If we focus too much on content, we ignore what we know about how our associative brain comes to makes sense new information. Think about how many people respond before reading past the first sentence of an email, or how a magazine article doesn't get the same reaction when displayed in HTML. Or consider how knowing the author of a publication influences your judgement of that content.
Picking up from the session Stephen P. Anderson gave last year on "The Stories We Construct" (a biological look at the narratives that influence behavior), this session focuses on how we come to perceive—and respond to— information. From phantom limbs to magicians fooling our senses, Stephen proposes a model that makes sense of how we truly experience information. Practical? You'll leave with a deep understanding of everything UX is about and an awareness of common practices that don't account for this knowledge.
