The permittivity and the dielectric loss of ternary mixtures of equimolar concentrations of m-cresol, o-cresol with acetonitrile, acrylonitrile and benzonitrile in benzene have been measured at 8.33 GHz and 308 K. The distribution parameter α, the most probable relaxation time τ, the relaxation time for overall rotation of the molecule τ(1), the relaxation time for group rotation τ(2), and the excess dipole moment for various systems have been calculated by the Cole-Cole and Higasi methods. Data has been analyzed in terms of two-relaxation processes: overall rotation and group rotation.  相似文献

The purpose of this study was to determine whether cross-sectional and growth effects in second language (L2) literacy are related to the executive component of working memory (WM) and whether inhibition may underlie the links between WM and reading in children whose first language (L1) is Spanish. Elementary school children (grades 1, 2 and 3) were administered a battery of cognitive [WM, short-term memory (STM), random generation, rapid naming, phonological processing], vocabulary and reading measures in both Spanish (L1) and English (L2) in Year 1 and again one year later. The regression analyses showed that L2 growth in WM significantly predicted growth in L2 reading skills even when inhibition was controlled. Further, the contributions of WM to reading growth in both L1 and L2 reading were independent of cross-language skills in phonological processing, STM, oral language and naming speed. Overall, the results suggest the mental activities that underlie WM and inhibition in predictions of L2 literacy reflect independent executive processes.  相似文献

ABSTRACT

A large body of research shows that performing tests is more beneficial for the retention of studied materials than restudying those materials, a phenomenon termed “testing-effect”. A contemporary debate on the testing effect literature concerns whether the benefits of tests are equivalent for individuals with different cognitive skills, as the capacity to decode written words, for example. In the current study, we approached this issue in two experiments by examining whether testing is equally beneficial for children with diverse visual word decoding skills. To achieve this goal, we recruited sixth and fourth grade children (experiments 1 and 2, respectively) and administered a reading aloud task to assess their visual word recognition skills, and administered a memory task about an encyclopedic text to promote the testing effect. Memory for the restudied/tested contents of the encyclopedic text were probed after a seven-day interval, and although children from both experiments showed robust testing effects, such effects were not associated with their visual word decoding skills. These findings suggest that children with diverse word decoding skills can be benefited by retrieval practice.  相似文献

ABSTRACT

Despite the huge interest in different philosophical questions surrounding literature, particularly analytic philosophers have had relatively little to say about literature’s specifically aesthetic character. Peter Kivy has developed this antiaesthetic tendency furthest, ultimately denying that the reading of prose literature has any deep aesthetic content. Building on Alan Goldman’s and John Dewey’s work on aesthetic experience, I argue that a key literary feature of novels I single out – what I term a replete moment – has the potential to trigger in readers significant aesthetic experiences. Along with revealing aesthetic aspects in reading that Kivy’s position does not cover, my account shows that contemplation of the overall structure of the novel is not the sole, more substantial form aesthetic experience can take in the case of reading, as Kivy’s formalistic literary aesthetics assumes. This conclusion is argued to be significant also for the general philosophical discussion on aesthetic experience. An analysis of a key passage in John Irving’s A Prayer for Owen Meany is an important part of the view of literary aesthetic experience put forth.  相似文献

Perceived organizational support plays an important role in the social exchange relationship between the employee and the organization. We propose that individual differences in collectivism affect the extent to which employee–organization relationships are based on social exchange, and that therefore collectivism moderates the relationship between perceived organizational support and organizational citizenship behaviour. Results of a survey (N = 293) assessing perceived organizational support, collectivism, and supervisor ratings of organizational citizenship behaviour supported this hypothesis. We conclude that organizational citizenship behaviour originates from social exchange processes only among employees who construe the self in relatively individualistic terms.  相似文献

In the present study, the relationship between self-reports and objective measures of health status and measures of cognitive performance was examined. Participants consisted of 437 persons (M =72.91 years) from the Charlotte County Healthy Aging Study, a population-based sample of older adults. Cognitive performance was assessed by tests of episodic memory, perceptual speed, and attention. Health status was indexed by subjective ratings, self-reports, and objective measures. The health measures accounted for significant variance on both the Trailmaking A and B tests, accounting for a modest amount of variance (4.4% and 1.1%, respectively). The health measures were not significantly associated with performance on the measures of attention or episodic memory. The results suggest that health status is associated with processing speed to a greater degree than higher order cognitive processes.  相似文献

The opposition between behaviour- and mind-reading accounts of data on infants and non-human primates could be less dramatic than has been thought up to now. In this paper, I argue for this thesis by analysing a possible neuro-computational explanation of early mind-reading, based on a mechanism of associative generalization which is apt to implement the notion of mental states as intervening variables proposed by Andrew Whiten. This account allows capturing important continuities between behaviour-reading and mind-reading, insofar as both are supposed to be just different kinds of generalization from perceptual experience. Specifically, I will argue that the projection of inner experiences to others which is involved in early mind-reading does not imply a computational leap beyond associative generalization from perceptual experience.  相似文献

The authors attempted to develop and validate the Toddler Attention Questionnaire (TAQ) by examining the relationship between attention and attachment to a professional caregiver. The psychometric reliability and validity of the TAQ was tested with 72 children ranging from 20 to 36 months old. Attentive processes were also measured by the Italian Questionnaire on Temperament, while attachment behaviors to professional caregivers were measured by the Attachment Q-Sort. Factor analysis supported four identifiable factors reflecting different concepts, theoretically discussed, related to attentive processes: attentive flexibility, attentive lability, attentive detachment, and attentive disorientation. Attachment security to professional caregivers is predicted through attentive flexibility and negative emotionality. Secure attachment behaviors were found to be related to flexibility of attention. The implications of the findings for future theoretical and empirical development of research in this field are also discussed.  相似文献
