Researchers in various studies looking for participants
August 14, 2014
Here is a list of research studies that currently are looking for participants.
Study to evaluate how sounds are processed in the human brain
English- and Chinese-speaking adults with normal hearing are needed for an experimental study to evaluate how sounds are processed in the human brain.
Subjects will participate in a minimum of two 2-hour research sessions. Subjects will be asked to fill out forms before the actual experiment. The experimental procedure consists of recording electrical activity from the brain (using EEG-type electrodes attached to the head) in response to various sounds presented through headphones at comfortable listening levels. The subject's task is to lie back and relax on a recliner situated in a sound-treated booth.
There will be about 40 subjects in the study. All research will be performed in the Auditory Electrophysiology Laboratory, Lyles-Porter Hall, Room 3043.
Participation in the study is voluntary. Participants who withdraw from the study before completion will receive compensation pro-rated based on amount of time completed. Payment will be given to subjects in the form of cash at the end of each session.
All subjects must be ages 20-35, right-handed, have no history of brain injury or psychiatric problems, and have normal hearing sensitivity by self-report.
Chinese subjects must be native speakers of Mandarin from mainland China, have received formal instruction in English no earlier than age 9, and have no more than three years of music training on any combination of instruments.
English-speaking subjects must be native English speakers from the United States, must have no familiarity with spoken Chinese or any other tone language and have no more than three years of music training on any combination of instruments.

Purdue Libraries seeking participants for user testing
Purdue University Libraries is conducting user evaluation for the library website (www.lib.purdue.edu). In the evaluation, participants will be asked to complete a set of testing tasks with the website and provide feedback. The evaluation is expected to take up to one hour. Participants will receive $10 if they complete the evaluation.
Participants must be currently enrolled students, staff or faculty at Purdue and have experience with using Purdue University Libraries website or other academic search websites.
Contact Tao Zhang at firstname.lastname@example.org to schedule an evaluation time.
Study on how brain combines sight and sound
Children ages 7-11 are needed for a study on how the brain combines sight and sound.
Natalya Kaganovich, assistant professor of speech, language, and hearing sciences and psychological sciences, is studying how the brain’s ability to combine auditory and visual information develops in childhood and how it may be impaired in speech/language disorders.
Children will participate in five research sessions, 1.5 to 3 hours each. Participants will first take a series of standardized tests that will evaluate working memory, nonverbal intelligence, and language skills.
Children will then participate in two brain-wave recordings during which their brain activity to audiovisual speech will be collected. Brain-wave recording sessions are structured as games. Brain waves will be collected with the help of a special cap with built-in electrodes (similar to EEG recordings). There is no discomfort involved, and the method has been safely used with infants, children and adults.
To participate, children must be 7-11 years old; typically developing; right-handed native speakers of American English; and free of speech, language, hearing/vision or neurological disorders and conditions such as autism/Asperger’s, head injuries, seizures, brain tumors, cerebral palsy, ADHD, stuttering and depression; and should not be currently on medications that may affect brain activity (e.g., medications to control ADHD, seizures or depression).
Children will be compensated $10 per hour and will receive a small toy (worth approximately $5) at the end of each session. Parents also will be paid $10 per session.
To participate, contact Jennifer Schumaker at email@example.com, or call 49-44445 and leave your contact information.
Study on being marginalized by family
Adults ages 25-35 who have at least one sibling and who feel like the "black sheep" of their family are needed for a study on family relationships.
In some societies, marginalized family members are called "black sheep" because they stand out from the rest of the group. Being marginalized refers to feeling different, not included, or not approved of by family. Everyone feels marginalized by family at one time or another, but participants must have been made to feel this way by multiple family members from their family of origin (the family they grew up with) and have felt this way for at least one year at any point during the past 10 years.
Participants will complete a short survey and a 45- to 60-minute in-person or Skype interview. Participants will be compensated for their time with a $10 gift card. Participation is voluntary and confidential.
For more information or to sign up to participate, contact Elizabeth Dorrance Hall in the Brian Lamb School of Communication at firstname.lastname@example.org or 269-370-7454.
Study about relationships between verbs and grammar in children with cochlear implants
Researchers are conducting a study to determine language skills and development of children ages 27-30 months, and parents of children with normal hearing are invited to participate.
Each parent and child will participate in a single 60- to 90-minute session. It will include 20 minutes of playtime between parent and child. Parents will then answer a questionnaire about words their children can say, and they will be interviewed about their child's development. Children will receive a free hearing screening during the session.
Parents will receive $20, and each child will receive a small toy or gift certificate for participation.
Those interested should contact Jongmin Jung at email@example.com or 49-62250.
Study on walking behaviors
Researchers at Purdue are conducting a study of walking behaviors.
At baseline, six months and 12 months, researchers will ask participants to complete three online surveys. The surveys will take 10-15 minutes to complete, and participants will be asked to complete the surveys within one week of receiving them.
Adults who do not regularly walk for exercise or physical activity, but who speak English, have regular use of email and can tolerate 30 minutes of walking, are eligible to participate.
The study begins in September. For more information, contact Libby Richards at firstname.lastname@example.org.
Study about men's experiences after miscarriage
Men whose partners have suffered a miscarriage are invited to share their experiences with researchers in a private interview.
The interviews will take place at Purdue and will last 60-90 minutes. The study is intended to increase public awareness of men's experiences after miscarriage, give men a voice in such research and aid health care and mental health professionals in providing effective services to men.
Participants can choose to receive a $10 gift card or donate that amount to March of Dimes.

Dog owner heart health promotion study
Researchers are conducting a 12-month study of the health benefits of dog ownership.
Adult dog owners who do not regularly walk their dog, but who speak English, have regular use of email, and own a non-aggressive dog at least 6 months old whose height is at least 14 inches, are eligible to participate. Owners and dogs should be able to tolerate 30 minutes of walking.
At baseline and 12 months, participants will be asked to schedule a 30-minute visit on campus with their dog. During these two visits, a small urine sample will be collected from the dogs. Also at these visits, the dog owner will receive a free health screening including basic labs; blood will be obtained from a small finger stick. Participants will need to fast for eight hours before these labs. Participants also will complete three online surveys. The study will start in September.
Participants will receive $35 for each visit plus $10 for completing questionnaires.
