Multivariate nonparametric statistical methods have not been widely used by psychologists. One reason for this may have been that the usual general-purpose packages do not provide easy implementation of these methods. In this article, we briefly describe the multivariate extensions of the sign, signed-rank, and rank-sum tests and use S, a programming environment for data analysis, to implement these statistical procedures. Three numerical examples are used to illustrate the flexibility and efficiency of these computations in S. 相似文献

A new paradigm is proposed that involves a simple judgment on an object’s perceptual feature that is independent of object identity. Subjects were required to categorize as vertical or horizontal the main axis of elongation of an object picture. Both fake and real-world objects were presented, and a graphical manipulation was applied to their shapes so that the canonical elongation of the real-world objects was incongruent with the elongation of their shapes after the manipulation. The results showed an influence of the identity of the objects on the perceptual task in the form of a cost in judging the elongation of the incongruent real-world objects. The results are taken as evidence for automatic activation of objects’ stored representations. A “horse-race” model of the influence of these representations on the perceptual task is proposed in the final section of the article. 相似文献

Since 1972, the direction of policy concerning development of Aboriginal Australian communities has been towards adoption
of the notion of self-determination. This paper presents a case study of how one particular Aboriginal community has combined
local knowledge with non-Aboriginal knowledge to develop an alternative mathematics curriculum that will promote community
development and authentic self-determination. 相似文献

Videobased corneal-reflection-to-pupil-center systems are widely used in eye movement research. In this paper, an artificial eye drawn on a computer screen is presented. The artificial eye provides a way to simulate measurements of eye position in human subjects. The method allows testing videobased systems on the level of the signal and on the level of the calibration algorithm used to map the eye position parameters to stimulus space. In addition, the artificial eye can be used to evaluate specific hypotheses concerning the functioning or malfunctioning of the eye recorder and as a help in developing data analysis programs. 相似文献

Eye movements were recorded while subjects read passages of text repeatedly (Experiment 1) and while normal text and strings ofhomogeneous letters were fixated (Experiment 2). Text repetition decreased fixation durations and increased saccade size, presumably because it decreased attention demands. Irrespective ofrepetition, however, no distinct distribution of brief (express) fixations emerged. In Experiment 2, fixation durations were shorter and saccades were larger when strings of homogeneous letters were “read,” indicating that this condition decreased attention demands. Again, however, no distinct distribution of express fixations emerged. These findings pose problems for the view that attentional processes determine the occurrence of brief (express) fixation durations in reading. Supplementary analyses of Experiments 1 and 2 suggested that visuospatial processing affected fixation durations, irrespective of linguistic processing demands. 相似文献

Two experiments were performed with incidental study procedures in which generation effects were observed for relatively balanced French-English bilingual subjects on measures of both free recall and recognition. Experiment 1 used a within-subject design, and Experiment 2 used a between-subject design. In both experiments, reading translations and reading same-language repetitions generally resulted in similar amounts of retention. Experiment 2 and Experiment 3 also showed that the generation effect was abolished under intentional study procedures because of an enhancement of reading-based retention. The results suggested that previous failures to obtain a translation-based generation effect may have been due to the use of intentional study procedures. The pattern of effects was explained in terms of a single-code model of bilingual linguistic representation and an individual-item processing intetpretation of the generation effect. 相似文献

This paper describes simple and flexible programs for analyzing lag-sequential categorical data, using SAS and SPSS. The programs read a stream of codes and produce a variety of lag-sequential statistics, including transitional frequencies, expected transitional frequencies, transitional probabilities, adjusted residuals, z values, Yule’s Q values, likelihood ratio tests of stationarity across time and homogeneity across groups or segments, transformed kappas for unidirectional dependence, bidirectional dependence, parallel and nonparallel dominance, and significance levels based on both parametric and randomization tests. 相似文献
