Resumen
En la investigación de la neurociencia social,la modificación del parpadeo de sobresalto puede servir como un marcador de emoción, pero no es tan claro si también puede servir como un marcador de prejuicios. En el experimento 1, 30 estudiantes blancos vieron fotografías deobjetivos a blanco y Negro mientras se registraba el reflejo delparpadeo de sobresalto y las EMG faciales de las regiones de las cejas y las mejillas. El prejuicio se relacionó con la actividad EMG facial, pero no con la modificación de sobresalto, en cuyo lugar apareció la atención al índice de raza. A fin de probar si las categorizaciones raciales están asociadas con la atención diferencial, se utilizó un paradigma de doble tarea en el Experimento 2. 54 participantes blancos y 55 participantes negros respondieron más lento a un tono presentado al visualizar un miembro del grupo racial externo o de un estímulo negativo, lo que indica que ambos atraían más la atención que los miembros del mismo grupo o estímulos positivos. Llegamos a la conclusión de que la modificación de sobresalto es útil para indexar la atención diferencial a los grupos cuando la amenaza entre éstos es baja.
