My two main areas of interest are: 1) the structure of the lexical semantic system; and 2) the representation and processing of morphologically complex words in English and other languages. To explore these areas, I use a combination of research in normal adult processing, language loss in Alzheimer's disease, and connectionist modeling.
I'm interested in how childrenand adults reason about experimental error. I'm also interested in howpeople reason when presented with potential inconsistencies in theirthinking.
I am currently a postdoc in the lab of Patricia Carpenter and Marcel Just. I am leaving at the end of the summer for a Visiting Assistant Professor position at Bryn Mawr College near Philadelphia.
I am interested in the development of children's scientific and logical reasoning. Specifically, I have been studying how young children learn two important components of logical reasoning: 1) when evidence is necessary and when it is unnecessary to solve problems and 2) how to map evidence to form correctly in order to make valid conclusions.
I received my Ph.D. from The University of Alabama at Birmingham in Biomedical Engineering in 1999. I am currently a postdoctoral associate with the Center for Cognitive Brain Imaging, working with Drs. Patricia Carpenter and Marcel Just. The project I'm working on at the moment is a verbal reasoning problem based on the brothers and sisters problem (assume someone shows you a picture and says, "Brothers and sisters I have none. This man's father is my father's son. Who is this man?").
I am interested in executive control in task switching, stimulus-response compatibility, and mental rotation. In the current project, I am looking for brain areas that might be responsible for selection of stimulus-response mapping rule in a task switching situation. The goal is to establish theoretical connection between productions from an ACT-R model of the task performance to brain regions identified from an event related fMRI study.
Research interest: cognitive development in children - exploring cognitive change using microgenetic method and testing the parallelism between developmental and microgenetic experiment triggered change.
