Study on how brain combines sight and sound

Children ages 8-10 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 8-10 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.

 

Study on effects of a single bout of exercise on cardiovascular risk factors

Tara Henagan and Humaira Gowher, assistant professors in the departments of Nutrition Science and Biochemistry, respectively, are conducting a research study that will look at how a single bout of cycling exercise will influence changes in skeletal muscle and health during overweight and obesity.

For this study, participants will come to the Purdue Clinical Research Center for testing. Depending on the scheduling needs of participants, the study will consist of one to three days of testing. Testing will include measures of body composition (including percent body fat and lean mass muscle mass), clinical health parameters (i.e., blood pressure, heart rate, total, HDL and LDL cholesterol, glucose and insulin levels, lipid and epigenetic markers in muscle), filling out questionnaires related to health and physical activity, VO2max or cardiovascular fitness testing and one bout of cycling exercise lasting approximately one to two hours.

Participants will receive $200 for completing the study.

Men age 18 to 30 who are in general good health, are nonsmokers and have had a physical examination by a state-licensed M.D. or D.O. in the past two years or are willing to have a physical examination performed by a state-licensed M.D. or D.O. are eligible to participate. For more information, contact Prasad Devarshi at pdevarsh@purdue.edu or 765-586-3952.

 

Early autism identification infant-sibling study

The Purdue University Developmental Studies Laboratory is conducting a study of developmental trajectories in infants at risk for autism spectrum disorders (ASD).

Laboratory visits include several play-based tasks at 12, 15, 18, 24 and 30 months of age. After each visit, families receive $50 compensation and a report detailing their child's developmental progress, including information on his/her language, motor and social skills.

To be eligible, infant siblings must be between 12 and 19 months of age and have an older sibling who currently has an ASD diagnosis or an older sibling who is typically developing. This research aims to assist early identification and treatment for children with ASD.

All inquiries should be directed to the Developmental Studies Laboratory at 49-46610 or ajlab@purdue.edu. More information is at purdue.edu/hhs/hdfs/dslab.

 

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, right-handed, have no history of brain injury or psychiatric problems, and 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.

 

Study on effects of daily timing of protein intake

This study will look at how within-day patterning of protein intake (even vs. skewed) combined with resistance training will influence changes in body composition, skeletal muscle and health during weight loss.

For this 18-week study, participants will come to the Purdue Clinical Research Center for eight testing days, which are before (baseline) and at the end of a 16-week weight loss intervention consisting of a controlled diet and resistance training program. Dietary counseling, gym memberships and personal trainers will be provided. Testing days will include measures of body composition (including muscle size), muscle strength and fitness, and clinical health parameters (i.e., blood pressure).

Participants will receive $1,000 for completing the study.

Men and women age 19 to 50 who are overweight, in general good health, nonsmokers, nonpregnant, and interested in participating in this study should contact Jan Green at jkgreen@purdue.edu or 49-47660 for more information.

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