This study investigated whether or not the temporal information encoded in aspectual morphemes can be used immediately by young children to facilitate event recognition during online sentence comprehension. We focused on the contrast between two grammatical aspectual morphemes in Mandarin Chinese, the perfective morpheme –le and the (imperfective) durative morpheme –zhe. The perfective morpheme –le is often used to indicate that an event has been completed, whereas the durative morpheme –zhe indicates that an event is still in progress or continuing. We were interested to see whether young children are able to use the temporal reference encoded in the two aspectual morphemes (i.e., completed versus ongoing) as rapidly as adults to facilitate event recognition during online sentence comprehension. Using the visual world eye-tracking paradigm, we tested 34 Mandarin-speaking adults and 99 Mandarin-speaking children (35 three-year-olds, 32 four-year-olds and 32 five-year-olds). On each trial, participants were presented with spoken sentences containing either of the two aspectual morphemes while viewing a visual image containing two pictures, one representing a completed event and one representing an ongoing event. Participants’ eye movements were recorded from the onset of the spoken sentences. The results show that both the adults and the three age groups of children exhibited a facilitatory effect trigged by the aspectual morpheme: hearing the perfective morpheme –le triggered more eye movements to the completed event area, whereas hearing the durative morpheme –zhe triggered more eye movements to the ongoing event area. This effect occurred immediately after the onset of the aspectual morpheme, both for the adults and the three groups of children. This is evidence that young children are able to use the temporal information encoded in aspectual morphemes as rapidly as adults to facilitate event recognition. Children’s eye movement patterns reflect a rapid mapping of grammatical aspect onto the temporal structures of events depicted in the visual scene. 相似文献

Early Maladaptive Schemas (EMS) are described as long‐held core beliefs which are dysfunctional to a significant degree. However, the supposition that schemas are dysfunctional by nature, while not isomorphic with psychiatric syndromes, is yet to be subjected to empirical review. The current study seeks to investigate the relationship between the Young Schema Questionnaire and the concept of ‘dysfunction’ in a community sample to determine the indirect effects of psychiatric symptomatology and validate current scoring guidelines with a convergent measure of dysfunction. A total of 464 people completed a survey online comprising of the YSQ‐Short Form, the Depression, Anxiety and Stress Scales‐21, the Social and Occupational Functioning Assessment Scales, and the World Health Organization Quality of Life Scale. Multiple regression analyses revealed a moderate relationship between EMS categories and measures of dysfunction, however only six of eighteen EMS categories were significant predictors in this model. Mediation analyses further suggest that the relationship between EMS and dysfunction is partially mediated by psychiatric symptomatology. The current dichotomous clinical scoring guidelines were found to be invalid when measures of functioning were used as convergent measures for twelve of the EMS categories. These findings suggest the YSQ is best conceptualised as a general measure of schema as opposed to a measure of EMS categories. 相似文献

Fifty nine premature infants participated in a randomized controlled study to determine the effectiveness of non-nutritive sucking (NNS). It was predicted that NNS would not accelerate the development of full oral feeding or early language skills as sometimes perceived in practice. However, it was predicted that using NNS as a strategy to support parents to identify and respond to early communication and oral readiness signs would increase confidence in infant management and enable quicker discharge home. Infants were aged 26–35 weeks gestation. Infants with no significant difficulties were randomly assigned to one of three groups; Group 1, NNS pre-tube feeding (n = 19); Group 2, NNS on onset of tube feeding (n = 20) and Group 3, Control (n = 20). Follow-up occurred at 6 months. There were no significant differences with number of days to full oral feeding between the groups receiving NNS and the Control group, χ2(2, n = 59) = 4.33, p = .115. A significant difference in number of days in hospital between the Control group and the other two groups was found χ2 (2, n = 59) = 7.678, p = .022. Significant changes were noted with the development of more normal sucking patterns in Groups 1–3. At 6 months there were no significant differences in receptive or expressive language skills between all groups. NNS had no significant impact on the transition to full oral feeding or later language development. There was a significant difference in the number of days in hospital between the Control group and the other two groups which involved parents in identification of early communication signs. Possible reasons for this change and future directions are discussed. 相似文献

The Work Design Questionnaire (Morgeson & Humphrey, 2006) assesses numerous work characteristics. The present research was designed to assess the psychometric properties of a French version of this tool (i.e., WDQ-F) through the following analyses: confirmatory factor analysis, reliability, and nomological validity with work satisfaction, engagement and burnout. In Studies 1 and 2, results of confirmatory factor analyses showed that the fit indices for the 21-dimension model were poor and that seven items displayed low factor loadings. In Study 2, results showed that a reduced version of the WDQ-F (71 items) demonstrated better psychometric properties than the 77-item version of the questionnaire. In addition, correlation analyses provided support for the nomological validity of the WDQ-F. 相似文献

AimTo establish the psychometric properties of a newly developed screening tool Screening Solid Foods Infants 1 (SSFI-1) used by early childhood professionals, to detect problems in the transition from milk to solid food of smooth consistency in infants 6–9 months of age.MethodsThe SSFI-1 score was filled out by the parents of a subgroup with term infants (n = 35); healthy preterm infants (n = 26); infants with comorbidity (n = 17); infants with feeding problems (n = 13). Internal consistency, reproducibility, construct, criterion and related validity was evaluated.ResultsThe preterm subgroup differed significantly in age when starting with fruits/vegetables and period of experience (p < 0.01). The SSFI-1 was sufficiently reliable for the total group and term subgroup (α = 0.78 and 0.76), but not for the preterm and comorbidity/feeding problem subgroup (α = 0.51 and 0.69). Inter-rater reliability was high for the total score (n = 25, ICC r = 0.93), and moderate to good for individual items (weighted kappa range 0.55–0.95). Validity was confirmed by significantly higher scores for the comorbidity/feeding problem subgroups and clinically distinguishable subgroups (p < 0.05) and area under the curve values > 0.78. The initial 10-item screening tool was modified to a seven item screening tool. A SSFI-1 score of 4, +2 SD of the term subgroup, had 76.9% sensitivity and 82.1% specificity, for detecting the presence of a feeding problem.ConclusionThe seven-item screening tool Screening Solid Foods 1 may be used as a screening tool for term infants. Further testing of the SSFI-1 in new infants is needed, to confirm reliability and validity both for term, preterm and (risk for) feeding problem infants. 相似文献

Productivity is a central concept in the study of language and language acquisition. As a test case for exploring the notion of productivity, we focus on the noun slots of verb frames, such as __want__, __see__, and __get__. We develop a novel combination of measures designed to assess both the flexibility and creativity of use in these slots. We do so using a rigorously controlled sample of child speech and child directed speech from three English‐speaking children between the ages of 2–3 years and their caregivers. We find different levels of creativity and flexibility between the adult and child samples for some measures, for some slots, and for some developmental periods. We discuss these differences in the context of verb frame semantics, conventionality versus creativity and child errors, and draw some tentative conclusions regarding developmental changes in children's early grammatical representations. 相似文献
