Karen Arnell

Karen Arnell is a Professor of Psychology at Brock University, holding a Ph.D. from the University of Waterloo. Her research focuses on cognitive psychology, particularly attention mechanisms including multi-tasking, attentional distraction, emotion-attention interactions, and electrophysiological correlates of attentional processes. She leads a research lab investigating individual differences in cognitive control and attentional breadth.

Her work employs methodologies such as EEG/ERP to explore how affective states, motivational factors, and self-control influence attentional processing. Representative topics include reward effects on Stroop performance, hyper-binding phenomena, and the neurophysiological underpinnings of attentional modulation across age groups.

Publications span experimental paradigms like attentional blink, global-local processing, and rapid serial visual presentation, emphasizing individual variability in cognitive performance. While no specific awards are listed, her extensive research contributions reflect sustained engagement in cognitive and affective neuroscience domains.
