The Memory and Attention Laboratory at the University of South Dakota is part of the Human Factors program in the Department of Psychology. We study memory, attention, and multitasking in humans. Our work informs current theories of how working memories are formed, the causes of forgetting, and the relationship between working memory and higher-order cognitive behavior.
Collaboration on Mathematical Models of MS Published (May 2022)
In this collaboration with Dr. Sandry's lab at Montclair State University we did some mathematical modeling to explore better ways of assessing cognitive decline in Multiple Sclerosis. We show a relationship between components of motor slowing and brain morphometry in MS patients:

Paper Accepted for Publication this week (May 2022)
A collaboration with Evie Vergauwe arguing that cognitive load and standard interference approaches fail to adequately account dual-task memory disruption. Instead we propose a new enrichment account:
