Brain Scans May Help Guide Career Choice
General aptitude tests and specific mental ability tests are important tools for vocational guidance. Researchers are now asking whether performance on such tests is based on differences in brain structure, and if so, can brain scans be helpful in choosing a career? In a first step, researchers writing in the open access journal BMC Research Notes have investigated how well eight tests used in vocational guidance correlate to gray matter in areas throughout the brain.
Richard Haier, from the University of California, USA, worked with a team of researchers to investigate the neurological basis for performance on each of the tests. He said, "Individual differences in cognitive abilities provide information that is valuable for vocational guidance. There is some debate, however, as to whether results on individual tests of specific abilities may be more helpful than results on tests of broader factors, like general intelligence. We compared brain networks identified using scores on broad cognitive ability tests to those identified by using specific cognitive tests to determine whether these relatively broad and narrow approaches yield similar results".
