Neurogaming for the Anxious Brain

Anxiety is one of the most common mental health problems facing the western world today. Individuals with autism spectrum disorders (ASD) are especially vulnerable to experiencing moderate to severe anxiety. This anxiety can take many forms such as restlessness, panic attacks, and even phobias.

The project that I am fortunate enough to be working on here at RADLAB is proposing the use of a neuromodulation approach to train individuals to relieve their anxiety and find that state of “calmness” which is associated with frontal alpha electrophysiology. We hope to reach our target audience of young individuals with ASD through neurogaming. The individuals will play a video game of our own creation, “Alpha Fish”, that is controlled by real time brainwave measurements using high density EEG. The game is based on the popular side-scroller “Flappy Bird” and it rewards the brain states associated with “calm”. We hypothesize that this will be a fun way to train individuals who play it to consciously control those brain states.

The control of these brain states is focused around the alpha brain wave. So called “frontal alpha” is associated with attentional suppression mechanisms (Foxe & Snyder, 2011) and may be observed in individuals who practice meditation (Cahn & Polich, 2006; Kasamatsu & Hirai, 1966). This link with meditation drives the hypothesis that training frontal alpha may give some of the same mental health benefits as meditation and the potential for additional training to specifically target anxiety. Additionally, alpha waves can be observed on the central midline and are readily accessible to EEG recordings; by staying away from facial and neck muscles and focusing on a specific frequency band, we avoid the majority of muscle movement interference.

You might be wondering, aren’t there drugs for anxiety and panic attacks? Well yes, there are certain pills one could take that can be effective and it is certainly an option. However, the hope is that instead of treating anxiety through pharmaceutical approaches that can incur unacceptable side effects and significant costs for the families, we can utilize this alternative therapy to provide a cheaper and less invasive solution. I feel that this is an especially important aspect of the project considering the state of pharmaceutical dependence we are in as a country. As a pre-med undergraduate here at UCSD, I am constantly hearing and learning about the drug dependence and opioid crisis the medical field is facing. Any step towards lowering the unnecessary amounts of foreign substances this country ingests is a step in the right direction.

Currently, “Alpha Fish” is still in the developmental stages, but we hope to get to subject testing very soon.

PoNG Center @ QI

We've just the launch of our new Power of NeuroGaming (PoNG; we thought it was pretty clever) Center at UCSD's Qualcomm Institute in Atkinson Hall. The PoNG Center is a collaborative technology center with experts and resources available to anyone doing game-based research, from engineering to medicine, behavior therapies to skill building. Speaking of skill building, through the PoNG Center and with help from the San Diego Foundation, we have taken on the awesome and humbling task of providing an internship for up to 25 young adults on the autism spectrum. These students, who have graduated from high school with or without college experience, will spend 8 weeks at RADLab and the PoNG Center at a STEM focused tech-based fellowship. Here, they will acquire and hone video game development skills like computer coding, digital art, and project management. But they will also be paired with coaches and mentors that will develop the soft skills needed to thrive in a mainstream work environment. This is part of an initiative close to our hearts to increase the currently dismal employment rates of individuals with autism and ASD. Stay tuned for amazing things!!

PoNG Center Internship

Calling all video game programmers, developers, artists, and enthusiasts!! We seek to directly engage a group of individuals who are underrepresented in the STEM workforce--individuals with developmental disorders, specifically Autism Spectrum Disorders--in a summer supported internship program. The PoNG Center is a UCSD research group (led by RADLab’s Leanne Chukoskie) that provides technology, programming, and other game-based resources to groups researching a wide variety of topics. We believe that turning data collection into a game is an effective way to engage participants and involve the community in real world solutions.

    The Key to a Healthy Relationship

    Here at RADLab, we are scientists. We are also community members and, by nature, a community-oriented organization. Therefore, we strive to convey our mission of science to our community audience. And how do we do this? Communication, communication, communication. This is especially important in autism research, which can be an inflammatory topic. But this is something that we hope all scientists are striving for, regardless of their field of study. Through open dialogue with the community and diligently, clearly conveyed messages we can lift the veil of mystery and uncertainty behind scientific discovery, as well as open our minds and hearts to what people in our community think and feel.

    In the spirit of this mission, check out this article about a recently held Communicating Science workshop (ComSciCon) at UCSD. It’s not just a nice idea, today's scientists and community leaders are putting good communication into action!

