His work asks questions like: Why do sudden signals sometimes sharpen our focus and other times make us more distractible? How does the mind decide which sights or sounds break through into awareness while others remain unnoticed? And how do memory, culture, and emotional content shape what we perceive? By designing experiments that test how attention, perception, and memory interact in real time, Kahan&#8217;s studies reveal the hidden processes that allow us to read words, recognize objects, or spot changes in a busy scene. This research helps psychologists understand the workings of the mind and sheds light on practical challenges people face, like staying focused amid distractions and competing demands on attention.<\/p>\n<h3>Summary of Interests<\/h3>\n<ul>\n<li>Visual perception and masking<\/li>\n<\/ul>\n<ul>\n<li>Word recognition processes involved in reading<\/li>\n<\/ul>\n<ul>\n<li>Selective attention<\/li>\n<\/ul>\n<ul>\n<li>Semantic priming<\/li>\n<\/ul>\n<ul>\n<li>Implicit and explicit memory<\/li>\n<\/ul>\n<h3>Education<\/h3>\n<ul>\n<li>B.S.
