Studies conducted by John W. Santrock, a specialist in educational psychology, a graduate of the University of Minnesota and a researcher at the University of Texas have measured that left-handed people tend to have outstanding visual-spatial ability and the ability to imagine three-dimensional designs. The same study found that in four professions (mathematicians, musicians, architects and artists) the percentage of left-handed people is much higher than in other professions.

Another study conducted by the University of Minnesota found that in a population of 100 thousand students to whom the United States School Readiness Test (SAT) was applied, 20% of students with higher grades were left-handed. , which doubled the total percentage of left-handers who applied the test and that was 10%.

Some other medical studies on left-handed physiological differences have been published by the British medical journal The Lancet, which states that left-handers are less likely to develop arthritis and have a larger corpus callosum, which adds to the fact that some regions of its right hemisphere are larger and that the time of transmission of signals between hemispheres is faster.
