Data from the 1976 American National Election Study were used to assess the effects of one outgroup characteristic, belief similarity—dissimilarity, on the enhancement of women's feminist consciousness. Women were focused on as the ingroup and men as the outgroup. The sample consisted of 677 women who believed that women should have an equal role with men. Outgroup belief similarity referred to women's perception that most men supported an equal role for women and outgroup dissimilarity to the perception that men did not support an equal role. Results indicated that outgroup belief similarity significantly enhanced women's feminist consciousness. Women who supported an equal role and perceived outgroup belief dissimilarity scored higher on cognitive and behavioural measures of feminist consciousness than those who supported an equal role but did not perceive outgroup dissimilarity. Secondary analyses were undertaken assessing the effect of ingroup belief similarity dissimilarity on the enhancement of sympathetic feminist consciousness among men. 相似文献

Summary Among mathematical models of visual confusion of letters and similar material, those that posit a feature detection process have been especially popular. The present study provides direct tests of several of the central assumptions of such models with feature-stimuli composed of the blank, one of two straight line features, or both line features positioned at a right angle. In one condition, the two features were connected when they appeared together, whereas in the other condition they were separated by a gap. A model which makes the strong assumptions that the features are sampled (detected) independently and then reported in a direct, unbiased fashion, performed acceptably in both conditions. Feature dependency models and those positing a biased decision process were ruled out on the basis of poor fits or lack of parsimony. The perceptibility (d) of a specific feature depended on the stimulus that contained it in the Gap condition but not in the Connected condition. The relative perceptibility of the horizontal vs in the vertical features was also different in the Gap vs Connected conditions. The results were compared with other recent studies, including ones in which sampling independence was falsified, apparently because of greater stimulus complexity, and employing a stimulus set that did not contain all possible combinations of features.We would like to thank J.T.

A theory of matching processes is developed within which serial models and parallel models based on within-stage independent intercompletion times are defined. These models are then specialized to a class of processes possessing exponential intercompletion time densities and equivalence properties of parallel and serial models within this class are investigated. Nonequivalence theorems are proved that designate possible differences in “same” (+) and different (?) matching rates as important in testing parallel and serial models. An experimental paradigm is then derived with the property that if + rates are different from — rates, and if processing is self-terminating, then the parallel and serial models are distinguishable at the level of mean reaction times. The serial class of models that is tested by this paradigm includes a large number of stochastic distributions whose central assumption is additivity of element processing times. The corresponding parallel class of models is currently limited to those assuming exponential intercompletion times. A numerical example and an example of non-parametric relations predicted by the serial or parallel models are given. Some advantages and limitations of the present treatment are discussed. 相似文献

Linear arrays of 1, 8, and 9 letters were exposed while S read off the items of the letter sequence while maintaining constant fixation. By this procedure, serial position effects were studied in the absence of requirements for scanning the array quickly, as in a tachistoscopic display, and for remembering a large number of items, as in a delayed whole report. Despite the absence of these requirements, typical serial position curves were generated. Serial position effects were partially ameliorated by the introduction of blank spaces into the array. Performance was influenced both in the immediate vicinity of the blank spacings, as well as extending over a large portion of the array. The data were interpreted in terms of lateral masking effects associated with adjacent elements. 相似文献

An earlier article reported extensive analyses of confusion data compiled from group averages (Townsend, 1971). The present study provided for essentially the same analyses with different long-term data obtained with two individuals, the primary intent being to examine the ability of recognition and scaling models to explain data at the individual level (which the recognition models purport to describe) and to compare the confusion characteristics of the English uppercase alphabet between the two Ss and between the individual Ss and the group-averaged data. The choice and overlap models were superior to the all-or-none model in predicting the empirical confusion matrices and tended to explain the data structure in a similar manner. Multidimensional scaling analysis again supported a Euclidean metric and suggested four or five underlying stimulus dimensions. However, as before, there were no overriding intuitively appealing psychological dimensions corresponding to these, and possible reasons are discussed. The choice and overlap models appeared to fit as well or better at the individual level than at the group level and the all-or-none model to fit worse. In the present study, probability correct was fit even better by the all-or-none model than in the group study and replicated the result of being better here than the overlap and choice models. Individuals and the group were consistent in their sensory confusions as represented by similarity parameters in the choice and overlap models but differed in their response biases. A simple measure of physical similarity explained 50% of the variance of the similarity structure in the confusion data. 相似文献

Mother and daughter perceptions of their relationship: the influence of adolescent pregnancy status 总被引:1,自引:0,他引:1
This investigation focused on the perceived relationships between 95 mothers and their adolescent daughters. It sought to determine if there was a significant difference in the mother-daughter relationship as perceived by pregnant versus nonpregnant adolescents, and whether the mothers of these two groups, when compared to each other, differed in their feelings for their daughters. In contrast to other investigations, no striking differences between the groups in intimacy, attachment, and strength of feeling as indicated by a questionnaire were found, though results were generally in the predicted direction. Nevertheless, a strong correlation between daughters' and mothers' answers was found, indicating an overall positive perception by both toward their relationship. 相似文献

Children aged 3, 4, and 5 years and adults heard sentences with clauses connected by after, and, or before, saw a picture, and indicated whether or not the picture matched one of the events of the sentence. Response times were taken as a measure of immediate accessibility to the meaning of the clause that the picture was about. Temporal organization of sentence meanings was dominant in 3-year-olds and adults, but not in 4- or 5-year-olds. The 3-year-olds and especially the adults processed and-sentences as implicitly temporal. The results for 4- and 5-year-olds are interpreted as indicating experimentation with alternate strategies for organizing sentences based on the structural/presuppositional properties of clauses. 相似文献

This paper investigates the consequences of extending the assumptions of pure insertion and selective influence (popular in RT theorizing) to the level of the distribution. In the case of pure insertion and under the additional assumption that the additive random variable is exponentially distributed, a solution is obtained which not only allows estimation of the exponential-rate parameter but also provides a test of the assumptions. The result is shown to be applicable not only when processing is serial but also for certain parallel models. In addition, discrimination between self-terminating and exhaustive search strategies is provided, and in the case of either, both parameter estimation and tests of the model are possible. Extensions to nonexponential models are investigated and a general method of moments solution is outlined. In the case of selective influence a general nonparametric alternative to Sternberg's additive factor method is developed. The problem of empirical estimation and application is then considered. Simulations which place bounds on the type I and II error are reported. Finally the first theorem is provided an illustrative application with data from a memory scanning experiment. The results provide some support for the double assumption of pure insertion and that the additive random variable is distributed exponentially. 相似文献
