IRB Numbers
201901605
Study Description
The purpose of this research study is to investigate how the brain processes language, specifically in English-speaking monolinguals. In order to track brain activity we will use electroencephalography (EEG), a non-invasive neuroimaging technique that enables to measure the spontaneous electrical brain activity produced by the brain.

During the study, you will be asked to complete a number of short tasks (i.e., 1) a language history questionnaire, 2) a handedness questionnaire, 3) a short memory task (operational span (O-Span), and 4) the main parts of the study which will include a “resting state EEG sequence” and a sentence comprehension task while EEG will be recorded. During the sentence comprehension task, you will be silently reading sentences word-by-word on a computer screen while your brain waves are recorded. Some sentences will be followed by a question that you can answer by pressing buttons on the gamepad. In this task, your brain waves and the responses you give on the game pad will be recorded.

You will be compensated up to 2 hours in course credits.

Participant Requirements
Age: between 18-35 years old. Language: Monolingual speakers of English. Handedness: Right-Handed.
Estimated Duration of Experiment
Approximately 2.0 hours
Number of Subjects Needed

Study Description
We are looking for native English speakers to participate in a linguistic study on the relationship between the spelling and reading. The experiment compares word recognition and text comprehension in English and Spanish by native speakers of each language respectively. You will first see 96 letter strings, and you must decide if they are real words or not. You will then read a passage containing about 500 words and fill in each of 20 blanks with a word that fits in the text. To participate, you must be between the ages of 18 and 75, with normal or corrected-to-normal vision and no history of speech/language disorders or cognitive decline. English must also be your sole native language. If you are fluent in any other language, that fluency must have been achieved by formal practice and/or post-childhood immersion, not by natural upbringing. This experiment will take approximately one hour at the most.
Participant Requirements
native monolingual English speakers with normal or corrected-to-normal vision

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.

This study will take 2 hours.
