In the present study, we manipulated different types of information available in the parafovea during the reading of Chinese sentences and examined how native Korean readers who learned Chinese as a second language make use of the parafoveal information. Results clearly indicate that, only identical and orthographically similar previews facilitated processing of the target words when they were subsequently fixated. More critically, more parafoveal information was obtained by subjects with higher reading proficiency. These results suggest that, mainly low-level features of the parafoveal words are obtained by the non-native Chinese readers and less attentional resources are available for the readers with lower reading proficiency, thereby causing a reduction of the perceptual span.  相似文献

Work values stability, change, and development can be appreciably reduced to a living system model [Ford, D. H. (1994). Humans as self-constructing living systems: A developmental perspective on behavior and personality (2nd ed.). Hillsdale, NJ: Lawrence Erlbaum Associates]. This theoretical model includes discrepancy-reducing and cohesion-amplifying mechanisms that interact to govern the change in standard- and goal-oriented work values over time [Boldero, J., & Francis, J. (2002). Goals, standards, and the self: reference values serving different functions. Personality and Social Psychology Review, 6(3), 232-241]. Employing longitudinal data from a sample of adolescents (n = 1010) spanning the 9th through the 12th grades, the results demonstrate that the value system develops in a theoretically predictable fashion during the adolescent period. Discrepancy reduction and cohesion mechanisms interact to either maintain or increase the integrity of and harmony between standard-oriented values associated with high school part-time work experiences and goal-oriented work values related to anticipated career-oriented work during adulthood. Exploratory analyses suggest that adolescents’ educational expectations influence the relative salience of standard- and goal-oriented work values and the discrepancy reduction process linking the two over time.  相似文献

Drawing on data collected from two longitudinal Cohort Studies following the lives of over 20,000 individuals born in the United Kingdom 12 years apart in 1958 and 1970, respectively, this paper examines antecedents and outcomes of educational and occupational aspirations of young men and women, covering the transition from dependent childhood into independent adulthood. Two analytical models, a Social Reproduction Model and a Developmental-Contextual Model are tested to assess the processes by which family background and the wider socio-historical context influence work and family related careers. The findings demonstrate the persistent role of gender, social origin and individual agency processes as well as the influence of a changing socio-historical context on career development. Results are interpreted with regard to biographical agency processes linking individual lives with social contexts across the life course.  相似文献

The influence of attention on perceptual awareness was examined using metacontrast masking. Attention was manipulated with endogenous cues to assess the effects on the temporal and spatial parameters of target visibility. Experiment 1 examined the time course of effective masking when the target and mask set were presented at an attended vs. an unattended location. The valid allocation of attention decreased the magnitude of the masking effect (i.e. increased visibility) for approximately 80 ms. Furthermore, even with spatial displacements of the target and mask and center-to-center separations of 1.5 degrees or 2.7 degrees of visual angle (Experiment 2), target visibility was increased when attention was validly allocated. These results indicate that attention influences low-level visual processes to enhance visual awareness.  相似文献

This article assesses the significance of Baker et al., Equality: from Theory to Action from the perspective of current concerns occupying legal equality scholars in the UK, focusing in particular on the practical relevance of equality studies to the kinds of issues arising from the debate over the new Commission for Equality and Human Rights (CEHR). The article highlights and considers key issues, including the delineation of the sphere of inequality protection, the normative content of the concept of equality espoused by law and the potential of law to reach beyond its current limits to embrace the broader dimensions of (in)equality identified in Baker et al.’s account.  相似文献

Although ethnic minorities are overrepresented in pedestrian-vehicle collisions, previous driving studies did not examine racial attitudes in such collisions. Our objective was to determine whether the speed of a driver’s response to a pedestrian was affected by the driver’s racial attitudes and the contrast between the pedestrian’s skin colour and background. Participants viewed simulated driving scenes of a pedestrian on a road and pressed a button as soon as they saw an obstacle. Visual information, but not racial attitudes, affected the time it took observers to respond to pedestrian and non-pedestrian stimuli in driving scenes. Results indicated that contrast affected response time even when the stimulus was subliminal. We believe this is the first demonstration of contrast effects with subliminal stimuli in a driving context. Results have implications for traffic safety and for methodology used to study racial attitudes.  相似文献

This paper replies to Politzer’s (2007) criticisms of the mental model theory of conditionals. It argues that the theory provides a correct account of negation of conditionals, that it does not provide a truth-functional account of their meaning, though it predicts that certain interpretations of conditionals yield acceptable versions of the ‘paradoxes’ of material implication, and that it postulates three main strategies for estimating the probabilities of conditionals.  相似文献

Expert chess players, specialized in different openings, recalled positions and solved problems within and outside their area of specialization. While their general expertise was at a similar level, players performed better with stimuli from their area of specialization. The effect of specialization on both recall and problem solving was strong enough to override general expertise—players remembering positions and solving problems from their area of specialization performed at around the level of players 1 standard deviation (SD) above them in general skill. Their problem-solving strategy also changed depending on whether the problem was within their area of specialization. When it was, they searched more in depth and less in breadth; with problems outside their area of specialization, the reverse. The knowledge that comes from familiarity with a problem area is more important than general purpose strategies in determining how an expert will tackle it. These results demonstrate the link in experts between problem solving and memory of specific experiences and indicate that the search for context-independent general purpose problem-solving strategies to teach to future experts is unlikely to be successful.  相似文献
