IRB201701843
Study Description
This study consists of two sessions, and you will need to come in on two separate days.
In the first session, you will be asked to complete some questionnaires about language and handedness. You will also be asked to do some brief tasks involving language proficiency.

In the second session, you will be reading sentences while your brain waves are recorded. You will be asked to answer comprehension questions about some of these sentences. While you are reading, there will be somebody sitting next to you. In addition to the reading task, you will also do an interactive task with the person sitting next to you.

The first session will be approximately 1 hour, and the second session will be about 1.5 to 2 hours. You will receive up to 2 hours in course credits, and will be paid for the remaining time at a rate of $10/hour.

Participant Requirements
Spanish-English bilingual college students. To qualify, you must have learned both English and Spanish before the age of 12. You need to be 18-35 years old, and right-handed. You should be neurologically healthy (no epilepsy and not taking any drugs that may affect the brain), and should have no history of dyslexia, or other hearing or language-related problems.

You will primarily be watching a series of short conversation videos on a computer screen. You will also complete a short survey that assess your English and Portuguese proficiency (if a bilingual speaker). The study lasts approximately 1 hour and you may receive up to 1 hour of course credit if applicable.
Participant Requirements
Bilingual participants are required to have Brazilian Portuguese as a native language and English as a second language, whether learned from birth/early childhood or later.

Study Description
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 30 monolingual college-age students. To qualify as a monolingual speaker English must be your native language and your knowledge of a second language should be limited (up to high school/college requirements). 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. The study lasts 1 hour 30 minutes and you may receive up to 2 hours of course credit if applicable.

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

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.

Understanding Passives in Relative Clauses

Researchers
Zoe Xu and Dr. Altmann
UF-IRB #
I2015-U-1215
Study Description
Some sentences are unexpectedly hard to understand, while others with a similar structure are much easier. Theories differ as to what makes a sentence easy or hard to understand: Is it the order in which the sentence elements (subject and verb, agent and theme) are encountered? Is it the complexity of the sentence structure? Or is it individual differences in cognitive abilities that play the largest role? This study aims to try to disentangle this issue. In this study you will be asked to determine which picture matches a written sentence. You will be asked to place your head in a padded head-rest, while your eye-movements are recorded. You will also perform a simple set of cognitive tests of vocabulary, memory, cognitive speed, and executive function.
Participant Requirements
To participate, you must be between the ages of 18-35 and have no history of brain impairment or reading disorder. You must also have spoken English since age 6 or before. Both right and left handed people are welcome in this study.
Duration of Experiment

After being walked through and having signed the Informed Consent Form (attached), research participants will be asked to complete a brief survey asking about their age, country of origin, and the like (see attached “Participant Information” form). Then they will be asked to read out loud pairs of source words presented to them on a printed research form, to then form a blend of these word pairs, and (i) say the blend out loud and (ii) write down the blend on the form (a sample Research Form is attached). The total number of word pairs presented to each participant is 30. The word pair stimuli are interspersed with distractor items that are basic math problems, like additions, subtraction, or fractions. We expect participants to complete the Informed Consent, Survey, and Research Forms in about 45 minutes.
