Left-handed people consistently perform worse than right-handed people in measures of cognitive ability, or IQ, with the ‘level of disability’ equivalent to being prematurely born.

This is the finding of a recent study led by Professor Mike Nicholls (pictured), newly-appointed Director of the Brain and Cognition Laboratory in Flinders University’s School of Psychology, which dispels the common myth that left-handed people are more likely to be gifted.

“The evidence, based on our analyses of very large databases of handedness and other attributes in people across Australia, the UK and the USA, doesn’t bear out that myth,” Professor Nicholls said.

“Our study of members of the same family confirms that left-handed children will do worse than their right-handed siblings,” he said.

Professor Nicholls, who is himself left-handed, has been appointed to one of the new Strategic Professorships designed to bolster specific areas of research.

He joined Flinders in January after 17 years at the University of Melbourne.

Over that time, he was awarded seven large Australian Research Council grants for projects examining how the brain affects behaviour.

He said handedness is tied to left/right asymmetries in the brain, or laterality – a major research focus of the Laboratory.
