Description of Research

Summary Statement of Research Interests

My research focuses on cognitive training programs that improve critical thinking skills and intelligence. More specifically, I am investigating the impact of improving working memory capacity on fluid intelligence. My goal is to eventually determine whether improving working memory capacity improves real-world skills such as taking notes, taking tests, and everyday memory. Another area of my research is applying the science of learning to help improve learning and instruction for adult learners. I am currently creating a multimedia document with an undergraduate student. The document will contain a list of 15 principles of learning that can be applied to teaching psychology courses. More recently, I have started to develop an assessment to measure a person's level of superstitious beliefs. The goal of this research is to determine how superstitious beliefs influence decision making. Finally, I also dabble in other areas of research such as sex differences in cognitive abilities and sensation and perception.
