3 groups of university freshmen took the SAT-V before and after a course in Accelerated Reading. The mean post-test scores for 2 groups increased slightly less than 10 points, while the mean post-test score for the third group decreased significantly. It is concluded that for the type of students used in this study, a course emphasizing speed and accuracy of reading is not of value in increasing scores on the verbal part of the Scholastic Aptitude Test. 相似文献

A model for multiple regression was developed which allows individual differences to emerge empirically. The model encompasses as special cases several of the previous attempts to improve psychological prediction by deviating from the usual linear multiple regression model. The model is tested with both artificial and real data. The results indicate that the model effectively reduces the variance of the error of prediction, and that the weights obtained are stable over different samples, and, to some extent, over different sets of predictors.This article is based upon a thesis submitted in partial fulfillment of the requirements for the doctoral degree at the University of Illinois. The author thanks Professor Ledyard R Tucker who served as committee chairman and offered considerable support and assistance. 相似文献

An adaptation-level model for memory was tested by interpolating different weights between the standard and comparison weights. The results suggest that the model should be modified to account for the general tendency to use alternative categories of judgment with equal frequency. In terms of the modified model, memory for the standard shifts toward the value of the interfering stimulus, the magnitude of shift being proportional to the difference between the interfering stimulus and the value the memory would otherwise have had. 相似文献

The disambiguation of threat/neutral homophones was investigated in high- and low-trait anxiety subjects who had been exposed
to either a positive or a negative mood manipulation procedure. Subjects were required first to spell each auditorily presented
word and second, to generate and speak a sentence using the word. Difference indices were calculated for the spelling and
the sentence usage data, i.e. the number of threat minus neutral interpretations. Examination of these indices revealed that
subjects exposed to the negative mood manipulation procedure produced relatively more threat than neutral interpretations
(for both spelling and sentence usage) than did subjects exposed to the positive mood manipulation procedure. Multiple regression
analyses revealed that both the trait anxiety and mood manipulation variables contributed significantly to the prediction
of the difference index on the spelling task. In the analysis of the use of homophones in sentences, only the mood manipulation
variable contributed significantly to the prediction of the difference index on the sentence usage task. 相似文献

The structure of a course entitled Family Therapy with Major Psychopathology taught annually in the Mercer University Graduate Marriage and Family Therapy Program is presented. An epistemological presentation regarding the interface of psychiatric nosology and family systems assessment is discussed. Methods of diagnosing and assessing dysfunctional family systems are presented and training in individual psychiatric nosology is discussed, with particular attention given to family systems dysfunction as an etiological factor in the development of individual psychopathology. Learning techniques are discussed including lecture, discussion, case presentations, readings, and testing methods. 相似文献

Subjects wielded occluded rods, with or without attached masses, and reported the distances reachable with their distal tips. Experiments 1–3 compared wielding about the wrist, the elbow, and the shoulder. Experiments 4 and 5 compared free wielding, using the whole arm, with wielding only about the wrist. The two comparisons, respectively, were of spatial and temporal variations in the rod’s rotational inertia. Perceived extent was found to be constant in both comparisons. This constancy was tied to the inertia tensorI ij defined about a point that remains a fixed distance from the object during wielding—an invariant of the spatially and temporally dependent patterning of mechanical energy impressed upon the tissues of the body. Discussion focused on the reciprocal action and perception capabilities of multisegmented limbs, the tensorial relations in the neurobiology of dynamic touch, and the strategy of understanding perceptual constancy through invariants. 相似文献

This paper describes the classical understanding of the system ofchakras, or centers of spiritual energy, in tantric yoga. Eachchakra is presented in terms of its traditional understanding. Each is also discussed in the light of contemporary psychological stage theories of development, showing that thechakras can be seen as a model of spiritual development. The preoccupations, concerns, and attitudes associated with eachchakra are portrayed as a mirror of the human mind/heart when spiritual energy is concentrated at that location.She is also founder and chair of the board of Resources for Ecumenical Spirituality. 相似文献
