Handedness and mathematical skills

11 May

According to a press release from the University of Liverpool:

“Psychologists from the University of Liverpool and the University of Milan conducted a study involving more than 2,000 students in Italy aged between six to 17 years and asked them to complete a number of mathematical tasks, including simple arithmetic and problem-solving.

In the study, the participants’ degree of handedness was ascertained by the Edinburgh Handedness Inventory, a questionnaire assessing how much an individual is right- or left-handed (or ambidextrous). The researchers then analysed the results in relation to the extent to which they were right or left-handed.

Liverpool psychologist, Giovanni Sala, who conducted the study, said: “This study found there is a moderate, yet significant, correlation between handedness and mathematical skill. Moreover, the amount of variance in the maths scores explained by handedness was about 5-10%, a surprisingly high percentage for a variable like handedness.”

This was a conference paper, I will reserve judgment until I read the actual research.

 

Note: This video claims that Gandhi was left handed. When I looked on line for images of him writing, the ones I could find show him writing with his right hand. Of course, it’s always possible that the images were flipped. Does anyone know a credible source about Gandhi’s handedness?
