Patients with right unilateral cerebral stroke, four of which showed acute hemispatial neglect, and healthy aged-matched controls were tested for their ability to grasp objects located in either right or left space at near or far distances. Reaches were performed either in free vision or without visual feedback from the hand or target object. It was found that the patient group showed normal grasp kinematics with respect to maximum grip aperture, grip orientation, and the time taken to reach the maximum grip aperture. Analysis of hand path curvature showed that control subjects produced straighter right hand reaches when vision was available compared to when it was not. The right hemisphere lesioned patients, however, showed similar levels of curvature in each of these conditions. No behavioural differences, though, could be found between right hemisphere lesioned patients with or without hemispatial neglect on either grasp parameters, path deviation or temporal kinematics.  相似文献

The human central auditory system has a remarkable ability to establish memory traces for invariant features in the acoustic environment despite continual acoustic variations in the sounds heard. By recording the memory-related mismatch negativity (MMN) component of the auditory electric and magnetic brain responses as well as behavioral performance, we investigated how subjects learn to discriminate changes in a melodic pattern presented at several frequency levels. In addition, we explored whether musical expertise facilitates this learning. Our data show that especially musicians who perform music primarily without a score learn easily to detect contour changes in a melodic pattern presented at variable frequency levels. After learning, their auditory cortex detects these changes even when their attention is directed away from the sounds. The present results thus show that, after perceptual learning during attentive listening has taken place, changes in a highly complex auditory pattern can be detected automatically by the human auditory cortex and, further, that this process is facilitated by musical expertise.  相似文献

Idiopathic environmental intolerance (IEI) refers to a health condition characterized by the presence of multiple symptoms in different organ systems in response to a variety of environmental cues, such as chemical exposures, electromagnetic radiation, infrasound from windmill farms, (parts of) buildings, foods, etc. Typically, the symptoms arise in response to triggers and at dosages that do not cause symptoms in the majority of people, and no clear link with any physiological dysfunction can be found. The condition varies in a dimensional way from very mild, for which no medical help is sought, to very disabling, compromising normal life. The condition is controversial, but several indications strongly suggest that the symptoms result from nocebo mechanisms. Currently, different psychological treatments are explored, but they are generally not based on a clear understanding of the aetiopathological mechanisms and the treatment effects are not well documented. In the present paper, we describe a treatment protocol based on a comprehensive explanatory model of IEI. The goal is to contribute to standardized, mechanism-based treatments as a basis for more systematic treatment studies.  相似文献

Normative theories aim to explain why things have the normative features they have. This paper argues that, contrary to some plausible existing views, one important kind of normative explanations which first-order normative theories aim to formulate and defend can fail to transmit downward along chains of metaphysical determination of normative facts by non-normative facts. Normative explanation is plausibly subject to a kind of a justification condition whose satisfaction may fail to transmit along the relevant kind of metaphysical hierarchy. A broader aim of the paper is to contribute to systematic theorizing about normative explanation: whereas there has been a great deal of work on scientific explanation, there has been little by way of systematic exploration of what sort of explanations normative theories aim to formulate and defend.  相似文献

Background/ObjectiveLong-term childhood cancer survivors (CCS) are at risk for adverse late effects. However, not all of them are well understood. The present study addressed loneliness, a previously under-researched mental health risk in cancer survivor populations. We assessed the prevalence of loneliness and its impact on psychological symptoms over time. Method: A registry-based sample of N = 633 adult long-term CCS underwent medical and psychological assessments and took part in a follow-up survey 2.5 years later. Psychological symptoms (somatic, anxiety, depression symptoms, and suicidal ideation) were measured using the Patient Health Questionnaire. We calculated linear regression models of symptoms at follow-up to investigate the impact of loneliness over time (controlling for symptoms at baseline and relevant confounders). Results: Loneliness was reported by 17.70% of CCS. In multivariate linear regression analyses, loneliness was still predictive of more severe anxiety symptoms and suicidal ideation over two years later. Loneliness did not predict somatic and depression symptoms at follow-up (which increased with age). Conclusions: Loneliness affected a significant number of CCS and was a risk factor for persistent anxiety symptoms and suicidal ideation. The extent to which young cancer patients’ re-integration into society is successful could thus have important implications for well-being in adulthood.  相似文献

Previous research has found a complex relationship between psychopathic traits, neurodevelopmental problems (NDPs), and conduct disorder (CD) in children. This study explores associations between psychopathic traits, assessed with the Child Problematic Traits Inventory—Short Version (CPTI-SV), and CD in children with and without coexisting NDPs (i.e., attention deficit/hyperactivity disorder [ADHD] and autism spectrum disorder [ASD]) in a community-based sample of Swedish twins (n?=?8762). Findings indicate weak to moderately strong correlations between psychopathic traits and CD, ADHD, and ASD, respectively. Furthermore, in univariable analyses, both psychopathic traits and NDPs displayed significant positive associations with being screened positive for CD, though only the grandiose-deceitful dimension of CPTI-SV and the ADHD domain concentration and attention deficits remained significantly associated with CD in a multivariable regression model. The results are relevant to screening and assessment in child and youth psychiatry, as a grandiose and deceitful interpersonal style may also be a valid sign of children at risk of developing CD.  相似文献
