Dr. Jeffrey Zacks
People perceive and conceive of activity in terms of discrete events, even though the world as presented to human sense organs is continuous, dynamic, and fleeting. In this talk I will present a theory of why this occurs and what it means for understanding and memory. According to the theory, the perception of events depends on physical cues, and also on cognitive representations that capture parts, goals, and plans. I’ll describe converging behavioral, neuropsychological, and neurophysiological data supporting the theory, and discuss some implications for attention, memory, and cognitive aging.
