The purpose of this research study is to investigate how human interpret some predictive learned by AI systems when detecting deceptive hotel reviews and how AI explanations can shape human understanding. For instance, the AI system learns that words like "floor" and "bathroom" are highly predictive of genuine reviews and words like "husband" and "luxury" are highly predictive of deceptive reviews. While the AI system highlights these words by learning from the data, the association between these words and the outcome are not easy to comprehend for humans. Thus, our goal of this research is to investigate how participants interact with machine-generated explanations that are unintuitive, and how participants make use of our developed visualizations and tools to make sense of these unintuitive features.

The UNC MOTION Science Institute is seeking volunteers with a history of anterior cruciate ligament (ACL) reconstruction surgery and healthy controls for a research study on the effects of stroboscopic vision on walking gait biomechanics, and how the somatosensory function may influence these changes. Individuals who have injured their ACLs are at a high risk of developing post-traumatic osteoarthritis, in part due to altered gait biomechanics. Stroboscopic vision has been shown to alter biomechanics in other tasks and populations, but its effects on walking biomechanics following ACL reconstruction is unknown.

The purpose of this study is to find out whether the current method of calculating stomach volume using ultrasound is accurate in patients who have had a previous gastric sleeve procedure.

The goal of this study is to gather more information on the experiences of LGBTQ+ individuals during the family planning process, specifically as they relate to elements of stress and social support. This study will include any LGBTQ+ individuals who have gone through any part of the family planning process, as well as people who work with LGBTQ+ individuals, including (but not limited to) doctors, doulas, lactation consultants, and legal professionals. This will provide groundwork to guide questions in future research on parent and child health in LGBTQ+ populations.

In this study, I want to learn how people who identify as Latino, Hispanic, and/or from Latin America make sense of and understand their identity.
