An information-theoretic framework is used to analyze the knowledge content in multivariate cross classified data. Several related measures based directly on the information concept are proposed: the knowledge content (S) of a cross classification, its terseness (Zeta), and the separability (Gamma
X
) of one variable, given all others. Exemplary applications are presented which illustrate the solutions obtained where classical analysis is unsatisfactory, such as optimal grouping, the analysis of very skew tables, or the interpretation of well-known paradoxes. Further, the separability suggests a solution for the classic problem of inductive inference which is independent of sample size. 相似文献

After training under short or long fixed-interval schedules, humans responded under a modified fixed-interval schedule in which magnitude of reinforcement (X or 2X) was minimally correlated with response frequency. Response frequencies that equaled or exceeded a minimum response criterion were followed by the larger reinforcer at the end of the interval; otherwise, the smaller reinforcer was delivered. The modified schedule alternated with the baseline schedule across conditions. In a control condition, the reinforcer magnitudes produced by control subjects were yoked to those of experimental subjects. Experimental subjects, but not control subjects, showed increased responding. In addition to the baseline and modified fixed-interval schedules used in Experiment 1, subjects in Experiment 2 also responded under a second modified fixed-interval contingency in which increases in reinforcer magnitude were more highly correlated with response frequency. Experimental subjects, but not control subjects, showed increased responding under both procedures. Direct comparison of these two procedures showed that the high-correlation procedure produced greater increases in responding than did the low-correlation procedure. 相似文献

Spinal cord injury can cause cognitive impairments even when no cerebral lesion is appreciable. As patients are forced to explore the environment in a non-canonical position (i.e., seated on a wheelchair), a modified relation with space can explain motor-related cognitive differences compared to non-injured individuals. Peripersonal space is encoded in motor terms, that is, in relation to the representation of action abilities and is strictly related to the affordance of reachability. In turn, affordances, the action possibilities suggested by relevant properties of the environment, are related to the perceiver's peripersonal space and motor abilities. One might suppose that these motor-related cognitive abilities are compromised when an individual loses the ability to move. We shed light on this issue in 10 patients with paraplegia and 20 matched controls. All have been administered an affordances-related reachability judgement task adapted from Costantini, Ambrosini, Tieri, Sinigaglia, and Committeri (2010, Experimental Brain Research, 207, 95) and neuropsychological tests. Our findings demonstrate that patients and controls show the same level of accuracy in estimating the location of their peripersonal space boundaries, but only controls show the typical overestimation of reaching range. Secondly, patients show a higher variability in their judgements than controls. Importantly, this finding is related to the patients’ ability to perform everyday tasks. Finally, patients are not faster in making their judgements on reachability in peripersonal space, while controls are. Our results suggest that not moving freely or as usual in the environment impact decoding of action-related properties even when the upper limbs are not compromised. 相似文献

Over the past three decades, the theory of religious economy has been established, applied, debated, developed, and rejected. It has proven to be as divisive as any "general theory" of religion should be, and yet its core tenets continue to engage and unite scholars around the world. In response to broader shifts within the sociology of religion, this article reframes religious economy by advancing a spatial approach to its theorization. A spatial approach can help develop new perspectives on the regulation of religion, and the resistant agency of religious groups. With a focus on the "secular monopoly" of Singapore, it demonstrates how the restricted supply of land for religious purposes increases competition between religious groups. To overcome restrictions, religious groups pursue strategies of spatial and organizational boundary crossing. This has led to the closer regulation of space, and highlights the recursive interplay between the regulation and praxis of religion in Singapore. 相似文献

When depression alternates with mania, as in a bipolar affective disorder, creativity might be enhanced. To investigate this, we employed a single‐subject design, looking at both affective space and the spectral covariation of mood and creativity in a participant presenting with bipolar affective disorder. The study was conducted over a period of 54 days, and employed a standard measure of mood (the Brief Mood Introspection Scale) and a standard task of creativity (Alternative Uses Task). Both positive affect and negative affect appear to be somewhat undifferentiated for this participant, and her mood space does not conform to that described by the accepted major dimensions of Arousal and Pleasure. Conceivably, this is because of her rapid mood fluctuations. A 2.7‐day periodicity was found for Tired, Peppy, Nervous, and Calm, on the one hand, and ideational fluency, ideational flexibility, and originality, on the other. In addition, a 9‐day periodicity was common to Happy, Sad, and Gloomy—all three affects clustering in the same affective space—together with both ideational flexibility and originality. This finding brings into question the relationship between creativity and both positive and negative mood. 相似文献

While research on the spatial representation of number has provided substantial evidence for a horizontally oriented mental number line, recent studies suggest vertical organization as well. Directly comparing the relative strength of horizontal and vertical organization, however, we found no evidence of spontaneous vertical orientation (upward or downward), and horizontal trumped vertical when pitted against each other (Experiment 1). Only when numbers were conceptualized as magnitudes (as opposed to nonmagnitude ordinal sequences) did reliable vertical organization emerge, with upward orientation preferred (Experiment 2). Altogether, these findings suggest that horizontal representations predominate, and that vertical representations, when elicited, may be relatively inflexible. Implications for spatial organization beyond number, and its ontogenetic basis, are discussed. 相似文献

This article defines healthy oneness experience and establishes the progressive, life enhancing components of the experience. The author clarifies the paradox that a cohesive, well-integrated self allows unitive, non-self-definitional experiences. The author attempts to work the cultural/clinical border by exploring oneness phenomena as they occur in art, religion, literature and the clinical consulting room. The author uses psychoanalytic tools to understand non-clinical experiences of oneness. Through compelling accounts of such experiences as described by artists, writers and meditators, psychoanalytic theorizing about oneness is illumined further. 相似文献

In this study, we investigated the effect of an indoor plant on task performance and on mood. Three room arrangements were used as independent variables: a room with (1) a plant, or (2) a magazine rack with magazines placed in front of the participants, or (3) a room with neither of these objects. Undergraduate students (M= 35, F= 55) performed a task of associating up to 30 words with each of 20 specified words in a room with one of the three room arrangements. Task performance scores showed that female participants performed better in view of the plant in comparison to the magazine rack (p < 0.05). Moreover, mood was better with the plant or the magazine rack in the room compared to the no object condition (p < 0.05). However, the difference in task performance was highly influenced by the evaluation about the plant or the magazine rack. It is suggested that the compatibility between task demand and the environment is an important factor in facilitating task performances. 相似文献
