Facial emotion recognition in agenesis of the corpus callosum / M. W. BRIDGMAN in Journal of Neurodevelopmental Disorders, 6-1 (December 2014)
[article]
Titre : Facial emotion recognition in agenesis of the corpus callosum Type de document : Texte imprimé et/ou numérique Auteurs : M. W. BRIDGMAN, Auteur ; W. S. BROWN, Auteur ; M. L. SPEZIO, Auteur ; M. K. LEONARD, Auteur ; Ralph ADOLPHS, Auteur ; L. K. PAUL, Auteur Article en page(s) : p.32 Langues : Anglais (eng) Mots-clés : Corpus callosum Corpus callosum agenesis Facial emotion Index. décimale : PER Périodiques Résumé : BACKGROUND: Impaired social functioning is a common symptom of individuals with developmental disruptions in callosal connectivity. Among these developmental conditions, agenesis of the corpus callosum provides the most extreme and clearly identifiable example of callosal disconnection. To date, deficits in nonliteral language comprehension, humor, theory of mind, and social reasoning have been documented in agenesis of the corpus callosum. Here, we examined a basic social ability as yet not investigated in this population: recognition of facial emotion and its association with social gaze. METHODS: Nine individuals with callosal agenesis and nine matched controls completed four tasks involving emotional faces: emotion recognition from upright and inverted faces, gender recognition, and passive viewing. Eye-tracking data were collected concurrently on all four tasks and analyzed according to designated facial regions of interest. RESULTS: Individuals with callosal agenesis exhibited impairments in recognizing emotions from upright faces, in particular lower accuracy for fear and anger, and these impairments were directly associated with diminished attention to the eye region. The callosal agenesis group exhibited greater consistency in emotion recognition across conditions (upright vs. inverted), with poorest performance for fear identification in both conditions. The callosal agenesis group also had atypical facial scanning (lower fractional dwell time in the eye region) during gender naming and passive viewing of faces, but they did not differ from controls on gender naming performance. The pattern of results did not differ when taking into account full-scale intelligence quotient or presence of autism spectrum symptoms. CONCLUSIONS: Agenesis of the corpus callosum results in a pattern of atypical facial scanning characterized by diminished attention to the eyes. This pattern suggests that reduced callosal connectivity may contribute to the development and maintenance of emotion processing deficits involving reduced attention to others' eyes.

CHAN, Auteur Article en page(s) : p.1567-1577 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Facial emotion Social Connectivity Theta Coherence Index. décimale : PER Périodiques Résumé : A growing body of evidence suggests that autism spectrum disorders (ASD) is associated with altered functional connectivity of the brain and with impairment in recognizing others’ emotions. To better understand the relationships among these neural and behavioral abnormalities, we examined cortical connectivity which was indicated by theta coherence during tasks of facial emotion recognition in 18 children with ASD and 18 typically developing (TD) children who were between 6 and 18 years of age. We found that the children with ASD had general impairment in recognizing facial emotions, after controlling for response bias. Additionally, we found that the TD children demonstrated significant modulation of right frontal theta coherence in response to emotional faces compared to neutral faces, whereas children with ASD did not exhibit any modulation of theta coherence. The extent of modulation of theta coherence to emotions was further found to be related to the severity of social impairments in ASD. Our findings of a general impairment in facial emotion recognition and the involvement of disordered cortical connectivity in social deficits in children with ASD have shed light for future exploration of interventions regarding emotional processing and social functioning in ASD.

Global integration requires extraction of regularity across various timescales, yet little is known about how individuals with ASD process regularity at local (short timescale) versus global (long timescale) levels. To this end, we used event-related potentials to investigate whether individuals with ASD would show different neural responses to local (within trial) versus global (across trials) emotion regularities extracted from sequential facial expressions; and if so, whether this visual abnormality would generalize to the music (auditory) domain. Twenty individuals with ASD and 21 age- and IQ-matched individuals with typical development participated in this study. At an early processing stage, ASD participants exhibited preserved neural responses to violations of local emotion regularity for both faces and music. At a later stage, however, there was an absence of neural responses in ASD to violations of global emotion regularity for both faces and music. These findings suggest that the autistic brain responses to emotion regularity are modulated by the timescale of sequential stimuli, and provide insight into the neural mechanisms underlying emotional processing in ASD.

Given research suggesting individuals with autism spectrum disorders (ASD) have difficulty processing emotions, we used the circumplex model to compare how individuals with ASD and typically-developing (TD) individuals respond to facial emotions. Participants (51 ASD, 80 TD) rated facial expressions along arousal and valence dimensions; we fitted closed, smooth, 2-dimensional curves to their ratings to examine overall circumplex contours. We modeled individual and group influences on parameters describing curve contours to identify differences in dimensional effects across groups. Significant main effects of diagnosis indicated the ASD-group’s ratings were constricted for the entire circumplex, suggesting range constriction across all emotions. Findings did not change when covarying for overall intelligence.
