Study on autonomous vehicle use and acceptance

Individuals are needed for a study focused on investigating the effect of introductory materials on autonomous vehicle use, secondary task performance, and AV trust and acceptance. Through this study, researchers hope to better understand how engagement with secondary tasks while being autonomously driven affects trust and acceptance of AV.

Participants will complete an online survey that includes questions on socioeconomic information and attitudes toward different types of automation. Those over age 65 also will need to complete an additional, short over-the-phone pre-screen for memory impairment. Participants also will come to the NEXTRANS Center in Purdue Research Park to complete an experiment in a driving simulator (estimated 2.5-hour duration).

Potential participants must be licensed drivers who are at least 18 years old, not prone to motion sickness, and without mental impairment or physical impairment that would make it difficult for them to get in and out of the driver’s seat of the simulator unassisted. Participants are asked that no medications, caffeine or nicotine be consumed eight hours before the time of participation.

Participants will not receive compensation for completing only the online survey. Full completion of the 2.5-hour study will be compensated between $15 and $45, and partial completion of the study will be compensated $15.

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 or 765-494-0408.

The principal investigator is Ulrike Dydak, associate professor in the School of Health Sciences. IRB#: 1102010525.