      Dare to Be Aware

      As we wrap up the month of April, Autism Awareness Month, we are reflecting on just what awareness means. In a world where there are all sorts of things that, unfortunately, need awareness risen about them it means fundraiser walks, community events, brightly colored bracelets, and pledge drives. Frankly, “awareness” often comes in the form of asking, even begging, for (much needed) funds to tackle an ongoing issue. So we walk our walks, dig into our pockets, and feel good about helping our community. Sure, we know that there are problems out there, but how much do we really know?

      Awareness (n.): the state or condition of being aware; having knowledge, consciousness. In the true spirit of awareness there is always more we can learn.

      Autism Speaks, an autism advocacy organization that also promotes research, has just released a report about autism and health. Many of us are already aware of the signs and symptoms, but Autism and Health* explores the very real obstacles faced uniquely by individuals with ASD and their families. The saying “When you’ve met one person with autism, you’ve met ONE PERSON with autism” rings so true in our community precisely because autism presents in many different ways and frequently together with other disorders. Never mind fake news, this facts and figures report outlines health issues common to the autism community as well as realistic and effective solutions to these treatable, and sometimes preventable, challenges.

      Check out more links about health and autism listed at the end of the report for insight into specific issues. And awareness is knowledge, keep learning!!

        Building Stronger Communities to Support Young Adults with ASD

        RADLab research scientist Dr. Leanne Chukoskie has her hands in many projects as well as one very special glove. Dubbed the “Rady Glove” based on UCSD’s collaboration with Rady Children’s Hospital, this sensor-filled glove is designed to take measurement of a person’s muscle strength. These types of measurement have been previously performed by doctors and clinicians, and are subject to the inaccuracies of human error judgments. The glove’s ability to quantify muscle strength measurements through computer algorithms offers an opportunity for consistent and reliable data that directly impacts the diagnosis and treatment of patients.



        For more about the glove and RADLab’s contribution to the collaboration, check out the story from the San Diego Union Tribune.

          Building Stronger Communities to Support Young Adults with ASD

          When I arrived to set up the computer, I was met with a vast array of cheerful amusements in this young persons’ room—posters of favorite game and cartoon characters, a fast PC for gaming, and several stuffed animals. It was a cozy place to hang out, which is a good thing, as I learned that Alan* spent most of his days there—alone—now that he was no longer taking Community College classes. Variations on this theme recurred with each home visit I made to young adults on the autism spectrum participating in our video game attention training study. Many of these young people are passionate about video gaming and contribute to online discussions of new and classic games. Some write fan fiction. Others dabble in programming to make their own video games and still others create digital animations making use of the broad array of resources available for learning such things with just an internet connection. Yet at home they sit, with obvious talent and a desire to learn but no clear path to employment or further training. A few manage college classes either full time or part time, but the vast majority are stuck in a holding pattern, in need of support that doesn’t seem to exist.

          A recent article in Spectrum describes this situation in greater detail and especially the effect of the so-called “services cliff” on young adults like Alan. What feels like adequate support through high school drops off suddenly thereafter, just at the point where specific support is needed to transition into independent adult living. This is a challenge that affects individuals across the breadth of the autism spectrum. However, ironically, it is those with normal to high intelligence who despite appearing to be more employable at a wider range of jobs actually fare worse at finding and keeping even low-wage, part-time employment.

          Make no mistake, the Spectrum article does not paint a pretty picture for young adults across the spectrum. But just as any two individuals with ASD likely have very different needs for support as young adults, the solutions that are just right for each community are also unique. This is why we need to come together as members of the San Diego autism community to listen to each other’s needs and work together to turn the “cliff” into a much more gentle slope. To this end, on Wednesday evening, April 5th, there are two events that take a first step at nurturing those community connections. UC San Diego is hosting a screening of Bass Clef Bliss, which tells the story of how one young man with autism found community around a love for music.

          San Diego State University will be hosting a panel discussion with three young adults on the spectrum who are currently in college and share their stories of their young lives [see flyer]. The SDSU event will also celebrate autism awareness month by lighting Hepner Hall blue. A few pieces to the puzzle of young adult support exist, though not as prominently as we need them. The National Foundation for Autism Research (NFAR) has created a Tech Training program for young adults in San Diego. This seven-month long program provides young adults with training for a career in quality assurance—basically finding and documenting the bugs in new software and hardware to assist developers in delivering bug-free creations. The graduates from this program leave with more than technical skills. They also engage in a soft skills program to enhance their ability to succeed in any workplace—including establishing useful habits of mind for workplace success, learning how to talk to one’s boss, proper meeting etiquette, etc.

