The effect of aging on prospective memory was examined. Fifty older subjects and 69 college students were given measures of both retrospective memory and the Wood Prospective Memory Test. It was found that: 1) The reliability of the WPMT subscales was lower than that required for clinical applications; 2) The WPMT subscales correlated significantly with several measures of retrospective memory; 3) There was a tendency for the WPMT subscales to have low, positive but non-significant correlations with the remaining measures of retrospective memory; 4) A self-report questionnaire on prospective memory did not correlate significantly with measures of either prospective or retrospective memory; 5) The older subjects significantly outperformed the younger subjects on the WAISR Vocabulary subtest, but performed significantly more poorly on the WPMT subscales and almost all other measures.

Esta tesis doctoral pretende aportar nuevos datos sobre los efectos del enfoque AICLE (Aprendizaje Integrado de Contenido y Lengua Extranjera) en las habilidades productivas y receptivas de los alumnos de una escuela privada de Barcelona (Catalunya). Se trata de una comunidad bilingüe en la que las lenguas oficiales son el catalán y el español y en la que el inglés representa la tercera lengua del curriculum. Con este objetivo, se analizan longitudinalmente 100 alumnos bilingües catalán / español de edades comprendidas entre 12 y 15 a lo largo de dos años académicos en dos contextos de exposición diferentes: EFL (inglés sólo como asignatura de lengua extranjera, n=50, grupo de control) y AICLE (inglés como medio de instrucción cuando estudian ciencias naturales, n=50, grupo experimental). Se extraen datos a partir de las habilidades productivas y receptivas y se analizan de forma cuantitativa y cualitativa utilizando un diseño posttest al final de cada curso académico. Los resultados demuestran la efectividad del enfoque AICLE aunque no de forma generalizada en todas las habilidades. A diferencia de investigaciones anteriores, es importante destacar la mejora de la corrección dentro de la producción escrita y de las habilidades léxico-gramaticales. Finalmente, los resultados tienden a confirmar que el factor edad es relevante y que obtienen mejores resultados los sujetos mayores. / The present study seeks to contribute new evidence on the effects of the CLIL approach (Content and Language Integrated Learning) on the learners’ productive and receptive skills in a private school in Barcelona (Catalonia). This is a bilingual community in which both Catalan and Spanish are official languages and where English represents the third language included in the currículum. For that purpose, 100 bilingual Catalan / Spanish students aged 12 to 15 are analysed longitudinally over two academic years in two different types of exposure contexts: EFL (English only as a foreign language school subject, n=50, control group) and CLIL (English as medium of instruction when learning Science, n=50, experimental group). Data are elicited both for productive and comprehension skills and are analysed quantitatively and qualitatively using a posttest design at the end of each academic year. The results show the effectiveness of the CLIL approach, however not in all skills. In contrast with findings published in previous studies, the subjects’ writing and particularly so accuracy, significatively progressed and so did lexico-grammatical abilities.Results also tend to confirm that age had an impact and thus the older, the better.
