Junior and senior high school students from Ithaca Youth Bureau’s College Discovery Program visited the Department of Human Development to learn about college, research, and concussions from members of Dr. Valerie Reyna's Laboratory for Rational Decision Making (LRDM).

The middle schoolers attended a concussion and the brain workshop on July 17th at the LRDM lab in Martha Van Rensselaer Hall led by David Garavito (JD/PhD) and Joseph DeTello '18. The group participated in a research project on concussions and decision-making and then took part in an interactive program about concussions. Students shook eggs to demonstrate how you don’t need to crack a shell (their skulls) to damage a yoke (their brains). Then they compressed and stretched gelatin brains to see how diffuse damage to neural fibers (axons) in the brain can occur after the impact of a concussion.

Allison Franz '18 got the group moving with a game of “blob tag". In this game, a group of students form a “blob” and try to tag other students without letting go of each others’ hands. The tagged students then became part of the blob. As the blob grew and people pulled in different directions, the blob would break apart and lose the tagged players. This is similar to what occurs when there is a blow to the skull and the skull comes to a fast stop - the brain moves in different directions and the neural fibers break resulting in diffuse damage to the neuronal axons.

The high school students attended the second brain and concussion workshop in the LRDM lab on August 16th. They participated in the concussion and decision-making project followed by a hands-on demonstration of concussion risks even when wearing helmets. The students loved creating their own "helmets” to protect eggs which were dropped from a great height. They learned that not only did they need to protect the egg from hitting the ground, they also needed to slow the momentum of the egg. This is a very important lesson to learn, as there is often a false sense of security when wearing a helmet in sports like football. Although the skull may be protected by a helmet, an abrupt momentum shift causes the brain to keep moving, resulting in the brain hitting the skull and a concussion.

The group also visited the HD EEG and Psychophysiology (HEP) Laboratory. James Jones-Rounds, HEP manager, the lab equipment used for gathering data about electrical activity of the brain, electrical characteristics of the skin, and measurement of eye activity. Many of the students volunteered to be in the demonstration - one student even tried on the mobile EEG headset and managed to move a box on a computer screen using her mind!

We gratefully acknowledge Engaged Cornell for funding the Engaged Risky Decision Making project which supports our research and outreach with adolescents on the risks of sports-related concussions.

What does your lab study?

Annie Erickson ’16: Our lab is interested in studying the neural basis of cognitive processes such as attention, learning, and memory. To investigate these complex neural mechanisms, we use a cross-species approach studying both human and animals. We are interested in the neurochemicals that modulate cognition— specifically, a neurotransmitter called acetylcholine. My project focuses on the effect of acute and chronic caffeine intake on cognition in rats, testing whether caffeine can rescue cognitive deficits that have been induced by blocking acetylcholine.

Why study caffeine?

Eve De Rosa, Associate Professor of Human Development and Rebecca Q. and James C. Morgan Sesquicentennial Fellow: We all drink coffee, but we don’t always give deep thought to how it affects attention, learning, and memory. That’s why I love the real-world importance of Annie’s honors thesis question. She’s finding cognitive tasks that both rats and humans can perform so that we can translate the basic science experiments in the lab to our understanding of human cognition.

What do you like about this work?

Erickson: After following this project from conception to experimental setup to final execution, it’ll be incredibly exciting to see the results. It’s been inspiring to work with Eve, and to see the way she’s able to balance research, teaching, and family. She’s so enthusiastic and positive, and I really enjoy discussing my ideas with her, because she’s always so encouraging.

De Rosa: I love mentoring students like Annie! After participating in the lab as an undergrad research assistant, she approached me with this wonderful question about looking at caffeine’s ability to boost cognition, and whether it was caffeine’s interaction with acetylcholine that underlies this ability.

The fact that caffeine is a cognitive enhancer is something I was already aware of, but not that it might be important in slowing the decline of pathological cognitive aging, like in Alzheimer’s disease. When Annie brought that idea to me, I could see why it might be worth taking a chance to pursue the question.

What’s the risk?

De Rosa: Rat neuroscience is expensive, and it’s not my primary research focus. I’m very interested in acetylcholine, which declines during normal aging, and in using functional Magnetic Resonance Imaging to assess brain activity. But Annie’s research is something I would never have pursued on my own. And now I’m having so much fun reading the literature, thinking about how it relates to my larger research vision.

Erickson: Through the process of developing my independent project, Eve has provided crucial advice while also being incredibly flexible in letting me explore different ideas. She’s shown how important collaboration is for successful research and I’ve learned so much about thinking and writing scientifically—skills that are fundamental to a future in research.

