Researchers in various studies looking for participants

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

 

Women needed for a research study on the effects of contraceptives on bone health and hormonal status

Women who exercise are needed for a research study investigating the effect of oral vs. non-oral contraceptives on the production of hormones essential for growth and the maintenance of bone health. Participants will receive measures of body composition, hormone levels and aerobic fitness, and will also be given the option to take hormonal contraceptives during the study.

Participants should be women age 18-31 who have regular menstrual cycles, i.e., at least nine menses in the past 12 months, and have not taken birth control pills or other hormonal contraceptives in the last six months.

The study requires regular visits to Department of Nutrition Science over the course of four months. Participants can choose to take a contraceptive option or not during the study. Within the contraceptive use group, participants are randomly assigned to use of an oral contraceptive pill or the vaginal ring. The principal investigator is Connie Weaver, distinguished professor in the department.

If interested in participating, call Berdine Martin at 494-6559 or Mike Stone at 494-0385, or send an email to FNbone@purdue.edu. In your phone call or email, please mention the Contraception Study. IRB#: 1410015308.

Study on how brain combines sight and sound

Twelve-year-old girls 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 four research sessions, 1.5 to 2 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 11-12 years old; typically developing native speakers of American English; 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 jschumak@purdue.edu, or call 49-44445 and leave your contact information. IRB#: 0909008484.

Study to evaluate how sounds are processed in the human brain

Chinese- and English-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 two-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. Subjects are compensated at $25/session.

All subjects must be 20-35 years old, be 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.

To participate, contact Whitney Lyle at wlyle@purdue.edu. IRB#: 0506002731.
