問題識記时若有两种或多种感觉通道同时活动,可能彼此助长,也可能相互干扰。这对于了解識記时神經中枢各部分的活动与相互影响可能有一定的启发意义。视、听两种感觉通道在学习时最常应用,两种感觉通道可以同时或先后接受同一的刺激物,也可接受不同的刺激物。以往关于比較視、听材料識記效果的研究較多,結果指出,两种感觉材料的識記效果一般难分高低,主要决定于材料的性貭与被試的經驗等条件。 相似文献

問題 深入地探討体育館內观众席的视觉效果問題,是保証观众“看得好”的首要因素,是合理分布观众席、决定比賽厅平面形式(如圓形、椭圓形、方形、矩形等)的必备前提。决定观众席视觉效果的两大因素是观察距离及观察方位。关于这两个問題,国內外先后都进行过研究,但距离、方位与观众席分区方法的关系等問題,一般多局限在理論方面的討論,不能完全符合于实际情况。要对这些問題进行更深入的探討,必需进行视知觉心理学方面的实驗和研究,非仅靠建筑学知識所能解决,本研究卽试图通过知觉心理学的研究方法,对体育館比賽厅观众席距場地距离与視觉辨认的关系进行一些探索。 相似文献

朗讀与默讀是閱讀的两种形式,在語文教学中有效地运用朗讀与默讀是提高閱讀效率的重要条件。据有些中学語文教师反映,初一学生只习慣于朗读,而不善于默讀。不論什么学科的課文,什么性貭的文章,一概誦讀。这些教师认为,朗读固有利于熟記成誦,但 相似文献

The aim of this study is to explore reasons for and against prenatal testing and termination for a range of conditions in
women from two different ethnic backgrounds. A total of 19 Pakistani and European women in West Yorkshire, UK, who either
had a child with a genetic condition or had terminated a pregnancy for one, completed a questionnaire about their attitudes
regarding prenatal testing and termination for 30 different fetal conditions and were interviewed about their reasons for
their responses. There were more similarities than differences between the Pakistani and European white women. The most important
factor in most women’s decisions about termination of pregnancy was their perception of the quality of the life of a child
with the genetic condition, in particular, whether the child would be “suffering.” This was described as either physical suffering,
as a result of medical treatment, or as emotional suffering, as a result of psychological and/or social factors. These findings
highlight the need for detailed information about the potential quality of life for the child and the child’s family to enable
parents to make informed choices, particularly the extent to which the child is likely to suffer, the nature of such potential
“suffering” and the extent to which the child could lead a “normal” life. The findings also challenge stereotypes about cultural
differences in attitudes about termination of pregnancy. 相似文献
