The Road-Map Test (RMT) is a popular neurological assessment of left-right orientation, using a simplified road map. Inspired
by the RMT, we developed a new computerized navigation test, the Random Walker Test (RWT), for further quantitative assessment
of left-right orientation ability. RWT provides verbal or nonverbal instructions for the direction (left, right, or front)
in which to proceed, and participants must judge the spatially correct direction. Perspectives rotate by 90° during navigation.
Verbal judgments demand verbal-to-spatial mapping of left/right/front and, if necessary, egocentric perspective rotation.
Using the RWT, we evaluated the left-right orientation of normal male participants. The RWT reliably recorded the response
times and error rates for participant performance and also revealed egocentric perspective rotation as an unreliable mental
process with large intra- and interpersonal variability. These results indicate that the RWT may be useful in investigating
left-right orientation and/or egocentric perspective rotation in both normal participants and neuropathological patients. 相似文献

经验取样法是一种有效的密集纵向研究数据收集方法。该方法的优点正逐渐被广大研究者所认同,国外运用经验取样法取得的研究成果越来越多,而国内学者对经验取样法的研究尚处于探索阶段,运用此方法的实证研究更是凤毛麟角。通过对《应用心理学期刊》(Journal of Applied Psychology)最近5年(2010~2014年)发表的26篇采用经验取样法的实证研究论文的内容分析,发现这些文章全面体现了经验取样法的特点、研究内容、样本量、激励方式、数据收集和操作过程等该方法的操作要素。对其进行总结不仅有利于对经验取样法在组织行为学中的应用状况进行总结,而且也能促进这一方法在未来的组织行为学和人力资源管理中的发展和应用。 相似文献

A program is presented that solves for an optimal transformation of data that minimizes skew. Various possible transformations are represented by a function that depends upon a single parameter, λ. A process of iterative approximations is employed to find a value of λ that will transform the data so as to produce a third moment equal to zero. The transformation found by this process may be used as computed or used to indicate which of the commonly employed transformations will most adequately counteract skew. The use of this program in processing data before analysis of variance is discussed. 相似文献

RSCORE-J, a computer program for a signal-detection analysis of pooled rating-method data, is listed and described. RSCORE-J computes jackknife estimates of ROC parameters and their standard errors from rating-method data pooled over a group of observers. 相似文献

A program is described that allows experimenters to generate American Sign Language forms by computer. The computer synthesis of such signs could allow major advances in the experimental investigation of the perception of sign language, much as computer-generated speech has done for the study of speech perception. 相似文献

Although many programs exist for computing tetrachoric correlations, these programs typically lack one or more of the following
features: (1) efficient processing of a large number of variables and computing of a matrix of coefficients; (2) a matrix-smoothing
capability; (3) an accurate, reliable computing algorithm; (4) the ability to handle missing data; and (5) nominal cost. TETCORR,
which combines an algorithm developed by Brown (1977) with starting values obtained from Divgi (1979a) for more efficient
computation, was created to address these and other user concerns. 相似文献

Exploratory factor analysis (EFA) is one of the most widely used statistical procedures in psychological research. It is a
classic technique, but statistical research into EFA is still quite active, and various new developments and methods have
been presented in recent years. The authors of the most popular statistical packages, however, do not seem very interested
in incorporating these new advances. We present the program FACTOR, which was designed as a general, user-friendly program
for computing EFA. It implements traditional procedures and indices and incorporates the benefits of some more recent developments.
Two of the traditional procedures implemented are polychoric correlations and parallel analysis, the latter of which is considered
to be one of the best methods for determining the number of factors or components to be retained. Good examples of the most
recent developments implemented in our program are (1) minimum rank factor analysis, which is the only factor method that
allows one to compute the proportion of variance explained by each factor, and (2) the simplimax rotation method, which has
proved to be the most powerful rotation method available. Of these methods, only polychoric correlations are available in
some commercial programs. A copy of the software, a demo, and a short manual can be obtained free of charge from the first
author. 相似文献
