Resumen

Debido al interés que tiene en el campo aplicado, se ha investigado mucho sobre la relación entre la confianza de un testigo y la exactitud de sus recuerdos. Los expertos en memoria de testigos comparten la idea de que la confianza manifestada por los testigos en su testimonio predice su exactitud. A pesar de la validez aparente de la confianza, distintos meta-análisis sobre identificación de personas demuestran una baja validez predictiva. También se ha comprobado que determinadas situaciones favorecen la relación confianza-exactitud y otras la inhiben. En las tareas de testimonio los resultados encontrados son contradictorios, tal vez debido a las diferencias metodológicas de los estudios en cuanto al nivel de dificultad de los ítems, el tipo de información que contienen o la prueba de evaluación de memoria.
