...Cohen Kadosh took five volunteers with normal math abilities through more than 500 trials. In an experiment published this month in Current Biology, he targeted different regions of the test subjects' brains with magnetic pulses while they performed number-recognition problems. A normal subject, when asked to identify whether a 2 or a 4 is written in larger text, will be a split-second faster on those occasions that the 4 is printed bigger. Normal subjects process that 4 is a bigger quantity than 2, and that information aids their pick - just as number recognition slows them down slightly when...
...grasp of numbers. It's fascinating, both because it reduces a serious learning disability to the mere flick of a neural switch and because, by doing so, it holds out a tantalizing possibility that one day a cure may be as simple as flicking that switch in reverse. Cohen Kadosh hopes the result will allow scientists to develop a diagnostic tool for dyscalculia based on neuroimaging. Identifying children with developmental dyscalculia would let parents intervene earlier to teach important math concepts, just as they can intervene today to help dyslexic children read better...
...years ago," says Mahesh Sharma, a professor of mathematics education at Cambridge College in Massachusetts. Indeed, even the definition is a bit fuzzy. Some researchers count disabilities in spatial perception or arithmetic operations as dyscalculia, while others restrict it to difficulty recognizing numbers normally. Cohen Kadosh's tests hold out the possibility that different math dysfunctions could well be processed elsewhere in the brain. "I won't say this study provides all the answers," says Sharma. Definitely not, but at least it helps show why, for some, two plus two equals trouble...
...game started off strong for the Crimson, with co-captain John Henry Flood winning the opening faceoff, and senior Greg Cohen scoring twice in the first seven minutes...
...spots were not bright last night, however. A number of passes for both teams seemed to get by their intended targets, including a point during the second quarter when senior attackman Greg Cohen lost a ball when he looked up to catch a routine pass in the Bears zone. Duboe wouldn’t go as far as to blame some of the sloppy play on the lights, however...
