We investigated low-level auditory spectral and temporal processing in adolescents with autism spectrum disorder (ASD) and early language delay compared to matched typically developing controls. Auditory measures were designed to target right versus left auditory cortex processing (i.e. frequency discrimination and slow amplitude modulation (AM) detection versus gap-in-noise detection and faster AM detection), and to pinpoint the task and stimulus characteristics underlying putative superior spectral processing in ASD. We observed impaired frequency discrimination in the ASD group and suggestive evidence of poorer temporal resolution as indexed by gap-in-noise detection thresholds. These findings question the evidence of enhanced spectral sensitivity in ASD and do not support the hypothesis of superior right and inferior left hemispheric auditory processing in ASD.

This study evaluated the effects of a behavioral summer treatment program for children with high-functioning autism spectrum disorder (HFASD). Twenty boys (M = 9.2 years) diagnosed with HFASD participated in the 6-week program across 6 years. Detailed daily behavioral data were collected on a variety of positive and negative social behaviors. Repeated measures ANOVAs of weekly behavior frequencies indicated substantial improvements in a number of behaviors over the 6 weeks of the program, including following activity rules, contributing to a group discussion, paying attention, and less complaining/whining. Overall, results highlight the potential efficacy of treating chronic functional impairments of HFASD and associated problem behaviors in the context of an intensive behavioral summer treatment program.

Increasingly researchers are attempting to develop robotic technologies for children with autism spectrum disorder (ASD). This pilot study investigated the development and application of a novel robotic system capable of dynamic, adaptive, and autonomous interaction during imitation tasks with embedded real-time performance evaluation and feedback. The system was designed to incorporate both a humanoid robot and a human examiner. We compared child performance within system across these conditions in a sample of preschool children with ASD (n = 8) and a control sample of typically developing children (n = 8). The system was well-tolerated in the sample, children with ASD exhibited greater attention to the robotic system than the human administrator, and for children with ASD imitation performance appeared superior during the robotic interaction.
