Extinction context as a conditioned inhibitor

Two lick suppression experiments using rats were conducted to determine whether extinction of a punctate excitor in a particular context would result in that context becoming a conditioned inhibitor, as defined by passing both summation and retardation tests. The role of extinction trial spacing was investigated as a possible determinant of whether the extinction context would become inhibitory. Experiment 1 demonstrated that, although inhibition was evident using either massed or spaced extinction trials, spaced trials reduced measurable inhibition as assessed by the summation test, but trial spacing had no influence on retardation test performance. Experiment 2 confirmed Experiment 1’s conclusions while controlling for the influence of latent inhibition on the retardation test. In Experiment 2, the context proved inhibitory only following massed extinction trials. These data suggest that, at least with select parameters, an extinction context can become inhibitory.     

Estudio comparativo de la evaluación de la lectura oral y la lectura silenciosa

Resumen

El propósito de este trabajo es comparar los procesos implicados en la lectura oral y en la lectura silenciosa, teniendo en cuenta factores tales como la edad de los sujetos, (se trabaja con individuos de 2.°, 4.° y 6.° cursos de E. G. B.), y el propósito o intención con la que se lee. Se emplean tests tipo «cloze», en los que los sujetos tienen que completar (predecir) los espacios en blanco del texto. Las puntuaciones se obtienen del análisis de los errores cometidos en ambos tipos de lectura, según un método derivado del de Goodman y Burke (1973); como medidas se toman la comprensión lectora y la velocidad de lectura. Por último, se ofrecen una serie de conclusiones respecto a los tipos de lectura, respecto al procedimiento de evaluación y respecto a las medidas utilizadas.     

El adolescente como historiador

Resumen

Este articulo presenta una investigación sobre el desarrollo del pensamiento hipótético-deductivo en tareas históricas. Se trata de una habilidad fundamental para dominar situaciones históricas complejas, tan frecuentes en los libros de texto. Los resultados muestran un escaso dominio de esta habilidad por parte de los adolescentes. Se analizan las causas y las implicaciones educativas de esta falta de pensamiento histórico científico.     

Aportaciones de la psicología cognitiva y de la instrucción a la enseñanza de la Historia y las Ciencias sociales

Resumen

Este artículo presenta una visión general de las aportaciones de la investigación cognitiva e instruccional al estudio de la enseñanza de la Historia y las Ciencias Sociales. En primer lugar se indican algunas de las relaciones entre Psicología y Didáctica. Posteriormente se incluye un panorama general de la investigación sobre la comprensión y aprendizaje de las Ciencias Sociales y la Historia. Se comentan algunos trabajos pioneros de Dewey y Piaget y se discuten las críticas que han recibido los trabajos piagetianos de los años sesenta y setenta sobre este tema. Por último, se discuten los principales problemas de esta área de investigación. Es decir, lo concerniente a. la comprensión y aprendizaje de los conceptos, tiempo y casualidad histórica y al relativismo cognitivo. Las implicaciones instruccionales de este tipo de investigaciones son discutidas en relación con algunos de los más importantes problemas epistemológicos de la Historia en la actualidad.     

On the use of extended TAM to assess students' acceptance and intent to use third‐generation learning management systems

Service‐oriented e‐learning platforms can be considered as a third generation of learning management systems (LMSs). As opposed to the previous generations, consisting of ad hoc solutions and traditional LMS, this new technology contemplates e‐learning systems as services that can be integrated into different learning scenarios. This paper shows that the flexibility of these systems allows building personal learning environments and proposes the use of an extended technology acceptance model (TAM) to assess the acceptance and intention to use a third generation of LMS. To fit and validate the service‐oriented e‐learning platforms acceptance model, structural equation modeling and path analysis have been implemented. The results point out that the intention to use this third‐generation LMS is determined by the gadgets and container design, both of which are structural elements of this technology. Finally, it is also shown that previous experience does not determine the use intention of this technology.     

Discriminant analysis of anthropometric and biomotor variables among elite adolescent female athletes in four sports

The aim of this study was to identify anthropometric and biomotor variables that discriminated among groups of elite adolescent female athletes aged 14.3 ± 1.3 years (mean ± s) from four different sports (tennis, n = 15; swimming, n = 23; figure skating, n = 46; volleyball, n = 16). The anthropometric variables included body mass, height, bi-epicondylar breadth of the distal extremity of the humerus and femur, maximal girth of the calf and biceps and the sum of five adipose skinfolds. The biomotor variables were maximal aerobic power, muscular endurance and flexibility of the trunk. Discriminant analysis revealed three significant functions (P ? 0.05). The first discriminant function primarily represented differences between figure skaters and all other groups of athletes. The other two underlined anthropometric and biomotor differences between swimmers and volleyball players and between tennis players and swimmers, respectively. After validation, the analysis showed that 88% of the athletes were correctly classified in their respective sports. Our model confirms that elite adolescent female athletes show physical and biomotor differences that clearly distinguish them according to their particular sport.

Patterns of Close Relationships and Socioemotional and Academic Adjustment Among School‐Age Children with Learning Disabilities

This study examined patterns of close relationships among school‐age children with learning disabilities (LD) as manifested in their attachment style, their self‐perceived loneliness, their sense of coherence, and teacher ratings of their academic functioning. In line with resilience theory, this study also aimed to further explore predictors of positive adjustment for children with LD. The sample comprised 98 children with LD from regular classes in four Israeli public elementary schools, and 98 non‐LD children from the same classes. Significant group differences emerged in attachment styles and adjustment. Attachment style significantly correlated with socioemotional adjustment but not with academic functioning. In addition, a subgroup of resilient children emerged among the LD children. Discussion focused on the value of attachment patterns for understanding social and emotional adjustment among school‐age children with LD.
