15 sighted and 15 congenitally blind adults were to classify raised-line pictures of emotional faces through haptics. Whereas accuracy did not vary significantly between the two groups, the blind adults were faster at the task. These results suggest that raised-line pictures of emotional faces are intelligible to blind adults.
