Left Handedness Linked With Shyness

New research points a finger to left-handed people who are more likely to get anxious or feel shy or embarrassed about saying or acting on what they want.

Researchers at Abertay University gave the study participants a behavioral test that gauges personal restraint and impulsiveness.

Left-handers agreed more with statements such as "I worry about making mistakes."

They also noted in the test that "criticism or scolding hurts me quite a bit."

Dr Lynn Wright, who led the study in Dundee, believes the results could be attributed to wiring differences in the brains of left and right-handers.

"Left-handers are more likely to hesitate whereas right-handers tend to jump in a bit more," she said.

In total, the study compared 46 left-handed people with 66 right-handers.

Left handed people display more inhibition, especially when a situation was new or unusual.

The study found women acted more held back than men.

All groups responded similarly to statements like, "I often act on the spur of the moment" and "I crave excitement and new sensations."

"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", said Wright.
