Effects of Intergenerational Interaction on Aging

The world population pyramid has changed shape. However, this does not mean that societies have changed their negative concept of old age. Our study proposes an intergenerational service-learning program with 179 university students and 101 slightly depressed elderly people. The results show that the elderly people who interacted improved in well-being. Those interacting with the young people tended to lower their stereotyped perception of themselves, while the others tended to augment it. The young people tended to moderate their stereotypes of the elderly with or without interaction.

Variables de Medida para el Razonamiento Deductivo

espanolHay doble pulsion en el centro de la discusion del razonamiento deductivo. Una conduce aparentemente a la abstraccion y dominios arbitrarios, mientras que la otra conduce a la concrecion y la dependencia del contenido. El objetivo de esta investigacion es disenar, aplicar y validar un instrumento de evaluacion que nos permita corroborar si el razonamiento deductivo maneja reglas logicas o contenidos. La muestra de estudio se compuso de 80 participantes (edad 18 - 77 anos). El test consta de 6 0 items categorizados en: formalidad, integrabilidad, complejidad y modalidad. Los resultados ponen de manifiesto la fiabilidad del test de razonamiento deductivo con un alpha de Cronbach .775 y con un indice de validacion .850 para el indice de inteligenc ia no verbal (INV) del RIAS. Como conclusion inferimos que el razonador deductivo no dispone de un cuerpo preciso de reglas generales deductivas, sino que usa colecciones de reglas heuristicas cada vez menos abstractas. EnglishThere is a double drive at the center of the discussion on deductive reasoning. One seems to lead to abstraction and domain independency, while another leads to concretion a nd content dependency. The objective of this research is to design, apply and validate an evaluation instrument that allows us to corroborate whether deductive reasoning handles logical or content rules. The sample consisted of 80 participants aged among 1 8 and 77 years. The test consists of 60 items categorized in levels of formality, integrability, complexity and modality. The results demonstrate the reliability of the deductive reasoning test with a Cronbach alpha of .775 and a validation index of .850 t o the non - verbal intelligence index (INV) of RIAS. As a conclusion we infer that tested deductive reasoners lack a definite corpus of general deductive rules, and on the contrary they use collections of decreasingly abstract heuristic rules.
