Abstract Conversational impairments are well known among people with autism spectrum disorder ASDbut their measurement requires time-consuming manual annotation of language samples. Natural language processing NLP has visit web page promise in identifying semantic difficulties when compared to clinician-annotated reference transcripts. We hypothesized that: a semantic coherence, as measured by this method, would discriminate between children with and without ASD and b more variability would be found in the group with ASD.

Transcripts were converted to vectors via a word2vec model trained on the Google News Corpus.

Pairwise similarity across all subjects and a sample grand mean were calculated. Means of pseudo-values were compared between the two groups. Analyses were co-varied for nonverbal IQ, mean length of utterance, and number of distinct word roots NDR. TD subjects had higher pseudo-value scores suggesting that similarity scores of TD subjects were more similar to the overall group mean. Variance of pseudo-values was greater in the ASD group.

What is autism spectrum disorder in children?

The findings suggest that our pseudo-value-based method can be effectively used to identify specific semantic difficulties that characterize children with ASD without requiring a reference transcript. Keywords: autism, language disorder, semantics, natural language proceeding, child, statistical methods Introduction Autism spectrum disorder ASD is a neurodevelopmental disorder characterized by deficits in social communication and social interaction, and patterns of restricted or repetitive behavior.

While atypical language use, repetitive speech, and perseverative interests are all features of see more disorder as characterized by the DSM-5 American Psychiatric Association,quantifying what is atypical about the language of subjects with ASD is challenging.

The use of unusual words has been found to be more prevalent in speakers with ASD Volden and Lord, ; however, coding what is unusual about these words requires linguistic and clinical expertise. Additionally, identifying repetitive, stereotyped, or non-contingent speech in dialogues can be complicated by the presence of a perseverative interest. Current methods in assessing pragmatic speech are time-intensive and potentially subjective Adams, ; Klusek et al.

Computational methods of measuring differences in language production in subjects with ASD, such as the one proposed in this work, have the potential to provide objective, quantitative measures, which could be in turn used in clinical applications, such as evaluating response to intervention. While there are a number of conversational impairments that we could consider, in this study, we explore what children talk about when presented with similar conversational contexts, and if that semantic content differs between children with and without ASD. We expect to capture lexico-semantic differences between diagnostic groups — e.

We hypothesize that when subjects are asked questions about a series of topics, that there should be some degree of similarity due to a constrained lexicon of topic-appropriate responses. In line with generally greater variability of clinical variables language, here, and behavioral that describe the autism phenotype, we also expected that there should be a fair amount of lexical variability in those responses and that this should increase in subjects with ASD.

Prior research Losh and Gordon, ; Goodkind et al. However, as discussed below, those experiments have traditionally relied on a reference text or transcript representing an idealized typical response.

This is a novel approach based on an analysis of pseudo-values PVs similar to that used in risk analysis Klein and Andersen, ; Ahn and Mendolia, This provides us with a statistically tractable measure that can detect the sort of systematic language differences found by Losh and Gordon and Goodkind et al. Natural language processing is the subfield of computer science focused on analysis of click and language.]

Tuberous sclerosis Chromosome problems Your child may need genetic testing to help find out if another problem has contributed. The testing is done by a medical geneticist. This is a healthcare provider with special training in genetics and inherited problems. They can let you know the chances of having another child with the gene problem. For example, PKU carries a 1 in 4 chance of happening in another pregnancy. For tuberous sclerosis, the chances are 1 in 2. Even when no gene problem is found, you are at a slightly higher chance of having another child with ASD.
