Esta investigación ha tenido como objetivo comparar la amplitud de aprehensión de dos grupos de pacientes esquizofrénicos (paranoide y no-paranoide) y la de un grupo de sujetos normales. Las variables independientes han sido la duración de la exposición y el número de items. Los resultados sugieren que los esquizofrénicos procesan la información visual menos eficientemente que los normales.
