Neuropsychological classification and treatment of dyslexia.     

D J Bakker 《Journal of learning disabilities》1992,25(2):102-109

Evidence shows that initial and advanced learning to read are predominantly mediated by the right and left cerebral hemispheres, respectively. Premature reliance on left-hemispheric reading strategies may result in L-type dyslexia, characterized by hurried and inaccurate reading. P-type dyslexia, characterized by a slow and fragmented style of reading, may result from the inability to shift from the predominant generation of right-hemispheric reading strategies to the predominant generation of left-hemispheric reading strategies. Results of investigations concerning the validity of the L/P-typology are discussed, as are the reading effects of hemisphere-specific and hemisphere-alluding stimulation in children with L- and P-type dyslexia.  相似文献   

East Meets West in Assessment Development: Western Technical Assistance to Eastern Needs. Part III. Reform of an Examination System: Shoulder to Shoulder in the Polish SMART Project     

Annemarie de Knecht-van Eekelen  Steven Bakker  Gerben van  Lent 《Educational Measurement》2001,20(3):33-35

This is Part III of a three part series describing the consultancy and training demands that are encountered in technical assistance projects in Central and Eastern Europe. Part I dealt with strategic issues for a successful delivery of "Western Technical Assistance to Eastern Needs." Part II highlighted project management and co-operation aspects in delivering support to the Romanian Assessment and Examination Service. In this part, we address training of Polish subject experts who were preparing to take on responsibility for a decentralized and strongly innovative final exam, the Matura.  相似文献

Language proficiency and lateral position in the classroom     

Dirk J. Bakker Ph.D.  Raymond Van Rijnsoever Ph.D. 《Annals of dyslexia》1977,27(1):37-53

This paper not only makes a contribution to the mosaic of scientific knowledge of the brain and nervous system, but suggests implications of practical value. Observant, experienced teachers know empirically that some youngsters learn best, and perhaps only, when seated front-center, right before the teacher’s desk. Such children need to have the eye contact, or to be in quick arm’s reach, or to have distractions screened out. Drs. Bakker and Van Rijnsoever give evidence here that, for many children, taking in and remembering the message is dependent on their physical placement to catch most effectively the stream of sound. This is important to consider in the popular open classroom. Although many children can adapt readily to less-than-perfect physical learning conditions, for some we must “re-invent the wall,” not to climb, but to provide a place to call “home.” The theoretical re-inforcement presented in this paper proves that such boundaries can also provide source and direction for sound as part of some children’s currently needed sensory security and enhance the efficiency of their auditory intake.

Cognitive brain potentials in kindergarten children with subtyped risks of reading retardation     

Bakker DJ  Van Strien JW  Licht R  Smit-Glaudé SW 《Annals of dyslexia》2007,57(1):99-111

Cognition-related brain responses to meaningful and meaningless figures were registered in 5-year-old kindergarten children who either had been subtyped as being at-risk of developing an L- or P-type dyslexia (LAL versus LAP) or who were not at-risk. While identifying, naming, or categorizing pictures, event-related potentials (ERP) were registered. Three cognition-related components were found: the N460, the P780, and the Slow Wave (SW). LAP-children produced weak N460 activity across tasks, whereas LAL children, and to a lesser degree, non-risk children produced robust task-dependent activity. This finding may indicate that LAP-children lack semantic input while processing the figures. P780 latencies to frequently occurring figures were found hemisphere-dependent: LAP-children showed longer latencies in the right than in the left hemisphere, whereas the distribution was reversed in the LAL and non-risk children. It was also found that the right hemisphere is generally responsible for a lion's share of the processing of figures and therefore it seems that the right hemisphere of LAP-children invests ample time in doing so. Whereas LAP-children showed largest SW amplitude differences between frequent and infrequent stimuli at posterior locations, LAL children did so at frontal locations. Assuming that the SW represents working-memory processes, it may be that working-memory in LAP-children deals with figure-relevant visual-spatial information and with figure-derived concepts in LAL children. Overall, the findings suggest that LAL and LAP represent two different groups of kindergartners at risk of dyslexia and that these differences, to some degree, fit with the presumed etiology of L- and P-type dyslexia.  相似文献   

The influence of anxiety on visual attention in climbing   总被引：2，自引：0，他引：2  

Nieuwenhuys A  Pijpers JR  Oudejans RR  Bakker FC 《运动与训练心理学杂志》2008,30(2):171-185

The object of the current study was to investigate anxiety-induced changes in movement and gaze behavior in novices on a climbing wall. Identical traverses were situated at high and low levels on a climbing wall to manipulate anxiety. In line with earlier studies, climbing times and movement times increased under anxiety. These changes were accompanied by similar changes in total and average fixation duration and the number of fixations, which were primarily aimed at the holds used for climbing. In combination with these findings, a decrease in search rate provided evidence for a decrease in processing efficiency as anxiety increased.  相似文献   

Helsen, Gilis and Weston (2006) err in testing the optical error hypothesis     

Oudejans RR  Bakker FC  Beek PJ 《Journal of sports sciences》2007,25(9):987-990

In this commentary, we react to the recent study by Helsen, Gilis and Weston (2006) on judging offside in football. Helsen et al. claim that their data falsify the optical error hypothesis presented by Oudejans et al. (2000). However, as we will elucidate here, they misinterpret this hypothesis and present a data set that is seriously flawed, and hence not suited to test it. Therefore, their conclusions regarding the optical error hypothesis are in error.  相似文献

Moral authorship of novice teachers in primary education     

Rob Gertsen  Harmen Schaap  Cok Bakker 《Teachers and Teaching》2017,23(5):570-582

This article focuses on moral authorship as an element of the professional development of novice teachers in the Netherlands. Moral authorship refers to the ability of teachers to observe, identify, verbalize and reflect on the moral aspects of their work in a proactive and dialogical manner. We elaborate on moral authorship by theoretically exploring six interdependent tasks of moral meaning making: moral commitment, awareness, orientation and positioning, moral performance and evaluation. Narratives of 19 novice teachers were analyzed to explore moral authorship in teachers’ talk. The results show the opportunities of moral authorship to support, navigate, and reinforce the professional development of novice teachers. This study suggests professional self-dialogs for enhancing the development of moral authorship.  相似文献   

Designing for communication at work: A case for technology-enhanced boundary objects     

Arthur Bakker  Phillip Kent Celia Hoyles  Richard Noss 《International Journal of Educational Research》2011,50(1):26-32

In this article we conceptualise the challenges of communication between a mortgage company and its customers in terms of crossing boundaries between communities. Through an ethnographic study we first address the question: what are the challenges of communication between sales agents and customers of a mortgage company around mathematical artefacts? Insight into these challenges formed the basis for an intervention in which we designed technology-enhanced boundary objects (TEBOs) that were reconfigurations of problematic symbolic artefacts. Secondly, we ask what the sales agents learned from the intervention. The data suggest that the intervention with the TEBOs helped employees to develop a better understanding of the mathematics behind the mortgages they sold, and to improve communication with their customers.  相似文献
