Misalignment effects in 3-D versions of Poggendorff displays

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.     

影响常用汉字认知速度的因素：低频冲突字、联绵词尾字和高频多音字的认和特点

以汉族大学生为被试对低频冲突字、联绵词尾字和高频多音字的认知特性进行了探索。结果发现：主要部件读音与整字读音相冲突的低频字命名反应中具有延时效应（即命名反应时延长或反应错误率升高）;对联绵词尾字和多音字的命名反应同样出现延时效应。研究支持汉字认知的多因素影响论。     

A comparison between the development of the appearance-reality distinction in the People's Republic of China and the United States

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.

双目光学测距仪器光轴不平行度范围的实验研究

目前,我国的双目光学测距仪器光轴不平行度公差大致有以下几组: 垂直发散:±15′±20′±20′±27′ 水平发散:60′60′60′60′ 水平会聚:20′20′30′36′上述数据基本上是沿袭国外有关数据。美苏两国这方面的数据大致为:     

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。     

关于不舒适眩光的初步研究

根据对视觉功能影响的观点,眩光是视场内由于亮度不均匀,或由于亮度变化的幅度太大,或由于空间和时间上存在极端对比,以致引起不舒适,甚至视力降低或失能,在人们的心理、生理上产生影响。人们在长时间内处于过亮的光源下而发生不舒适感的眩光称
