This study aims to evaluate the remote delivery of self-regulation assessments in young children with autism and their parents. Parents will complete online surveys. Parents and children will complete two virtual visits. At the second visit, participants will wear a heart rate monitor while completing study tasks. This study will inform research on behavioral therapies for children with autism.

Currently, there are no FDA-approved medications for the treatment of irritability associated with Autism Spectrum Disorder (ASD). This study is designed to look at the usefulness and safety of lumateperone (CAPLYTA) for the treatment of irritability associated with ASD among pediatric participants between the ages of 5 to 17 years. The study will last approximately 26 weeks and the participants will receive the study drug, lumateperone.

It is a 6-week study, and the study drug will be compared to a placebo. Following this study, there will be an opportunity to participate in an open-label extension study where all participants will be on the active study medicine.

The purpose of this study is to explore whether a non-invasive form of ear stimulation called transcutaneous auricular vagus nerve stimulation (taVNS) can manage symptoms in patients with autism spectrum disorder (ASD). Additionally, this study also uses magnetic resonance imaging (MRI) to capture images of participants' brains and apply an image processing method called INSCAPE to track brain state changes during taVNS treatment in ASD. We will recruit up to 16 participants with ASD.

The purpose of this research is to assess a group-based telehealth parenting program for child ages 2-6 years old with a neurodevelopmental diagnosis and behavior problems. Families will complete an online intake assessment, 6 group-based telehealth PCIT sessions, and an online post intervention assessment. Families will be compensated for their time.
