Study investigating walking stability when infants and toddlers carry toys
Newly walking infants and toddlers are needed for a study investigating walking stability. Research has shown that infants holding toys in a standing task show an increase in standing stability. Researchers are interested in whether the same is true when infants/toddlers are walking while carrying toys.
Infants and toddlers will engage in a 20-minute free-play session with toys of different sizes and weights and then will be encouraged to walk down a straight pathway carrying toys of different sizes and weights. To measure walking characteristics (e.g., walking speed, step length, step width), children will wear reflective markers on their ankles, so that researchers can capture their movements using specialized motion capture cameras.
The project consists of a 40- to 45-minute session at the Life-Span Motor Development Lab in Lambert Hall. Newly walking infants (ages 13 months to 14 months) must be capable of walking independently (without any support) for at least 10 consecutive steps. Researchers are also recruiting toddlers (23.5 to 24.5 months). Children will receive a Motor Development Lab T-shirt, and parents will receive $5 for travel costs.
To participate or for more information, contact Laura Claxton, associate professor of health and kinesiology, at 765-496-2293 or firstname.lastname@example.org. IRB#: 1608018080.
Research project investigating the relationship between cognitive and motor abilities in 2-year-olds
Children ages 2 years to 2 years and 11 months are needed for a project exploring the relationship between cognitive and motor abilities in children.
Many developmental disorders (e.g., autism, ADHD, developmental coordination disorder) are characterized by problems in both cognitive skills (e.g., problem-solving, working memory) and motor skills function (e.g., balancing, running). Researchers are investigating possible common central mechanisms involved in these two domains in typically developing children. The researchers hope that the findings from this research will lead to the development of intervention techniques such as motor skills training that will have the potential to improve cognitive skills in both special needs populations and typically developing children.
The parent and child will visit the Life-Span Motor Development Lab at Purdue for a 1-hour-and-15-minute session. The child will be asked to complete a few cognitive games (using memory and problem-solving skills) and a few motor skills games (using fine motor skills and balance abilities). For example, for one of the cognitive games, the child will be asked to sort objects based on their size. For one of the motor games, the child will be asked to build a tower out of blocks, and for another, the child will stand on a device that measures balance abilities. In addition, parents will complete two questionnaires during the test session. The child will receive a small gift as a token appreciation, and parents will receive $5 for completing the questionnaires.
To participate or for more information, contact Laura Claxton, associate professor of health and kinesiology, at 765-496-2293 or email@example.com. IRB#: 1703018889.
Maternal Context of Pregnancy Project
Women in the first trimester of pregnancy are needed for the Maternal Context of Pregnancy Project, which examines the relationships between experiences mothers may have during pregnancy and how those experiences might “get under the skin” and affect children’s development.
Participation includes one online questionnaire and hair sample (to assess levels of hormones related to stress and pregnancy) once per trimester (at about 12, 26 and 38 weeks pregnant), and an online questionnaire and cheek swabs from mother and baby at six months postpartum. Around the time of delivery, with the help of participants’ hospital, birth center or midwife, a small sample of blood from the mother and some samples of the placenta will be collected to examine changes in gene expression related to different kinds of experiences during pregnancy.
Participants are compensated $25 per assessment (a total of $100 for the whole study) as appreciation for their time.
Sodium and fat quantification by MRI
This study aims to test and optimize a novel noninvasive method to quantify muscle sodium concentration and fat content by using magnetic resonance imaging (MRI). Sodium and fat levels in skeletal muscle can be used as a marker of several common diseases. Researchers aim to develop a method to quantify these levels accurately and noninvasively. Since sodium and fat levels are age-related, volunteers covering a wide range of age are needed for this development.
The researchers are looking for healthy boys and girls age 10-17. The researcher will take several MRI images of the left calf of the participant. Participants will be asked to come for one MRI exam, which takes about one hour. After the participants finish the one-time participation, they will receive $20 and their MRI images.
Those interested in participating or who would like more information should contact Ahmad Alhulail at firstname.lastname@example.org or 765-494-0408.
The principal investigator is Ulrike Dydak, associate professor in the School of Health Sciences. IRB#: 1102010525.
Swallowing and speech study for children with cerebral palsy
