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.     

Teaching critical psychology of ‘race’ issues: problems in promoting anti‐racist practice

The aim of this paper is to illustrate the difficulties faced by teachers of issues related to ‘race’ and racism in psychology when trying to develop anti‐racist practice in their teaching. I argue that the promotion of anti‐racist practice can be impeded by the institutionalised cultures of some psychology departments and that such cultures have developed out of an over‐reliance on positivist ideas. Positivism obscures the fact that knowledge is constructed from positions of power and privilege, which in turn obscures the social and ideological construction of ‘race’. This is clearly a problem when trying to develop anti‐racist practice in teaching. It also leads to fixed ideas about what should be included in teaching content and what can be considered as good pedagogical practice, where notions of ‘balance’ and ‘neutrality’ are advocated, effectively overriding arguments for understanding the dynamics of knowledge production. It also obscures the power and privilege associated with workings of ‘whiteness’. I illustrate this by presenting examples from my own experiences of teaching ‘race’ issues on undergraduate degree courses. I conclude with suggestions for developing anti‐racist teaching by proposing a collective reflexive approach to changing institutional cultures that are currently at odds with anti‐racist practice. I also invite further discussion and suggestions on how best to achieve such collective conscientisation. Copyright © 2007 John Wiley & Sons, Ltd.     

An analysis of autobiographical tools in written reflection: implications for teaching critical thinking and goal-setting

This paper analyzes the results of an 18 month study of a variety of participants involved in written reflection on their learning, both in classes at two universities in the Southern US or in voluntary focus groups. The purpose of the study was to analyze the effects of including autobiographical tools in written reflection. Participants used three tools from the genre of autobiography as they reflected on their learning inside either course content, internship experiences, experiential learning, or goal-setting. Over 500 samples were gathered, offering a large data set for analysis of what kinds of best practice produce quality reflective writing. Through analysis of the data and student surveys and interviews, results show increased attention to critical thinking and metacognition; expressed flexibility, adaptability, and ability to handle ambiguity; and value in connection to others/empathy-building as a result of incorporating autobiographical tools in reflective prompts. The study indicated that reflections using the same autobiographical tool over the course of several sessions seemed to produce deeper levels of reflection and more engagement with the autobiographical tool. Of the three autobiographical tools used in the study, the tool that seemed most helpful to participants was reflection as storytelling that revealed aspects of the self.

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.     

Disturbing Politics: Neo‐Paulinism and the Scrambling of Religious and Secular Identities

Abstract : One of the most remarkable characteristics of recent cultural theory is its obsession with the early Christian apostle Paul. With this interest in Paul as contemporary cultural theory, a panoply of modern identities find themselves obsolesced, scrambled, or otherwise useless. This essay attempts to find new points of orientation within those scrambled identities that have appeared with this new Paul, and the essay does so by exploring the idea that we are now repeating a Pauline moment of kairos, that apocalyptic moment in which meaningful transformation of the world may occur.     

Young people's perceptions and experiences of leaving high school early: an exploration

Research suggests it is important for students to feel a sense of belonging to their school. Students who do not belong at school often attempt to satisfy this need through membership in antisocial groups, or they drop out from school altogether. The current study explored the perceptions and experiences of the school context held by young people who have left school early. Twelve young people aged 16–19 years were interviewed on their experiences of school and their wellbeing as a result of leaving school early. Constructionist grounded theory methodology formed the basis of the data analysis. The early leaving process was identified as having three phases; exclusion from school, the transition into workforce and the ‘now’ phase. The results identified factors in the school context that contributed to early student withdrawal. Furthermore, the research has implications for creating a ‘normative narrative’ (Rappaport, 2000 ) in relation to early school leavers. Copyright © 2007 John Wiley & Sons, Ltd.
