My area of research:
My research program in developmental and cognitive neuropsychology is focused on examining the nature of executive function, the cognitive processes mediated by the prefrontal cortex. Executive functions include such processes as planning, working memory, inhibition, flexibility, and self-monitoring. Over the years, my research has explored these processes in typical and atypical populations, the construction and validation of new assessment tools, and the degree to which interventions can facilitate executive functions in children and adults. Some of my recent research has taken a very applied approach in which I have examined the effectiveness of a thinking skills curriculum, BrainWise, for improving executive functions in very vulnerable populations, including families living in poverty, high-risk adolescents attending alternative high schools, and homeless men living in transitional housing. My research with doctoral students in Educational Psychology has identified that executive functions do, indeed, relate to some very important real-world behaviors, such as academic self-efficacy and achievement, career exploration and decision making, and risk taking.
My most recent writing and research has focused on the concepts of “cool” and “hot” executive function, in collaboration with Dr. Eric Peterson. The “cool” version of executive function involves the manner in which we have traditionally tested executive function with decontextualized, laboratory tasks, under conditions with relatively little arousal, motivation, or emotion. Alternatively, the “hot” version of executive function pertains to testing these processes under more arousing conditions that may more closely parallel our engagement of executive function skills in the real world of school, work, peers and risky situations. We are pursuing a line of research in which we look at executive function in terms of the complex relationships among task, context and person (e.g., personality factors). We are also interested in whether there are individual differences among students in executive processes that may be predictive of their progress in college and beyond.
Some of my research has been funded by the National Institutes of Health, the National Science Foundation, and the March of Dimes Birth Defects Foundation.
My teaching philosophy:
I strive to teach content-rich classes that combine both lecture and discussion formats. My goal is to link the topic area, whether it is research methods or child psychology, to current issues in society, as well as to provide students with the practical, critical thinking skills to make informed decisions about their own lives. The courses I teach typically are: Introduction to Research Methods, Advanced Research Methods, Human Growth and Development, Child and Adolescent Psychology, Developmental Disabilities and Psychopathology, as well as graduate-level courses on development.
