Previous studies have shown the appearance of right-sided language-related brain activity in right-handed patients after a stroke. Non-invasive brain stimulation such as transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) have been shown to modulate excitability in the brain. Moreover, rTMS and tDCS have been found to improve naming in non-fluent post-stroke aphasic patients. Here, we investigated the effect of tDCS on the comprehension of aphasic patients with subacute stroke. We hypothesized that tDCS applied to the left superior temporal gyrus (Wernicke’s area) or the right Wernicke’s area might be associated with recovery of comprehension ability in aphasic patients with subacute stroke. Participants included right-handed subacute stroke patients with global aphasia due to ischemic infarct of the left M1 or M2 middle cerebral artery. Patients were randomly divided into three groups: patients who received anodal tDCS applied to the left superior temporal gyrus, patients who received cathodal tDCS applied to the right superior temporal gyrus, and patients who received sham tDCS. All patients received conventional speech and language therapy during each period of tDCS application. The Korean-Western Aphasia Battery (K-WAB) was used to assess all patients before and after tDCS sessions. After intervention, all patients had significant improvements in aphasia quotients, spontaneous speech, and auditory verbal comprehension. However, auditory verbal comprehension improved significantly more in patients treated with a cathode, as compared to patients in the other groups. These results are consistent with the role of Wernicke’s area in language comprehension and the therapeutic effect that cathodal tDCS has on aphasia patients with subacute stroke, suggesting that tDCS may be an adjuvant treatment approach for aphasia rehabilitation therapy in patients in an early stage of stroke. 相似文献

This study investigated the EMG characteristics and the kinematics of the trunk and lower extremity during the sit-to-stand (STS) task while wearing 1-, 4-, and 8-cm high-heeled shoes. We examined differences in the EMG data of the internal oblique, erector spinae, medial hamstring, and rectus femoris muscles during the STS task. The motion of the hip joint during an STS task was measured with a NorAngle Electrogoniometer System. Twelve young healthy women were recruited to this study. EMG characteristics and the hip joint angle were recorded during the performance of an STS task by subjects wearing high-heeled shoes of three different heel heights. The muscle onset time and EMG activity during this task were analyzed. In 8-cm high-heeled shoes, the onset time for the erector spinae muscle was significantly delayed, and the onset latency for the medial hamstring and the rectus femoris was significantly decreased. There was increased activity in the erector spinae and rectus femoris muscle during this task when wearing 8-cm high-heeled shoes. The initial hip flexion angle at the start point of the STS task did not differ among the 1-, 4-, and 8-cm heel-height conditions, but the trunk flexion angle, corresponding to the displacement between the peak hip flexion and initial hip flexion, was significantly larger in the 8-cm heel-height condition than in the 1- and 4-cm heel-height conditions. The findings suggest that excessive heel height has the potential to induce muscle imbalance during the STS task. 相似文献

Research over the past few years has uncovered a consistent link between the reporting of intense negative life events and interrogative suggestibility on the Gudjonsson Suggestibility Scale (GSS). This study (N = 130) now investigates the functional form of this relationship. Findings show that a linear regression model provides the most acceptable fit to the observed values for yield 1, yield 2, shift and total suggestibility scores. However, results also show the presence of non linear, quadratic, aspects to the relationship between the experience of life adversity and yield 1 scores. Up until now GSS scores were thought to increase linearly with level of adversity experienced: this study provides some evidence that, for the yield 1 subscale of the GSS, this may not be the case – high levels of adversity may not necessarily lead to an increased risk of accepting misleading information during questioning as once presumed. 相似文献

Statistical methodology for handling omitted variables is presented in a multilevel modeling framework. In many nonexperimental
studies, the analyst may not have access to all requisite variables, and this omission may lead to biased estimates of model
parameters. By exploiting the hierarchical nature of multilevel data, a battery of statistical tools are developed to test
various forms of model misspecification as well as to obtain estimators that are robust to the presence of omitted variables.
The methodology allows for tests of omitted effects at single and multiple levels. The paper also introduces intermediate-level
tests; these are tests for omitted effects at a single level, regardless of the presence of omitted effects at a higher level.
A simulation study shows, not surprisingly, that the omission of variables yields bias in both regression coefficients and
variance components; it also suggests that omitted effects at lower levels may cause more severe bias than at higher levels.
Important factors resulting in bias were found to be the level of an omitted variable, its effect size, and sample size. A
real data study illustrates that an omitted variable at one level may yield biased estimators at any level and, in this study,
one cannot obtain reliable estimates for school-level variables when omitted child effects exist. However, robust estimators
may provide unbiased estimates for effects of interest even when the efficient estimators fail, and the one-degree-of-freedom
test helps one to understand where the problem is located. It is argued that multilevel data typically contain rich information
to deal with omitted variables, offering yet another appealing reason for the use of multilevel models in the social sciences.

Although mental accounting principles are generally robust, the integration‐of‐losses principle often fails. This research argues that when information salience is high, people actively segregate. To demonstrate that effect, this research uses purchase decision making for which the total payment is a key decision factor and compares examples such as the following equivalent total payments: “$120.95 for a stroller plus $19.95 for shipping” (i.e., segregation) versus “$140.90 for a stroller including shipping” (i.e., integration). Two studies demonstrate that integration increases purchase intentions when the salience of the smaller payment is higher. Specifically, integration leads to higher purchase intentions than does segregation when (1) the surcharge is visually more salient, (2) the surcharge is easy to process, and (3) price perceptions are stimulus instead of recall driven. Therefore, this research extends mental accounting by identifying conditions in which the integration‐of‐losses principle is likely to prevail. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

Health locus of control (HLC) beliefs may influence the health behaviors that patients perform on their own behalf. Likewise, the HLC beliefs that clinicians consider desirable may influence how active they encourage patients to be in managing health. It remains unclear how involved lung recipients want to be and how involved transplant clinicians believe they should be. The aims of this study were to describe HLC beliefs and behaviors manifested by recipients and clinicians in the setting of lung transplantation. Mixed-methods were used, including quantitative techniques to measure demographics, clinical characteristics, and HLC using the Multidimensional Health Locus of Control Scale (MHLC), and qualitative techniques to explore how HLC beliefs were manifest in the clinical setting. Nearly all participants manifested behaviors consistent with high internality and externality, highlighting the importance of holding ‘dual health locus of control’ beliefs for optimal health management and lending support for recipients and clinicians to share responsibility for managing post-transplant health.Funded by the Nursing & Social Sciences Council of the International Society of Heart and Lung Transplantation. 相似文献

Abstract. An historically familiar tension in East Asian Buddhism between meditation and cultivation in broad learning has appeared in discussions and planning for preparing ministerial students in Won Buddhism. This paper reviews the history of preparation in this order, which was founded in 1916. While the alternatives of training based on practice and education based on classroom intellectual experience have occurred in Won Buddhism, the tension has appeared within the recently founded Won Institute of Graduate Studies in the USA in a clear manner. While the pre‐ministerial students coming from Korea have preferred the experiential/practical emphasis, it is recognized that graduate education in the USA normally requires broader learning and critical thinking. The faculty of Won Institute respects both strategies and their respective, almost incompatible, goals, and has tried to create a curriculum embracing both. This effort is described and viewed in the context of Won participation in a culture of pluralism and interreligious relations. 相似文献
