    En dos experimentos se examina si el tamaño (3 y 15 grados de ángulo visual), duración de la exposición de los estímulos (10 y 200 mseg) interactúan en la determinación de la primacía del procesamiento utilizando estímulos en los que la posición retiniana de la información global y local es igual (Experimento 1) o diferente (Experimento 2). Los resultados muestran que la primacía global/local del procesamiento depende del tamaño y la posición retiniana de la información global y local. La duración de la exposición interactuó con el tamaño y la posición retiniana modulando los efectos de ventaja e interferencia de forma distinta en los dos experimentos.

    Two experiments are reported examining whether the size (3 and 15 degrees of visual angle) and exposure duration (10 and 200 msec) of stimuli interacted in determining global/local processing dominance using stimuli whit global and local levels located at the same (Experiment 1) or different retinal locus (Experiment 2). The results showed that global/local processing dominance depends on the size and eccentricity of global and local information. The exposure duration of stimuli modulated global/local dominance processing depending on both, the size of the stimuli and the same/different eccentricity of global and local information.
