当代大学生对竞争认识的调查研究 总被引:4,自引:0,他引:4
以天津市和广州市532名大学生为被试,采用半开放式问卷,采用团体测试的方式,研究了他们对竞争的认识,并对这种认识进行了理论分析。研究结果发现:(1)大学生由竞争一词最易联想到“激烈”、“残酷”、“公平或不公平”、“压力或动力”等内容;(2)大学生认为竞争存在的领域从高到低依次是商业与市场经济、就业与工作、比赛与体育运动、学习与考试、国家与社会等;(3)大学生认为竞争是“激烈”、“残酷”、“对抗”等;(4)大学生认为竞争的主要作用是动力、压力和机遇或挑战;(5)大学生对竞争性质的认识存在显著的性别差异和地区差异。 相似文献

Recently arrived and settled Salvadoran refugees and Anglo-Canadians in London, Ontario were compared with respect to psychological distress, quality of life, and life satisfaction. A matched sample of 60 participants in each group completed a demographic questionnaire, the Brief Symptom Inventory, a shortened version of the Quality of Life Questionnaire, and the Satisfaction with Life Scale in either English or Spanish. Significant group differences were obtained on measures of quality of life and life satisfaction, but not of psychological distress. The results are discussed in relation to findings with other refugee groups. 相似文献

Interactions between sentence context and word frequencyinevent-related brainpotentials 总被引:2,自引:0,他引:2
Event-related brain potentials (ERPs) were recorded as subjects silently read a set of unrelated sentences. The ERP responses elicited by open-class words were sorted according to word frequency and the ordinal position of the eliciting word within its sentence. We observed a strong inverse correlation between sentence position and the amplitude of the N400 component of the ERP. In addition, we found that less frequent words were associated with larger N400s than were more frequent words, but only if the eliciting words occurred early in their respective sentences. We take this interaction between sentence position and word frequency as evidence that frequency does not play a mandatory role in word recognition, but can be superseded by the contextual constraint provided by a sentence. 相似文献

Recent visual evoked potential (VEP) studies suggest that during sustained voluntary attention, irrelevant or unattended visual stimuli may be filtered precortically. Testing of this hypothesis in humans requires knowledge of the origin of specific components of the VEP that are affected by selective attention. This study describes techniques and procedures for distinguishing between retinal and nonretinal components of VEPs recorded from electrodes placed strategically around the eyes and on the forehead. By visually stimulating one eye at a time while recording simultaneously from both, and by stimulating a given retinal area with the eyes fixated on the target at different angular deviations from the normal line of regard, components of the VEPs around the eyes can be distinguished as of retinal or nonretinal origin. The results are discussed in terms of volume conduction theory. 相似文献

Event-related potentials (ERPs) were recorded from subjects as they silently read 160 different seven-word sentences, presented one word at a time. Each sentence was in itself a natural, meaningful phrase. Substantial intersubject variability was observed in the ERP waveshapes following the words. More than half of the subjects generated P3 components to word stimuli, but those who did showed similar responses to repeated control presentations of a single word. In addition, it was found that all but the first word in the sentence elicited an ERP with a significant left-greater-than-right asymmetry in the late positivity over temporo-parietal regions. The ERPs to the last words were associated with more late positivity than those to the preceding words. One quarter of the sentences, at random, ended with a word printed in a typeface that was different from that of the preceding words. This infrequent change in typeface elicited a complex ERP having three consistent late positive components. 相似文献

Amyotrophic Lateral Sclerosis is a neurodegenerative disorder characterized primarily by motor network disruption. Extra-motor manifestations including executive functions, social cognition, and behavioral changes are now well recognized as important features of ALS, and are associated with frontotemporal and frontostriatal network disruption. However, the presence and characterization of language changes has received less attention. This systematic review characterizes the profile of reported language dysfunction in ALS. PRISMA guidelines were implemented to carry out and report the review. Current evidence suggests that areas of neuroanatomical disruption in ALS spread to language centers such as posterior, inferior frontal and superior temporal areas leading to deficits in word retrieval, syntactic and grammatical processing, and spelling. However, the majority of studies of language in ALS have been limited by the recruitment of small clinic-based prevalent samples and important questions remain regarding the incidence and progression of language impairment in ALS. Further studies from population-based incident cohorts will help to determine the range of language deficits in ALS, and how these relate to previously defined executive and behavioral sub-phenotypes. 相似文献

This document presents the Bonn PRINTEGER Consensus Statement: Working with Research Integrity—Guidance for research performing organisations. The aim of the statement is to complement existing instruments by focusing specifically on institutional responsibilities for strengthening integrity. It takes into account the daily challenges and organisational contexts of most researchers. The statement intends to make research integrity challenges recognisable from the work-floor perspective, providing concrete advice on organisational measures to strengthen integrity. The statement, which was concluded February 7th 2018, provides guidance on the following key issues:
