ScienceDaily (May 12, 2009) - A research project at the University of Gothenburg has been testing large groups of 13-year-olds in Sweden since the early 1960s using the same intelligence test. The tests have taken place at approximately five year intervals and consist of an inductive-logic test, a verbal test and a spatial test. Crucial factor The most recent study, which was reported in the new issue of Journal of Swedish Educational Research, shows that today's teenagers are achieving demonstrably better results in the logic test than was the case fifty years ago. This is positive as logic is a crucial factor for achievement in mathematics. "With regard to pupils chances of assimilating maths teaching, there is thus nothing to indicate that the preconditions have deteriorated in recent decades," says Professor Allan Svensson at the Department of Education.

NEW YORK (Reuters Health) - New research suggests that low vitamin D levels in the body are associated with thinking or "cognitive" impairments in older men, but whether vitamin D supplements can help is not yet known. In the study, an investigation of European men, subjects with low levels of vitamin D scored worse on a standard test of cognitive ability than did their peers with normal levels, Dr. David M. Lee, from the University of Manchester, UK, and co-researchers found. Although, the authors emphasize, the difference in scores was not that great.
