Among the numerous applications are physical rehabilitation and imitation games. In this work, we suggest performing human gesture recognition within the context of a serious imitation game, which would aim at improving social interactions with teenagers with autism spectrum disorders. We use an artificial intelligence algorithm to detect the skeleton of the participant, then model the human pose space and describe an imitation learning method using a Gaussian Mixture Model in the Riemannian manifold.展开更多

Compared with the ADSL group, the early-onset CDD group had a tendency to have a higher rate of a psychosocial event before speech loss (SL) (early-onset CDD, 75.0% vs ADSL, 37.0%, p = 0.057;effect size (phi) = 0.211, p < 0.05);a significantly higher rate of fearfulness during SL (62.5% vs 4.3%, p = 0.000;phi = 0.551, p < 0.05);and a tendency to have a higher rate of epilepsy (25.0% vs 3.3%, p = 0.050;phi = 0.271, p < 0.05), a tendency to have a lower rate of the Childhood Autism Rating Scale-Tokyo Version (CARS-TV) total score ≥ 30 (75.0% vs 95.7%, p = 0.072;phi = 0.236, p < 0.05), and a significantly lower rate of CARS-TV item 2 (imitation) score ≥ 2 (50.0% vs 82.6%, p = 0.049;phi = 0.221, p < 0.05) on the first visit. The two groups did not exhibit any significant difference in the other 19 variables. The findings of no significant difference in the great majority and a significant difference in the small minority of the 24 variables between the two groups support integrating CDD into regressive autism spectrum disorder and studying CDD as its prototypical form.展开更多

The developmental trajectory of schizophrenia may be characterized by difficulties in “theory of mind” tasks, poor insight or imagination, low empathy level, weak executive function, failure in social judgments, delayed language development, movement mannerisms, motoric rituals, strong preoccupation with unusual objects, bizarre habits, and high intelligence. Most of these characteristics are associated with the standard criteria for ASD and all of them are core domains or endophenotypes of ASD. The diagnosed ASD cases, which were found in individuals with schizophrenia, have a significant tendency to be highfunctioning and to have atypical age of ASD manifestation. Episodic features including reality distortion, which can be seen in individual with ASD, may be associated with hyperarousal conditions with cognitive hypersensitivity, misattribution of negative experiences, and the perceptual thinking style. Together with the emerging new genetic concepts concerning human behavioral complex traits, the results and constructions of these recent studies may further warrant that reconsideration of the relationship between ASD and psychotic conditions is necessary. In addition, the possibility that psychotic conditions are the secondary derivative states in individuals with ASD or in individuals with subclinical ASD components should be constructively examined.展开更多

Block design test was used to locate and follow constructional apraxia, computerized information processing speed test to locate and follow cognitive processing and grooved pegboard test was used to locate and follow fine motor skills. The variance between pre- and post-treatment results was highly significant in the study group in all variables. By comparison of the two groups in constructional apraxia variables test at post-treatment, there was a highly representative elevation in favour to study groups (p < 0.05). By comparison of the two groups in cognitive processing variable at post-treatment, there was a highly representative elevation in favour to study group (p < 0.05). By comparison of the two groups in fine motor skills variable at post-treatment, there was a highly representative elevation in favor to study group (p < 0.05). According to the outcomes of this study, it can be terminated that the sensory integration therapy approach plus static and intermittent inversion therapy techniques can be recommended in improvement constructional apraxia and cognitive processing abilities in autism spectrum disorder (ASD) children.展开更多
