Children's lie-telling is surprisingly understudied among children with significant behavioral problems. In the present study, experimental paradigms were used to examine antisocial lie-telling among ethnically diverse 5- to 10-year-old children with disruptive behavior disorders (DBD;= 71) and a typically developing (TD) comparison sample (= 50) recruited from a southeastern state from 2013 to 2014. Children completed two games that measured the prevalence and skill of their lies: (a) for personal gain and (b) to conceal wrongdoing. Children with DBD were more likely to lie for personal gain than TD children. With age, children were more likely to lie to conceal wrongdoing, but the reverse was true regarding lies for personal gain. Results advance knowledge concerning individual differences in children's lie-telling.  相似文献

We examined sport expertise as a function of role. In study 1, referees were better than players in a video-based decision-making task. This provides evidence that there are role-specific skills within one domain or sport. In study 2, we examined the training activities that could be influential in the development of skills in sports officials. Elite association football (soccer) referees retrospectively reported time spent in and perceptions of training activities for three periods: their first year of formal refereeing, 1998 (before formal training programmes were available), and the current year (2003). This allowed us to examine an area of skill with a limited culture of practice, where performance simulations with direct feedback are usually not feasible. The results showed that referees specialize early and, as they develop, they engage in greater volumes and types of training. Competitive match refereeing is considered a relevant activity for skill acquisition that does not fit Ericsson and colleagues' (1993) original definition of deliberate practice. Our findings indicate that actual performance is a significant activity for skill acquisition and refinement.  相似文献

This paper analyses the main forms of government intervention used in the UK to protect the national artistic patrimony. It examines the two most common policy measures used in the art market ‐ export regulation and tax incentives ‐ and reports their use over an eight‐year period from 1990 to 1998. It also reviews the UK's collective obligations to patrimony internationally and specifically as a member of the European Union. This is the first time that these related topics have been considered as a whole.  相似文献

Dinosaur reconstructions have been exhibited in public for over a hundred years. During that time, scientific and public understanding of these extinct animals has changed considerably. Changes in perception have influenced and been influenced by the three-dimensional reconstructions mounted in museums and galleries, and these in turn have been influenced by the availability and use of mounting materials and techniques. The dinosaur exhibition in The Natural History Museum (NHM) in London contains examples of original, altered, and new dinosaur reconstructions that are described here—two, Gallimimus and Massospondylus, in detail. The final form of any reconstructed dinosaur is often influenced by factors beyond the control of the conservation, preparation, and mounting workers involved.  相似文献

Baseball umpires, players, and control participants with no baseball experience were asked to call balls and strikes for video clips. In a basic judgement task, umpires and players were significantly better at calling pitches than controls. In a direct information task, borderline pitches were presented following clips of definite balls and definite strikes. Participants called target pitches closer to the strike end of the scale when viewed after definite balls than when they followed definite strikes. Similarly, when borderline pitches were shown in different pitch counts, participants called pitches more towards the strike end of the scale when there were three balls in the count (3-0, 3-2). These findings indicate that the standard for evaluation changes based on the context in which stimuli are processed. Moreover, the strength of the contextual factors is illustrated in that the effects were shown in observers with and without experience in the task. Overall, however, umpires had a greater tendency to call strikes, indicating that they may use a norm of "hastening the game".  相似文献

To determine gender differences, positional differences, and patterns of change in the performance of the basketball line-drill test, 93 male (mean age 16.8 years, s = 1.1) and 95 female (mean age 16.5 years, s = 1.0) basketball players undertook 516 line-drill tests over a 5-year period. Log-transformed performance times were analysed using a mixed model that included quadratic within-participant fixed effects for time in the season and time in the programme. Changes and differences were standardized for interpretation of magnitudes. Mean performance times were 28.0 s (s = 1.3) for males and 30.4 s (s = 1.3) for females. The mean pattern of change in performance within a season differed substantially between the sexes and playing positions: male guards and female centres showed moderate to very large improvements mid-season of 1.1% and 3.5% respectively (90% confidence limits +/-2.1% and +/-3.0%), while female guards and male forwards showed large to very large decrements of -1.6% (+/-2.6%) and -2.4% (+/-2.0%). Over 3 years, males improved performance across all three playing positions by 1.4% (+/-1.3%) and females by 2.9% (+/-1.4%). Males improved performance by 0.2% (+/-0.5%) per year, whereas the performance of females deteriorated by 0.6% (+/-0.4%) per year. The differing patterns of performance change presumably reflect variations in training and competition loads, with short-term fluctuations in performance being managed to promote longer-term improvements.  相似文献

Clinical and diagnostic approaches to special educational needs do not translate easily into educational models. In some cases, these approaches can serve to limit understanding of children's wider needs. Children with specific speech and language difficulties (SSLD) are a case in point. Clear criteria exist for identification, but identification mechanisms may not relate to the child's wider educational needs. This paper addresses the ways that children with SSLD present in mainstream educational settings. The study aimed to identify all Year 3 children with SSLD in two English local education authorities. One hundred and thirty-three children (95 boys and 37 girls were identified). Sixty-five per cent of the children were in mainstream schools, 14.3 per cent in mainstream schools with designated units and the remainder in special schools. Half were at stage 5 of the Code of Practice, with most of the remaining participants at stage 3. Children experienced a wide range of difficulties, in addition to their primary speech and language problems. Patterns of difficulties varied across children, and associations existed between particular forms of language problems and learning and relationship problems. Professionals (teachers, educational psychologists and speech and language therapists) varied in their understanding of the children's needs. The data highlight the range and diversity of the needs of children with specific speech and language difficulties and the need for a multi-professional approach to these children. It is argued that ‘best practice’ for these children must consider the impact of speech and language problems on children's access to the curriculum and their social and behavioural needs. Narrow diagnostic models do not provide the appropriate information to inform educational practice and support inclusive policies.  相似文献

Despite an increased awareness over the last few years of the unique historic, cultural and artistic value of historic designed landscapes, parks and gardens, few hard facts and figures appeared to be available relating to their undoubted economic contribution. With this in mind, the Garden History Society announced its intention to host a conference in late 2001 on the economic contribution of historic parks and gardens and, with support from the Heritage Lottery Fund, commissioned the following study.

The study's objective was to review and analyse existing research and data on the economic contribution of historic parks and gardens, and to make recommendations for a range of research projects to fill any gaps identified.

The report first sets historic parks and gardens within the wider context of the ‘gardens and gardening’ market generally; it then deals with the economic impact of tourism, recreation and leisure at historic parks and gardens and then with the economic contribution of public parks with particular regard to the latter's role in promoting regeneration of the local area. The applicability of various non‐market valuation techniques is considered in relation to free‐entry parks and gardens. Finally, specific research recommendations are set out to cover stocktaking, the visitor attraction sector, local area regeneration and the valuation of non‐market sites.  相似文献
