Lefties are prone to inhibition and anxiety

London, Nov 4 (ANI): Lefties not only find it difficult dealing with a world designed for right-handers, but are also prone to inhibition and anxiety, a new research suggests.

According to Lynn Wright, a behavioural psychologist at the University of Abertay Dundee, UK, who led the study, when left-handers start doing something, they tend to dither.

Right-handers tend to jump in a bit, New Scientist quoted the expert, as saying.

The research team came to the conclusion, after conducting tests of behavioural inhibition. They found 46 left-handed men and women scored higher than 66 right-handers. Women, too, tended to rack up higher scores on the tests of reticence.

The boffins identified these predilections by giving subjects a behavioural test that gauges both personal restraint and impulsiveness, qualities which seem to emanate from opposite hemispheres of our brains.

Compared to right-handers, lefties and women were likelier to agree with statements such as, I worry about making mistakes and Criticism or scolding hurts me quite a bit.

All groups responded similarly to statements such as I often act on the spur of the moment and I crave excitement and new sensations, the research team found.

According to Wright, the results could be due to wiring differences in the brains of left-handers and right-handers.

Research suggests that handedness is a matter of degree. But in left-handers the right half of the brain is dominant, and it is this side that seems to control negative aspects of emotion. In right-handers the left-brain dominates.

The study has been published in the journal Personality and Individual Differences. (ANI)
