Abstract Emotion recognition (ER) was examined in 64 patients with idiopathic Parkinson's disease (PD; 56 bilateral and 8 right‐sided) and 64 matched healthy volunteers. Participants were administered an ER battery, consisting of the following subscores: overall ER (OER), overall facial ER, facial emotion identification (FEI) and discrimination, overall prosodic ER, and prosodic emotion identification (PEI) and discrimination. Measures of visuospatial functions, auditory attention, and depression were also administered. After controlling for visuospatial functions, auditory attention and depression, results indicated that patients with bilateral PD had poorer performance on all ER subscores, regardless of the modality and type of experimental task involved, relative to healthy volunteers. However, patients with right‐sided PD had difficulty on FEI and PEI only. Whereas none of the clinical variables examined in this study predicted any of the ER subscores, visual organization and auditory attention positively predicted OER in patients with PD. In addition, visual organization also positively predicted FEI in these patients. Implications are discussed in terms of the neural substrates underlying ER. © 2003 Movement Disorser Society