          Another ambitious, though unfortunately not local, program has recognized the value that exists around a University—lots of housing, a wide array of employment possibilities, public transportation and shopping options, and a community with lots of enthusiastic young people who can serve as residential advisors and companions in social activities. Funded by a generous donor at Rutgers University in central New Jersey, the plan is to provide housing and community engagement for young adults with ASD along with supported job placement. The Spectrum article also talks about another program just getting underway at Drexel University in Philadelphia. How can we leverage the resources of universities and colleges here in San Diego to better support young adults with ASD? Recent autism tracking data tell us that 50,000 individuals will ASD will reach age 18 each year. For San Diego County, with approximately 3.2 million people, can expect to have about 500 individuals with ASD reaching age 18 each year. We all lose out when these individuals don’t find meaningful paths to employment and a supportive community. I hope you will find a way to connect with others in our community this Autism Awareness month and through your discussions create new ideas for supporting young adults with ASD.

          *Our young research participant’s name isn’t really Alan, but the situation I describe is quite real.

            Friendly Neighbors There, That's Where We Meet

            I had no inclination that the trajectory of my life would have brought me where I am today. That must be true for most people. But when I started college as a doe-eyed, goody two shoes, straight-A student, academic decathlete, and marching band leader, I had no idea that I would have NO idea what I was doing when I took on a new job at the age of 30.

            Autism. I didn’t have it, no one in my family had it, my child didn’t have it, and no friends or friends’ families had it. I didn’t study it in school, I was no school psychologist, and what minimal amount of child development I was exposed to was only about typically developing kids (Piaget, anyone?). What business did I have in convincing an autism research lab that I was useful to them in any way? I guess I was going to force my way in.

            But, surprise! The autism community didn’t need to be forced, it welcomed me. It said “I know you’re new to this now, but that’s ok”. Each day I spent in the lab taught me new things about a word I heard often on the news or read on some angry internet post, but did not give my attention to. My new vocabulary included phrases like “on the spectrum”, “PDD”, “restricted and repetitive behavior”, “IEP”, and “services”. I got to know kids, parents, siblings, adults, researchers, activists, and organizers who all smiled at me warmly and trusted me. I learned how different each interaction could be. I learned how different each treatment or combination of interventions could be. My eyes and my heart were open. I discovered just how much connection I had with autism that I wasn’t even aware of.

            The autism community didn’t need me, but I needed them. I needed them to show me that I could understand this disorder, that I could be useful, that I could make an impact. Every time I feel like my job is mundane, I remember that every copy I make, every participant I schedule, every dataset I analyze goes towards helping these wonderful, brilliant families. My name is Sarah Hacker, I’m a research associate at RADLab, and the autism community is my community.

            As researchers of a specific population, we really get to know our participants and their families. We feel obliged and privileged to be part of their community, to advocate for them, to impact their world as positively as we can. To see how you can make an impact, even in the smallest way, check out these opportunities.

            • On Saturday morning, March 25th, the National Foundation for Autism Research (NFAR) is having its annual Race for Autism at Balboa Park. As always, it's superhero themed!! Complete with a resource fair and plenty of family activities, it's an awesome way to get out and support autism research. If you're not inclined to run/walk or can't make it down, consider donating to NFAR through Team RADLab.

             Team RADLab represented well at NFAR's Race for Autism. Complete with researchers, students, and families!

            • In honor of Autism Awareness Month, a special screening of Bass Clef Bliss: Terrence's Path will show at UCSD. This inspirational story of an autistic man finding his way in life through music is a free event open to the public. Meet the filmmakers and enjoy this great community outreach event on Wednesday, April 5th at the Price Center Theater.
            • Less of an event and more of a demonstration of community on a grander scale, keep a look out for something new coming to Sesame Street; a puppet named Julia who has autism. Read this article to find out more about a new friend and the story of a mother who was called to bring her to life. Cheers to PBS as well for celebrating Autism Awareness Month by introducing yet another character on the spectrum to the show Arthur.

            As Autism Awareness Month begins in April, we are reminded that it is our differences that make us amazing. Here's to celebrating both the differences as well as all that we share in San Diego's autism community.

              Say "Hello" to my Digital Friend!!

