This study examined the effects of text messaging class arrival to an academic counselor on the attendance and punctuality of 4 college student athletes. Each participant had a history of class tardiness and was considered to be at risk for academic failure. Class attendance and punctuality improved for all participants.  相似文献

This paper summarizes three lines of research that are motivated by the practical problem of helping users find information from external data sources, most notably computers. The application areas include information retrieval, text categorization, and question answering. A common theme in these applications is that practical information access problems can be solved by analyzing the statistical properties of words in large volumes of real world texts. The same statistical properties constrain human performance, thus we believe that solutions to practical information access problems can shed light on human knowledge representation and reasoning.  相似文献

Abstract

On 2 April 1535, Robert Singleton, chaplain to Queen Anne Boleyn, preached a sermon at Paul's Cross. The unique, surviving printed copy of the sermon is housed in the Wren Library of Lincoln Cathedral. From 1533, Singleton had been a member of the circle of avant-garde evangelicals gathered at the margins of the Tudor court under the patronage of Thomas Cromwell. His sermon at Paul's Cross contributed to an orchestrated campaign in support of Cromwell's legislative programme, then proceding through Parliament, to sever all links of ecclesiastical jurisdiction with Rome and to confirm Henry's headship of the Church of England. The sermon interprets Paul's allegory of the earthly and the heavenly Jerusalem in the Epistle to the Galatians as a model for thinking about the distinction between the invisible and visible Church. Singleton harnesses Pauline ecclesiology in an apology for the royal supremacy. Presented here is a transcribed copy of the original printed version.  相似文献

Text‐based communication is one of the substantial ways of spreading scientific information. While the content and contextual aspects of written words have been widely researched, the impact of font characteristics on text perception is an almost blank page. The following study deals with the influence of serifs on the evaluation of online‐presented scientific abstracts. Yet there is only evidence for faster reading times when texts are presented in sans‐serif fonts, although the opposite is stated in parts of the literature. The present work examines if the presence or absence of serifs also have an impact on the appraisal of scientific texts when all other important font characteristics do not change. For this purpose, 188 university students participated in an online experiment and rated different aspects of scientific abstracts as well as of the research outlined in the abstracts. The results show that missing serifs led to increased reading speed. However, and in contrast to the perceptual fluency hypothesis, the presence of serifs had a positive effect on all evaluation dimensions. The results of a second study with 187 participants also indicated that reading fluency counteracted the liking of texts. Implications for future studies and media production are discussed.  相似文献

It remains unknown whether mirror reading represents a genuine text processing skill or is based on recognition of visual patterns. The present study attempts to determine whether (1) systematic practice with a particular mirrored typography also improves reading performance for other mirrored typographies, and whether (2) this transfer extends from lexical to numerical material and vice versa. The results show that short-term intensive practice with mirror-reversed words significantly improves reading performance not only for the trained typography but also for other mirrored typographies and mirror-reversed Arabic digits. Practice with mirror-reversed Arabic digits showed a mixed pattern of transfer effects with regard to other digit transformations and there were no transfer effects to lexical material. Hence, for lexical material, at least, improvement after training seems to be based on generalized skill with transfer effects beyond lexical material, rather than on mere improvement of visual recognition of the material used in training.  相似文献

We investigated how working memory capacity (WMC) and text difficulty affect metacomprehension accuracy. Participants completed the operation-span test to measure WMC and ability to read expository texts. Under the easy-text condition, participants read 4 texts with increasing local cohesion, whereas under the difficult-text condition, participants read 4 original texts. Participants assigned a comprehension rating to each text and then completed a comprehension test. The results revealed a significant interactive effect of WMC and text difficulty on metacomprehension accuracy in Experiments 1 and 2. Under the easy-text condition, higher-WMC readers monitored their comprehension less accurately than did lower-WMC readers. In contrast, higher-WMC readers monitored their comprehension more accurately than did lower-WMC readers under the difficult-text condition. These results suggest that text difficulty may affect allocation of attentional resources.  相似文献

In most research on graphics in text students learn the content for a test (e.g., Mayer, 2002). The present study examined whether one of the principles from that literature, namely the deleterious effect of extraneous graphic information, would apply to adults who were consulting a leaflet to answer questions. The study used a mixed factorial design with 48 participants from three age bands (young-adult, young-old, old-old). Participants used two leaflets to answer questions, one without graphics and the other with either extraneous embellishing or supportive explanatory graphics. Relative to leaflets without graphics, the old-old participants were significantly slower finding information when leaflets contained embellishing but not explanatory graphics. The graphics had no effect on the other age groups. These findings suggest that either the reading task or the thematic relevance of the extraneous graphics may limit their negative effects for most adults but that negative effects recur for older readers.  相似文献

Individuals with autism frequently show impairments in text reading comprehension. This often is attributed to poor ability to draw inferences during reading and to inadequate access to relevant knowledge. The current study tested this hypothesis by measuring the time taken to read the same question, relating to either physical or social world knowledge, when it was either relevant or irrelevant to the bridging inference evoked by a preceding two-sentence vignette. In the study, 16 normally developing adolescents and 16 adolescents with autism were matched on word reading accuracy, chronological age, and vocabulary but differed significantly in text comprehension. A strong priming effect was found, robust over participants and over items; participants read those questions that were relevant to the inference evoked by the vignette faster than they read those questions that were irrelevant, and no interaction with group membership or type of knowledge was found. This indicates that readers with autism, just like controls, were activating appropriate world knowledge primed by implicit inferences while reading the vignettes. Thus, the comprehension problems in these readers cannot be attributed to an inability to make implicit inferences or to draw on relevant world knowledge. Instead, we suggest that these problems must be sought at a higher level of text processing.  相似文献
