Todd S. Braver, Ph.D., Principal Investigator, Washington University

Dr. Todd Braver studies the cognitive and neural mechanisms underlying memory, attention, and controlled processing. His research approach combines computational modeling (using connectionist framework), functional neuroimaging (using fMRI and PET methods), and behavioral studies (in normal and clinical populations, and under pharmacological challenge). Ongoing projects include testing model predictions regarding (1) how the prefrontal cortex represents and maintains information in working memory; and (2) how the dopamine neurotransmitter system regulates control over these processes.

Julie S. Bugg, Ph.D., Co-Investigator, Washington University

Dr. Julie Bugg is interested in the use of cognitive control to achieve attention and memory-related goals. Her research explores the mechanisms that are used to resolve interference in conflict tasks (e.g., Stroop) and the various levels at which these mechanisms operate (e.g., list-level vs. item-specific level). Current areas of focus include: a) factors that moderate selection of top-down vs. stimulus-driven control mechanisms, b) how the presence of environmental contingencies moderates use of top-down control, and c) the differential effects of normal aging on multiple levels of cognitive control. A second line of research examines cognitive training and exercise engagement as strategies older adults can use to maintain and improve cognitive control with age.   Email Dr. Julie Bugg.

Andrew R. Conway, PH.D., CO-Investigator, claremont graduate university

Dr. Andrew R. A. Conway is a Professor of Psychology in the Division of Behavioral and Organizational Sciences at Claremont Graduate University. Dr. Conway’s research is aimed at understanding individual differences in intelligence and working memory capacity. People differ in their cognitive abilities and these differences matter in life, in terms of academic achievement, job performance, income, health, and happiness. Dr. Conway’s research is concerned with how cognitive abilities are measured and what role they play in various real-world cognitive tasks such as learning new information, reading and listening comprehension, and decision-making.   Email Dr. Andrew Conway.