              Interventions based on novel technologies are often useful for and appealing to children with autism (1).  Our lab and others have been using video games for training and assessment. In addition to video games, robots have been developed that aim to support social interaction in individuals on the spectrum (2-4).  Our colleagues at the University of California, Irvine Jeff Krichmar and Ting-Shou Chou developed a tactile robot CARBO (short for Caretaker Robot).  CARBO has a smooth shell that is covered with trackballs (remember Blackberry phones?) that light up a different color depending on the direction they are moved.  

              CARBO was first brought to us to determine if children with ASD would have improved sensory and motor function through repeated sessions with CARBO.  I, being a neuroscience student, was intrigued by the idea that a robot may be able to help with these behaviors. During the first round of sessions I had with CARBO, I found myself less worried about their sensory and motor behavior, but more about whether or not they were having fun.  And they were! Through comparisons of participants’ behavior during the CARBO session and previously recorded structured interview sessions involving toys, we observed that CARBO interactions seemed to enhance social engagement.  This lead us to change our course of action from recording change in sensory and motor behavior over repeated sessions with CARBO to change in social engagement over repeated sessions with CARBO. 

              We are now testing a comparison between playing with CARBO and playing an interactive game. This change got me even more excited about the project, because now I get to meet new people and relate with them because I’m really a child trapped in young man’s body. After each interaction, I code the resulting video marking instances of social interaction, speech and repetitive behaviors when they occur.   This coding allows us to quantify and compare behaviors in each phase of the interaction.  In May, CARBO will make his San Francisco debut to participate in the IMFAR Innovative Technologies Demonstration.  We look forward to sharing CARBO and our results as well as getting feedback from the broader autism community.

                  10 Tips for Navigating an Individualized Education Plan (IEP) Meeting

                  As a graduate student completing training to be a speech-language pathologist, I completed a clinical rotation at a local elementary school and contributed to Individualized Education Plans (IEPs) for children demonstrating a wide variety of communication needs, including children on the autism spectrum.

                  Though my classes and clinical training prepared me for the IEP process, the hands-on experience of participating in these meetings was a massive learning experience for me. I hope that some of what I have learned will be helpful and interesting to families that are working with their children’s schools to develop their own IEPs. The following is a brief list of tips and suggestions for approaching your next IEP meeting.

                  1. Remember that you are an important member of the IEP team! While other members of the IEP team have expertise in education, communication, physical development and more, you are an expert on your child. You have valuable information about your child’s skills that cannot be provided by anyone else.

                  2. Get to know the team! IEP team members can include the general education teacher, education specialists, speech-language pathologists, occupational therapists and more. Each person is dedicated to supporting your child in unique—but often related—areas. Understanding who is responsible for what helps you direct comments and questions to the appropriate team member.

                  3. Understand your child’s options for services. As the name implies, each child’s education plan is individualized, or tailored to their needs. This individualization includes varying levels of support, as well as varying contexts for those services. For example, services can be provided in the context of their general education classrooms. These are called “push in” services. Alternately, children may work with the specialists in separate classrooms, either individually or in small groups. These are called “pull out” services because the child is pulled from his or her classroom. Finally, children may spend portions of the day or full days in special education classrooms. Discuss your child’s areas of strength and areas of need with the team to determine which of these options best fits your child’s needs.

                  4. Familiarize yourself with the IEP document. Written IEPs can be lengthy documents—knowing types of information to expect helps you follow information presented during the meeting. Information included in IEPs includes—but is not limited to—the following:
                   a. Current performance reflects how the child is currently performing in school. Information is collected through a review of the child’s schoolwork, formal and informal assessments administered by IEP team members, and observations made by the team members. It can be helpful to you to know the tools that were used to determine your child’s level of performance. It is also important to consider whether the profile painted by the team matches your expectations, and to give them feedback (see Tip #6!).

                  b. Annual goals. Two sets of goals will be discussed at the meeting. First, you should hear about your child’s progress based on the annual goals established at the previous IEP meeting. Second, new annual goals for the coming year should be presented. Your child’s goals dictate the skills that are targeted most heavily during services, so they are an incredibly important component of the IEP meeting and document. Goals should target areas of weakness that are identified by team, including you! Strong goals are also measurable. It is helpful to ask the team members how exactly they will determine when your child has met his or her goal.

                  c. Service delivery. The document should clearly describe your child’s services, including how often they will be provided and how long they will last. For example, you might hear that your child will receive 26 hours of speech and language services per year in a separate classroom. It is helpful to ask what this means for them on a weekly basis. For example, how often are they being pulled out of their general education classroom?
                  5. Remember that this document is only a draft! The meeting is an opportunity for the IEP team—including you—to engage in a conversation about the proposed plan for your child. Based on the discussions at that meeting, any number of revisions may be proposed and approved. For example, if you have a specific area of concern that is not addressed in the IEP, you can suggest that a goal be added to your child’s plan. You can also ask that goals be altered, or removed.

