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.

RENTERIA-VAZQUEZ, Auteur ; W. S. BROWN, Auteur ; C. KANG, Auteur ; M. GRAVES, Auteur ; F. CASTELLI, Auteur ; L. K.

This research compared the ability of 14 adults with AgCC, 13 high-functioning adults with ASD and 14 neurotypical controls to accurately attribute social meaning to the interactions of animated triangles. Descriptions of the animations were analyzed in three ways: subjective ratings, Linguistic Inquiry and Word Count, and topic modeling (Latent Dirichlet Allocation). Although subjective ratings indicated that all groups made similar inferences from the animations, the index of perplexity (atypicality of topic) generated from topic modeling revealed that inferences from individuals with AgCC or ASD displayed significantly less social imagination than those of controls.
