SEVERE CLASSROOM BEHAVIOR PROBLEMS: TEACHERS OR COUNSELLORS

This experiment was designed to determine the relative effectiveness of teacher and counselling approaches in the reduction of disruptive or inappropriate classroom behavior. Inappropriate classroom behavior frequencies of 12 academically low achieving, seventh-grade, black male students, with a reported high rate of inappropriate classroom behavior, were recorded. Three groups, with nearly equal mean inappropriate behaviors, were randomly assigned to one of three treatment conditions: behavioral counselling, client-centered counselling, or no counselling. Each counselling group received fifteen 30-minute counselling sessions, at a rate of two to three times a week. In addition to counselling, all students subsequently received teacher approval within the classroom. Results indicated that the teacher was able to reduce inappropriate behavior more than any counselling group. There were also indications that behavioral counselling, but not client-centered counselling, was moderately helpful in reducing inappropriate classroom behavior.     

妄想型与非妄想型精神分裂症唤醒水平(皮肤电反应)的初步探讨

问 题 机体如果连续处于高唤醒水平,就会出现中枢神经系统兴奋-抑制关系紊乱的现象。一般的后果是抑制机制受损害而产生中枢性调节障碍(Malmo 1959)。在行为上,唤醒水平表现为机体作出反应、准备行动的能量动员水平。对精神病人唤醒水平的研究     

The effects of delayed and displaced visual feedback on motor control

Developments in television technology have made possible new approaches to the study of the role of visual feedback in motor control. In two experiments using a special videodisc recording and playback system, the effects of delaying for 66 msec a subject's view of his own hand during a target-directed movement was investigated. The observed effects of such visually delayed feedback compared to spatially distorted feedback produced by prisms led to three major conclusions: (a) despite the behavioral similarity (overshooting) induced by the two kinds of altered feedback, the role of each in the visual-motor control loop is different; (b) adaptation to and the after effect of the two kinds of altered feedback are based on different control mechanisms (c) the processing and use of visual information in hand control requires less time than previous experiments have indicated.     

初中代数“有理数”程序教学实验研究

本研究对程序教学与传统教学的效果作了对比。研究表明,程序教学可以缩短学习时间、提高学习效果、激发学习动机,有助于自学能力的培养。如果程序教材能够符合学生的认识规律,在教材中尽量增加启发因素,那么程序教学对于思惟能力的培养也可以起到积极的作用。     

文昌鱼的光动反应

文昌鱼的中枢神经系统早在上个世纪就受到神经解剖学家们的注意。这是因为它代表着动物演化上的一个很典型的阶段。在这个阶段,动物身体的背侧开始有了神经管。这个神经管在外形上很象脊椎动物胚胎初期形成的神经管,其内部的神经组织也较简单。此外,正如神经管初成阶段的脊椎动物胚胎一样,文昌鱼还不具备发育的和特异     

The Stroop congruency effect is more observable under a speed strategy than an accuracy strategy

Naming the ink color of an incongruent color word (e.g., RED printed in green) usually takes longer than naming the ink color of a color bar. However, when the ink matches the word (e.g., RED printed in red), naming tends to be faster. These phenomena are known as the STroop interference effect and the Stroop congruency effect, respectively. Although the interference effect has been robust and reliable across studies, the congruency effect tends to be elusive. It was hypothesized that this variation in outcomes might be related to subjects' response strategy. The experiment conducted to test this hypothesis induced either a speed or an accuracy strategy in two separate groups of subjects. Significant interference effects were found for both groups and the magnitudes did not differ. At the same time, the congruency effect was observed in the speed group but not in the accuracy group. These results suggest that researchers who wish to observe and study the Stroop congruency and interference effects should place special emphasis on speed. Implications of the study for a model of the Stroop effect are also discussed.

平行斜线诱导的垂直错觉之规律及原因初探

此实验测定了20个大学生和青年工人的垂直错觉。错觉模式的诱导部分为一组平行斜线,测试部分为差不多互相垂直的竖直线和水平线。在平行斜线诱导下,被试产生了把测试部分看成垂直的错觉。错觉量的大小与诱导线的倾斜角度有关。把此错觉模式的诱导部分与测试部分分开,以实体镜观察时(一个眼各看一部分,两眼同时观察)则没有发生错觉,说明此错觉最初可能发生于视网膜上。此错觉可用侧抑制理论来解释。     

全球地域化:基督宗教在华传播史的一种诠释——对章开沅"传播与植根"观念的解读

章开沅自20世纪80年代中期涉足中国基督宗教史研究领域.他通过深入考察基督宗教在中国传播的历史进程,精辟阐释中西文化的巨大差异,透彻解析中外基督徒有识之士的经典著述,站在跨文化对话的高度,对中国基督宗教史予以"全球地域化"解读.章开沅认为,只有构筑中国本土化的世界观与价值观,才是基督宗教在华"传播与植根"的必由之路.
