In a recent paper, four-look recognition performance was predicted from one-look (lL) data by Bayes’s theorem, with the entire pattern of two Ss’ four-look data being predicted reasonably well. In the present study, three Ss were run, with the addition that feedback was given and confidence judgments were required. Their task was to identify tachistoscopically presented graphemes A, T, or U. Predictions of four-look performance were made using three orders of lL data matrices, differing in the breakdown of confidence categories. The three matrices led to reasonably accurate predictions. Predictions varied somewhat in accuracy, depending on the order of the lL matrix. The possibility that the variation in predictive accuracy reflected the capacity of an S to combine information received from each observation was discussed. The capacity question is presently under investigation by the authors. 相似文献

Apple Psych, a system of software subroutines written in Apple Pascal and 6502 assembly language, was designed to run real-time psychological experiments on the Apple II, II+, and IIe microcomputers. This paper describes the minimum system requirements necessary to run Apple-Psych, the capabilities of the basic system, and the advantages and disadvantages of using Apple-Psych. Because the utility of a system to a researcher is often linked to its flexibility and expandability, this paper includes a brief discussion of hardware expansions already supported by the Apple Psych software and hardware expansions that would require additional software support. 相似文献

Do Reentry Women Have Special Needs? 总被引:1,自引:0,他引:1
Reentry and nonreentry women were compared on their reasons for being in school, goals associated with education, and campus services used or wanted. Eighty-two California State University, Hayward, undergraduate students volunteered to participate in the questionnaire survey. Reentry women were found to be more self-motivated, with higher educational goals, and higher grade point averages than nonreentry women. Reentry women also made less use of currently available student services. Reasons for this lack of use, and suggestions for future services were explored. 相似文献

A total of 670 undergraduate Ss were tested in three studies conducted in an attempt to define a set of cues that minimally specify perceived “frontness” and “backness” of objects. In Experiment I, Ss were instructed to identify the “front” and “back” of printed squares to which no, one, or two circles were attached. In Experiment II, different Ss made the same kind of judgment to a wider range of geometric forms. In Experiment III, different Ss judged the direction of “imagined” movement of forms from Experiment I. The results indicated that the “front” and “back” are asymmetric opposite sides, with “front” the side most different from the rest and the side toward which the form is imagined to be moving. 相似文献

Symptomatic of a contemporary concern with affective factors in cognitive processing, a corpus of research is now emerging on the role of interestingness in discourse processing. This research has concentrated on narrative prose and has adopted a structural approach, arguing for the centrality of event and discourse structure in producing an affect like interest. The authors point out that this approach considers only one type of interest—knowledge-triggered—to the exclusion of another important type—value-triggered. A more comprehensive understanding of interest will only be achieved by researching other genres, such as exposition, and by considering the multiple sources of interest-producing conditions. We suggest the notion of “informational significance” as an inclusive term, and underline the need for a process-based understanding of interest. 相似文献

Meta-analytic structural equation modeling (MASEM) is increasingly applied to advance theories by synthesizing existing findings. MASEM essentially consists of two stages. In Stage 1, a pooled correlation matrix is estimated based on the reported correlation coefficients in the individual studies. In Stage 2, a structural model (such as a path model) is fitted to explain the pooled correlations. Frequently, the individual studies do not provide all the correlation coefficients between the research variables. In this study, we modify the currently optimal MASEM-method to deal with missing correlation coefficients, and compare its performance with existing methods. This study is the first to evaluate the performance of fixed-effects MASEM methods under different levels of missing correlation coefficients. We found that the often used univariate methods performed very poorly, while the multivariate methods performed well overall. 相似文献
