Researchers in various studies looking for participants

September 25, 2014  

Here is a list of research studies that currently are looking for participants.

Study about the effects of leg heating on circulation

Participants are needed for a study that will look at the acute effects of leg heating on circulation.

The experiments will take place at Lambert Fieldhouse, Room 8. Participants will be asked to come to the laboratory on two different days, separated by at least 48 hours. Blood samples will be taken before and after exposure to leg heating or a control condition. A water-circulating garment connected to a water pump will be used for leg heating. Each test day will last about five hours.

Participants will receive $50 for completing the study.

Men and women ages 18 to 35 who are healthy, are nonsmokers, do not participate in any kind of supervised physical activity or exercise for more than four days a week, and are interested in participating in this study should contact Bruno Roseguini at


Study on language and motor learning in children with childhood apraxia of speech

Children ages 4-8 with childhood apraxia of speech are needed to participate in a study on language and motor learning conducted by Lisa Goffman, professor in the Department of Speech, Language, and Hearing Sciences. 

Children must be native speakers of English to participate.

Children will be asked to attend five to six sessions, each lasting approximately one hour. Children will receive a toy and parents will be paid $10 for each session. Children also will receive a free assessment of their speech, language, motor and hearing abilities.

Testing multisensory feedback system for image perception

Blind and sighted men and women over 18 years of age are needed to test a multisensory feedback system for image perception.

Currently there is no suitable technology for blind or visually impaired (BVI) persons to acquire scientific skills such as operating microscopes and navigating histology images. These skills are crucial during STEM education. We propose a real-time multimodal image perception system to enable BVI participants to engage in typical biomedical lab activities: a combination of auditory, haptic, and tactile feedbacks are deployed to convey visual information in suitable perceptual channels, thus creating a palette of multimodal, sensorial information.

Participants will use a stylus haptic device to navigate the images shown on a computer screen. The feedbacks are provided through computer speaker, a vibration device attached to cloth, and the haptic device. As a comparison, participants also will be asked to explore tactile images produced on paper and by a 3-D printer. The experiment will last approximately 30 minutes and will take place in Mann Hall, Room B035A.

Study on personality, romantic relationship satisfaction and couple interactions

Cohabitating and/or married couples who have been in a relationship for at least one year are needed for a study examining the associations between personality, romantic relationship satisfaction, and couple interactions.

Participants must be age 18-35. The study will include answering questionnaires online and in the lab as well as participating in tasks with your romantic partner.

Participants will be paid $15 for completion of study ($30 per couple). For more information, email


Study about effects of interaction with smartphone and social networking on human perception

Men and women age 18 to 30 are needed for a study to find the influence of interacting with electrical devices on hormone changes, emotions and attitude.

Participants must be smartphone users and Facebook users logging on both smartphones and desktop computer at least twice a day on average.

Participants will do a simple task (searching information or social networking) with an electrical device (smartphone or computer) for five minutes. Participants will be required to finish a 15- to 20-minute survey before and after the experiment. To detect hormone changes, saliva samples will be collected before and after the task. Participation will take no more than 50 minutes.

Those who take part in the study will be compensated with either credit by an instructor or $15.

To participate or for more information, contact Christopher Kowal, assistant professor of consumer sciences, at 49-49234 or


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 an online survey about 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 30- to 40-minute survey. Participants who meet the eligibility criteria will be compensated for their time with a $4 Starbucks gift card. Participation is voluntary and confidential.

Study investigating the use of a Wii Balance Board to measure balance ability in infants

Infants from 7 to 8 months of age who are independently sitting are needed for a study investigating the validity of the Wii Balance Board for measuring balance abilities in infants. 

Research has shown that the Wii Balance Board is a valid and reliable method for measuring balance abilities in children and adults. However, it is unknown if the same can be said for infants as they are significantly smaller and weigh less than children and adults. 

Researchers will measure infants' balance while they are sitting on both a Wii Balance Board and on a force plate (the standard way to measure balance in infants) in order to assess whether or not the Wii Balance Board is as accurate as the force plate. If the Wii Balance Board is a valid measure of balance in infants, it has the potential to be used in the future to help clinicians diagnose infants with motor problems due to its affordability and portability.

The project consists of one 30-minute session at the Life-Span Motor Development Lab in Lambert Fieldhouse. Infants must be capable of sitting independently (without any support) for a brief period of time. Participants will receive an infant-sized T-shirt for participating.

To participate or for more information, contact Laura Claxton, associate professor of health and kinesiology, at 49-62293 or


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.

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, or call 49-44445 and leave your contact information.


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.

For more information, contact Stephanie Rose at 937-532-4914 or


Study on 4- and 5-year-olds who stutter

Children who stutter (repeat sounds and syllables) and who are 4 or 5 years old are needed for a study examining persistence and recovery from stuttering. Children must speak English and have normal hearing and cognitive skills.

Families will receive a free assessment of their child's speech, language and hearing abilities, plus a written report. Participants will attend five 90-minute testing sessions, and the child will receive a toy after each session. 

Families of eligible children will receive $100 in compensation at the conclusion of the testing sessions ($200 if they live more than 60 miles from Purdue).

Principal investigators are Anne Smith and Christine Weber-Fox, professors in the Department of Speech, Language, and Hearing Sciences. For more information, contact Barbara Brown at or 49-66403.


Study on the impact of drinking common beverages with breakfast on blood glucose and insulin levels

Participants with or without Type 2 diabetes are being sought to participate in a study that will look at how drinking different common beverages (milk, low-fat milk, nonfat milk, orange juice, coffee and water) with a meal changes blood sugar and insulin levels after eating.

Participants will come to Purdue Clinical Research Center on six mornings separated by at least one week. On each of the mornings, participants will consume a breakfast with one cup of a beverage. Blood samples will be taken before and every 30 minutes after eating for four hours to test blood sugar and insulin levels from an IV line. Each test day will last about five hours.

Measurements include calories and nutrients in the participant's diet, weight/height/lean tissue, and blood glucose and insulin levels. Participants will receive $500 for completing the study.

Men and women ages 35 to 65 who are overweight, nonsmoking, not pregnant and interested in participating in this study should contact Jia Li at or 49-41706 for more information.

The principal investigator is Wayne Campbell, professor in the Department of Nutrition Science.
