To investigate whether these patients had other deficits in emotional processing, a highly symptomatic group of five patients was given a standardized test for the perception of emotional cues conveyed through facial expression, body posture, or vocal intonation (PONS). Performance equaled or exceeded those of normal subjects, distinguishing patients with GTS from those with idiopathic psychoses or cortical lesions of the posterior right hemisphere. We suggest that GTS is a selective disorder of involuntary emotional expression in which emotional perception is normal. © Lippincott-Raven Publishers.
