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

This study examined the factor structure, internal consistency reliability, and construct validity of the multidimensional health locus of control (MHLC) instruments developed by K.A. Wallston, B.S. Wallston, and DeVellis (1978) and Lau (Lau, 1982; Lau & Ware, 1981). Both measures were administered to a sample of Veterans Administration (VA) medical outpatients (N = 181). Only minimal evidence of convergence was found between corresponding scales of the two MHLC instruments. Low convergent validity appears attributable to the poor internal consistency reliability of the Lau-Ware subscales. Moreover, results of factor analysis largely supported the a priori factor structure of the K.A. Wallston et al. (1978) MHLC instrument but failed to support the factor structure of the Lau-Ware instrument. Health locus of control (HLC) dimensions that emerged from simultaneous factor analysis of both instruments were most consistent with a three-dimensional typology (i.e., Personal Control, Professional Control, and Chance) rather than the four-dimensional typology proposed by Lau (Lau, 1982; Lau & Ware, 1981). Implications for HLC conceptualization and measurement are discussed. 相似文献

Permanent disruption of aspects of a highly learned skill such as walking force adaptations to occur to the movement. Firstly the body must determine what factors will guide the formation of the new walking pattern, and secondly that new movement pattern must be learned. Frequently the questionable assumption is made that the performance objectives of the new skill are the same as the original. This work used non-linear optimal control and multiple segment simulation to evaluate the ability of several possible objective functions to predict pathological walking patterns. These predictions were then also compared to the results from normal walking. Preliminary results indicate the performance objectives of pathological gaits may be quite different from those of normals. Some support was also provided for the existence of simultaneous multiple performance objectives in complex movements. 相似文献

Two parallel short forms of the Family of Origin Scale were developed from data provided by 69 women and 63 men who completed the full Family of Origin Scale along with a variety of measures of family-of-origin characteristics. Data on the reliability and validity of the short forms are provided and discussed. The results indicate that both short forms are strongly and significantly correlated with each other and with the full-scale version of the FOS and that they share its reliability and validity characteristics to a very high degree. 相似文献
