This paper addresses the problem of emotion recognition in faces through an intelligent neuro-fuzzy system, which is capable of analysing facial features extracted following the MPEG-4 standard, associating these features to symbolic fuzzy predicates, and reasoning on the latter, so as to classify facial images according to the underlying emotional states. Results are presented which illustrate...

Facial feature point tracking is used as a primary input in several systems that perform affect recognition using facial expressions. To determine the efficacy of automatically extracted facial feature points in encoding emotional content, we conducted an experiment that compared human raters judgements of emotional expressions between actual video clips and three automatically generated repres...

According to embodied simulation theory, understanding other people's emotions is fostered by facial mimicry. However, studies assessing the effect of facial mimicry on the recognition of emotion are still controversial. In Parkinson's disease (PD), one of the most distinctive clinical features is facial amimia, a reduction in facial expressiveness, but patients also show emotional disturbances...

BACKGROUND Recent behavioral and psychophysiological studies have provided converging evidence for emotional dysfunction in conduct disorder (CD). Most of these studies focused on male subjects and little is known about emotional processing in female subjects with CD. Our primary aim was to characterize explicit and implicit aspects of emotion function to determine whether deficits in these pro...

Navigating our complex social world requires effective processing of subtle emotional signals, such as those conveyed by facial expressions. Failure to do so may underlie some of the disabling social-emotional deficits common in a range of neuropsychiatric and neurological conditions. Prefrontal cortex (PFC) has long been implicated in these processes, but the particular contributions of subreg...

BACKGROUND Frontotemporal lobar degeneration (FTLD) is associated with a profound decline in social and emotional behavior; however, current understanding regarding the specific aspects of emotional functioning that are preserved and disrupted is limited. OBJECTIVE To assess preservation of function and deficits in two aspects of emotional processing (emotional reactivity and emotion recognit...

Disturbed processing of emotional faces and voices is typically observed in schizophrenia. This deficit leads to impaired social cognition and interactions. In this study, we investigated whether impaired processing of emotions also affects musical stimuli, which are widely present in daily life and known for their emotional impact. Thirty schizophrenic patients and 30 matched healthy controls ...

Facial expressions play a key role in affective and social behavior. However, the temporal dynamics of the brain responses to emotional faces remain still unclear, in particular an open question is at what stage of face processing expressions might influence encoding and recognition memory. To try and answer this question we recorded the event-related potentials (ERPs) elicited in an old/new re...

Patients with Huntington's disease (HD) exhibit motor impairments as well as cognitive and emotional deficits. So far impairments in the ability to recognize emotional stimuli have mostly been investigated by using facial expressions and emotional voices. Other important emotional signals are provided by the whole body. To investigate the impact of motor deficits on body recognition and the rel...
