UF-IRB #
201801695
Study Description
No clinical audiology tests of speech perception evaluate the integration of hearing between two ears in a room. Hearing in a room with two ears benefits speech perception in noise, but it is difficult to evaluate because it requires multiple loudspeakers and sound booths are different sizes, altering acoustics. This project examines whether speech perception in noise differs across sound booth of different sizes and if altering the acoustics of the testing can result in equivalent results. As part of this study you will have your hearing screened. You will also listen to speech in background noise and repeat what you hear and will hear sounds and be asked to choose which sound was different. The total participation time for this study is between one and two hours.
Participant Requirements
To participate, you must be between the ages of 18-60 and have normal hearing. You must also be a native speaker of American English (learned English at home before entering elementary school) and have no history of speech or language disorders or cognitive decline.
Duration of Experiment
This experiment will take 1-2 hours

Study Description
How do we learn language? Amazingly, children pick up the patterns in language with no explicit instruction. This study investigates a number of different ways people learn which may contribute to language acquisition. You will complete tasks that assess language, working memory, and speed of processing. The purpose of this study is to develop a clearer understanding of how different types of learning contribute to language use. What we learn from this study will then be used to better assess and treat children and adults with language impairments.
Participant Requirements
You must be 18-35 years old, with no history of language impairment, reading impairment, or brain injury.
Duration of Experiment
This study will take 2 hours.

Measuring Maximum Tongue Protrusion Force (MTPF) in healthy normal adults


Date Study Posted

Researchers
Jayoung Kim & Paul Davenport
UF-IRB #
IRB201700324
Study Description
We assumed that increased tongue strength may have a potential to improve normal breathing. Because genioglossus tongue muscle plays an important role in tongue protrusion, stiffens the tongue, and prevents posterior tongue displacement and upper airway closure such as sleep apnea. We believe that tongue protrusion can be trained to increase protrusion strength by active forward protrusion exercise.

Study Description
Does speaking more than one language provide benefits that go beyond language
comprehension and speaking? Participate in this study to help us learn more!
Researchers in the Departments of Spanish and Portuguese Studies and Psychology at UF
are studying whether the constant navigation between Spanish and English aids in better
ignoring distracting information. This study will expand what we know about
bilingualism and general cognition.We are looking for 60 monolingual and 60 Spanish-English bilingual college-age
students. To qualify as a bilingual participant you must have learned English and
Spanish simultaneously or learned Spanish first and English second. If you identify as a
person who has a language, learning, or hearing disorder, you do not qualify for this
study. You will primarily be reading a series of words on a computer screen and will be
asked to respond to the color that the word is presented in via button press. You will also
complete a few cognitive tasks and tests that assess your English and Spanish proficiency
(if a bilingual speaker). The study lasts approximately between 1 hour and 1 hour 30
minutes and you may receive up to 2 hours of course credit if applicable.
