In six experiments using the speeded classification paradigm, we provide evidence that the ostensibly “separable” dimensions of size and orientation can produce patterns of either separability or asymmetric configurality, depending on the spatial arrangement of the stimuli. In all experiments, subjects classified large or small circles contairting a single line in one of two possible orientations. When the line touched the circle’s perimeter, thereby defining the diameter of the circle (Experiments 1–4), asymmetric configurality obtained: Variations in size interfered with classification by orientation, but variations in orientation did not interfere with classification by size, and redundancy gain was weak or absent. When the lines fell completely within (i.e., did not touch) the circles (Experiments 5 and 6), the results were consistent with separability: There was neither redundancy gain nor interference. Taken together, the results add to the growing body of evidence that classification of specific dimensional pairs as separable or integral may be less feasible than identifying the more general conditions that increase or decrease the psychological salience of dimensional structures and facilitate or interfere with selection of optimal processing strategies.  相似文献

In the context of Question Answering (QA) on free text, we assess the value of answer comparison and information fusion in handling multiple answers. We report improvements in answer re-ranking using fusion on a set of location questions and show the advantages of considering candidates as allies rather than competitors. We conclude with some observations about answer modeling and evaluation methodology, arising from a more recent experiment with a larger set of questions and a greater diversity of question types and candidates.  相似文献

The purpose of this study was to test the relationship between self-efficacy, readiness to change, and Alcohol Use Disorders Identification Test (AUDIT) risk levels in a sample of active duty drinkers who were seeking care in a military emergency department. Civilian health educators screened participants for alcohol use with the AUDIT and collected sociodemographic, service, and drinking-related cognitions data from active duty patients admitted to an emergency department. A total of 787 active duty military personnel participated in the study. Almost half (48%) drank at least once a week and 32% reported consuming five or more alcoholic drinks during a typical drinking episode. One in five participants reported heavy episodic drinking weekly to almost daily. Results of a multinomial logistic regression model showed that active duty service members with a self-reported diagnosis of posttraumatic stress disorder since joining the military were more likely to be an at-risk or high/severe risk drinker relative to a low risk drinker. Higher controlled drinking self-efficacy was associated with a decrease in the odds of being either an at-risk or high/severe risk drinker. Increased readiness to reduce drinking was associated with an increase in the odds of being either an at risk or high/severe risk drinker. The results of this research suggest self-efficacy to control one’s heavy drinking as well as readiness to change may be important factors to consider when designing alcohol education programs within the military.  相似文献

This work examines the intersections of subcultural theories and radicalization theories from terrorism studies to identify how they may be improved through integration. To date there have been almost no efforts to merge these frameworks, though terrorism shares common characteristics of deviant subcultures. Both are driven by ideologies that are in opposition to that of their targets. We focus particularly on the process of online radicalization to assess how subcultural research in online environments may inform the process of enculturation into a terrorist belief system. We conclude by discussing the implications of this expansion for research on terrorism and subcultures.  相似文献

Post-Freudian theories have been criticized for abandoning what is basic to psychoanalysis: the biological body and sexuality as the source of intrapsychic motivation. Arguably, however, they are more present than ever before-for example, in explanations by theorists who propose therapeutic actions beyond interpretation, presymbolic enactments of procedural memories, or disclosures of the analyst's bodily states as an aspect of intersubjectivity. By contrast, the Freudian body was always a text whose mediated meanings require interpretation, for which Freud provided eloquent guides. It is this textuality, and not sexuality, that distinguishes a psychoanalytic approach: a psycho-logic constructed according to a grammar of desire that mediates experience and creates interpretable behavior, both in action and in speech. Theoretical changes in psychoanalysis are traced historically along the dimension of textuality, the example of perversion is invoked, and the conclusion drawn that any theoretical approach, traditional or post-Freudian, that expands an understanding of textuality contributes to the science of psychoanalysis.  相似文献

In the present experiments, we examined whether shifts of attention selectively interfere with the maintenance of both verbal and spatial information in working memory and whether the interference produced by eye movements is due to the attention shifts that accompany them. In Experiment 1, subjects performed either a spatial or a verbal working memory task, along with a secondary task requiring fixation or a secondary task requiring shifts of attention. The results indicated that attention shifts interfered with spatial, butnot with verbal, working memory, suggesting that the interference is specific to processes within the visuospatial sketchpad. In Experiment 2, subjects performed a primary spatial working memory task, along with a secondary task requiring fixation, an eye movement, or an attention shift executed in the absence of an eye movement. The results indicated that both eye movements and attention shifts interfered with spatial working memory. Eye movements interfered to a much greater extent than shifts of attention, however, suggesting that eye movements may contribute a unique source of interference, over and above the interference produced by the attention shifts that accompany them.  相似文献

This research examined the influence of sociocultural paradigms of menopause on attitudes toward menopause. Five hundred eighty-one women and men, between the ages of 18 and 85, were assigned to one of three groups distinguished by the context within which they expressed their attitudes toward menopause. The contexts were designed to reflect particular paradigms: one group described their attitudes toward three medical problems, including menopause; a second group described their attitudes toward three life transitions, including menopause; and a third group described their attitudes toward three symbols of aging, including menopause. Positive and negative subscales of the attitude questionnaires for menopause were analyzed for context and age/experience. Results indicated that the medical context elicited significantly more negative and fewer positive attitudes than did the other two contexts, particularly among older participants. In general, women's attitudes were more positive than were men's, and attitudes became increasingly positive with age and/or experience. The discussion includes the potential role of attitudes as mediating the impact of sociocultural paradigms on experience and behavior.  相似文献
