SSPS Participant Information


The study overview is a "play-by-play" picture story of the study activities during the three study visits. This is intended as a detailed visualization aid for your child. For additional information about the MRI and a preparation MRI video, see the MRI Information page.


What is being studied?


Dr. Natalia Kleinhans, an associate professor of radiology, is leading a team of researchers from the University of Washington to better understand the biochemical, brain, and behavioral causes of social challenges and sensory sensitivity in children with autism. The information gained in this study will lead to advancements in our understanding of individuals with autism and sensory processing disorder.


Who can participate?


We are seeking 8 to 12 year olds with high functioning autism, 8-12 year olds with sensory processing challenges, and 8-12 year olds who are typically developing. Your child would participate in two to three sessions, each between 1 hr. and 4 hrs. in length. The study uses questionnaires, behavioral tasks, a brain scan and a nasal cell collection.


What does the study involve?


Participation includes 3 visits to the University of Washington Autism Center/Center for Human Development and Disability, as well as two phone interviews. Activities include IQ testing, autism diagnostic evaluations, questionnaires, smell testing and a nasal cell collection with a physician.


How will I benefit from participating?


Participants will earn up to $125, get to see a picture of their brain, and receive a comprehensive report written by the University of Washington Autism Center clinician conducting the IQ testing and autism diagnostic evaluations that are a part of this study. This report will include IQ test results, autism diagnostic results, recommendations for future progress and suggestions regarding resources supporting progress.


Where and when does the study take place?


Our study takes place at the Center on Human Development and Disability (CHDD) at the University of Washington Kleinhans Lab. We will schedule your visits at a convenient time for you.

Nephi Stella, Ph.D.

UW Pharmacology Profile

Nephi Stella and his colleagues study the biological mechanisms that control the amplitude of neuroinflammatory responses in the central nervous system. Their goal is to generate specific drugs that may temper central nervous system inflammation, ssuch as the inflammation associated with Alzheimer's disease and multiple sclerosis, and the associated neural damages.
