El presente estudio investigó las características de la memoria táctil de trabajo utilizando la Tarea N-Back. Los participantes (n = 16), todos videntes, realizaron la tarea con cargas equivalentes a una, dos o tres letras en la memoria de trabajo (N-Back 1, N-Back 2 y N-Back 3). Los errores de comisión y omisión se analizó de acuerdo con la carga de trabajo. Los resultados indican un aumento en la frecuencia de errores de omisión debido a este factor. Las comisiones no fueron influenciadas significativamente por la carga de memoria de trabajo. En general, nuestros resultados sugieren que la tarea N-Back táctil puede representar un método prometedor para la evaluación de la memoria de trabajo en participantes videntes y no videntes.
