影响深度辨别的因素,如目标物的长度、寬度、移动速度、垂直距离、背景照明以及不同的地表面等等,前人已作过許多研究。但是,这些研究都是观察者与目标物均处于正直的状态下进行的。至于观察者或目标物处于不同角度的傾斜状态下,对深度辨别有何影响,在文献中还較罕見。沃克(R. Y. Walker)曾作过这类研究,他以豪瓦德-多尔曼  相似文献

Checkerboards contain fundamental two-dimensional Fourier components oriented 45° from the edges of individual checks. Previous studies have shown that contingent color aftereffects following adaptation to chromatic checkerboard stimuli were associated with the fundamental components rather than the edges, In the present experiments, we measured contingent color aftereffects, using the method of constant stimuli, after subjects adapted to unfiltered checkerboards and checkerboards with the fundamental Fourier components removed. The adaptation stimuli were magenta (or green) squares and green (or magenta) diamonds; the test stimuli were vertical or oblique sine-wave gratings with different saturations, After adaptation to unfiltered checkerboards, aftereffects contingent on the fundamental components were obtained. In contrast, after adaptation to filtered stimuli, aftereffects of smaller magnitude were found to be aligned with the edges. The data support the previous findings of spatial-frequency-contingent color after-effects with checkerboard adaptation stimuli and indicate that the aftereffects can be associated with edges if the fundamental components of adaptation stimuli are removed by spatial filtering. We reexamined the possibility of color aftereffects induced by imagery of checkerboards. Contrary to the previous reports, no significant aftereffects were obtained.  相似文献

This paper addresses the issue of cultural adaptations and diffusion for managerial strategies in host societies to which work enterprises are not indigenous in terms of their capital and management or either. With illustrations drawn from a series of case-studies of work organisations in Hong Kong managed respectively by Chinese, British and Japanese capital, there was an appearance of support for the thesis of ‘cultural’ determinism and its implications for strategical adaptations in work organisations. The implication was drawn that the Oriental nexus of altruism, trust and subtlety could be rooted in the more laudible and perhaps global influence of Confucianism. Some subsequent issues are raised. First, the problem of cultural adaptation is not specific to multinationals or foreign firms visiting from outside but also applies where the management and their ethic background are not indigenous. The other issue is the extent of cultural adaptation within work organisations, as determined by the degree of affinity with a common mother culture. The paper suggests that a common denominating mother culture can serve a strategical starting point to bring about intra-organisational and organisation-society link and harmony.  相似文献

Simple forms, such as a square and a circle, can be symbolic; for example, a square can be deemed to behard and a circle to besoft. The relation between form symbolism and the comprehension of metaphors and analogies was studied in three experiments. Subjects were asked to rate matches between terms such assoft andhard andcircle andsquare as symbols (Experiment 1), metaphors (Experiment 2), and analogies (Experiment 3). The results show that a highly rated symbolic relation could be a poorly rated metaphorical relation. Ratings of analogies were similar to ratings of symbols. We argue that apt metaphors, analogies, and symbolic forms claim that the vehicle and the topic of the comparisons have common features, but that metaphoric representation entails more common features than does either symbolism or analogy, because metaphor requires that the vehicle be an especially apt example of a superordinate class. Thus, metaphor is a particularly strong claim about common features shared by the topic and the vehicle.  相似文献

State and trait-regulation models were compared in 315 eleventh-graders using simultaneous confirmatory factor analysis. Each of the first-, second-, and third-order factor models was found to describe the data from both state and trait measures well. In both state and trait self-regulation models, the third-order factor, self-regulation, is composed of metacognition and effort, and the second-order factor, metacognition, is composed of awareness, cognitive strategy, planning, and self-checking. Findings of invariant factor loadings and factor correlations across state and trait measures indicate that the state and trait self-regulatory factor structures are similar. Unlike the state-trait distinctions found in affective personality domain, clear state-trait distinction was not found in this cognitive domain. In both measures, students who engaged more frequently in metacognitive activities and effort use in their mathematical problem solving performed better than those who did not.  相似文献

Strong misalignment effects are found in three-dimensional (3-D) versions of Poggendorff displays viewed binocularly. The components of the standard 2-D Poggendorff figure—the parallels and the oblique segments—were presented in 3-D depth as a flat rectangular object with occluding edges and an oblique line situated behind the object. Three experiments investigated the misalignment effects under three different observation instructions: Subjects were told to look at the oblique (Experiment 1), at the rectangle (Experiment 2), or at the background (Experiment 3). Experiments 1 and 2 examined the effects on judgments of alignment of varying the distance in depth that separates the oblique from the rectangle. Experiment 3 examined the effects of varying the distance between the fixated background and the 3-D Poggendorff figure. Both standard and reversed misalignment effects were obtained. When the viewing condition produces crossed disparity for the oblique, perceived misalignment occurs in the usual Poggendorff direction, but it is reversed with uncrossed disparity. Moreover, the amount of misalignment is related to the amount of disparity, and it can be much stronger than is usual in the 2-D versions of the Poggendorff. The misalignment effects can be explained by binocular integration to produce a single cyclopean image.  相似文献

采用感知教师支持、学习投入、学业自我效能感和成就目标定向问卷对498名高中生进行问卷调查,探讨感知教师支持对学习投入的影响,以及学业自我效能感和成就目标定向的链式中介效应。结果显示:(1)感知教师支持能通过学业自我效能感间接预测高中生学习投入,感知教师支持可以通过掌握趋近、表现趋近、表现回避间接预测高中生学习投入;(2)学业自我效能感→掌握趋近、学业自我效能感→表现趋近、学业自我效能感→表现回避三者分别在感知教师支持与学习投入之间起链式中介作用,学业自我效能感→掌握回避的中介效应则不显著。上述结果表明,感知教师支持不仅能分别通过学业自我效能感、掌握趋近、表现趋近、表现回避预测高中生学习投入,还能通过学业自我效能感和成就目标定向的链式中介作用间接预测高中生学习投入。  相似文献

对湖北省两所中学3219名初一至初三年级学生进行问卷调查,建立结构方程模型考察父母粗暴养育、核心自我评价、友谊质量和青少年智能手机成瘾的关系。结果发现:(1)核心自我评价在父母粗暴养育和青少年智能手机成瘾之间起部分中介作用,即父母粗暴养育既对青少年智能手机成瘾产生直接影响,也通过核心自我评价对青少年智能手机成瘾产生间接影响;(2)父母粗暴养育和核心自我评价的关系(中介作用的前半段路径)受到友谊质量的调节,即在高友谊质量和低友谊质量条件下,随着粗暴养育程度的增加,青少年核心自我评价均显著下降,但在高友谊质量的条件下,下降的程度更高。研究结果有助于揭示父母粗暴养育对青少年智能手机成瘾的影响及其作用机制,为预防和干预青少年智能手机成瘾带来一些重要的启示。  相似文献

A study of the appearance-reality distinction in American 3- to 5-year-olds was replicated with Chinese 3- to 5-year-olds. The error patterns, age changes, and absolute levels of performance were similar in the two samples. It was speculated that the acquisition of this distinction may be a universal, possibly age-linked development that is probably fueled by experiences with appearance-reality discrepancies that are available in all cultures.  相似文献

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。  相似文献
