Neuroscience may seem like a subject best reserved for college. Two Temple psychologists propose that it be much earlier — as in first grade. In a study published this month, Peter Marshall and Christina Comalli discovered that children knew less than expected about the brain. So the researchers designed a 20-minute lesson about the brain and delivered it to a group of first-grade students. Even this brief intervention, they reported, "was enough to improve their knowledge of brain functioning as assessed three weeks later."
