to be on one side for both modalities, elevation judgments were faster on that side in both audition and touch. The participants were also able to "split" their auditory and tactile attention, albeit at some cost, when targets in the two modalities were expected on opposite sides. Similar results were also reported in Experiment 3 when participants adopted a crossed-hands posture, thus revealing that crossmodal links in audiotactile attention operate on a representation of space that is updated following posture change. These results are discussed in relation to previous findings regarding crossmodal links in audiovisual and visuotactile covert spatial attentional orienting. 相似文献

It is unclear from current accounts of working memory which, if any, of its components might be involved in our ability to specify the location of a sound source. A series of studies were performed to assess the degree of interference in localization of broadband noise, by a concurrent articulatory suppression (articulatory loop—Experiment 1), serial recall (phonological store and articulatory loop—Experiment 2), and Paced Visual Serial Addition Test (central executive—Experiment 3). No significant disruption of auditory localization was revealed by the first two experiments, ruling out a role for the phonological loop in auditory localization. In Experiment 3, a large degree of error was exhibited in localization, when performed concurrently with the addition task, indicating a requirement for central resources. This suggestion is confirmed by comparison of localization performance across all three studies, which demonstrates a clear deterioration in performance as the demand of concurrent tasks on central resources increases. Finally, concurrent localization was shown to disrupt the primacy portion of the serial position curve, as well as performance on the Paced Visual Serial Addition Test. 相似文献
