Perceptual organization is thought to involve an analysis of both textural discontinuities and perceptual grouping. In earlier work, we found that textural discontinuities were detected normally even when visual attention was engaged elsewhere. Here we report how perceptual grouping is affected when visual attention is engaged by a concurrent visual task. To elicit perceptual grouping, we used the Gestalt demonstrations of grouping on the basis of proximity and of similarity. Four tasks were investigated, some requiring the observer to discriminate between horizontal and vertical grouping, and some requiring the observer to merely detect the presence or absence of grouping. Visual attention was engaged at the center of the display by a form identification task. The detection of a textural discontinuity served as a control task. Concurrent form identification conflicted with all four grouping tasks, resulting in a significant reduction of grouping performance in each case. No performance reduction was observed when either form identification or grouping discrimination was combined with the detection of a textural discontinuity. These results suggest that perceptual grouping and form identification compete for visual attention, whereas the detection of a textural discontinuity does not. 相似文献

The aim of this paper is to present a dynamic goal programming scheme. Throughout the revised literature, most of the dynamic goal programming approaches use target values on the final value of the objective functionals. In this paper, dynamic target values are assumed, so that they control not only the final values of the corresponding functionals, but their evolution along the planning period. As a result, the scalar problems are also dynamic ones, where the evolution of the deviation variables is minimized. A lexicographic dynamic goal programming algorithm is developed on these basis, and some considerations are made on the efficiency of the final solutions. © 1998 John Wiley & Sons, Ltd. 相似文献

Relationships between the endorsement of Western beauty ideals and practices and measures of hostility toward women and sexism were studied in 159 college men and 194 college women. The participants were predominately 18 or 19 years of age and of European American ethnicity. Correlations were computed between five factor analytically derived measures of beauty ideals and practices, two measures of the thin body ideal, and the following measures: Hostility toward Women Scale (HTWS; Lonsway & Fitzgerald, 1995), Attitudes toward Women Scale (AWS; Spence & Helmreich, 1978), and the two subscales of the Ambivalent Sexism Inventory (ASI; Glick & Fiske, 1996): hostile sexism (ASI-H) and benevolent sexism (ASI-B). It was found that endorsement of Western beauty ideals and practices was associated with hostility toward women, traditional sexism, hostile sexism, and, to a lesser extent, benevolent sexism. Results support feminist critiques of beauty practices as oppressive. 相似文献

We used a concurrent-task paradigm to investigate the attentional cost of simple visual tasks. As in earlier studies, we found that detecting a unique orientation in an array of oriented elements (“pop-out”) carries little or no attentional cost. Surprisingly, this is true at all levels of performance and holds even when pop-out is barely discriminable. We discuss this finding in the context of our previous report that the attentional cost of stimulus detection is strongly influenced by the presence and nature of other stimuli in the display (Braun, 1994b). For discrimination tasks, we obtained a similarly mixed outcome: Discrimination of letter shape carried a high attentional cost whereas discrimination of color and orientation did not. Taken together, these findings lead us to modify our earlier position on the attentional costs of detection and discrimination tasks (Sagi & Julesz, 1985). We now believe that observers enjoy a significant degree of “ambient” visual awareness outside the focus of attention, permitting them to both detect and discriminate certain visual information. We hypothesize that the information in question is selected by a competition for saliency at the level of early vision. 相似文献

People's self-perception biases often lead them to see themselves as better than the average person (a phenomenon known as self-enhancement). This bias varies across cultures, and variations are typically explained using cultural variables, such as individualism versus collectivism. We propose that socioeconomic differences among societies--specifically, relative levels of economic inequality--play an important but unrecognized role in how people evaluate themselves. Evidence for self-enhancement was found in 15 diverse nations, but the magnitude of the bias varied. Greater self-enhancement was found in societies with more income inequality, and income inequality predicted cross-cultural differences in self-enhancement better than did individualism/collectivism. These results indicate that macrosocial differences in the distribution of economic goods are linked to microsocial processes of perceiving the self. 相似文献

This study reports evidence that individuals with schizophrenia (SC) demonstrate intact attentional selection for visual working memory (WM) storage. A group of 62 participants with SC and 55 control participants without SC were studied in a series of 5 experiments that examined the ability to use top-down and bottom-up cues to guide WM encoding, as well as the ability to spontaneously select a subset of representations for storage. Participants with SC exhibited a consistent and robust ability to use selective attention in the control of WM in all 5 experiments, demonstrating a remarkable island of preserved functioning given the broad spectrum of impairments of attention and WM that have been widely reported in those with SC. These findings indicate that attention is not globally impaired in SC and make it possible to delineate more precisely the nature of the specific impairment of attention in this disorder. 相似文献