                  6. Comment and ask questions throughout the meeting. There are many specific terms associated with service delivery and educational settings that may not be familiar to you—it is always appropriate to ask other members of the team to clarify what they mean. It is also appropriate to ask any other questions that come to mind—how was the child’s progress monitored? What tools were used to determine his or her current levels of performance? Why were these goals selected?

                  7. Come prepared. It is helpful to organize your thoughts about your child’s areas of strength and weakness going in to the meeting. You may want to review your child’s previous IEP document to review their previous goals and help you consider the progress that has been made in the past year (Your child’s school should be able to provide those documents at any time!) It may also be helpful to brainstorm with trusted individuals that know your child.

                  Preparing notes for the meeting may help you make sure that all of your ideas are communicated when you meet with the team. You may also want to bring relevant medical records or examples of your child’s performance (like written materials, or audio/video recordings) that demonstrate his/her strengths or your concerns.

                  8. Sign the document only when you are ready. The IEP document details the plans for your child for the coming year, and you may wish to take more time to review it. Though it is possible to sign and approve the document at the end of the meeting, you are also able to take the document home to review it more carefully or to share it with others before approving it. Further modifications, should you want them, would also be possible.

                  9. Consider bringing a trusted person with you. If you would like, it is possible to have a trusted friend, family member or other service provider sit in on the meeting to provide an additional perspective on your child’s needs. If you plan on someone attending the meeting with you, it is helpful to let your school know.

                  10. Ask for accommodations. Efforts can be made for you and your child to have a more successful IEP process. Particularly in the case of culturally and linguistically families, accommodations are necessary.

                  For example, if your family speaks a language other than English at home, it is important that your child’s skills in each language are accounted for. Additionally, if you would like an interpreter present, the school is required to provide one.

                  Classroom Benefits of Aerobic Activity

                  Our doctors and other public health officials regularly remind us of the importance of exercise for both short- and long-term health benefits. As a scientist, I am fond of pointing folks to studies linking aerobic exercise and memory improvements including numerous studies in both animal models and humans. What may be less obvious are the links between physical activity in kids and the kind of attentive classroom behavior needed for learning.

                  A study was published recently in Pediatrics detailing the positive effects of aerobic cycling on behavioral self-regulation and classroom functioning among children with behavioral health disorders, such as autism, ADHD, anxiety and mood disorders. There are several reasons why I find this important. First, children with behavioral health disorders tend to participate less in aerobic exercise. Second, although there is ample research demonstrating the links between exercise and mood and behavioral improvements, much less research speaks directly to how that works in an educational setting and even less in kids with behavioral health disorders (note that this study was conducted in a K-10 school specifically for kids with behavioral health disorders). Third, the authors note that adaptive physical education activities often aim for laudable goals such as improved social skills, teamwork and motor skill development, but do so to the detriment of longer bouts of aerobic exercise. For each of these reasons, it is useful to study the effects of aerobic activity on school-related behaviors in children with behavioral health disorders.

                  The scientists found improved behavioral regulation, and reduced impulsivity and frequency of mood swings on the cycling days. Importantly, the same effect was observed, but to a lesser degree, during the rest of the cycling activity weeks. This kind of study is particularly nice because it uses something called a crossover design. All of the kids in the school (save for one with a medical exemption) participated in the study. Half of the kids had the cycling intervention in the Fall, while the other had standard physical education class, and then the groups switched in the Spring. This kind of design increases the likelihood that the effects observed are actually due to the intervention itself and not some accident of random assignment of kids to each group.

                  How can we use what we’ve learned from research to benefit our children? Physical education in schools is essential, and so is recess. The substantial reduction in time out of class for behavioral issues as well as improvements in self-regulation on the day of the aerobic exercise suggests that the kid who needs to move the most may be the kid who is sitting it out, having lost his recess privilege for his inability to regulate his behavior earlier in the day. Withholding physical activity is likely to lead to an even worse afternoon for that child. Given these data, perhaps it is worth finding another way to remediate behavior that would benefit the child, the teacher, and the rest of the class. Remember that the study also showed behavioral benefits for the rest of the week, not just PE days. Furthermore, finding ways to increase a child’s physical activity outside of school can also improve behavioral performance in school.

