The nonvisual self-touch rubber hand paradigm elicits the compelling illusion that one is touching one’s own hand even though the two hands are not in contact. In four experiments, we investigated spatial limits of distance (15 cm, 30 cm, 45 cm, 60 cm) and alignment (0°, 90° anti-clockwise) on the nonvisual self-touch illusion and the well-known visual rubber hand illusion. Common procedures (synchronous and asynchronous stimulation administered for 60 s with the prosthetic hand at body midline) and common assessment methods were used. Subjective experience of the illusion was assessed by agreement ratings for statements on a questionnaire and time of illusion onset. The nonvisual self-touch illusion was diminished though never abolished by distance and alignment manipulations, whereas the visual rubber hand illusion was more robust against these manipulations. We assessed proprioceptive drift, and implications of a double dissociation between subjective experience of the illusion and proprioceptive drift are discussed. 相似文献

In the South American Republic of Chile genetic counseling is not currently recognized as an independent clinical discipline, and in general is provided by physicians with training in clinical genetics. At present only one genetic counselor and 28 clinical geneticists practice in this country of over 16 million inhabitants. Pediatric dysmorphology constitutes the primary area of practice in clinical genetics. Although the country has a universal health care system and an adequate level of health care, genetic conditions are not considered a health care priority and there is a lack of clinical and laboratory resources designated for clinical genetics services. Multiple educational, cultural and financial barriers exist to the growth and development of genetic counseling services in Chile. However, during the last 10 years increased awareness of the importance of identifying individuals at risk for inherited cancer syndromes led to growing interest in the practice of cancer genetics. 相似文献

Strength training is often prescribed for children with cerebral palsy (CP); however, links between strength gains and mobility are unclear. Nine children (age 14?±?3?years; GMFCS I-III) with spastic CP completed a 6-week strength-training program. Musculoskeletal gait simulations were generated for four children to assess training effects on muscle forces and function. There were increases in isometric joint strength, but no statistical changes in fast-as-possible walking speed or endurance after training. The walking simulations revealed changes in muscle forces and contributions to body center of mass acceleration, with greater forces from the hip muscles during walking most commonly observed. A progressive strength-training program can result in isometric and dynamic strength gains in children with CP, associated with variable mobility outcomes. 相似文献

In three experiments, we tested the influence of instructions about an allegedly upcoming extinction or counterconditioning phase on evaluative conditioning (EC) effects. After an acquisition phase in which neutral stimuli were related to positive or negative stimuli via instructions (Experiments 1 and 2a) or actual pairings (Experiment 2b), three different groups of participants were either informed that in the next phase the neutral stimuli would be presented without positive or negative stimuli (extinction instruction), that the neutral stimuli in the next phase would be paired with stimuli of the opposite valence than before (counterconditioning instruction), or received no further instructions. Afterwards, liking of the originally neutral stimuli was measured either with an evaluative rating (Experiment 1) or with an Implicit Association Test (IAT; Experiments 2a and 2b). EC was reduced in the counterconditioning condition of Experiment 1 and in the joint analysis of Experiments 2a and 2b. The extinction instruction led to a reduction of EC only in Experiment 1. Finally, whether the acquisition phase consisted of instructions about CS–US pairings (Experiment 2a) or the actual experience of CS–US pairings (Experiment 2b) did not significantly impact the observed changes in liking. Overall, our results suggest that similar mechanisms might mediate instruction- and experienced-based EC. Our results are in line with propositional models of EC but can be explained also by association formation models and dual process models of EC, provided that certain auxiliary assumptions are made. 相似文献

The Complete State Model of Mental Health was used to describe the prevalence of flourishing, languishing, struggling, and floundering in life in a sample of young South Australians (n = 3,913; 13–17 years, 52% female). Categorisation was based on the relative proportion of mental health and mental illness symptoms reported on standardised measures and the association of these categories to health‐risk behaviour. Variability in categories and health‐risk behaviour due to gender or region was investigated. Results indicated that a disturbingly small proportion of adolescents (<50%) were flourishing in life, that poorer states of mental health were associated with increased health‐risk behaviour, and that the propensity to engage in health‐risk behaviour did vary by gender and region. The current study extends the platform from which positively focused mental health strategies can be tailored and launched to meet the mental health needs of adolescents. 相似文献

The authors studied the performances of 8- to 13-year-old skilled (n = 30) and less skilled (n = 30) gymnasts on a gymnastics routine recall task by examining the role of memorization strategies and imagery ability. Subjects had to reproduce 3 movement sequences presented on videotape. The number of trials needed to achieve correct recall, the strategies employed, and the subjects' imagery ability were analyzed. Recall performance improved with age and skill level. Movement labeling was the most prevalent strategy used; its frequency increased with age, although it did not lead to better recall performance. Performance was higher, however, among subjects with better imagery skills. The role of strategy development in the age-related improvement in memory performance was not clearly demonstrated. The effect of skill level is interpreted in terms of knowledge bases and kinesthetic movement encoding. 相似文献

A battery of 10 traditional paper-and-pencil aptitude tests and a battery of 25 cognitive-components-based tests were administered to 298 men and women to investigate the common sources of variance in those batteries. Earlier confirmatory factor analyses showed each battery to have a hierarchical structure, each with a single higher order factor. The higher order factor in the paper-and-pencil battery had previously been identified as general cognitive ability, or g. The higher order factor from the cognitive-components battery had been identified as working memory. The intercorrelation of the higher order factors from the two batteries was .994, indicating that both measured g. The proportion of common variance because of g was greater in the cognitive-components battery than in the paper-and-pencil battery. The correlations between each factor based on cognitive components and g averaged .946. Despite theoretical foundations and arguments, cognitive components tests appear to measure much the same thing as traditional paper-and-pencil tests. 相似文献
