Abstract

El objetivo del presente trabajo consistió en analizar la capacidad de personas con discapacidad intelectual ligera y moderada para identificar a personas desconocidas vistas durante un periodo de tiempo breve y evaluar los factores que pudieran facilitar la tarea minimizando los errores. Para ello, se presentó a dos grupos de sujetos, con discapacidad y control, una fotografía de una persona que tras una tarea distractora deberían identificar en dos ruedas de seis fotografías (una de objetivo ausente y otra de objetivo presente). Cada sujeto realizó cuatro ensayos, dos con fotografías de hombres y otras dos con fotografías de mujeres. Los resultados mostraron que las personas con discapacidad intelectual en comparación con los sujetos control cometían menos aciertos y más falsas alarmas y discriminaban peor las caras (d’), aunque con pocas diferencias en el criterio de respuesta (ß). La relación entre rendimiento y CI resultó significativa para algunos de los tipos de respuesta.
[ABSTRACT]
The aim of this study was to analyze the unfamiliar face recognition ability of people with mild and moderate intellectual disabilities and assess factors that might facilitate the task while minimizing errors. For this purpose, two groups had to recognize in two lineups with six photographs each (one present-target and one absent-target). Each subject performed four trials, two with pictures of men and two with women. Analysis of the results suggests that people with intellectual disabilities compared with control group made fewer hits and more false alarms and discriminate faces worst (d’), but with few differences in the response bias (ß). The relationship between unfamiliar face recognition performance and IQ was significant in some types of responses.
