Current Studies
Our lab is interested in better understanding how children and college students learn about the world. Check out the descriptions below to learn about our ongoing projects!
Temperament & Early Number Learning
The development of early numeracy skills in children is vital for later academic success. However, the literature thus far has not related temperament to numeracy skills in early childhood. We are currently conducting a study looking at how temperament influences number learning in 2.5- to 5-year-old children. This project is also a part of a larger project known as ManyNumbers that aims to understand early numeracy in children all over the world!
Influences on Shared Storybook Reading
Shared storybook reading predicts developmental outcomes in language, literacy, and even math learning! Yet it is unknown what individual differences in families create strong home reading environments that best support these early skills. To address this question, this project has caregivers complete surveys about themselves and their 4-year-old children. Then, participants join a virtual call where they read storybooks together and play games that test children's story comprehension. We hope to use the results of the study to better understand what shared storybook reading looks like in the real world!
Mentorship, Meaning, and Career Confidence
This project is researching the connections between positive mentoring relationships, purpose in life, and how those affect undergraduate students’ confidence in what careers they decide to pursue after college. The researchers are interested in examining whether any specific qualities of mentorship, such as the duration of the mentorship, the role of the mentor, frequency of contact, and whether the mentor-mentee relationship was natural or assigned, influence purpose or career confidence. The researchers will be collecting both quantitative and qualitative data to answer their questions.
