This four-experiment series sought to evaluate the potential of children with neurosensory deafness and cochlear implants to exhibit auditory-visual and visual-visual stimulus equivalence relations within a matching-to-sample format. Twelve children who became deaf prior to acquiring language (prelingual) and four who became deaf afterwards (postlingual) were studied. All children learned auditory-visual conditional discriminations and nearly all showed emergent equivalence relations. Naming tests, conducted with a subset of the children, showed no consistent relationship to the equivalence-test outcomes. This study makes several contributions to the literature on stimulus equivalence. First, it demonstrates that both pre- and postlingually deaf children can acquire auditory-visual equivalence relations after cochlear implantation, thus demonstrating symbolic functioning. Second, it directs attention to a population that may be especially interesting for researchers seeking to analyze the relationship between speaker and listener repertoires. Third, it demonstrates the feasibility of conducting experimental studies of stimulus control processes within the limitations of a hospital, which these children must visit routinely for the maintenance of their cochlear implants. 相似文献

Although much attention has been paid to patients who lack insight into their obsessional beliefs, less importance has been given to individuals with obsessive-compulsive disorder (OCD) who display perceptual disturbances typically found in psychotic disorders, including schizophrenia, schizoaffective disorders, or mood disorders with psychotic features. We would like to call the attention to a phenomenon that has been neglected in the psychiatric literature: the occurrence of hallucinations and related phenomena in patients with OCD. In this case report, we describe five clinical vignettes of patients with OCD with hallucinations in several different sensory modalities, including the auditory, the visual, the tactile, the olfactory, and the cenesthetic ones. Further psychopathological research should clarify the clinical significance of hallucinations among patients with OCD. 相似文献

This article describes Sarah-Pegworks, a computerized procedure for analyzing hand kinematics based on the peg-moving task. The procedure, developed in Visual Basic 6 programming language, includes (1) processing raw data from an infrared motion-tracking system, (2) identifying movement components, and (3) analyzing and presenting hand kinematic information in numerical and graphic outputs. Fifty-five normal adults set the parameters relative to filtering and movement identification. A case was presented to illustrate the clinical value of this procedure. 相似文献

The value of the results of the inverse dynamic analysis procedures used in the study of human tasks is dependent on the quality of the kinematic and kinetic data supplied to the biomechanical model that supports it. The kinematic data, containing the position, velocity and acceleration of all anatomical segments of the biomechanical model, result from the reconstruction of human spatial motion by means of the evaluation of the anatomic points positions that enable to uniquely define the position of all anatomical segments. Furthermore, the motion data must be kinematically consistent with the structure of the biomechanical model used in the analysis. The traditional photogrammetric methodologies used for the spatial reconstruction of the human motion require images of two or more calibrated and synchronized cameras. This is due to the fact that the projection of each anatomical point is described by two linear equations relating its three spatial coordinates with the two coordinates of the projected point. The need for the image of another camera arises from the fact that a third equation is necessary to find the original spatial position of the anatomical point. The methodology proposed here substitutes the projection equations of the second camera with the kinematic constraint equations associated with a biomechanical model in the motion reconstruction process. In the formulation the system of equations arising from the point projections and biomechanical model kinematic constraints, representing the constant length of the anatomical segments, are solved simultaneously. Because the system of equations has multiple solutions for each image, a strategy based on the minimization of a cost function associated to the smoothness of the reconstructed motion is devised. It is shown how the process is implemented computationally avoiding any operator intervention during the motion reconstruction for a given time period. This leads to an automated computer procedure that ensures the uniqueness of the reconstructed motion. The result of the reconstruction process is a set of data that is kinematically consistent with the biomechanical model used. Through applications of the proposed methodology to several sports exercises its benefits and shortcomings are discussed. 相似文献

This article assesses the similarity and difference betweenthe Western European style of doing bioethics and the Scandinavianone. First, it reviews the introductory article by the editor,C. Delkeskamp-Hayes in the first issue of Christian Bioethics(2008), devoted to the possibility of a specifically Christianbioethics in Europe. Second, it analyses bioethics debates inScandinavian today. In light of Delkeskamp-Hayes' article, themain similarity is that both regions are facing secularizationas a threat to basic Christian values, for example, to the Christianview of the sanctity and dignity of the human life. But theScandinavian tends to reduce Christian bioethics to Luther'sconcept of the worldly kingdom, supposed to foster a dialoguebetween Christians and non-Christians on controversial ethicalissues. Despite the positive value of the dialogue, this strategyrenders Christian ethics powerless. Third, from an evangelicaltheological standpoint, it proposes some strategies for enhancingthe influence of Christian commitments on bioethical laws andpolicies. 相似文献

The affective events theory proposes that daily events elicit affective reactions on workers that, over time, influence affective and judgement-driven behaviours. It also suggests that this relation is moderated by dispositions and appraisals. On the other hand, the social interaction model argues that the impact of emotions is moderated by how individuals regulate them. This study aimed to: (1) investigate what customer-related events elicit affect; (2) test the moderating role of workers’ susceptibility for emotional contagion on the relation events-affect; and (3) explore whether affective states influence cardiovascular efficiency and turnover intentions. We conducted a longitudinal study in an inbound call centre by following 48 workers during 10 working days, gathering 267 events and 1,232 affective reactions. We combined diaries, questionnaires and physiological data. Data was analysed qualitatively and quantitatively. We extracted 13 event categories and, using artificial neural networks (ANN), found support for the moderating role of emotional contagion. At daily level, fear was the stronger predictor of cardiovascular efficiency, whereas anger was the stronger predictor of turnover. ANN models showed satisfactory predictive values (R2Turnover = .51, p < .01; R2Cardiovascular efficiency = .32, p < .01). The importance of results for theory and practice is discussed. 相似文献

Black and minority ethnic (BME) men who have sex with men (MSM) face a major burden in relation to HIV infection. It was hypothesised that sexual abuse would predict sexual risk-taking, and that this relationship would be mediated by victimisation and maladaptive coping variables. Four hundred and thirty-two BME MSM completed the survey; 54% reported no sexual abuse and 27% reported sexual abuse. Mann–Whitney tests showed that MSM with a history of sexual abuse reported higher frequency of drug use, and of homophobia and racism than those reporting no prior sexual abuse. A structural equation model showed that the experience of sexual abuse was positively associated with sexual risk-taking and that this relationship was mediated by victimisation variables: frequency of racism and frequency of homophobia and by the maladaptive coping variable: frequency of drug use. The findings can inform the design of psycho-sexual and behavioural interventions for BME MSM. 相似文献

Influence of Additional Ankle Weights on Kinematic Variables of Late Preterm Infants Aged 3–4 Months
Jadiane Dionisio Gabriela Lopes dos Santos Eloisa Tudella 《Journal of motor behavior》2017,49(3):306-311
The authors analyzed and compared the effect of additional weight on the spatiotemporal parameters of the kicking movement of late preterm and full-term infants. The experiment was divided into 4 conditions: training, baseline, weight, and postweight. In the W condition, a weight of one third the lower limb mass was added to the infant's ankle. During the baseline and postweight conditions, the ankle weight was removed. Late preterm infants do not differ from full-term infants in relation to spatiotemporal variables at 3 and 4 months. However, during the weight condition, the straightness index and the hip-ankle and knee-ankle correlations decreased in the preterm infants at both ages. In contrast, the straightness index increased in the postweight condition compared to the baseline values at both ages. 相似文献
