                                        Abhishek Dey

Abhishek is interested in the intersectionality of implicit mechanisms of control and explicit judgements and performance.  Abhishek’s previous research was involved with action control.  His master’s thesis examined the effect of instructions on implicit knowledge of the uncertainty of motor actions.  Currently, he is investigating the boundary conditions of when cognitive control mechanisms are applied to representations of categories, as opposed to representations of exemplars.  Understanding these boundary conditions would inform future research regarding stereotyping and policy-making for diversity training.  Abhishek is also looking to investigate whether (a) minute environmental shifts can be detectable, and (b) if awareness of those shifts leads to performance changes in either proactive or reactive control.

Nathaniel Diede

Nate examines the mechanisms of reactive and proactive cognitive control using behavioral, pupillometric, and internet-based methodology. His research has found that reactive control generalizes across spatially proximal regions of space, and is capable of engaging cognitive effort outside of the explicit awareness of task demands. He will be continuing this investigation by studying what information is being used to guide these adjustments in control, with a current focus on affect. Nate is also interested in how proactive and reactive control interact in situations where reactive control can be relied on to greater or lesser degrees. He has found that when incentivized, proactive control is heightened for only short periods of time in situations entailing more conflict compared to situations of less conflict. Nate will be continuing this line of research by studying how performance is affected when environmental situations change, and in situations where the environment is less reliable. Nate is also actively engaged in understanding mind wandering in old age, what control mechanisms are involved in the initiation and maintenance of mind wandering, and in general how task engagement differs in old age compared to young adulthood.

Emily joined the lab in the Fall of 2016 after earning a bachelor’s degree in psychology at Washington and Lee University in May 2016. Her bachelor’s thesis examined the impact of multitasking and divided attention on information processing and learning in an academic context. She is currently investigating how divided attention impacts prospective memory. Her research interests include aging, prospective memory, cognitive control, and attention.
