ResumenEl presente estudio intenta analizar, desde una perspectiva psicolinguistica, el desarrollo fonológico de niños castellanoparlantes de la ciudad de Málaga, en función de variables como el sexo, el nivel sociocultural y edad de los sujetos, atendiendo, por otra parte, a la influencia de características dialectales del habla andaluza.Tras la elaboración y administración de una prueba de screening, en condiciones de imitación, se registraron las producciones correctas y distintos procesos de simplificación del habla (sustitución, relativos a la estructura de la sílaba y asimilatorios), no encontrándose diferencias significativas con respecto al sexo, aunque sí en cuanto al nivel sociocultural y a la edad de los sujetos.Cabe destacar que la influencia del modelo lingüístico andaluz podría enmascarar los patrones evolutivos del desarrollo fonológico infantil. Sin embargo, el hecho de que los sujetos malagueños presenten porcentajes bajos en pronunciación correcta en edades avanzadas, en algunas categorías de fonemas, es debido a la influencia de variantes dialectales, más a que presenten patrones evolutivos más tardíos en cuanto a su capacidad de representación fonológica. 相似文献

Autism spectrum disorders (ASD) are pervasive neurodevelopmental disorders that affect an estimated 1 in 110 individuals. Although there is a strong genetic component associated with these disorders, this review focuses on the multifactorial nature of ASD and how different genome‐wide (genomic) approaches contribute to our understanding of autism. Emphasis is placed on the need to study defined ASD phenotypes as well as to integrate large‐scale “omics” data in order to develop a “systems‐level” perspective of ASD, which in turn is necessary to allow predictions regarding responses to specific perturbations and interventions. 相似文献

This short report describes an evaluation of the instrument used for the selection of future police officers in Scotland – the Standard Entrance Test (SET). The study was commissioned by the Scottish Office and undertaken by the Scottish Council for Research in Education during 1995–6. The authors outline the project, report their main findings and identify groups which may have been disadvantaged. The outcome, a revised test, is currently being piloted with new entrants to the force. 相似文献

In order to test the hypothesis that genetic influences are moreimportant as a cause of reading disability in girls than in boys,composite reading performance data from identical and fraternal twinpairs were analyzed using both concordance and multiple regressionmethods. The sample included 206 identical (99 male, 107 female), 159same-sex fraternal (90 male, 69 female), and 117 opposite-sex fraternaltwin pairs, in which at least one member of each pair had readingdifficulties. Although the difference between the concordance rates forreading disabilities in female identical and same-sex fraternal twinpairs was somewhat greater (65% for identical twins vs.32% for fraternal twins) than the difference in concordance ratesfor boys (68% vs. 39%), loglinear analysis of thesecategorical data revealed that the interaction between sex, zygosity,and concordance was not significant (p > 0.70). Moreover,the heritability of reading disability(h
2
g) estimated from regression analysisof the reading performance data in males was nearly identical to that infemales (h
2
g = 0.58 and 0.59,respectively; p > 0.90). Thus, results of this studyprovide little or no evidence for the hypothesis of greater geneticinfluence on reading difficulties in girls than in boys. 相似文献

In the Netherlands, many women have entered the labor market in the last two decades. This development - among other social changes - has resulted in substantial shifts in the time that Dutch people spend on paid labor and "caring tasks" on the one hand and leisure activities on the other hand. This task combination has caused serious time pressure and coordination problems among dual-income families with children. Therefore, it is not an exaggeration to label this stage of life as the "rush hour of life". In this article the findings of a small-scale qualitative case study among these "busy" households are presented. The objective of this study is to describe and analyze patterns of acceptance and use of information and communication technologies (ICTs), especially telecommunication technologies, in the context of the everyday life of these households. The question is raised whether ICTs can be a solution to time pressure and coordination problems. Theoretically, the research is rooted in a user-oriented perspective toward technological innovation, developed in the United Kingdom by Silverstone, Haddon, and others, which understands the incorporation of ICTs into the everyday life of households as a "domestication process". A paradoxical conclusion of this study is that ICTs are not explicitly perceived as solutions to the communication and coordination problems these households experience in everyday life, although they are being used for solving these problems. This ambiguity seems characteristic for the acceptance of ICTs in everyday life. The domestication concept is a useful concept to describe these ambivalent and paradoxical processes of (non)acceptance and use. 相似文献

We examined Nonsense-Passage oral reading in adults, using data derived from new and previously published studies (Finucci et al 1976, Gross-Glenn et al 1985). Time-scores and error-frequency data are presented for five samples of non-dyslexic readers with a minimum of a high-school education and no childhood history of dyslexia (N=127). Considerable uniformity is demonstrated across these samples, and reading performance of non-dyslexic individuals contrasts sharply with that observed in four samples of adult familial dyslexics. Both affected and compensated-affected dyslexic subjects read the passages significantly more slowly and with more errors than did nondyslexic readers. Results are discussed in relation to the cognitive and neural processes that may underlie this specific reading difficulty in dyslexics. We have found Nonsense-Passage reading to be especially useful in family studies of inherited dyslexia as a means of quantifying oral reading deficits in adults who have learned to compensate for their children reading difficulties. 相似文献

The present study assesses the genetic and environmental etiologies of reading, rapid naming (RN), and their covariation by
fitting multivariate structural equation models to data from 587 twin pairs in which at least one member of the pair exhibited
reading difficulties (low-range) and from 360 control (normal-range) twin pairs who were tested in the Colorado Learning Disabilities
Research Center. Results from a bivariate phenotypic analysis with two hypothesized latent factors, READ and RN, indicated
that the correlation between reading and rapid naming performance for the low-range sample was significantly higher than that
of the normal-range sample. When this model was partitioned to include estimates of genetic, shared environmental, and nonshared
environmental influences, resulting heritability estimates did not differ significantly for the low-range and normal-range
samples for either READ or RN. However, similar to the phenotypic correlation, the genetic correlation between the READ and
RN latent factors could not be equated for the two groups. Thus, the etiology of the relationship between reading performance
and rapid naming may differ for children with reading difficulties and normally-achieving readers. Moreover, these results
support previous findings that the best predictors of reading skills may differ for samples of children with normal reading
levels and those with reading difficulties. 相似文献
