There is evidence that visuo-spatial capacity can become overloaded when
processing a secondary visual task (Dual Task, DT), as occurs in daily
life. Hence, we investigated the influence of the visuo-spatial
interference in the identification of emotional facial expressions
(EFEs) in early stages of Parkinson's disease (PD). We compared the
identification of 24 emotional faces that illustrate six basic emotions
in, unmedicated recently diagnosed PD patients (16) and healthy adults
(20), under two different conditions: a) simple EFE identification, and
b) identification with a concurrent visuo-spatial task (Corsi Blocks).
EFE identification by PD patients was significantly worse than that of
healthy adults when combined with another visual stimulus.
