Enhanced neural synchronization during social communications between dyads with high autistic traits.

Autism is characterized by atypical social communication styles. To investigate whether individuals with high autistic traits could still have effective social communication among each other, we compared the behavioral patterns and communication quality within 64 dyads of college students paired with both high, both low, and mixed high-low (HL) autistic traits, with their gender matched. Results revealed that the high-high (HH) autistic dyads exhibited atypical behavioral patterns during conversations, including reduced mutual gaze, communicational turns, and emotional sharing compared with the low-low and/or HL autistic dyads. However, the HH autistic dyads displayed enhanced interpersonal neural synchronization during social communications measured by functional near-infrared spectroscopy, suggesting an effective communication style. Besides, they also provided more positive subjective evaluations of the conversations. These findings highlight the potential for alternative pathways to effectively communicate with the autistic community, contribute to a deeper understanding of how high autistic traits influence social communication dynamics among autistic individuals, and provide important insights for the clinical practices for supporting autistic people.

Autistic and Non-autistic Children's Pain Perception is Modulated by Their First-Hand Pain Sensitivity and Theory of Mind.

The current study examined whether autistic children's perception of others' pain could be modulated by their first-hand pain sensitivity and theory of mind (ToM). We measured the first-hand pain sensitivity, the rating of others' pain intensity, and the performance in the ToM tasks in 43 5- to 8-year-old autistic and 30 neurotypical children. Our results revealed hyposensitivity to first-hand pain, underestimation of others' pain intensity, as well as difficulties in the False Belief subtasks of ToM in autistic children. Furthermore, we detected an interaction between children's first-hand pain sensitivity and ToM in predicting their perception of others' pain. To be specific, for autistic and NT children with normal or hyper-sensitivity to first-hand pain, better performance on ToM predicted higher ratings for others' pain intensity; while for autistic and NT children with hyposensitivity to first-hand pain, ToM did not predict ratings for others' pain intensity. Our study contributes to the understanding of pain perception in young children and provides implications for clinical practices to improve social understanding in autistic children.

The Relationship Between Theory of Mind and Listening Comprehension Among Chinese Preschoolers with and without Autism Spectrum Disorder.

The study aimed to examine the performance on linguistic and cognitive tasks among Chinese preschool children with and without autism spectrum disorder (ASD) and explore the direct and indirect relationships between theory of mind (ToM) and literal and inferential listening comprehension. Forty-nine (N = 49) children with ASD and fifty-two (N = 52) age- and gender-matched typically developing (TD) children participated in the study. All participants were administered tasks evaluating their listening comprehension of literal and inferential statements, ToM, as well as verbal and nonverbal IQ. Results showed that the ASD group performed statistically worse on listening comprehension, ToM abilities, verbal IQ, and nonverbal IQ than their TD peers. Further, we found statistically significant correlations between general ToM performance and overall listening comprehension among Chinese preschool children with and without ASD. More specifically, ToM abilities of children with ASD had an indirect effect on their literal listening comprehension via the mediation of verbal IQ, whereas ToM performance among TD children predicted their literal listening comprehension via the mediation of nonverbal IQ. The major findings were discussed in detail based on the situation model. The research facilitated insights into listening comprehension among Chinese preschool children with and without ASD, providing their caregivers and teachers with viable strategies to improve their listening comprehension.

Empathy in autistic children: Emotional overarousal in response to others' physical pain.

Different empathic responses are often reported in autism but remain controversial. To investigate which component of empathy is most affected by autism, we examined the affective, cognitive, and motivational components of empathy in 25 5- to 8-year-old autistic and 27 neurotypical children. Participants were presented with visual stimuli depicting people's limbs in painful or nonpainful situations while their eye movements, pupillary responses, and verbal ratings of pain intensity and empathic concern were recorded. The results indicate an emotional overarousal and reduced empathic concern to others' pain in autism. Compared with neurotypical children, autistic children displayed larger pupil dilation accompanied by attentional avoidance to others' pain. Moreover, even though autistic children rated others in painful situations as painful, they felt less sorry than neurotypical children. Interestingly, autistic children felt more sorry in nonpainful situations compared with neurotypical children. These findings demonstrated an emotional overarousal in response to others' pain in autistic children, and provide important implications for clinical practice aiming to promote socio-emotional understanding in autistic children.
