• Resumen

  • Aunque el fenómeno de la amnesia posthipnótica se ha invocado en diferentes contextos, su situación académica aún está poco clara. Este estudio examina la asunción exagerada de que la amnesia hipnótica y la amnesia debida a una lesión cerebral comparten similitudes en la memoria implícita. Se compararon sujetos sugestionables, que recibieron una sugestión de amnesia, con un grupo control que no recibió intervención y un grupo de simulación en dos pruebas de memoria, finalización de fragmentos y el test de la moneda en la mano. Ya que los pacientes con lesiones cerebrales generalmente realizan mejor estas pruebas que los simuladores, se ha propuesto que estas pruebas pueden ser útilespara la detección de fingimiento en el contexto clínico. En ambos tests, los participantes de alta y media susceptibilidad hipnótica, mostraron semejanzas con los simuladores, manifestando déficits en la memoria implícita que no es habitual en los pacientes con lesiones cerebrales. Se concluye que estos resultados son acordes con una supresión de la respuesta informada en la amnesia hipnótica.
