"Jeffrey Zacks"

My lab studies perception and cognition using the methods of experimental psychology and neuroscience. One of our primary interests is in how people parse ongoing activity into meaningful events. The sensory world has been described as "a blooming, buzzing confusion," yet we seem to talk and think about activity as consisting of a modest number of discrete events. My lab's work suggests that this is so because specialized brain systems form stable representations that chunk intervals of time into coherent events, and chunk events into larger super-events. This segmentation is adaptive—people who don't segment activity very well also don't remember it as well later.
