Abstract

Introduction. Previous research has shown that correct identification of
emotional facial expressions (EFE) depends on the cognitive resources
that are available. In this study, we examine whether the capacity to
identify EFE in a dual task paradigm is affected in Parkinson's disease
(PD). Aim. To investigate the interference generated by introducing a
secondary task in EFE processing during the encoding and recovery of the
facial expression in non-medicated PD patients. Subjects and methods. A
total of 14 patients with de novo PD and 28 healthy adults identified
24 EFE under two conditions: simultaneous encoding along with a
secondary task and introduction of the secondary task between the time
that spans the encoding of the primary task and the response time
latency. Results. Results showed that identification of EFE by patients
with PD was significantly worse than by healthy adults in the
simultaneous encoding condition. In contrast, no differences were found
when the interference of the secondary task took place in the phase
involving recovery of information of the primary task. Conclusions.
Patients with PD only display specific deficits in processing EFE when
the task consumes high levels of the resources required for divided
attention, as occurs in everyday situations.
