My research emphasizes two parallel lines of inquiry, one from the perspective of comparative psychology (cognition as it is manifest across species) and the other from the perspective of human factors (individual differences in cognition and performance). These two perspectives complement one another in analysis of the psychological processes that I currently study: attention/executive function, and learning/training. Thus, recent experiments include studies of individual and group differences in attention profiles, comparative and psychometric studies of uncertainty monitoring, procedures that improve the effectiveness of computer-based instruction, the effects of spaceflight on behavior and performance, psychophysiological and cognitive predictors of vigilance, and the cognitive profiles of individuals who excel in detecting threat items in X-ray images of airport baggage.
This broad program of research stems from support provided by the National Institute of Child Health and Human Development, the National Aeronautics and Space Administration, the Federal Aviation Administration, the McDonnell-Pew Foundation, the Department of Defense (ARI, ARO, AFOSR, ONR, and USAMRMC), and Georgia State University and enjoys the collaboration of outstanding behavioral scientists from GSU and around the world. With laboratory resources including eye-trackers and transcranial Doppler sonography in the Individual Differences in Executive Attention (IDEA) laboratory, to the unique monkeys and apes available for study at the Sonny Carter Life Sciences Laboratory and the Language Research Center, there are many opportunities for collaboration and participation by other scientists and graduate or undergraduate students.
These research opportunities are well illustrated by the program-project grant from NICHD, "Biobehavioral Foundations & the Development of Cognitive Competence" (HD060563). This multi-institutional, multi-disciplinary research project (as well as P01-HD38051, funded by NICHD from 2003-2011) is designed and funded to examine the emergence across species and developmental periods of executive attention, relational learning, numeric and symbolic processing, spatial problem-solving, and metacognition. Additionally, we are using brain-imaging technology including fMRI, transcranial magnetic stimulation, and transcranial doppler sonography to identify the brain mechanisms that correspond to each of these cognitive processes.
