中学生物理学业情绪问卷的修订及调查研究

以青少年学业情绪问卷为基础,结合物理学科特点对问卷项目进行修改,修订中学生物理学业情绪问卷.以314名初二到高二学生为被试进行预测,通过验证性因素分析对问卷项目进行调整,最终问卷包括67个项目.经检验问卷的内部一致性信度、分半信度和效标效度符合测量学的要求.在此基础上,选用728名初二到高三学生为被试.结果发现:(1)总体来看,男生,尤其是来自重点中学的男生,其积极物理学业情绪要高于女生,而女生的消极物理学业情绪要高于男生;(2)重点中学的初中生的积极低唤醒物理学业情绪得分显著高于高中生,且重点中学的初中生的消极低唤醒物理学业情绪得分显著低于高中生,而普通中学则正好相反;(3)在物理学业情绪中,积极高唤醒和积极低唤醒的所有因子与物理学业成就皆呈显著正相关,而消极高唤醒(仅羞愧)和消极低唤醒(厌倦、无助、心烦-疲乏)与物理学业成就呈显著负相关.     

颈动脉病变的治疗现状

颈动脉病变尤其是颈动脉狭窄治疗上的分歧,颈动脉内膜切除术受欧美学者推崇,颈动脉支架成形技术受国内学者青睐,本文就近年来的文献复习发现颈动脉内膜切除术和颈动脉支架成形术各有相宜的适应证,各有优缺点,根据各自医院的设备条件、医师对颈动脉内膜切除术和颈动脉支架成形术熟悉程度来开展工作,对颈动脉狭窄治疗均有益处,存在的问题和困...     

大学生恋爱动机问卷的初步编制

目的:探讨大学生恋爱动机的结构并编制相应的测量工具。方法:运用文献法、开放式问卷和访谈法设计问卷,多次施测修改问卷,采用相关分析、探索性分析和验证性分析对问卷的信、效度进行检验。结果:大学生恋爱动机问卷包括功利性、面子性、性爱性,情感性、消遣性和婚姻性六个维度,累计贡献率57.459%,共27项;问卷的信度和效度均符合心理测量学的要求。结论:大学生恋爱动机问卷可作为测评大学生恋爱动机的工具。     

不同车速下司机对交通标志的辨认距离实验

本实验所得数据表明,不同车速下司机对同一标志的判读距离是不一样的,车速愈高,司机能判读标志的距离就愈短,同步行时相比,在车速提高到100公里/小时时,司机对标志的判读距离可减低35～45％。据我们的补充实验,这种现象的产生可能是由于司机在高速驾车情况下所产生的生理心理负荷造成的。     

Multidimensional scaling reveals two dimensions of thermal pain

The Individual Differences Scaling (INDSCAL) model of multidimensional scaling was used to explore the dimensions of thermal pain. The observers made 66 similarity judgments to all pairs of 12 different thermal stimulus intensities ranging from zero to noxious. Analysis of the data revealed a two-dimensional group stimulus space. The major dimension ordered the stimuli with respect to their intensity. This quantitative, strength-of-sensation dimension may be interpreted as indicating how weak or strong a stimulus feels, apart from any secondary qualities of warmth or pain. The second dimension was related to the qualitative aspects of the stimuli. This bipolar dimension contained two attributes: a pain attribute ranging from just detectable warmth to painful, and a warm-hot attribute running from just detectable warmth to hot. This study demonstrates the utility of the INDSCAL approach to the understanding of pain and offers a new technique for answering the age-old question concerning the number and qualities of the dimensions underlying the pain experience.     

Weakening the robustness of perspective: Evidence for a modified theory of compensation in picture perception

Viewed from the center of projection, a perspective picture presents the pictorial depth information of a scene. Knowing the center of projection, one can reconstruct the depicted scene. Assuming another viewpoint is the center of projection will cause one to reconstruct a transformed scene. Despite these transformations, we appreciate pictures from other viewpoints. The compensation hypothesis states that the visible picture surface allows observers to compensate for transformations by locating the center of projection and experiencing pictorial space from there. We show that observers neither completely compensate for nor experience transformations of space as geometry would predict. We propose a modified compensation hypothesis according to which different degrees of visibility of the picture surface invoke different degrees of compensation.
