The process of learning requires the sophisticated ability to constantly update our expectations of future rewards so we may make accurate predictions about those rewards in the face of a changing environment. Although exactly how the brain orchestrates this process remains unclear, a new study by researchers at the California Institute of Technology (Caltech) suggests […]
In a study appearing in the journal PLoS ONE, Massachusetts General Hospital (MGH) scientists describe finding mathematical patterns underlying the way individuals unconsciously distribute their preferences regarding approaching or avoiding objects in their environment. These patterns appear to meet the strict criteria used to determine whether something is a scientific law and, if confirmed in […]
Newborn infants are capable of a simple form of learning while they are asleep according to a study by researchers funded by the National Institutes of Health. The finding may one day lead to a test that can identify infants at risk for developmental disorders that do not become apparent until later in childhood. The […]
Swimsuit season is almost upon us. For most of us, the countdown has begun to lazy days lounging by the pool and relaxing on the beach. However, for some of us, the focus is not so much on sunglasses and beach balls, but how to quickly shed those final five or ten pounds in order […]
For many people, remembering to take a daily medication can be the difference between life and death. Yet, people forget all the time. Now a landmark study from North Carolina State University has found that changes in daily behavior have a significant effect on whether we remember to take our medication – and that these […]
Historical research by Peter J. Snyder, PhD, reveals more of Charles Darwin’s thinking when he completed what may be the first example of a prospective “single-blind” study of human perception of emotional expression. Through scrutiny of Darwin’s work, including previously unpublished handwritten notes on his experiments, Snyder explains how this early experiment has direct implications […]
Just seeing someone who looks sick is enough to make your immune system work harder, according to a new study in which volunteers looked at pictures of sick people. This may help fight off pathogens, says Mark Schaller from the University of British Columbia who conducted the research. “It seems like it’s probably good for […]
Scientists have long known that the brain’s frontal cortex supports concrete rule learning. Less clear is how the brain processes more complex and unfamiliar knowledge. In a paper published today (Wednesday, April 28, 2010) in the journal Neuron, a team of researchers at Brown University and the University of California–Berkeley tested whether the frontal lobe […]
