Hearing the feeling: Auditory emotion perception in Williams syndrome.

Background: Studies investigating recognition of facial expressions of emotions in Williams syndrome (WS) have reported difficulties in recognising negative expressions of emotion and a reliance on atypically developing underlying processes during task performance.

Aim: The aim of the study was to extend these findings to the recognition of emotions in auditory domains.

Method And Procedures: Children and adolescents with WS, together with chronological (CA) and verbal mental age matched (VMA) typically developing (TD) comparison groups, were asked to judge expressions of happiness, sadness, anger, and fear in vocal and musical conditions.

Delayed auditory feedback simulates features of nonfluent primary progressive aphasia.

The pathophysiology of nonfluent primary progressive aphasia (nfvPPA) remains poorly understood. Here, we compared quantitatively speech parameters in patients with nfvPPA versus healthy older individuals under altered auditory feedback, which has been shown to modulate normal speech output. Patients (n=15) and healthy volunteers (n=17) were recorded while reading aloud under delayed auditory feedback [DAF] with latency 0, 50 or 200 ms and under DAF at 200 ms plus 0.
