Emotional prosody perception and production in dementia of the Alzheimer's type.

Purpose: In this study, the authors investigated emotional prosody in patients with moderate Dementia of the Alzheimer's type (DAT) With Late Onset. It was expected that both expression and reception of prosody would be impaired relative to age-matched controls.

Method: Twenty DAT and 20 control participants engaged in 2 expressive and 2 receptive tasks with randomly presented exemplars of sentences targeting the emotions of happiness, anger, sadness, and surprise.

Face to face: visual scanpath evidence for abnormal processing of facial expressions in social phobia.

Cognitive models of social phobia propose that cognitive biases and fears regarding negative evaluation by others result in preferential attention to interpersonal sources of threat. These fears may account for the hypervigilance and avoidance of eye contact commonly reported by clinicians. This study provides the first objective examination of threat-related processing in social phobia.

Social phobics do not see eye to eye: a visual scanpath study of emotional expression processing.

Clinical observation suggests that social phobia is characterised by eye avoidance in social interaction, reflecting an exaggerated social sensitivity. These reports are consistent with cognitive models of social phobia that emphasize the role of interpersonal processing biases. Yet, these observations have not been verified empirically, nor has the psychophysiological basis of eye avoidance been examined.
