Social Inferences in Agenesis of the Corpus Callosum and Autism: Semantic Analysis and Topic Modeling

J Autism Dev Disord. 2021 Mar 25. doi: 10.1007/s10803-021-04957-2. Online ahead of print.ABSTRACTImpoverished capacity for social inference is one of several symptoms that are common to both agenesis of the corpus callosum (AgCC) and Autism Spectrum Disorder (ASD). 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.PMID:33768420 | DOI:10.1007/s10803-021-04957-2
