Brain clock ticks differently in autism -- ScienceDaily

Sensory areas of the brain that receive input from the eyes, skin and muscles usually have shorter processing periods compared with higher-order areas that integrate information and control memory and decision-making. The new study, published in the journal eLife on February 5, shows that this hierarchy of intrinsic neural timescales is disrupted in autism. Atypical information processing in the brain is thought to underlie the repetitive behaviors and socio-communicational difficulties seen across the spectrum of autistic neurodevelopmental disorders (ASD), but this is one of the first indications that small-scale temporal dynamics could have an outsized effect.

Social tool box improves autistic social responsiveness

In the study, 22 people aged 18 to 24 and their caregivers were randomly assigned either to receive the PEERS treatment or to be part of a control group in which treatment was delayed. Those in the PEERS group received training on social etiquette related to conversational skills, humor, electronic communication, identifying sources of friends, entering and exiting conversations, organizing successful get-togethers, and handling peer conflict and peer rejection. The young adults in the PEERS group also received four sessions on dating etiquette. The PEERS approach teaches skills using concrete rules and steps of social behavior via lessons, role-play demonstrations, behavioral rehearsal exercises and assignments to practice the skills in natural social settings. Caregivers (including parents and other family members, job and life coaches, and peer mentors) are also provided tips to help participants use their skills in the real world. Among members of the PEERS group, social skills, frequency of social engagement and social skills knowledge improved significantly, and autism symptoms related to social responsiveness diminished. In addition, 16 weeks after the treatment ended, most of the gains were still evident, and the researchers observed new improvements in social communication, assertion, responsibility and empathy -- a result the scientists attributed to the involvement of caregivers as social coaches.
