Further exploring diversified social cognition (e.g., biological motion perception) will provide a new understanding of impaired social function in ADHD. Other social cognition processes in ADHD are unclear. It is difficult for children with ADHD to recognize others’ emotions and purposes. Among them, impaired theory of mind (ToM) and emotion recognition are most frequently reported 5– 7. Some studies described worse performance in tasks of social cognition. However, experimental studies of social cognition in ADHD are still scarce. Besides the well-established core symptoms of ADHD (including a deficit of sustained attention, hyperactivity, and impulsivity), some ASD characteristics, such as dysfunctions in social communication and social interaction, have also been frequently reported in ADHD children 2– 4. The prevalence of ADHD in children and adolescents is between 2% and 7%, with an average of around 5% 1. The results are useful in terms of understanding ADHD and the ontogenesis of different components of the processing of biological motion.Īttention deficit/hyperactivity disorder (ADHD) is a common developmental disorder. The group differences concerning accuracy in global and local motion processing abilities are solid, but the analyses suggesting dissociable relationships between global and local processing and social skills, age, and IQ need further interrogation.
This manuscript represents a cleanly designed experiment for assessing biological motion processing in children (mean age = 9) with and without ADHD. Moreover, this study provides new evidence for local BM perception as a hallmark of social cognition and advances the comprehensive understanding of the distinct roles of local and global processing in BM perception and social cognitive disorders.
These findings elucidate the atypical biological motion perception in ADHD and the potential factors related to BM perception. This relationship was mainly mediated by Reasoning Intelligence. Critically, general BM perception (i.e., both local and global BM cues) was affected by sustained attention ability in ADHD. Local BM processing ability was largely related to social interaction skills, whereas global BM processing ability would significantly improve with age. Results revealed that children with ADHD exhibited atypical BM perception with a clear dissociation between local and global BM information processing. Then, we further investigated the relationship between BM perception and social interaction skills measured by the Social Responsiveness Scale (SRS) and examined the contributions of potential factors (e.g., gender, age, attention and intelligence) to BM perception. Here, we compared the differences in abilities to process local kinematic and global configurational cues, two fundamental abilities of BM perception, between typically developing (TD) and ADHD children.
Children with attention deficit hyperactivity disorder (ADHD) often exhibit similar deficits in social interaction, but few studies have investigated BM perception in ADHD. Plentiful studies have found impaired BM perception in autism spectrum disorder characterized by deficits in social interaction. The ability to perceive biological motion (BM) is crucial for human survival and social interaction.
