Resumen
El Paradigma de la Señal de Parar es uno de los procedimientos más utilizados para la medición del control inhibitorio, debido a que proporciona un índice no accesible a través del uso de otros paradigmas: el "tiempo de frenado" o tiempo que se necesita para inhibir una respuesta. El método utilizado para el cálculo de esta medida se sustenta en los supuestos principales de un modelo de inhibición: el "Modelo de Carrera de Caballos". Sin embargo, su difusión es limitada, debido a la escasa bibliografía disponible en español y a la complejidad de sus análisis matemáticos. Por ello, se presenta la descripción del modelo y la explicación del método utilizado para la estimación del tiempo de frenado: el procedimiento de ajuste dinámico. Esto contribuirá a difundir el paradigma en nuestro medio, a discriminarlo de otros y a facilitar la interpretación de sus resultados.
The Stop Signal Paradigm is one of the most used procedures for measuring the inhibitory control. Their widespread diffusion is due to two reasons: its extensive application in the field of clinical neuropsychology and because it provides an index-braking time-that is not accessible with other paradigms or procedures. This index is defined as the time required for inhibiting a dominant response. The method used to calculate this measure is based on a classical model of inhibition: the “Horse Race Model”. However, their diffusion is limited in our environment because the available literature in Spanish is poor due to the complexity of mathematical analysis involved. Therefore, the aim of this work is to carry out a review of this method and present some of its applications in the field of clinical neuropsychology and psychopathology, such as working with patients with obsessive compulsive disorder, addictions, and attention disorder, among others.
