...Right now we’re developing decision-making procedures predicated on really simple control behavior—for example, avoiding obstacles or flying towards sensory stimuli,” says Wood, who is teaching Engineering Sciences 159, “Introduction to Robotics...
...forthcoming issue of the European Journal of Developmental Psychology, he and Jackson pour cold water over recent experiments that claim to have observed innate or precocious social cognition skills in infants. His own experiments indicate that a baby's fascination with physically impossible events merely reflects a response to stimuli that are novel. Data from the eye tracker and the measurement of the pupils (which widen in response to arousal or interest) show that impossible events involving familiar objects are no more interesting than possible events involving novel objects. In other words, when Daniel has seen the red train come...
...paint contains synthetic replicas of chemicals characteristic of the sweat generated by individuals with varying chronic phobias. Over the course of five years, Tolaas gained the trust of the nine men whose body odors are featured in the exhibit, collecting their sweat after they were exposed to fear-inducing stimuli. Using advanced technology, the scents were analyzed and reproduced in chemical form. These chemicals in turn were mixed into wall paint through a process called microencapsulation—a descendant of Scratch-n-Sniff technology—which releases odors when the paint is rubbed or scratched. The reactions...
Brain scanning is the field's dominant technology, but others are used as well, often in conjunction with fMRIs. Magnetoencephalography (MEG), a technology that can read electrical signals pulsating from brain cells, is popular because it detects how quickly the brain reacts to stimuli. But unlike fMRI scans, MEG can't identify which parts of the brain are reacting. And that's important, since researchers say it's the interplay between the deeper, older, primitive brain, where our emotions reside, and the more logical neocortex, which informs our decision making. And because the dance between the old- and new-brain...
...back on a back-board (a flat piece of plywood that makes chest compressions more effective than they are on a soft bed). She had no palpable pulse and the nurses couldn't get a blood pressure, but she was still weakly responsive to noxious stimuli. This is the medical term for stuff that bothers...
