Abstract
Los modelos de variables latentes y los modelos cognitivos formales comparten algunos aspectos de su objeto de estudio, varios aspectos filosóficos y parte de su metodología. A pesar de ello, existe poca comunicación entre sus teorías y hallazgos. Con el objetivo de resaltar similitudes y diferencias entre ambos enfoques en este estudio se implementó y evaluó un modelo formal que propone la interferencia entre representaciones como el mecanismo que limita la capacidad de memoria de trabajo (i.e., el modelo de interferencia de Oberauer & Kliegl, 2006). Además, se incorporó una manipulación experimental que tuvo como objetivo evaluar el papel de la inhibición en respuestas inminentes y el desplazamiento de la atención entre tareas en el contexto del modelo de interferencia. A partir de estos hallazgos se expusieron algunas conexiones que podrían facilitar el acercamiento entre los modelos cognitivos formales y los modelos psicométricos basados en la teoría de la variable latente.
Latent variable models and formal cognitive models share some elements of their object of study, various philosophical aspects, and some parts of their methodology. Nevertheless, little communication exists between their theories and findings. In order to highlight similarities and differences, this study implemented and tested a formal model proposing that interference among representations is a mechanism limiting working memory capacity (i.e., the interference model of Oberauer & Kliegl, 2006). Furthermore, the study incorporated an experimental manipulation to evaluate the role of the inhibition in prepotent responses and task switching in the interference model framework. These findings were used to expose some connections that could facilitate a rapprochement between formal cognitive models and psychometric models based on the latent variable theory.
