A payment of $20 per visit will be given to participating parents as appreciation for their time. For more information, contact Laura Anaya at firstname.lastname@example.org.
Study on how brain combines sight and sound
Children age 8-12 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 8-12 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 email@example.com, or call 49-44445 and leave your contact information.
Study on how eating eggs influences absorption of beneficial plant pigments (carotenoids) and vitamin D from vegetables
This study will look at how the presence of cooked eggs will affect beneficial plant pigments (carotenoids) and vitamin D absorption when consumed with cooked vegetables.
Participants will report to the Purdue Clinical Research Center for two days of testing, and each testing will be separated by a three-week free living, seven-day controlled diet period. Testing days will consist of consuming a test meal followed by blood collections every 60 minutes over a 10-hour period. This study will take a minimum of six weeks to complete.
Participants will receive $400 for completing the study.
Interested subjects should be pre-menopausal (regularly menstruating, age 19-45) or post-menopausal (age 60+) women who are in general good health and who do not smoke. Those interested in participating in this study should contact Jan Green at firstname.lastname@example.org or 496-6342 for more information.

Study seeking patients with Parkinson's disease, older adults
Purdue researchers are seeking adults who are 60 years or older with and without Parkinson's disease, to participate in a study that is designed to help people improve older adults' mobility.
A research team from Purdue's College of Health and Human Sciences is testing an intervention to help older adults improve balance while performing cognitively demanding tasks. The team developed COgnitive-based BALance Training (COBALT) to simultaneously train balance and cognition, by simulating the demands inherent in common tasks. The researchers are evaluating this training program, along with two other programs, to determine which will help older adults improve their walking and balance.
The study is 12 weeks long and participants will be financially compensated. For more information, contact Sandy Snyder, the study coordinator, at email@example.com.
