Hemispheric asymmetries for temporal information processing: transient detection versus sustained monitoring

This study investigated functional differences in the processing of visual temporal information between the left and right hemispheres (LH and RH). Participants indicated whether or not a checkerboard pattern contained a temporal gap lasting between 10 and 40 ms. When the stimulus contained a temporal signal (i.e. a gap), responses were more accurate for the right visual field-left hemisphere (RVF-LH) than for the left visual field-right hemisphere (LVF-RH). This RVF-LH advantage was larger for the shorter gap durations (Experiments 1 and 2), suggesting that the LH has finer temporal resolution than the RH, and is efficient for transient detection. In contrast, for noise trials (i.e. trial without temporal signals), there was a LVF-RH advantage. This LVF-RH advantage was observed when the entire stimulus duration was long (240 ms, Experiment 1), but was eliminated when the duration was short (120 ms, Experiment 2). In Experiment 3, where the gap was placed toward the end of the stimulus presentation, a LVF-RH advantage was found for noise trials whereas the RVF-LH advantage was eliminated for signal trials. It is likely that participants needed to monitor the stimulus for a longer period of time when the gap was absent (i.e. noise trials) or was placed toward the end of the presentation. The RH may therefore be more efficient in the sustained monitoring of visual temporal information whereas the LH is more efficient for transient detection.

幽门螺杆菌感染治疗新进展

在中国幽门螺杆茵(Helicobacter pybri,Hp)有非常高的感染率,国人感染率约55%,所以Hp感染处理中的临床问题是目前Hp研究领域中的重点课题,Hp感染治疗中的重要问题主要包括以下几方面:(1)哪些病人应该治疗?(治疗适应证问题);(2)如何治疗?(治疗方案问题);(3)如何避免或克服Hp对抗生素的耐药性问题?Hp对抗生素的耐药是Hp根除失败的主要原因,所以本文还要重点讨论Hp对抗生素的耐药牲,Hp根除失败的补救治疗及其治疗研究进展.

Elements of analytic style: Bion's clinical seminars

The author finds that the idea of analytic style better describes significant aspects of the way he practices psychoanalysis than does the notion of analytic technique. The latter is comprised to a large extent of principles of practice developed by previous generations of analysts. By contrast, the concept of analytic style, though it presupposes the analyst's thorough knowledge of analytic theory and technique, emphasizes (1) the analyst's use of his unique personality as reflected in his individual ways of thinking, listening, and speaking, his own particular use of metaphor, humor, irony, and so on; (2) the analyst's drawing on his personal experience, for example, as an analyst, an analysand, a parent, a child, a spouse, a teacher, and a student; (3) the analyst's capacity to think in a way that draws on, but is independent of, the ideas of his colleagues, his teachers, his analyst, and his analytic ancestors; and (4) the responsibility of the analyst to invent psychoanalysis freshly for each patient. Close readings of three of Bion's 'Clinical seminars' are presented in order to articulate some of the elements of Bion's analytic style. Bion's style is not presented as a model for others to emulate or, worse yet, imitate; rather, it is described in an effort to help the reader consider from a different vantage point (provided by the concept of analytic style) the way in which he, the reader, practices psychoanalysis.     

对解释伪忽视机制的两种理论的初步检验

以视野因素对伪忽视的影响为切人点来考察注意的右半球优势理论与表征的空间变形理论对伪忽视机制的解释。使用灰度标尺任务和三视野速示迫选的实验方法研究视野和操作用手因素对伪忽视的影响。结果显示,只有将两种理论结合起来才能对伪忽视机制作出更好的解释。     

移动窗口条件下不同工作记忆者阅读差异的眼动研究

采用EyelinkⅡ眼动仪为工具,考察在移动窗口条件下不同工作记忆容量读者的阅读差异。实验为5（窗口大小：1个字、3个字、5个字、7个字、4×25个字）×2（工作记忆容量：高、低）混合设计。结果表明：随着窗口大小的增加,阅读时间、注视次数、眼跳次数显著减少,阅读速度显著加快,眼跳幅度显著增加。与低工作记忆容量被试相比,高工作记忆容量被试能够更好地整合文章信息,进行更有效的阅读。
