Using discriminant function analyses on survey data collected from 457 students in 29 education administration programs across the United States, the authors inquired into whether men and women decide to enter and possibly leave education administration for different reasons. There were statistically significant functions separating men and women in their reasons for entering and leaving education administration. Implications of the findings are discussed. 相似文献

An important but often neglected aspect of attention is how changes in the attentional spotlight size impact perception. The zoom-lens model predicts that a small (“focal”) attentional spotlight enhances all aspects of perception relative to a larger (“diffuse” spotlight). However, based on the physiological properties of the two major classes of visual cells (magnocellular and parvocellular neurons) we predicted trade-offs in spatial and temporal acuity as a function of spotlight size. Contrary to both of these accounts, however, across two experiments we found that attentional spotlight size affected spatial acuity, such that spatial acuity was enhanced for a focal relative to a diffuse spotlight, whereas the same modulations in spotlight size had no impact on temporal acuity. This likely reflects the function of attention: to induce the high spatial resolution of the fovea in periphery, where spatial resolution is poor but temporal resolution is good. It is adaptive, therefore, for the attentional spotlight to enhance spatial acuity, whereas enhancing temporal acuity does not confer the same benefit. 相似文献

独体汉字的字形相似性研究 总被引:6,自引:2,他引:4
本文以速示呈现方式获得了一系列独体汉字和字符的混淆矩阵。用Luce(1963)的选择模型特混淆矩阵分解为对称的相似矩阵和反应倾向矢量。基于相似矩阵,以聚类分析和多维量表法探索了汉字和字符的视觉特征及其表征形式,为揭示汉字视觉特征的几何特性和潜在结构,在研究方法上作了有意义的偿试、此外,本研究的结果支持了作者(1995)关于在含“十”或“口”的独体汉字中,“十”与“口”是该类汉字的突出视觉特征的结论。 相似文献

An Internet-based instructional module was developed using Netscape 2.0 as the graphical interface. The content concerned Bayesian probabilities and expected outcomes associated with the use of urine drug screens. JavaScript enabled interactive calculations of outcome probabilities given a selected set of parameters, and AppleScript and Claris Filemaker Pro monitored and recorded student activity and progress. The module was initially used in an undergraduate class on alcohol and drugs and subsequently evaluated on a sample of undergraduates. Student response was favorable, and student learning assessed by performance on an exam was good. Students who described themselves as not computer literate did not particularly enjoy the experience, although they performed as well as others on the test. The success of this demonstration project has led to more ambitious implementations, particularly those that monitor student activities and provide intelligent feedback. 相似文献

不同年级学生读课文时眼睛注视方式的研究 总被引:10,自引:1,他引:9
采用3200型眼动记录仪,以小学三年级、小学五年级、初中一年级、高中一年级和大学各30名视力正常的学生为被试,记录了他们在有一定阅读任务要求下的眼睛注视方式。结果发现:阅读速度随年级升高而加快,且小学五年级组和初中一年级组、高中一年级组和大学生组之间差异显著;在读课文的过程中,各年级学生使用两种类型的国视和四种注视课文的方式;回视次数随年级升高而减少,且句间回视次数显著多于句内回视次数;各年级学生读课文时以使用直接和往复注视方式为主,以使用问题和不规则方式为辅。 相似文献
