The World-Wide Web (WWW) is a wide-area hypermedia information-retrieval initiative that aims to give access to a large universe of documents. Through software such as Mosaic, the WWW provides a simple, consistent means to access a variety of information stored as text, graphics, video, and sound files. This paper details the requirements for using this software, illustrates some current and planned hypermedia databases, and addresses issues that could affect the greatest possible utilization of the system. 相似文献

Experiment 1 assessed the time and effort allocated to writing subprocesses while generating written and verbal protocols over 10 weekly writing sessions. Within a 40-min session, planning time consumed about 45% in the first 5 min, but stabilized at near 30% thereafter. Generating text initially consumed 40% of the writers’ time, peaked at 50% midway, and then declined to its original level. The time spent revising and reviewing was negligible early in writing sessions, but increased substantially late in the sessions. The highest and lowest quality documents could be differentiated on the basis of the amount of time the writers devoted to revising and to the magnitude of their RTs in a secondary interference task. Writers showed consistent, distinctive patterns of transitional probabilities between writing subprocesses both within and across sessions, yielding quantitative representations of their writing styles. In Experiment 2, writers overestimated the amount of time they devote to revising and overestimated the amount of effort they allocate to planning and text generation. Their estimations did not improve after 10 weeks of composing. A time-and-effort-based analysis of writing is proposed to account for these data. 相似文献

Respiratory pumping in the marine gastropod Aplysia is a well-characterized behavior controlled by identified neurons. The behavior is affected by stimuli such as change in ambient pH and shock. This study investigates learned changes in effects of these stimuli on rate of respiratory pumping movements. A sharp threshold exists for effects of environmental pH on respiratory pumping. Lowering the ambient pH from 7.8 to 7.0 does not affect the rate of respiratory pumping movements, but when pH is decreased further to 6.5 a large increase in pump rate is seen. Sensitizing stimuli, such as brief head shock and preexposure to pH 7.0, change the threshold so that respiratory pumping rate is increased in pH 7.0. Pairing exposure to pH 7.0 with head shock leads to pairing-specific amplification of the response in pH 7.0 alone. Pairing-specific consequences can be distinguished from sensitization only after an hour. 相似文献

Unconscious fantasy: a reconsideration of the concept 总被引:1,自引:0,他引:1
Despite general agreement about the clinical importance of unconscious fantasy, the concept itself has remained unclear. After reviewing Freud's work on the subject, the conceptual dilemma is specified: where in current psychoanalytic theory do we place this important, dynamically repressed, structuralized mental content? Three conceptual paths have been followed in attempting to deal with this problem. The first emphasizes the structural, tripartite model, discarding topographic concepts. The second replaces the structural model with a schema model borrowed from academic psychology. The third combines the structural and topographic models. None of these approaches is entirely satisfactory and without problems. Because of their central role in mental life, unconscious fantasies deserve careful definition. They should be distinguished from conscious fantasies and daydreams as well as from the process of fantasizing. They are differentiated from other varieties of unconscious content by their enduring quality and their organized, storylike quality reflecting the distortions typical of the primary process. As dynamically unconscious templates from the childhood past, they shape subsequent compromise formations and are relatively impervious to new experience. The development of psychoanalytic theory from a macrostructural to a microstructural emphasis is discussed in relation to the unconscious fantasy concept. 相似文献

Sixty 33–60-month-old children's gender role knowledge, gender role flexibility, and gender schematization were assessed. Parents completed questionnaires describing aspects of their child's social environment. Results indicated that boys who reportedly interacted more with their fathers, and girls who interacted more with both parents, exhibited greater gender schematization. Children who interacted more with parents displayed less gender role flexibility. Girls with mothers who worked outside the home demonstrated greater gender role flexibility. Boys with many siblings displayed greater gender role knowledge. Children with fewer siblings displayed greater gender role flexibility. Boys favoring entertainment television demonstrated greater gender role knowledge. Girls favoring educational television displayed greater gender role flexibility. Future research and theory evaluating the interactive effects of social and cognitive factors on boys' and girls' gender role development are encouraged. 相似文献