In 2015, Annie Erickson received the Human Ecology Undergraduate Summer Research Stipend, and is currently working toward an honors thesis funded by the Human Ecology Alumni Association

This summer, I’ve had the pleasure of combining the ultimate camp experience with the experience of working in a laboratory and conducting exciting, cutting-edge in-field research on decision making. The project, Health and the Brain Neuroscience Outreach, is a Cornell Cooperative Extension internship under the direction of Dr. Valerie Reyna. The mission of the CCE internship program is to translate and apply Cornell research in ways that can benefit communities all around New York State.

In late March, I joined Dr. Reyna’s Laboratory for Rational Decision Making as a member of the Health and Medical Decision Making Team, whose goal is to use research on decision making to help educators and medical professionals effectively use theory-based interventions and communicate risks to patients. Using the information they’ve effectively learned, these patients can then make informed decisions about their health.

My first task of the project was to update the curricula taught to middle school students in past years at 4-H Camp Bristol Hills, in Canandaigua, New York. Looking at two modules, Nutrition & Neuroscience and Genetics & Neuroscience. The goal of teaching both curricula was to help students better understand obesity prevention and genetic risk using theory and evidence-based methods.

The curricula were based on Dr. Reyna’s research on decision-making and the importance of incorporating “gist” (a fuzzy or vague representation that contrasts with a precise verbatim representation) into the lesson plans in order to see the effectiveness of a gist-enhanced curriculum. According to Fuzzy-Trace Theory, people tend to rely on gist (bottom-line meaning) rather than verbatim representations (such as exact wording or specific numbers) whenever they make decisions. In teaching the campers, the goal was to see an improvement in retaining the information learned through gist when making decisions, such as deciding between eating a cupcake or eating an apple. Examples of gist-enhanced concepts are: “Developing healthy eating and exercise habits has both long-term and short-term benefits for a person’s physical and mental health,” and “Your diet should consist mostly of fruits and vegetables.”

I was extremely excited to be able to work with the campers. It’s very rewarding to be able to be the person to expose kids to new information, especially the kind that has the potential to affect their lives for the better– like knowing the nutrition concepts and science behind eating well and exercising more, or understanding more about how genetics work. By reviewing Dr. Reyna’s research, I was able to generate a list of possibilities for fun, informative, and engaging activities for the campers. In order to get a better perspective of what a camper would like (around the ages between 11-14), I talked to kids of that age to get their opinions and feedback to develop the most effective and engaging activities. I also read and dissected Dr. Reyna’s empirical research, such as A Theory of Medical Decision Making and Health: Fuzzy Trace Theory (Reyna 2008) and Efficacy of a Web-Based Intelligent Tutoring System for Communicating Genetic Risk of Breast Cancer: A Fuzzy-Trace Theory Approach (Wolfe et al. 2015), to understand the theory behind what we teach in Health and the Brain. Her past publications revolve around how humans remember and process information, which is essential to the development of activities and curriculum for the camp.

After solidifying teaching plans and curricula, I was able to generate and order a material list needed for this year’s curricula. I also started looking into data from previous years to get a better idea of the project through learning how to use IBM SPSS Statistics software. Though at times learning the program has proven to be challenging, the skill set used in statistical analyses is essential to the research process and for my future career goals. Throughout my time of preparation of Health and the Brain in the lab, I have learned much about working in the lab and interacting with not only fellow researchers, but also professionals in other fields, and had a challenging yet enjoyable time getting acquainted to it. I’ve learned that time management is key to completing the project successfully, and held many practice sessions teaching the curriculum and improving my notes and lesson plans.

My adventure at 4-H Camp Bristol Hills began with staff training, including how to mitigate bullying, report child abuse, how to effectively work with kids, and how to de-escalate situations, etc. Staff training allowed me to be well prepared when the kids come to camp in order to make sure that the kids can get the best possible camp experience, and also to get a better sense of how to best engage and recruit kids to participate in the Health and the Brain Outreach Program. During my time at camp, I stayed in a log cabin called Big Dipper, which housed me, Corrine Casal '16, Margaret Sloan'18 (both from the Adolescent Transitions Lab at Cornell), and Sophia Franck (another intern working on a social media project for the camp).  Connecting with all other counselors was very exciting, and I was able to join in on all the camp traditions, such as getting named by another counselor or fun camp songs or skits. We all use camp names at 4-H Camp Bristol Hills, and on the last day of each week, the campers try to guess our real names. My name at camp was Fence-Apella (Pella), because I fenced and sang a capella in high school! It was so inspiring to see how enthusiastic and welcoming the other counselors are to make sure the campers have the greatest time and feel comfortable at camp. The kids were so lucky to have such a diverse selection of activities, ranging from Archery and Air Riflery to Critter Care (where there are two baby white rabbits, hedgehogs, and even snakes).

