The effect of anticipated achievement feedback on students' semantic processing as indicated by the N400 cloze effect

The present study examined the effects of anticipated achievement feedback on students' semantic processing on the neural level, using event-related brain potentials (ERPs). Participants (N = 79) anticipated either self-referential or normative achievement feedback regarding an announced upcoming test. Additionally, their performance expectations (low vs. no expectations) were orthogonally manipulated. Subsequently, students' on-line semantic processing was assessed by measuring the N400 cloze effect, a component in the EEG signal of which the amplitude is associated with semantic processing. Within the low performance-expectation condition, no effect of anticipated feedback on semantic processing was found. Within the no-performance-expectation condition, participants anticipating self-referential feedback showed a more widely distributed N400 cloze effect than participants anticipating normative feedback. The results confirmed the hypothesis that the mere expectation of a particular type of feedback can affect students' semantic processes.     

Research-based teacher education? Exploring the meaning potentials of Swedish teacher education

In this article, we explore the meaning potentials of teacher education in terms of the significance of a research-based approach and the different pedagogic identities that such an approach implies. The study’s aim is to examine the important factors for education to be considered research-based and to identify and analyse the research base of teacher education in Sweden. The results from the analysis of a large number of course documents and from a survey administered to teachers and students in four teacher education programmes indicate that the emerging potential meaning is that teacher education is generally a strongly framed professional education with a relatively weak and adapted research base. The analysis of the classification and framing of disciplinary content and pedagogy in the Swedish teacher education curriculum points at different pedagogic identities emerging from the different meaning potentials that are made available to the students. We argue that a thorough understanding of research-based teacher education needs to be grounded in both course content and its research base as well as other possible pedagogical aspects of research-based education; the education as a whole must be included in the concept of research-based education.     

运动对事件相关电位的影响

事件相关电位（ERP）作为可以反映大脑高级思维活动的一种客观方法在研究认知功能中得到广泛的应用,而作为其内源形成分的P300是ERP中最典型、最常用的成分和认知过程密切相关,被视为“窥视”心理活动的一个窗口,并认为它是脑研究的一种新型手段。目前人们研究体育活动对认知功能的影响大多通过研究运动对P300的影响来实现。本文对学者关于此方面的研究做一个总结。

Time-frequency analysis of EEG signals evoked by voluntary,stimulated and imaginary motions

In order to investigate the characteristics of sensorimotor cortex during motor execution(ME), voluntary, stimulated and imaginary finger flexions were performed by ten volunteer subjects. Electroencephalogram(EEG) data were recorded according to the modified 10-20 International EEG System. The patterns were compared by the analysis of the motion-evoked EEG signals focusing on the contralateral(C3) and ipsilateral(C4) channels for hemispheric differences. The EEG energy distributions at alpha(8—13 Hz), beta(14—30 Hz) and gamma(30—50 Hz) bands were computed by wavelet transform(WT) and compared by the analysis of variance(ANOVA). The timefrequency(TF) analysis indicated that there existed a contralateral dominance of alpha post-movement event-related synchronization(ERS) pattern during the voluntary task, and that the energy of alpha band increased in the ipsilateral area during the stimulated(median nerve of wrist) task. Besides, the contralateral alpha and beta event-related desynchronization(ERD) patterns were observed in both stimulated and imaginary tasks. Another significant difference was found in the mean power values of gamma band(p0.01)between the imaginary and other tasks. The results show that significant hemispheric differences such as alpha and beta band EEG energy distributions and TF changing phenomena(ERS/ERD) were found between C3 and C4 areas during all of the three patterns. The largest energy distribution was always at the alpha band for each task.
