He is supervising psychologist at the Minnesota Early Autism Project and a professor in the Department of Pediatrics at the University of Minnesota School of Medicine. He has received The Arc USA Distinguished Research Award, the Academy on Mental Retardation Life Time Research Award, the Don Hake Award of the American Psychological Association, and the Edgar A. Doll Award for his contributions to facilitating the transfer of research on intellectual and developmental disabilities into practice. Dr. Thompson has a grandson with an autism spectrum disorder. **Anastasia Dimitropoulos, Ph.D.** is a neuroimaging specialist and an assistant professor in the Department of Psychology at Case Western Reserve University in Cleveland. --- # Understanding the Nature of Autism: # Behavior and Brain Science **Travis Thompson, Ph.D.** Professor Dept of Pediatrics University of Minnesota School of Medicine --- We Will Discuss: • Why Children with ASDs Do the Things They Do • Characteristics of Autism: The Core Deficits • Lack of Understanding of, and Skill with Communication • Brain Basis of Social Deficits • Compulsivity: Brain Differences in ASDs --- # Why Do Children with ASDs Do the Things They Do? • It helps to try to see the world through their eyes • They are doing the best they can to make sense of a disorderly world that causes them frequent distress --- # Characteristics of Autism: ## The Core Deficits • Communication Deficit • Social Deficit • Compulsive Disorder: Fixed Interests & Repetitive Behavior --- # Deficit in Communication as Problem Solving Tool - Fail to grasp the idea that communication is a problem solving tool - Slow language processing: Poor synchronization across brain’s language areas - Difficulty with pragmatics --- # Fail to Understand Social Cues - Don’t look at people’s eyes, as early as 6 months of age - Lack amygdala and prefrontal cortex activation to faces exhibiting emotions - Little response of fusiform gyrus to faces - Mirror neuron deficits-inability to understand gestures - Unable to draw social inferences --- # Eye and Facial Processing Deficits - As early as 6 months, children who are later diagnosed with an ASD fail to look at eyes - There is little or no amygdala and prefrontal cortex activation to eyes --- # Fusiform Gyrus and Mirror Neuron Dysfunction - Fusiform “face area” under temporal lobe does not activate to faces - Mirror neuron system required for understanding gestures is dysfunctional --- # Are faces special? - People can often recognize objects regardless of orientation, but upside-down faces are much more difficult to recognize - Recent research has examined what exactly drives this area’s activation – This research suggests that not just face processing but rather people’s expertise (i.e. experience) with faces underlies this activation --- # Developmental Hypothesis of Autism - Early experience with faces shapes visual cortex - Diminished social interest in children with autism: − leads to lessened attention to people (faces) during critical early developmental periods − failure to develop expertise for faces --- # Predicting Severity of Social Deficit from Amount of FFA Activation during Face Perception Tasks --- # Fusiform Face Area Activity to Faces Predicts Actual Face Recognition **r = .59,** ***p = .0001 (N = 47 )*** --- # Fusiform Face Area Activity to Faces Predicts Severity of Social Disability Across Diagnoses - Research also indicates that the more social deficits individuals with an autism spectrum disorder have, the less the Fusiform Face Area will activate --- # Implications - Lack of Fusiform Face Area activation is directly proportional to degree of impairment and therefore: - Fusiform gyrus function is a good target outcome variable for a treatment study --- # Fixed Interests & Repetitive Behavior *“The child’s behavior is governed by an anxiously obsessive desire for sameness that nobody but the child himself may disrupt on rare occasions. Changes in routine, of furniture arrangement, of a pattern, or the order in which everyday acts are carried out, can drive him to despair.”* **Leo Kanner, 1943** --- # Preference for Things - Preference for objects that are constant…predictable --- # Making the World More Predictable • Use visual schedules • Give a warning before there will be a change in routine • If possible, give the child a say in which things are done in what order --- # Gain Control by Relinquishing Control - Teach legitimate means of requesting control over things important to the child but not very important to caregivers - Choices-Mother: “Would like like apple sauce or pudding for dessert?” - Child: “No! I don’t want to do spelling!” Teacher: “OK, let’s finish coloring, then we’ll do your spelling.” --- # Epilogue: The Little Stranger in Our Midst - Teachers and parents look at a child with autism and see a little stranger in their midst. What makes him so different? - It’s up to us to help them. We usually can do so if we see the world from their vantage point and apply sound basic intervention practices. --- # Making Sense of Autism Learn much more about the topics discussed in today’s webinar in Dr. Thompson’s new book Making Sense of Autism—the authoritative guide for non-experts. --- # Thank You for Attending! - Check your e-mail in the next day or two for a link to a recording of this webinar that you can access any time - You can find a copy of today’s slides at www.brookespublishing.com/autism