                  I will admit that my kids get a lot more exercise than my husband or I do. However, we do like to hike, climb, and bike together. At home we also play ping-pong and Just Dance for the Wii. Now it’s your turn. What are your favorite activities to get aerobic exercise for you and your child? If you don’t have one yet, perhaps some suggestions from the community will bring new ideas to get your family up and moving, and quite possibly also more “on task” in school and work.

                  Gaze Contingent Games for Vision Therapy

                  Optimal vision is not defined as seeing 20/20; rather it is the ability to successfully coordinate and control eye movements to achieve visual fluency in a dynamic environment. Currently,vision therapy utilizes various tools to address vision problems such as convergence insufficiency, ocularmotor control, and eye movements (saccades and smooth pursuit). Past studies have found that vision therapy is most successful when office-based vision therapy is paired with supplementary home training. Office-based vision therapy sessions can range from thirty minutes to one hour in duration on a weekly basis, but is highly dependent on the individualized plan recommended by the optometrist. Depending on the diagnosis, home training can vary, but most require a commitment of thirty minutes a day for five days a week. At the end of the training plan, the optometrist conducts an evaluation examination, assessing patient progress.

                  As an undergraduate student at a major research university and future optometrist, I am interested in gaining insight on how we can develop more sophisticated and effective game-based technology to support active vision in a broad range of vision therapy patients. Utilizing the attention training games already developed by the Research on Autism and Development Lab (RADLab), we will collaborate with a local optometrist, Claude Valenti, O.D., specializing in vision therapy to identify attributes of our games that align with the goals of vision training.

                  Our current study with individuals in the autism spectrum is an eight-week attention training study, with pre- and post-training evaluations. The games are designed to improve attention orienting and are played using a portable video-based eye-tracking device, which allows individuals to use their eyes to play. The portable eye tracker and others like it are inexpensive devices (approximately $100-200) that enable us to engage participants in play at home. For evaluations of training effectiveness, we use a lab-based eye tracker that can detect even very small movements accurately and with better timing precision (but with a much larger price tag). We also working with a new glasses-style eye tracker that would support this sort of gaze-contingent game play for individuals who have difficulty establishing and keeping the still posture needed for the portable eye tracker.

                  By working closely with Dr. Valenti and his team, we hope to develop both new games and new eye-tracking methods for playing them that would benefit a wider range of clinical populations. As a recent recipient of a competitive Frontiers in Innovation Scholars Program (FISP) award from UC San Diego, and also someone who will begin optometry school in the Fall, I see engaging in this sort of interdisciplinary research as crucial for the advancement of both cognitive neuroscience and optometry fields. I hope to integrate gaze-contingent methods into my own behavioral optometry practice some day, providing families an objective way to improve skills both at home and at the office. I also hope that this sort of collaborative research can either create or refute support for vision therapy, which currently lacks a strong empirical evidence base as a therapy for disorders of learning and reading. We need to collaborate in order to devise the kind of studies that will test vision therapy in individuals who are still developing and using active vision to understand the world around them.

                  TWO RADLab Undergrads

                  Receive FISP Awards

                  RADLab is proud to announce that not one, but TWO, of its undergraduates have received a FISP award to engage in student-centered research. Each student will receive funds from the UCSD Frontiers of Innovation Scholars Program (FISP) symposium at UC San Diego to perform research designed to enrich human life and society.

                  Jackie Nguyen will be investigating gaze-contingent games for vision therapy in diverse populations, which also follows the trajectory of her career path as she prepares to study and practice vision therapy via Optometry school. See a more in depth explanation of Jackie’s study in our blog.

                  Ryan Spence will be researching the effects of robot interaction as an intermediary to improve sensory and motor behavior in children with ASD. To find out more about our robot, CARBO, and the study, check out the recruitment page.

                  Joint Doctoral Student presents at FISP Symposium

                  4th year JD Language and Communicative Disorders student, Irina Potapova, presented her research at the UCSD Frontiers of Innovation Scholars Program (FISP) symposium at UC San Diego on October 18th. The FISP symposium is a celebration of awards made for undergraduate, graduate, and post-doctoral research that is interdisciplinary in nature and involving mentors from at least two divisions at UC San Diego. Ms. Potapova was awarded a graduate fellowship to work with Leanne Chukoskie and Jeanne Townsend to use eye tracking as a sensitive online assessment of novel word learning in young children both with and without language disorders.
