Research Interests and Publications

Research in Dr. Unsworth's laboratory combines experimental and differential approaches to cognition in order to examine basic memory and attention processes and their role in higher-order cognition. Specifically, we are interested in individual differences in memory and attention capabilities and their relation to higher-order cognitive processes (such as intelligence and reasoning).  Our current work explores two functional characteristics of working memory: the need to actively maintain information in the face of distraction and the need to retrieve information that could not be maintained. It is argued that both functions are needed in a host of cognitive activities, but to differing degrees based on task demands.  Finally, work in the laboratory is aimed at better understanding search and retrieval dynamics in recall. 

Dr. Unsworth will not be accepting master's students for Fall 2017.
