Word recognition performance varies systematically as a function of where the eyes fixate in the word. Performance is maximal with the eye slightly left of the center of the word and decreases drastically to both sides of thisoptimal viewing position. While manipulations of lexical factors have only marginal effects on this phenomenon, previous studies have pointed to a relation between the viewing position effect (VPE) and letter legibility: When letter legibility drops, the VPE becomes more exaggerated. To further investigate this phenomenon, we improved letter legibility by magnifying letter size in a way that was proportional to the distance from fixation (e.g., TABLE). Contrary to what would be expected if the VPE were due to limits of acuity, improving the legibility of letters has only a restricted influence on performance. In particular, for long words, a strong VPE remains even when letter legibility is equalized across eccentricities. The failure to neutralize the VPE is interpreted in terms of perceptual learning: Since normally, because of acuity limitations, the only information available in parafoveal vision concerns low-resolution features of letters; even when magnification provides better information, readers are unable to make use of it. 相似文献

In standard visual search experiments, observers search for a target item among distracting items. The locations of target items are generally random within the display and ignored as a factor in data analysis. Previous work has shown that targets presented near fixation are, in fact, found more efficiently than are targets presented at more peripheral locations. This paper proposes that the primary cause of this “eccentricity effect” (Carrasco, Evert, Chang, & Katz, 1995) is an attentional bias that allocates attention preferentially to central items. The first four experiments dealt with the possibility that visual, and not attentional, factors underlie the eccentricity effect. They showed that the eccentricity effect cannot be accounted for by the peripheral reduction in visual sensitivity, peripheral crowding, or cortical magnification. Experiment 5 tested the attention allocation model and also showed that RT X set size effects can be independent of eccentricity effects. Experiment 6 showed that the effective set size in a search task depends, in part, on the eccentricity of the target because observers search from fixation outward. 相似文献

Six samples of CCVC phoneme sequences were devised to represent linguistically specifiable distances from existing French words, distance being measured in terms of number of substitutions needed to make an existing French word. Fifty-four native speakers of French rated the sound sequences for their subjective proximity to French, using ungraded rating scales. Results showed a general correspondence between the linguistic and psychological measurements, although certain phoneme sequences did not follow the predicted order. These were examined to see if their displacement could be attributed to the number of different French words reached through substitutions. 相似文献

In this article I argue that Dewey, throughout his work, conducted a systematic dismantling of the concept of rationality as mastery and control. Such a dismantling entails, at the same time, the dismantling of the auto-grounded subject, namely, the subject that grounds itself in the power to master experience. The Deweyan challenge to Western ontology goes straight to the core of the subject’s question. Dewey not only systematically challenged the understanding of thinking as a process consciously managed by the subject but also conceived of thinking as an event rather than a process—something that occurs in us rather than something intentionally staged by a reflective subject. Such a twofold dismantling of rationality and subject rather than a flow in a nihilistic/relativistic account of education results in a reinforcement of education that must be understood not so much as the attempt to understand and predict experience but as the means to create new, unpredictable experience. As a result, education, for Dewey, is grounded on, moved by, and directed at uncertainty. Education, in a sense, engenders uncertainty. 相似文献

The General Health Questionnaire-12 (GHQ-12) is a widely used instrument for measuring psychological strain, but the factor structure of the GHQ-12 is inconclusive. The present study examined one-factor, two- and three-factor models of the GHQ-12 using structural equations modelling in a longitudinal data-set of Hong Kong employees. The findings supported a two-factor model consisting of a ‘Social Dysfunction’ factor measured by three items, and an ‘Anxiety/Depression’ factor measured by four items. Implications and limitations are discussed. 相似文献

As life expectancy increases, interest has grown surrounding the factors that may influence quality of life (QOL) for people with cystic fibrosis (CF). The aim of the current study was to examine which specific coping styles were positively or negatively associated with social and emotional QOL in a CF sample. One hundred and twenty-two respondents aged 18 and over were recruited through an online support group. Respondents completed the ‘CF Questionnaire-Revised (CFQ-R)’ and the ‘Brief COPE’. The CFQ-R is a disease-specific instrument designed to measure the impact of CF on nine QOL domains and the Brief COPE is a 28 item questionnaire which assesses 14 coping scales. A multivariate regression model revealed that higher substance abuse and disengagement was associated with lower emotional QOL whereas greater use of religion, instrumental coping and acceptance was positively associated with emotional QOL. Active coping was linked to better social QOL and a negative association was reported between distraction coping with both emotional and social domains. Given the burden of CF, ascertaining which factors enhance or diminish emotion and social well-being is now an integral component of QOL research. The current findings may therefore have value in informing clinical interventions which aim to cater for the psychological needs of individuals with CF. 相似文献

This article discusses the sources of the 2014 Agreed Statement on Christology, which include not only the 433 Formula of Union and the teaching of St Cyril of Alexandria but also some language from the Council of Chalcedon (451), the Second Council of Constantinople (553), and the Third Council of Constantinople (680–681). It also examines the rejection of Eutychianism and Nestorianism, as well as the Anglican Christology represented by Richard Hooker and the firm connection drawn between the hypostatic union and Christ’s work of salvation. The article also presents the text in comparison and contrast with two Christological declarations shared by the Roman Catholic Church and the Coptic Pope Shenouda III (1973) and the Assyrian Church of the East (1994). 相似文献
