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 DASH diet for blood pressure control

Wayne Campbell, professor in the Department of Nutrition Science, and his research team are recruiting overweight men and women ages 40 to 75 with diagnosed hypertension (high blood pressure) to participate in a research study.

Making healthy food choices, such as those in the DASH (Dietary Approaches to Stop Hypertension) diet, has been shown to improve blood pressure control in people with high blood pressure. The purpose of this study is to determine if the source of dietary protein (pork or chicken/fish) as part of the DASH diet affects blood pressure control in adults with high blood pressure.

Participants will be counseled to eat a DASH diet with pork as the major protein source for six weeks and then to eat a DASH diet with chicken and fish as the major protein sources for an additional six weeks. The study involves 12 visits to the Purdue Clinical Research Laboratory spread over an 18-week period.

Participants will be given a $400 stipend at the completion of the study.

Overweight men and women ages 40 to 75 with high blood pressure who are interested in participating in this study are encouraged to contact Drew Sayer at sayer@purdue.edu or 49-48313 for additional information.

Study on how pitch is processed in the auditory system

Native speakers of Mandarin from mainland China with normal hearing are needed for an experimental study to evaluate how sounds are processed in the human brain.

Subjects will participate in two 2.5-hour research sessions. 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. 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.

The subject's task is to lie back and relax on a recliner situated in a sound-treated booth and watch a muted video. There will be about 40 subjects in the study. Participants will receive a free hearing test.

Participants must:

* Be 20-35 years old.

* Be right-handed.

* Have no previous history of brain injury or psychiatric problems.

* Have normal hearing sensitivity by self-report.

* Be a native speaker of Mandarin from mainland China.

* Have received formal instruction in English no earlier than the age of 11.

* Have no more than three years of music training on any combination of instruments.

Subjects will be compensated $20 per two-hour session. All research will be performed in the Auditory Electrophysiology Laboratory, Heavilon Hall, Room B15. Payment will be made in the form of a check from Purdue University. Participation in the study is voluntary. Participants who withdraw from the study prior to completion will receive partial payment as judged to be fair compensation by the principal investigator, Ravi Krishnan, professor of audiology speech.
