Vocal reaction times were measured in Italian dyslexics and in proficient readers while they read single words. Three groups of control participants (for a total of 79) were tested. All were in the first, second or third grade of elementary school. Nine third graders with a low level of reading ability when assessed by standard reading procedures were also tested. Results indicated that vocal RTs of control participants were faster and less sensitive to word length as a function of age; also, there was a particularly marked change between first and second graders. Dyslexics' vocal RTs and errors were much worse than those of peer control participants and resembled those of first grade controls. It is suggested that normal readers in an orthographically transparent language (Italian) adopt a lexical strategy quite early in their learning. On the contrary, dyslexics seem unable to learn this mode of processing and continue to use a sub-lexical reading procedure. 相似文献

The formation of two misfit edge dislocations is theoretically investigated in the interfaces of a layer embedded in a semi-infinite matrix. Assuming the matrix–layer interfaces are partially coherent, the energy variation resulting from the formation of the dislocations from the lateral free surface of the structure has been determined in the shearing stress field due to the partial misfit. The mechanical stability of the structure is analysed with respect to the dislocation formation as a function of the size of the coherent region of the interface and the misfit strain. 相似文献

AbstractAccording to epistemic instrumentalism (EI), epistemic normativity arises from and depends on facts about our ends. On that view, a consideration C is an epistemic reason for a subject S to Φ only if Φ-ing would promote an end that S has. However, according to the Too Few Epistemic Reasons objection, this cannot be correct since there are cases in which, intuitively, C is an epistemic reason for S to Φ even though Φ-ing would not promote any of S’s ends. After clarifying both EI and the Too Few Epistemic Reasons objection, I examine three major instrumentalist replies and argue that none of them is satisfactory. I end by briefly sketching a fourth possible response, which is, I suggest, more promising than the other three. 相似文献

AbstractThis study investigates the interplay between family risk and the quality of classroom interactions and their impact on self-regulation skills in two groups of children—children from socioeconomically disadvantaged backgrounds (at-risk) and non-risk children. Participants included 485 children (N = 93 classrooms)—233 (N = 47 classrooms) of which were from socioeconomically disadvantaged areas. Temperament was measured using teacher report. Trained observers rated classroom quality via live observations of a typical preschool day. Behavioral regulation was assessed using direct measures and emotional regulation was assessed using a teacher report. Analyses using multiple group structural equation modeling showed that at-risk children had lower levels of cool behavior regulation than non-risk children. In addition, classroom quality was positively linked to cool behavioral self-regulation. Moderating effects were additionally found between family risk and classroom quality on both hot behavioral regulation and emotional regulation. Classroom quality served as a protective factor for children exposed to more risk factors. Results showed complex associations between individual characteristics, classroom quality, and family risk, indicating a need to further explore the interplay among these variables. 相似文献

Developmental dissociation in the neural responses to simple multiplication and subtraction problems
Mastering single‐digit arithmetic during school years is commonly thought to depend upon an increasing reliance on verbally memorized facts. An alternative model, however, posits that fluency in single‐digit arithmetic might also be achieved via the increasing use of efficient calculation procedures. To test between these hypotheses, we used a cross‐sectional design to measure the neural activity associated with single‐digit subtraction and multiplication in 34 children from 2nd to 7th grade. The neural correlates of language and numerical processing were also identified in each child via localizer scans. Although multiplication and subtraction were undistinguishable in terms of behavior, we found a striking developmental dissociation in their neural correlates. First, we observed grade‐related increases of activity for multiplication, but not for subtraction, in a language‐related region of the left temporal cortex. Second, we found grade‐related increases of activity for subtraction, but not for multiplication, in a region of the right parietal cortex involved in the procedural manipulation of numerical quantities. The present results suggest that fluency in simple arithmetic in children may be achieved by both increasing reliance on verbal retrieval and by greater use of efficient quantity‐based procedures, depending on the operation. 相似文献

Studies concerning the perceptual processes of animals are not only interesting, but are fundamental to the understanding of other developments in information processing among non-humans. Carefully used visual illusions have been proven to be an informative tool for understanding visual perception. In this behavioral study, we demonstrate that cuttlefish are responsive to visual cues involving texture gradients. Specifically, 12 out of 14 animals avoided swimming over a solid surface with a gradient picture that to humans resembles an illusionary crevasse, while only 5 out of 14 avoided a non-illusionary texture. Since texture gradients are well-known cues for depth perception in vertebrates, we suggest that these cephalopods were responding to the depth illusion created by the texture density gradient. Density gradients and relative densities are key features in distance perception in vertebrates. Our results suggest that they are fundamental features of vision in general, appearing also in cephalopods. 相似文献

To encourage the adoption of protective recommendations, health communications often include vivid information depicting the features of relevant threats. Despite a large body of research on threatening communications, little attention has been yet given to threat vividness. Across three experiments, we thus tested whether including a vivid (vs. pallid) threat in a health communication affects the acceptance of recommendations. Results revealed greater responses when people were exposed to a vivid threat, relative to a pallid threat. However, we also demonstrated that such beneficial effects were dependent on threat severity and vulnerability to the threat. Taken together, these findings underscore the importance of distinguishing the effects of the threat from those of its vividness. 相似文献

This article addresses the debate concerning cultural differences in independent and interdependent self formation among Japanese youth. Independent self formation is defined as any purposive action to form a self actively through individual efforts. This study provides evidence that the majority of Japanese youth, despite their culturally collectivist backgrounds, form selves individually at the level of specific activities. High levels of active self formation were found among 41% of the sample. These findings contribute to the literature on both self development and identity formation, with the finding that both independent self formation and proactive identity formation occur among a significant proportion of Japanese students. 相似文献
