Study Description
This study is being done to see if presenting a signal through a vibrating disk on the back of the wrist helps to better understand sentences processed using a cochlear implant simulation. We will check your hearing and then you will be asked to listen to sentences over headphones or over a speaker at a comfortable listening level, and to repeat what you heard. While listening to some of the sentences, you will wear a vibrating disk on your wrist or hand, that vibrates in a similar way to a smart watch. The session will be audio-video recorded while you do this activity, to help with scoring.
Participants will receive $15 cash or one unit of extra credit for participating, as well as a parking voucher if needed.
Participant Requirements
Listeners between the ages of 18 and 30, with normal hearing, who learned English as a first language.
Estimated Duration of Experiment
This study will take one hour.

Sentence Comprehension after Concussion

Investigators
Zoe Xu and Dr. Lori Altmann
IRB Numbers
IRB201901848
Study Description
After a head injury or concussion, people often experience memory, attention and learning problems. How does a head injury or concussion affect language comprehension and cognitive abilities? We don’t really know! Our study investigates understanding of complex language like what you would hear in a classroom.
Your participation will help us design treatment plans for people who have had concussions, and help us make decisions on when they can return to school or work.
In this online study, you will be asked to verify whether a picture matches the sentence you hear and determine which picture matches the sentence you hear. You will also perform a simple set of cognitive tests of vocabulary, memory, speed, and other aspects of cognition. The online study lasts about 1.5 – 2 hours, and you may receive 2 hours of course credit.
Participant Requirements
To participate in this study, you must be between the age of 18-35 and have no history of reading or learning disorders. You must also have spoken English since age 5 or before. Both right and left handed people are welcome in this study. We need both people with a concussion within the last year and control subjects who have no history of head injury or concussion. If you have had a concussion within the last 12 months, you either must have documentation of the injury (e.g., from MyChart) to participate in the study.

This experiment will take 1.5 ~ 2 hours

IRB Numbers
20202313
Study Description
Did you ever notice how sometimes your mood seems to affect how easy or difficult something feels?
Surprisingly, we know very little about how mood affects writing or reading comprehension. This study addresses this problem and examines the relationship between both writing and reading comprehension and mood, while taking into account individual differences in cognitive abilities. The online study takes about two hours to complete.
Participant Requirements
To do this study, you must be between age 18 and 35, and you must have learned English before you turned 7. You are not eligible for this study if you have a reading or learning disability or if you have been diagnosed with a mood or anxiety disorder.
Estimated Duration of Experiment
This study takes 2 hours.

Study Title
Mechanisms of speech motor sequence learning

IRB202000088
Study Description
Speaking seems natural and effortless. However, anyone who has ever attempted to speak in a foreign language can readily attest that the ability to produce non-native speech sequences in a fluent, coordinated, and natural-sounding way is a far from trivial skill. In addition, the challenges that clinicians encounter in treating patients with neurological disorders that affect speech production also hint at the complexity involved. The purpose of this project is to investigate how neurotypical people with healthy motor function learn to articulate novel sequences of speech sounds.
In each of the test sessions, you be asked to produce speech. Specifically, you will produce some made-up non-words comprised of sequences of consonants that do not occur in American English but do occur in some other language. We will record your voice with a microphone.
Following one of the test sessions you will be asked to wear a wrist-worn sleep monitoring device. You will be asked to wear the device overnight while you sleep. This will measure the duration and quality of your sleep based on heart rate and movement tracking measures.
Participant Requirements
All participants must be native, monolingual speakers of American English with no history of a speech, language, hearing, or other neurological deficit.
Estimated Duration of Experiment
Participation in this study will be over a total of two or three sessions, each of which will take no more than an hour including breaks.

Your descriptions of the objects will be recorded. In addition to the description task, you will be asked to complete a language history questionnaire and complete two language proficiency tasks.
There will be no monetary compensation but your participation can count for up to 2 hours in course credit.
