Perception, Language and Attention in Youth (PLAY) Lab

The newly-founded Perception, Language and Attention in Youth (PLAY) Lab's aim is to understand how early sensory experiences shape our visual, cognitive, and language abilities later in life. We study how deaf and hearing children learn through visual sign language, with the goal of understanding human cognition and learning more broadly. We compare behaviors and abilities of deaf and hearing people -- across all ages -- who use signed or spoken language.

Current Research Projects

NSF Research Traineeship

Dr. Bosworth is a member of the faculty team of the AWARE-AI NSF Research Traineeship Program. Graduate students from associated RIT Ph.D. and MS programs are invited to review information on how to apply and benefits for Trainees at our NSF Research Traineeship website. Women, Deaf or Hard-of-Hearing, and African American, Latino/a American, or Native American students are especially encouraged to apply. A video describing the program in ASL is available here.

Earn Course Credit as an Undergraduate Research Assistant in the Lab

Undergraduate students can obtain research experience for course credit toward electives working in the SPaCE Center. The Center is made up of several labs, including deaf x lab directed by Dr. Dye, NTID PLAY Lab directed by Dr. Bosworth, and the PAW Lab directed by Dr. Fitch. This opportunity provides exposure to a variety of methods used in psychological research, including behavioral experiments (measuring response time and accuracy), eye tracking, EEG, and observational studies. This is a two-semester commitment. This is ideal for NTID or RIT students who have majors related to psychology, cognitive science, language sciences, or computer science. Graduate students are also encouraged to apply using this form. Click here to complete an online form to apply.

Our Founder/Director

Rain Bosworth

Dr. Rain Bosworth is an assistant professor in Department of Liberal Studies at RIT/NTID. She is an experimental psychologist, studying development of perception and language in deaf and hearing children using eye-tracking at the newly-founded Perception, Language and Attention in Youth (PLAY) Lab. She got her PhD from the University of California, San Diego, studying visual motion processing and attention in deaf adults. She is currently investigating gaze behavior in infants and children while they watch stories in American Sign Language (ASL). The broad aim is to understand how early sensory input shapes perception, cognition, and language processing.

Our Research Team

Karen has a master’s degree in deaf rehabilitation counseling from Northern Illinois University. She is the founder and past President of Illinois Hands & Voices and A board member of New York Hands & Voices. She is also an adjunct instructor at RIT teaching a wellness course called “Finding your Passion.” Karen is the author of multiple books, including The Parenting Journey; Raising Deaf and Hard of Hearing Children, Unwrapping Your Passion, and The Passionate Lives of Deaf and Hard of Hearing People. For fun, Karen can be found water skiing on her bare feet.
Adrita Arefin holding her daughter. Adrita Arefin is currently a first year grad student of the Human-Computer Interaction Masters Program at RIT. She graduated with a BS in Computer Engineering from RIT, and shortly after, she worked for the Department of Defense in Philadelphia as a Computer Engineer in the Cybersecurity Department. After working there for some time, she realized that she was missing the “human touch” in her career, and thus decided to combine psychology with technology. Adrita is proud mother of her 1 year old daughter Arya. This inspired her to learn more about how digital media and iPad technology impacts infants’ cognitive development.

NTID PLAY Lab First Ever “Brainy Day"

The NTID PLAY Lab hosted the first ever “Brainy Day, Science-as-Play” community event at the Rochester School for the Deaf. Families with Deaf and Hard of Hearing children participated in various fun activities, related to neuroscience and the brain.  They made brain hats out of paper, learn about neurons, squeeze squishie brains, and were able to see their own brains in action with an EEG brain recording machine.  

Families were able to meet deaf scientist Victoria Popov, who is a PhD candidate in Neuroscience at the University of Rochester.  “Brainy day allowed me to be humbled by interacting with families and children who are excited about the future of science,” said Victoria. 

“Brainy Day was an engaging hands-on event—it was fun watching my son being able to connect with Deaf scientists,” said Byron Behm, parent of a deaf son.

Special thanks to the students from the NTID Master’s in Secondary Education (MSSE) who volunteered for the day’s event.  For them, the event was equally as fun to see the curious eyes and wide smiles from babies to teens.  “What an enjoyable challenge, to communicate with the little ones and watch their neurons light up as they learned to create one with beads & string,” said Eric Pollard, current MSSE student.

The NTID PLAY Lab, directed by NTID faculty member Dr. Rain Bosworth, has several ongoing research projects for parents and their children on the topics of play, exploration, vision and language.  To learn more about our studies, contact our lab here: Learn more about the affiliated Sensory, Perceptual, and Cognitive Ecology (SPaCE) Center here:

The PLAY Lab is a critical resource in building a better understanding of how early sensory experiences shape our children’s visual, cognitive, and language abilities later in life. A major portion of our research focuses on the development and support of Deaf/Hard-of-Hearing children. While we are fortunate to have received support for our research, there is an ongoing need for general operating support of the Lab. Funding to maintain equipment, employ research assistants, support travel to conferences, and more, is critical in facilitating our work and in disseminating all that we will learn. If you are interested in supporting the PLAY Lab, please contact Bryan Hensel, NTID Office of External Affairs, at or at (585) 475-6222. Thank you for your generosity.
