"In recent years anthropologists have begun to point out that sensory perception is culturally specific. "Sensory perception," Constance Classen, the author of "The Deepest Sense: A Cultural History of Touch," says, "is a cultural as well as physical act." It's a controversial claim made famous by Marshall McLuhan's insistence that nonliterate societies were governed by spoken words and sound, while literate societies experienced words visually and so were dominated by sight. Few anthropologists would accept that straightforwardly today. But more and more are willing to argue that sensory perception is as much about the cultural training of attention as it is about biological capacity."

"One of the most fascinating examples of heuristics and biases is what we call intuition - a complex cluster of cognitive processes, sometimes helpful but often misleading. Kahneman notes that thoughts come to mind in one of two ways: Either by "orderly computation," which involves a series of stages of remembering rules and then applying them, or by perception, an evolutionary function that allows us to predict outcomes based on what we're perceiving. (For instance, seeing a woman's angry face helps us predict the general sentiment and disposition of what she's about to say.) It is the latter mode that precipitates intuition. Kahneman explains the interplay:"

"The long-held theory helped to explain a part of the hearing process called "adaptation," or how humans can hear everything from the drop of a pin to a jet engine blast with high acuity, without pain or damage to the ear. Its overturning could have significant impact on future research for treating hearing loss, said Anthony Ricci, PhD, the Edward C. and Amy H. Sewall Professor of Otolaryngology and senior author of the study."

"Some museum exhibitions put up disclaimers about sex. Others warn about violence in their art. The impressive Andy Warhol show that opens today at the Corcoran Gallery of Art ought to begin with a big sign that reads something like this: "The following exhibition may cause depression or anxi"

"The premise here is that if brains somehow sustain the mind and we deconstruct the brain in detail and we put the information back together in powerful computers, we should be able to recreate consciousness from computer code. Or such is the hope, anyway. Since the brain integrates external stimuli to give us our experience of reality, would simulated brains be able to recreate reality? And if so, could we be fooled by a simulation, unable to distinguish reality and fantasy?"
