Abstract： Social interaction impairment is one of the core symptoms of children with Autistic Spectrum Disorders (ASD) which requires early intervention for successful social skills. The conventional approaches of psychological rehabilitation have many limitations such as time consuming, high cost, and shortage of professional rehabilitation therapists. With the development of artificial intelligence, social robots with their unique strengths are widely used in improving social interactions of children with ASD. This paper discusses the potential of social robots in the treatment of autism spectrum disorder and the current applications of social robots for the therapeutic treatment of joint attention, self-initiations, motor imitation, and other social function in ASD patients. It also analyzes the strengths and weaknesses of social robots during the intervention in terms of experimental environments and methods among other factors. It is proposed that future research can be conducted to develop new social scenarios based on the characteristics of human-robot interaction; combine multimodality and brain science and technology to reveal the psychological process of human-robot interaction; construct closed-loop systems for social robots by leveraging the advancing artificial intelligence technology.

Abstract： Attentional blink (AB) is a phenomenon in which identifying the second of two targets (T2) is impaired when it appears 200~500 ms after the first target (T1). This phenomenon reflects the limitation of conscious processing in the temporal dimension. However, emotional T2 can attenuate AB compared to neutral T2. This provides an observation window and research means for understanding the preferential processing of emotional stimuli. The phenomenon of emotional T2 attenuating AB is influenced by factors such as the difficulty of T1, the task demand of T2 and emotional expectation. The brain regions primarily involved in emotional T2 attenuating AB include the amygdala, anterior cingulate cortex, and orbitofrontal cortex. In the temporal dimension, compared to neutral T2, emotional T2 exhibits enhanced effects in both the early and late stages of cognitive processing. The “Attentional Enhancement and Consolidation Competition Hypothesis” was proposed to explain the underlying mechanism of emotional T2 attenuating AB. The early attentional capture of emotional information mediated by the amygdala is key to reducing AB for emotion, while task demand and other top-down factors modulate the late consolidation process.
