Is the perceived present a predictive model of the objective present?

ABSTRACT

Processing latencies for coherent, high level percepts in vision are at least 100?ms and possibly as much as 500?ms. Processing latencies are less in other modalities, but still significant. This seems to imply that perception lags behind reality by an amount equal to the processing latency. It has been proposed that the brain can compensate for perceptual processing latencies by using the most recent available information to extrapolate forward, thereby constructing a model of what the world beyond the senses is like now. The present paper reviews several lines of evidence relating to this hypothesis, including the flash-lag effect, motion-induced position shifts, representational momentum, static visual illusions, and motion extrapolation at the retina. There are alternative explanations for most of the results but there are some findings for which no competing explanation has yet been proposed. Collectively, the evidence for extrapolation to the present is suggestive but not yet conclusive. An alternative account of compensation for processing latencies, based on the hypothesis of rapid emergence of percepts, is proposed.     

The effectiveness of enhanced cognitive behavioural therapy for eating disorders: an open trial

The aim of this study was to examine the effectiveness of Enhanced Cognitive Behaviour Therapy (CBT-E) for eating disorders in an open trial for adults with the full range of eating disorders found in the community. The only previously published trial of CBT-E for eating disorders was a randomised controlled trial (RCT) conducted in the U.K. for patients with a BMI ≥ 17.5. The current study represents the first published trial of CBT-E to include patients with a BMI < 17.5. The study involved 125 patients referred to a public outpatient clinic in Perth, Western Australia. Patients attended, on average, 20–40 individual sessions with a clinical psychologist. Of those who entered the trial, 53% completed treatment. Longer waiting time for treatment was significantly associated with drop out. By the end of treatment full remission (cessation of all key eating disorder behaviours, BMI ≥ 18.5 kg/m², not meeting DSM-IV criteria for an eating disorder) or partial remission (meeting at least 2 these criteria) was achieved by two thirds of the patients who completed treatment and 40% of the total sample. The results compared favourably to those reported in the previous RCT of CBT-E, with one exception being the higher drop-out rate in the current study. Overall, the findings indicated that CBT-E results in significant improvements, in both eating and more general psychopathology, in patients with all eating disorders attending an outpatient clinic.     

The Influence of Group Size and Stigma Severity on Social Acceptance: The Case of People with Intellectual Disability Moving into Neighbourhoods

Dutch adults from a nationwide Internet panel (N = 426) were asked to imagine that their next‐door neighbours would move out and that people with intellectual disability would move in. Severity of disability and group size were varied to manipulate intergroup threat. These two factors independently influenced social acceptance and a variety of emotional and behavioural measures. In particular, it was found that a large group with severe disability aroused the strongest negative response, whereas a small group with mild disability aroused the weakest negative response. Small groups with a severe disability and large groups with a mild disability aroused similar and intermediate negative responses. Results are discussed in terms of theories of intergroup threat and stigmatisation. Practical implications for predicting the success of de‐institutionalisation and social integration of groups with special needs are addressed. Copyright © 2011 John Wiley & Sons, Ltd.

大学生领悟社会支持的影响因素研究

该研究以371名大学生为被试,考察了个体的幸福感、控制感和压力对领悟社会支持的影响。结构方程模型分析的结果显示：个体属性和情境因素都直接或间接影响着大学生对社会支持的理解和评价;个体属性的影响相对比较重要;在情境因素中,累积压力比当前压力的影响更为重要。本研究结果表明,领悟社会支持是在个人属性的作用下,个体在不断应对日常生活压力的过程中形成和发展的。     

普通高等医学院校人文医学教育的现状与思考

人文医学教育是高等医学教育的重要组成部分,也是医学发展、医学人才培养的内在要求。普通高等医学院校在这项工作中存在着不足,如课程体系不完善、课程结构不合理、人文气氛短缺等。因此,有必要采取一些措施予以完善,从而跟上国家高等医学教育改革的步伐,促进医学教育的进一步完善。     

论时间洞察力

时间洞察力既是能力特质也是动力特质,是个体对时间的认知、体验和行动(或行动倾向)的人格特质,它可以区分为过去时间洞察力、现在时间洞察力、未来时间洞察力,也可以区分为特质时间洞察力和状态时间洞察力。时间洞察力是决定个人事业与人生成功的关键因素。我们已开始用多维度-多方法对时间洞察力开展深入的研究。
