Past examples of research projects

Object Representation

Additional supervisor: Yichen Li

We are interested in how people represent objects differently when they're tracking them physically (say, to grab them) vs. to recognize them visually. In particular, this project examines the early development of this difference.

Play

Additional supervisor: Dr. Junyi Chu

What does it mean to have fun? We have collected video data of children ages 5-10 years playing with toys under different instructions: Do whatever you want, Try to have fun, Learn as much as you can. Next steps are to categorize children’s actions and test specific hypotheses about decision-making and learning. For example, do children at pursue more diverse goals when trying to have fun than when trying to learn? How might learning outcomes differ across conditions? What kinds of developmental change might we observe?

Creative Problem-Solving

Additional supervisor: Dr. Junyi Chu

How do children generate hypotheses for novel problems? We designed some brainteasers for 3-5-year-old children and will run a series of online experiments this Spring. The primary question is whether repeated exposure to such problems can support “out of the box thinking”, and how this effect might generalize across different kinds of problem.
