  • The World Wide Web doubles in size roughly every 2–3 months and dramatic claims are made about the effectiveness of Web‐based commercial efforts. The centrality of non‐price mechanisms of differentiation to the perception, enjoyment and ease of use felt using websites is acknowledged but the only statistically rigorous studies of factors such as form and content have been conducted within a universalist paradigm of aesthetics. This paper reports on an interactionist approach to web aesthetics involving an analysis of 60 male‐ and female‐produced websites. The analysis reveals statistically significant differences between the male‐ and female‐produced websites on 13 out of the 23 factors analysed. These differences span issues of navigation as well as linguistic and visual content. The paper argues that the appeal of websites can be maximised if they mirror the needs and interests of their target populations and that websites targeted at male or female dominated markets need to reflect the aesthetic diversity found in the male‐ and female‐produced websites analysed here. It also presents information on the demographics of the IT profession, showing that there is a potential imbalance between the percentage of women involved online and those involved in the IT profession. This suggests that the male domination of the IT profession could be a barrier to the effective mirroring of female Website preferences.

Choice between sucrose and wheel-running reinforcement was assessed in two experiments. In the first experiment, ten male Wistar rats were exposed to concurrent VI 30 s VI 30 s schedules of wheel-running and sucrose reinforcement. Sucrose concentration varied across concentrations of 2.5, 7.5, and 12.5%. As concentration increased, more behavior was allocated to sucrose and more reinforcements were obtained from that alternative. Allocation of behavior to wheel running decreased, but obtained wheel-running reinforcement did not change. Overall, the results suggested that food-deprived rats were sensitive to qualitative changes in food supply (sucrose concentration) while continuing to defend a level of physical activity (wheel running). In the second study, 15 female Long Evans rats were exposed to concurrent variable ratio schedules of sucrose and wheel-running, wheel-running and wheel-running, and sucrose and sucrose reinforcement. For each pair of reinforcers, substitutability was assessed by the effect of income-compensated price changes on consumption of the two reinforcers. Results showed that, as expected, sucrose substituted for sucrose and wheel running substituted for wheel running. Wheel running, however, did not substitute for sucrose; but sucrose partially substituted for wheel running. We address the implications of the interrelationships of sucrose and wheel running for an understanding of activity anorexia.  相似文献

A total of 50 elderly individuals and 48 college students were tested on several measures of processing speed and of working memory capacity. Language processing was tested with an on‐line measure of sentence processing efficiency, an end‐of‐sentence acceptability judgement task, and a paragraph comprehension test. Elderly individuals performed more poorly than college students on the speed of processing and working memory measures and had longer listening times overall on the sentence processing measures. Elderly individuals did not, however, have overall longer listening times at the most capacity‐demanding regions of the harder sentence types. Correlational analyses failed to establish a relationship between the increase in syntactic processing load at the capacity‐demanding region of the harder sentence type and the measures of working memory capacity, but did establish a relationship between paragraph comprehension and working memory capacity. The data are argued to provide evidence that the WM system used to structure sentences syntactically is separate from that used in other aspects of language comprehension.  相似文献

In the present study, we investigated how well Lee's (1973/1976) typology of love characterized response data that adult subjects provided on selected items written by Hendrick and Hendrick. Results suggest that the model represents response data reasonably well and that Hendrick and Hendrick's (1986) measure ought to be valid.  相似文献

Studies have replicated both negative and positive associations between helpless attributional style and academic performance. Laboratory studies indicate that when enhancement effects occur, they may be moderated by the degree of failure individuals experience prior to task performance. In a longitudinal study of 96 college students who completed four examinations in two introductory psychology courses, we examined the relationship between helpless attributional style and examination performance across the semester, and whether prior examination failure moderated this association. Correlational analyses revealed that helpless attributional style was unrelated to exam performance in the first half of the semester and was positively related to improvements in performance in the second half. Regression analyses indicated that these enhancement effects were not moderated by previous performance on examinations in the course. The present findings underscore the need for longitudinal studies that investigate the pattern of associations between helpless attributional style and performance across time in real-life contexts.  相似文献

Efforts to characterize the memory system that supports sentence comprehension have historically drawn extensively on short-term memory as a source of mechanisms that might apply to sentences. The focus of these efforts has changed significantly in the past decade. As a result of changes in models of short-term working memory (ST-WM) and developments in models of sentence comprehension, the effort to relate entire components of an ST-WM system, such as those in the model developed by Baddeley (Nature Reviews Neuroscience 4: 829–839, 2003) to sentence comprehension has largely been replaced by an effort to relate more specific mechanisms found in modern models of ST-WM to memory processes that support one aspect of sentence comprehension—the assignment of syntactic structure (parsing) and its use in determining sentence meaning (interpretation) during sentence comprehension. In this article, we present the historical background to recent studies of the memory mechanisms that support parsing and interpretation and review recent research into this relation. We argue that the results of this research do not converge on a set of mechanisms derived from ST-WM that apply to parsing and interpretation. We argue that the memory mechanisms supporting parsing and interpretation have features that characterize another memory system that has been postulated to account for skilled performance—long-term working memory. We propose a model of the relation of different aspects of parsing and interpretation to ST-WM and long-term working memory.  相似文献

Temperament and Character Inventory (TCI) and background questionnaire data were collected from a sample of men and women organ donation advocates (N = 362) as part of a national study to investigate their personality characteristics, temperaments, and attitudes about organ donation advocacy. Goals included identifying unique traits for advocates, and response consistency between the TCI and questionnaire. The TCI results included high scores on Cooperativeness and Self-Directedness, and low on Harm Avoidance dimensions. The questionnaire results indicated that most advocates were White, married, college-educated females, who typically spent less than 2 hr with potential donor families, were satisfied with life and job, and believed they would be in a donation position 2 years from the time surveyed. TCI and questionnaire measures were correlated for Self-Transcendence and Spirituality, Helpfulness and Job Satisfaction, and Compassion and Identification variables.  相似文献
