Effects of unilateral hippocampus-amygdala-partial temporal lobe resection on auditory EEG/MEG responses: a case study

Auditory orienting and discrimination were studied with combined multi-channel EEG and MEG recordings in a patient with unilateral amygdala-hippocampus-partial temporal lobe resection of the right hemisphere. The results revealed abnormalities of habituation in alerting- and orienting-related responses, and discrimination-related responses, elicited by auditory stimulation contralateral to the resected cerebral hemisphere. These results give support to the notions about the role of the amygdala and hippocampus in alerting and orienting, respectively, and of the temporal cortex in auditory discrimination.     

Parafoveal-on-foveal interactions in word recognition

An experiment is reported in which participants read sequences of five words, looking for items describing articles of clothing. The third and fourth words in critical sequences were defined as "foveal" and "parafoveal" words, respectively. The length and frequency of foveal words and the length, frequency, and initial-letter constraint of parafoveal words were manipulated. Gaze and refixation rate on the foveal word were measured as a function of properties of the parafoveal word. The results show that measured gaze on a given foveal word is systematically modulated by properties of an unfixated parafoveal word. It is suggested that apparent inconsistencies in previous studies of parafoveal-on-foveal effects relate to a failure to control for foveal word length and hence the visibility of parafoveal words. A serial-sequential attention-switching model of eye movement control cannot account for the pattern of obtained effects. The data are also incompatible with various forms of parallel-processing model. They are best accounted for by postulating a process-monitoring mechanism, sensitive to the simultaneous rate of acquisition of information from foveal and parafoveal sources.     

解决“乙肝”问题亟须“四化”

乙型病毒性肝炎是一个严重的社会问题,而不是简单的医患之间的医疗和接受医疗的问题,它涉及到医疗机构、制药厂家以及社会、家庭、婚姻、就业等很多问题。要想从根本上解决乙型病毒性肝炎所带来的诸多问题需要全社会共同努力,形成一种“社会监督法制化、诊疗方案规范化、社会关爱人性化、具体施治个性化”的格局。     

超常儿童实验班的建立——关于学生筛选的研究

本研究根据鉴别超常儿童要采取多指标、多途径、多种方法以及与常态儿童进行动态比较的原则探讨了对超常儿童实验班的筛选方法。先由教师和家长推荐,再用八项测查指标综合考察。并设立了同龄对比班。为今后大范围筛选超常儿童作了有效的尝试。同时.对超常儿童认知能力特点、学业成绩、教师评价、家庭背景等方面作了分析研究。     

新疆维吾尔、哈萨克、回族519名男青年试用EPQ问卷的初步报告

本文报告以维吾尔(简称维)、哈萨克(简称哈)、汉语EPQ问卷对新疆维、哈、回族519名16～29岁男青年的测查结果。表明EPQ各量表间相关情况和总趋势与英国、龚氏常模相似,P量表分均为最低;L量表分与龚氏常模一样均为最高。维、哈族个性特征显著外倾,尤以哈族突出。提出民族的历史发展、社会文化传统、劳动生活方式等因素是形成维、哈族个性特征的基础,认为龚氏常模及其划界分需进一步修订和完善。     

Organizational self-evaluation: An emerging frontier for organizational improvement

The authors have been working to improve clients’ institutional performance through a framework for institutional assessment and self-assessment. In this framework, performance is defined in terms of mission fulfillment, efficiency, and ongoing relevance (the extent to which the organization adapts to changing conditions in its environment). The framework implies that certain contextual forces drive performance: the internal capacities and motivation of an organization and its external environment. The article presents the framework as well as case studies of several institutions that are using the framework to assess themselves.