After staff training came Week 1 of camp, when I finally got to meet all the bright-eyed campers! Every Sunday morning, I woke up early to drive with a graduate student from my lab to Canandaigua, New York, where 4-H Camp Bristol Hills is located. The natural beauty of the area and the camp is breathtaking, especially when the sun sets. Before each week starts, the camp staff had a potluck lunch meeting to get ready for the campers’ arrivals. Registration then began at around 1:30/2 PM for the campers. In order to recruit for the project, I set up a huge poster and table exemplifying all the fun activities and crafts we would do in Health and the Brain, and also talked to parents and campers who were waiting in line. Week after week, I became also more accustomed to and more successful in recruiting campers to participate in Health & the Brain. As an afternoon recreation activity, many campers were excited about drawing brains on swim caps and making DNA using pipe cleaners and beads, along with many other hands-on games and activities. It was so interesting to find kids who were so excited about science and wanted to sign up immediately, and to find others who were more curious and trying to find something that they felt passionate in and wanted to give science a try. After getting everything organized and settling down after the registration period, I would eat dinner with the campers. One of my favorite times during the weeks was being able to meet new kids during mealtimes and talk about their different interests, ranging from horseback riding to TV shows. At night, I would participate in a warm campfire and an evening program, where the counselors and campers get together to do all kinds of fun games with different stations to get the campers to make new friends and be comfortable being themselves at camp.

Health & the Brain had a lot of really bright and curious kids, which was very inspiring. Teaching the curricula at camp was very successful. Many of them knew so much already and had so many questions for me; I’m not sure if I even knew as much as they do when I were their age! A lot of the campers were very inquisitive about different cancer issues and genetic questions and also interested in eating healthier and exercising well. Many had a lot of prior knowledge on vitamins and minerals and where they come from, such as iron from meats and protein or calcium from dairy products. They were also very keen on wearing their “brain swim caps” into the pool and showing off their DNAs to friends. The kids told me again and again how much fun they had and how much they had learned. Many of them were excited about getting a head start in school on the different topics revolving around neuroscience, genetics, and nutrition. Hearing great answers from campers made me feel like I really made a difference in their lives. For the processed foods activity in the nutrition curriculum, the campers split up into two groups: both of them are workers at food company’s factory, but in order to emphasize the differences between highly processed and unprocessed foods, one company processes the core ingredient (styrofoam ball) highly using trans fat (clay), high fructose corn syrup (glitter glue), etc., while the other company only cuts and packages the product. This activity, while very entertaining and involves a lot of the campers’ favorite hands on materials, like clay and beads, also starts the discussion for which product represents a healthier food choice and why.

During my last week at 4-H Camp Bristol Hills, I was able to work with Science, Technology, Engineering, and Mathematics (STEM) campers. I learned that part of working in the field for research involves flexibility, which was required to work around the STEM camper’s busy schedules in order to allow them to have the opportunity to be in Health & the Brain! During Monday through Wednesday, while I worked with other resident campers, other Cornell students working with Professor Franck from the Physics department worked with the STEM campers on building radios and satellite dishes. During my time with them on Thursday and Friday, they asked so many great questions for each topic, especially neuroscience. They knew so many things about the brain that were very advanced. Many of them had watched or read a lot about the brain and knew about different parts of the brain or case studies of special brain trauma, such as memory mechanisms in the hippocampus, or Phineas Gage, the American railroad construction foreman who had an accident that damaged most of his frontal lobe.

Even though each camp session lasts only one week, being together and meeting all these new campers makes one feel very connected to the camp and the kids, especially during moments where the entire camp gets together to hold hands and sing the goodnight song together. When I had to leave at the end of each week, despite being content and proud of a great week, I also felt an underlying sense of sadness to have to leave such a beautiful community where all the kids find places to truly be themselves and find best friends. The camp environment never ceased to amaze me; the campers were brimming with enthusiasm and the counselors still managed to top it week after week. While I’m saddened by the conclusion of my time at camp, I’m also very happy to have made so many great friends, amazing memories, and learned so many things!

I want to give special thanks to Dr. Reyna, Lindsay Dower ‘17, Dr. Priscila Brust-Renck '15, Dr. Allison Hermann and Tim Davis for allowing me to have the opportunity to be a part of such an exciting outreach project. Your continued support and guidance throughout the project was a huge factor for its success. I also want to thank the staff of 4-H Camp Bristol Hills for welcoming me with open arms, supporting me, and inspiring me with their enthusiasm and hard work! My internship with CCE Health and the Brain Neuroscience Outreach at 4-H Camp Bristol Hills has been such a memorable time. I’m incredibly grateful for the wonderful experience I’ve had this summer, which has allowed me to better understand not only how scientific research labs work and learn the techniques necessary in the future for my own work, but also the opportunity to conduct actual in-field research. With my love for working with kids and being able to get the full log-cabin camp experience, my time at camp has been absolutely phenomenal. This experience has allowed me to solidify my decision to pursue clinical psychology graduate work as a career, and inspired me to take on all opportunities with enthusiasm and determination.
