Learning efficacy of explicit visuomotor sequences in children with attention-deficit/hyperactivity disorder and Asperger syndrome

Developmental disorders such as attention-deficit/hyperactivity disorder (ADHD) and Asperger syndrome (AS) are often associated with learning disabilities. This study investigated the explicit learning of visuomotor sequences in 17 ADHD children (mean age 12.1), 21 AS children (mean age 12.7), and 15 typically developing children (mean age: 12.3). The participants were required to explore a hidden sequence of button presses by trial and error and elaborate the learned sequence (2 × 10 task: Hikosaka et al. 1996). The results indicated that although ADHD and AS children had a tendency of repeating the same errors and took longer to complete a sequence, both showed a degree and pattern of improvement in accuracy and speed similar to that of typically developing children. These results suggest that the explicit learning of visuomotor sequence in ADHD and AS patients is largely unimpaired

Characteristics of Parents and Their Infants with Autistic Behaviors: Parent-Infant Interaction, Parental Depression, and Parenting Stress

Parents of infants with autistic behaviors frequently face difficulties in childrearing owing to their infants’ behavioral traits. This study aimed to clarify the characteristics of parent-infant interaction, parental depressive symptoms, and parenting stress in the context of infants’ autistic behaviors. We employed a cross-sectional, case-control observational design with a case group of 52 parents and a control group of 56 parents. We measured parent- infant interaction using the Japanese version of the Nursing Child Assessment Teaching Scale, and parental depressive symptoms and parenting stress with the Japanese version of the Center for Epidemiologic Studies Depression Scale and the Japanese Parenting Stress Index Short Form, respectively. There was no significant difference between the two groups regarding parent-infant interaction. Mothers in the case group had significantly higher depressive symptoms than those in the control group (p < .05). Both fathers (p < .05) and mothers (p < .01) in the case group scored significantly higher than the control group on parenting stress. Thus, parents of infants with autistic behaviors have greater mental health problems right from infancy. We suggest that nurses should provide families with appropriate support to promote adaptive parent-infant interaction and prevent the aggravation of parental mental health problems irrespective of Autism Spectrum Disorder diagnoses

A pilot study for robot appearance preferences among high-functioning individuals with autism spectrum disorder: Implications for therapeutic use

<div><p>Recent rapid technological advances have enabled robots to fulfill a variety of human-like functions, leading researchers to propose the use of such technology for the development and subsequent validation of interventions for individuals with autism spectrum disorder (ASD). Although a variety of robots have been proposed as possible therapeutic tools, the physical appearances of humanoid robots currently used in therapy with these patients are highly varied. Very little is known about how these varied designs are experienced by individuals with ASD. In this study, we systematically evaluated preferences regarding robot appearance in a group of 16 individuals with ASD (ages 10–17). Our data suggest that there may be important differences in preference for different types of robots that vary according to interaction type for individuals with ASD. Specifically, within our pilot sample, children with higher-levels of reported ASD symptomatology reported a preference for specific humanoid robots to those perceived as more mechanical or mascot-like. The findings of this pilot study suggest that preferences and reactions to robotic interactions may vary tremendously across individuals with ASD. Future work should evaluate how such differences may be systematically measured and potentially harnessed to facilitate meaningful interactive and intervention paradigms.</p></div
