Abstract:
Face perception and emotion recognition were investigated in
a group of people with Huntington's disease. We used a battery of
conventional tasks studying the different aspects of face
information as well as recognition of voice expressions. Mild
impairments are observed on the face tasks. Impairments on the
recognition of emotion in the face and the selectively voice are
more servere but are not for one or another emotion category. A
second set of tasks examined perception of emotion in bimodal
situations where the face and the voice are presented concurrently.
The goal of these tasks was to study whether these two sources are
combined as they are in normals. In contrast to the latter,
Huntington patients appear to have a problem with bimodal
integration.
