Welcome to the University of Michigan’s Cognitive Neuroimaging Lab.
Working memory is an integral part of our everyday lives, so much so that most of the time we are not even aware it is at work. Our aim in the Jonides Lab is to better understand the mechanisms and underlying processes that contribute to working memory and to executive processes that operate on the contents of working memory. The majority of our work is concerned with the storage of information in working memory, as well as with executive functions of working memory. Our tasks are intended to study the processes by which participants allocate attention selectively to information in their environment as well as those used to switch attention from one piece of information to another, or inhibit attention to irrelevant information. Also, our lab is interested in individual differences in working memory and how these predict cognitive performance, especially concentrating in how training working memory and executive processing may change performance in cognitive tasks. We are also studying how transcranial direct current stimulation (tDCS) can modify the effects of cognitive training, both for working memory and for other cognitive functions.
Our understanding of working memory and executive processes has substantial impact on understanding a variety of human states. For example, we have been studying changes in executive processing that accompany a variety of pathologies including ADHD, inability to delay gratification, and general susceptibility to distraction. Our work will continue to have translational impact on these and other human conditions that involve changes in cognitive control and working memory.
