Reflexiones sobre el lenguaje autista. I.—Análisis descrpitivos y diferencias con la disfasia receptiva

Resumen

En este articulo, se revisan las descripciones clínicas y los estudios sistemáticos que tratan de establecer los rasgos que definen al lenguaje de los autistas cuando se les compara con el dé los sujetos normales o con otras clases de alteraciones. En la última parte de él, se analizan especialmente las semejanzas y diferencias entre el lenguaje autista y el de los niños con disfasia receptiva del desarrollo y anlizaremos la llamada «tesis de continuidad», que concibe el autismo como una especie de disfasia receptiva grave. En un trabajo posterior, se analizarán más específicamente algunas de las alteraciones más características del lenguaje de los autistas (p.e. ecolalia, inversión pronominal, problemas de comprensión) y se discutirán sus anomalías y retrasos en relación con los distintos componentes (fonológico, morfosintáctico, léxico, etc.) en que puede analizarse el lenguaje.     

Clase social y situación dentro de la fratria: Interacción y efectos sobre el desarrollo del individuo

Resumen

En este estudio se analiza la influencia de la clase social, el número de hermanos y el orden de nacimiento sobre una serie de variables cognitivas y de rendimiento escolar.

Se ha realizado la investigación sobre una muestra de 507 alumnos de 1° de E.G.B., pertenecientes a los Centros Públicos de Valladolid y provincia. Las variables de rendimiento escolar se evaluaron a través de la opinión del profesor. La valoración, en cambio, de las cognitivas se realizó por medio de pruebas estandarizadas. Dentro de los efectos principales, y dejando aparte las diferencias marcadas por el medio social, obviamente esperadas, destacamos una fuerte influencia del orden de nacimiento sobre prácticamente todas las variables dependientes. Su interacción con la variable socio cultural es el resultado más destacable del presente trabajo. Dedujimos como hipótesis explicativa las diferentes pautas culturales que propician o no la estabilidad de los patrones educativos familiares.     

Variables involved in personal, social and school adjustment in a sample of preschool-aged children from different cultural backgrounds

The continuing incorporation of immigrant populations into the Spanish educational system poses an important challenge in that all participants must cooperate toward creating the best possible adaptation process at the academic level as well as on the personal and social levels. A number of different factors appear to influence children’s adjustment during the preschool stage, and these factors are especially relevant since many studies have shown that this is a key period for the prevention of future difficulties. The present study examines the variables involved in the adaptation of a group of preschool-aged children from different cultural backgrounds in Spain. The results indicate that preschoolers, regardless of their background, have similar performance and learning potential, with language proficiency being the factor that most clearly affects the other variables investigated. It was also found that children’s attitudes toward learning were related to the presence of behavioral difficulties and with the quality and type of parental child-rearing practices. These practices appear to be related to a number of difficulties immigrant children may experience on personal and social levels.     

Effect of dual-attention task on attack and defensive actions in fencing

The objectives of this study were to investigate the effect that the presence of two stimuli that require two different responses (dual-attention) has both, on offensive reaction-response time to a light stimulus, and on defensive response time when the stimulus is a real fencing attack. Twenty-five elite fencers and a fencing master were included in the study. The equipment included four force plates adapted to a scaffold that served as a fencing piste. Two force plates were placed, at the start position, under the fencer’s feet and another two plates were placed under the master’s feet. The results demonstrate that choice reaction time to visual stimuli increases in dual-task conditions with respect to simple reaction time, whereas the mean horizontal force tends to decrease in dual-task. However, when the stimulus was an opponent’s movement, dual-task conditions did not have any effect on the time required to initiate a defensive action. The changes in reaction time when real movements were used as stimuli challenge the validity of the reaction time to visual stimuli paradigm as a predictor of performance in fencing. Also, the results obtained demonstrate that perceptual and attentional processes play a major role in fencer performance in real competition.

大学治理:责任与财政

大学的演变主要体现在大学的结构、治理、管理系统、拨款机制方面以及知识、形式与内容的多样化。大学在公众参与和权威主义方面已经从一个极端走向了另一个极端。大学的未来取决于社会的引导和内部的共生。高等教育已经从以学习者为中心转向以教学和管理人员的共生结构为中心,高等教育经费需要多样化的渠道。大学的持续变革对于学校内部机制的公平、效力、效率、相关性,以及学生、教授、研究者和管理者等大学成员的道德规范提出了要求。     

Using ePortfolios to Assess Student Achievement within an Online Library and Information Studies Program

As a result of suggestions from the American Library Association (ALA) the Division of Library and Information Science (DLIS) program at St. John's University implemented an end-of-program electronic portfolio (ePortfolio) requirement. The purpose of this ePortfolio is to provide information on student proficiency in the eight ALA core competencies to our external accrediting agency—the ALA Committee on Accreditation (CoA). This article will discuss how a Library and Information Studies (LIS) faculty member and a New Media and Communications Specialist worked together in developing the ePortfolio as an assessment tool for ALA reaccreditation within an online LIS program.     

The effective use of student time: a stochastic frontier production function case study

The relationship between student study time allocation and examination performance is little understood. We model the allocation of student time into formal study (lectures and classes) and self study and its relationship to university examination scores using a stochastic frontier production function. This case study uses unique time budget data and detailed personal records from one university in Spain. The results suggest that, within the formal system of teaching in Spain, both formal study and self study are significant determinants of exam scores but that the former may be up to four times more important than the latter. We also find that self study time may be insignificant if ability bias is corrected for.
