A growing number of people are seeking health recovery treatments with a holistic approach to the human being. Meditation is a mental training capable of producing connection between the mind, body and spirit. Its practice helps people to achieve balance, relaxation and self-control, in addition to the development of consciousness. At present, meditation is classified as a complementary and integrative technique in the area of health. The purpose of this review of the literature was to describe what meditation is, its practices and effects on health, demonstrated by consistent scientific investigations. Recently, the advances in researches with meditation, the discovery of its potential as an instrument of self-regulation of the human body and its benefits to health have shown that it is a consistent alternative therapy when associated with conventional medical treatments. 相似文献

Visual attention in adolescents: Facilitating effects of sport expertise and acute physical exercise
Lucio Cereatti Rita Casella Manuela Manganelli Caterina Pesce 《Psychology of sport and exercise》2009,10(1):136-145
ObjectivesThis study investigated visual attention of adolescent orienteers and physically active adolescents non-practising orienteering both at rest and under acute sub-maximal exercise. It was verified whether the practice of orienteering facilitates the development of visual attentional abilities and whether orienteers, who are used to simultaneously handle physiological and cognitive-attentional loads, may better profit than non-orienteers from the beneficial effects of sub-maximal physical load on processing speed.MethodsBoth the focusing of attention at foveal and parafoveal locations and the orienting of attention at peripheral locations were investigated. In two discriminative reaction time (RT) experiments, a cue of varying size was presented centrally or peripherally and followed by a compound stimulus with local and global target features. The stimulus-onset asynchrony (SOA) varied between a short and a long interval.ResultsIn both experiments, adolescent orienteers and non-practisers showed different patterns of attentional effects. Adolescent orienteers were more similar to young adults in the attentional performance, being better able than non-practisers to perform complex attentional operations involving the intentional zooming of attention in the central visual field and the orienting of the attentional focus in the peripheral visual field. Also, both orienteers and non-orienteers speeded up their performance during exercise, but this facilitation effect was more pronounced for orienteers, who are probably skilled in directing the available resources to task demands.ConclusionsOur results suggest that cognitive expertise represents a key factor in sports that accelerates the development of visual attention and enhances the facilitating effects of physical exercise on attentional performance. 相似文献

This study describes the construction of a self-response inventory to evaluate the perception of advantages and disadvantages of the Machado-Joseph disease presymptomatic testing, in 44 individuals at-risk for this disease. The results showed that the reliability of this inventory was satisfactory. Factor analysis revealed a bidimensional structure: perceived advantages (pros) and perceived disadvantages (cons) of presymptomatic testing. Social desirability was found unrelated to the total scores of our inventory. Additional correlation studies, with other scales, confirmed the convergent validity of the instrument. These results suggest adequate construct validity. This inventory thus seems to be a proper instrument to assess expectations involved in the decision-making process of Machado-Joseph disease presymptomatic testing. 相似文献

Patients with unilateral (left or right) medial temporal lobe lesions and normal control (NC) volunteers participated in two experiments, both using a duration bisection procedure. Experiment 1 assessed discrimination of auditory and visual signal durations ranging from 2 to 8 s, in the same test session. Patients and NC participants judged auditory signals as longer than equivalent duration visual signals. The difference between auditory and visual time discrimination was equivalent for the three groups, suggesting that a unilateral temporal lobe resection does not modulate the modality effect. To document interval-timing abilities after temporal lobe resection for different duration ranges, Experiment 2 investigated the discrimination of brief, 50-200 ms, auditory durations in the same patients. Overall, patients with right temporal lobe resection were found to have more variable duration judgments across both signal modality and duration range. These findings suggest the involvement of the right temporal lobe at the level of the decision process in temporal discriminations. 相似文献

A converging body of evidence from neuroimaging, behavioral, and neuropsychology studies suggests that different arithmetic operations rely on distinct neuro-cognitive processes: while addition and subtraction may rely more on visuospatial reasoning, multiplication would depend more on verbal abilities. In this paper, we tested this hypothesis in a longitudinal study measuring language and visuospatial skills in 358 preschoolers, and testing their mental calculation skills at the beginning of middle school. Language skills at 5.5 years significantly predicted multiplication, but not addition nor subtraction scores at 11.5 years. Conversely, early visuospatial skills predicted addition and subtraction, but not multiplication scores. These results provide strong support for the existence of a double dissociation in mental arithmetic operations, and demonstrate the existence of long-lasting links between language/visuospatial skills and specific calculation abilities. 相似文献

This paper reports two studies examining how (in‐) congruence between personal and group outcomes affects emotional well‐being, outcome attributions and procedural justice perceptions of individuals who are exposed to subtle discrimination. In Study 1 (N = 82) participants are either accepted or rejected in a (bogus) job application procedure, and either do or do not receive additional information indicating group‐level disadvantage. In Study 2 (N = 79), participants were either accepted or rejected, and received information indicating either advantage or disadvantage for members of their group. Results of both studies reveal that not only emotional well‐being and outcome attributions, but also procedural justice perceptions are primarily guided by personal outcomes. That is, being informed of group‐level disadvantage does not intensify but can instead alleviate negative affect resulting from personal rejection. Furthermore, group disadvantage is only seen as an indicator of an unjust procedure by individual group members who have personally suffered rejection. Results are discussed in relation to current insights on discrimination, tokenism and social justice. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Subitizing is the immediate apprehension of the exact number of items in small sets. Despite more than a 100 years of research around this phenomenon, its nature and origin are still unknown. One view posits that it reflects a number estimation process common for small and large sets, which precision decreases as the number of items increases, according to Weber’s law. Another view proposes that it reflects a non-numerical mechanism of visual indexing of multiple objects in parallel that is limited in capacity. In a previous research we have gathered evidence against the Weberian estimation hypothesis. Here we provide first direct evidence for the alternative object indexing hypothesis, and show that subitizing reflects a domain general mechanism shared with other tasks that require multiple object individuation. 相似文献
