Objective: To examine the manifestation of cognitive control deficit of children with different levels of hyperactivity, an "at risk" dimension for ADHD. Method: A group of children with high hyperactivity (N = 40) and another group of children with low levels of hyperactivity (N = 38) performed a modified stop-signal anticipation task,…

Remote association, the ability to form new relations between independent elements, was assessed using the Remote Associates Test (RAT). The Chinese RAT (CRAT) includes the Chinese radical RAT (CRRAT), Chinese word RAT (CWRAT), and Chinese compound RAT (CCRAT). Behavioral research indicates that an individual's performance on the CRAT reflects…

Children with autism spectrum disorder are often reported to have more sleep deficits and poorer sleep quality compared with children with typical development. However, most previous studies have serious methodological limitations, such as varying sample sizes in the comparison groups, wide age range of participants, and body mass index not…

In early childhood, young children frequently engage in object-oriented play. According to cultural-historical activity theory, object-oriented play provides children with opportunities to learn about the characteristics and cultural applications of objects and materials. These characteristics are referred to as rules or affordances of objects and…

Purpose: Language production, a dynamic process involving real-time language processing, is crucial for children's language and communication development. To explore the early development of children's real-time language production, this study investigated Chinese preschool children's pausing strategies in narratives and their associations with…

Repetitive behaviors are observed in autism spectrum disorder and obsessive-compulsive disorder. Clinically, obsessive-compulsive disorder obsessions are thought to drive repetitive or ritualistic behavior designed to neutralize subjective distress, while restricted and repetitive behaviors are theorized to be reward- or sensory-driven. Both…

Research Findings Research suggests children from low-income environments have vocabularies that differ from those of their higher-income peers. They may have basic knowledge of many words of which children from higher income environments have acquired sub- or supra-ordinate knowledge. This study sought to determine if children from low-income…

This study assessed the potential short-term effects of COVID-19 stay-at-home restrictions on ratings of ASD and comorbid symptoms severity and adaptive functioning of 69 youth, ages 8-16 years with ASD without intellectual disability. Parent/caregiver ratings were being collected in fall and spring over approximately two years when the…

To identify quantitative indicators of social communication dysfunctions, we explored the oculomotor performances in subjects with autism spectrum disorders. Discordant findings in the literature have been reported for oculomotor behavior in subjects with autism spectrum disorders. This study aimed to explore reflexive and voluntary saccadic…

Purpose: Disfluencies associated with stuttering generally occur in the initial position of words. This study reviews data from a school-age child with an atypical stuttering profile consisting predominantly of word-final disfluencies (WFDs). Our primary goals were to identify patterns in overt features of WFDs and to extend our understanding of…

This study assessed the potential short-term effects of COVID-19 stay-at-home restrictions on ratings of ASD and comorbid symptoms severity and adaptive functioning of 69 youth, ages 8-16 years with ASD without intellectual disability. Parent/caregiver ratings were being collected in fall and spring over approximately two years when the…

There are few studies of behavior problems in preterm children prior to 2 years old and the changes that occur over time. The aims of this study were to examine the patterns and prediction of behavior problems and the effects of gender and socioeconomic status (SES) on behavior problems in preterm children at the toddler and preschool periods.…

Mimicry involves unconsciously copying the actions of others. Increasing evidence suggests that autistic people can copy the goal of an observed action but show differences in their mimicry. We investigated mimicry in autism spectrum disorder (ASD) within a two-dimensional virtual reality environment. Participants played an imitation game with a…

Background: Changes in reward processing are thought to be involved in the etiology of attention-deficit/hyperactivity disorder (ADHD), as well as other developmental disorders. In addition, different forms of therapy for ADHD rely on reinforcement principles. As such, improved understanding of reward processing in ADHD could eventually lead to…

The present study investigated how Chinese children develop theory of mind (ToM) in a language environment with limited mental state talk that is rich in behavior discourse. In Study 1, 60 mothers shared a wordless storybook with their 3-4-year-olds. The children completed two false-belief tasks and the Peabody Picture Vocabulary Test-Revised at…
