Researchers in various studies looking for participants
Here is a list of research studies that currently are looking for participants.
Participants needed for a speech perception study
Individuals age 60 and older who are native speakers of American English and do not wear hearing aids are needed for a study investigating speech perception in complex listening conditions. The study, "Aging and Speech Perception," is being conducted by the Cognition, Hearing and Training (CHAT) Laboratory at Purdue.
Participants will be paid $10 an hour for 1-2 sessions, each 45-90 minutes long.
The principal investigator is Alexander L. Francis, associate professor of speech, language, and hearing sciences. He may be contacted for more information at francisa@purdue.edu or 49-43815.
Study about food preferences in preschool-age children
Sibylle Kranz, associate professor of foods and nutrition, is recruiting for a research study about food appearance and taste in young children.
Children ages 2-5 are eligible to participate and will be asked to taste and rank different foods using the "smiley face game." Children will come to Purdue four times over the course of a year to taste different foods and rank how appealing the foods are with different presentations. Each visit will last approximately 30-60 minutes, and children will be given a small toy in appreciation of their participation at the end of the fourth visit. Parents will be reimbursed for mileage to and from Purdue.
This research will give new insight into taste and presentation preferences in young children.
Those interested in participating should contact Mary Brauchla at mbrauchl@purdue.edu or 49-42461.
Food preference vs. liking of food in preschool-age children
Sibylle Kranz, associate professor of foods and nutrition, is recruiting for a research study about food preferences and food liking in young children.
Children ages 2-5 with no food allergies are eligible to participate and will be asked to come to Purdue three times for visits of less than 30 minutes. Children will be asked to taste different drinks and use the "smiley face game" to say if they taste different or the same as water. These drinks will be flavored as sweet, salty, bitter and sour, and children's perception of these tastes will be tested. On the final test, children will be asked which of the four tastes they prefer.
There is no monetary compensation for this study, but results may give new insight into taste preferences and taste thresholds in young children.
Those interested in participating should contact Mary Brauchla at mbrauchl@purdue.edu or 49-42461.
Study about children's eating behaviors
Sibylle Kranz, associate professor of foods and nutrition, is conducting a study about children's eating behaviors. The study will evaluate how visual cues will affect how much food young children will consume.
Children ages 2-5 will be asked to come to Purdue on six different days. The children will be asked to stay from 9:30 a.m. until noon, and parents may stay or drop off their children if they wish. Children will have time for free play and organized activities similar to those at local day care centers. Researchers will serve a snack to the children at 10 a.m. and then serve lunch at 11:30 a.m.
Parents will be given $18 at the end of the study, and children will be given a small toy at the end of each visit. Those interested in having their child participate should contact Mary Brauchla at 49-42461 or mbrauchl@purdue.edu.
Study on how sounds are processed in the brain
Adults with mild to moderate permanent hearing loss are needed for an experimental study evaluating how sounds are processed in the human brain.
Ananthanarayan Krishnan, professor of audiology in the Department of Speech, Language, and Hearing Sciences and principal investigator, is studying how pitch is processed in the brainstem.
Adults with mild to moderate permanent hearing loss will participate in a two-hour research session, during which their brain activity will be recorded in response to different sound stimuli. 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 participants need to lie back and relax (fall asleep preferably) on a recliner situated in a sound-treated booth. There is no discomfort involved, and the method has been used safely with infants, children and adults.
All research will be performed in the Auditory Electrophysiology Laboratory, Heavilon Hall, Room B15. Payment will be given to participants in the form of a check from Purdue University. Participation in this study is completely voluntary. Participants who withdraw from the study prior to completion will receive partial payment as judged to be fair compensation by the principal investigator. Participants will be compensated $10 per hour ($20 for the two-hour session).
To participate, subjects must be 20-45 years old with normal hearing; right-handed; 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; also they should not be currently on medications that may affect brain activity (e.g., medications to control ADHD, seizures or depression).
To participate, contact Saradha Ananthakrishnan at sanantha@purdue.edu.

Children will participate in three 1.5- to 2-hour research sessions. Participants first will take a series of standardized tests that will evaluate working memory, attention, nonverbal intelligence and language skills.
They then will participate in a brain wave recording during which their brain activity in response to both speech and nonspeech audiovisual information 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 used safely with infants, children and adults.
To participate, children must be right-handed native speakers of American English; must be 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.

Study investigating balance control in newly standing infants
Newly standing infants (11 month to 13 months of age) are needed for a study investigating the mechanisms influencing balance control in infants. Researchers are interested in the different factors that contribute to infants' being able to control their balance and stand upright. Infants will be standing on a platform that measures their body sway when they stand on their own, when they hold a toy, and when they look at a video of a toy.
The project consists of one 30-minute session at the Life-Span Motor Development Lab in Lambert Fieldhouse. Infants must be capable of standing independently (without any support) for a brief period of time. Researchers are looking for infants who are using furniture and other objects to walk around in their environment, but are not yet able to walk more than a few steps on their own. Participants will receive an infant-sized T-shirt.
To express interest in participating or to receive more information, contact Laura Claxton, assistant professor of health and kinesiology, at 49-62293 or ljclaxton@purdue.edu.
Study investigating balance control in newly sitting infants
Newly sitting infants (4 months to 10 months of age) are needed for a study investigating the mechanisms influencing balance control in infants. Previous research in the Life-Span Motor Development Lab in the Department of Health and Kinesiology has found that newly standing infants are capable of surprisingly stable balance when they are engaged in an attention-demanding task. Researchers want to see if this same phenomenon is also occurring in newly sitting infants.
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.
