UF-IRB #
IRB201601896
Study Description
Bilingual Spanish-English speakers between the ages of 18-40 years, with normal hearing, and no history of speech or hearing disorders are invited to participate in a study of speech perception. You will be seated at a computer in a quiet room while hearing speech sounds over headphones. You will be asked to label the sounds based on what you hear. You will also be asked to read sentences out loud in English or Spanish into a microphone. Our primary goal is to examine how bilinguals make use of speech cues in different language “modes”.
Participant Requirements
Participants must be Spanish/English bilinguals (having acquired both languages before age 8 yrs)

IRB201700253
Study Description
You will hear three stimuli per trial and your job is to determine if you think the last stimulus is similar to the first (A) or the second (B) stimulus by clicking a button A or B on the computer screen. 144 experimental trials will be presented preceded by 10 practice trials to familiarize you with the procedure.

For native speakers of Chinese, you will also be asked to perform a second task. In this task, you will hear one stimulus at a time, and your job is to determine if you think its pitch is similar to tone 1, 2, 3, or 4 of Mandarin Chinese but selecting the corresponding number on the computer screen. A total of 61 trials will be presented.

Participant Requirements
You must be a native speaker of English or Mandarin Chinese

Researchers
Dr. Kenneth Logan, Caley Carbaugh
UF-IRB #
IRB201601906, Approved
Study Description
The purpose of this study is to identify factors that contribute to adults’ ability to identify stuttered speech accurately and efficiently. You will be asked to complete a questionnaire upon which you will provide background information about yourself, such as age, gender, education level, and experience with assessing or evaluating speech fluency. You then will listen to a series of audio-recorded sentences. You will be provided with a rating scale, which you will use to rate the fluency of each sentence.

While we do not offer any compensation for participating, many professors within this college offer extra credit for participating in research studies.

Participant Requirements
To participate, you must be at least 18 years of age, with no significant hearing or vision problems, and no prior experience in evaluating stuttered speech.
Duration of Experiment
This experiment will take approximately 45 minutes to 1 hour.

Ideas and Executive Function


Date Study Posted

Researchers
Lori Altmann
UF-IRB #
2016-01439
Study Description
To begin speaking, you need to have an idea to convey. Is that idea already in linguistic form or is it in some other form? Most theories assume there is a “nonlinguistic” level of thinking that precedes linguistic encoding. Evidence from adults with cognitive impairments indicates that impaired cognition is often accompanied by lower numbers of ideas in discourse, leading to “empty speech.” This suggests that idea generation may have a cognitive component.

This study will be one of the first studies examining the relationship between idea generation and cognition. As part of this study you will do 5 tasks asking you generate language of different kinds (words, phrases, sentences, discourse). You will also complete a vocabulary test, and various memory and executive function tests. The experiment should take about 2 hours.

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.

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.
Email Jorge at jvaldeskroff@ufl.edu with the subject line “Cognitive Control” if you are
interested in participating or if you have further questions!
Participant Requirements
Functionally English monolingual speakers or Spanish-English bilingual speakers

Study Description
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.
