Left-handed people feel more fear than right-handers, recent research revealed.

In a test reported by the Telegraph Sunday, people were asked to watch an eight-minute video clip from “Silence of the Lambs” and recall scenes from the horror thriller.

The left-handed participants remembered only fragments of the scenes and their descriptions about them were filled with more repetition, showing symptoms of suffering from Post Traumatic Stress Disorder.

“The prevalence of PTSD is almost double in left-handers compared to right-handers,” said Dr. Carolyn Choudhary who led the research at Queen Margaret University in Edinburgh. She believes the finding could provide insights into how people develop PTSD and how the brain deals with fear.

“It is apparent the two sides of the brain have different roles in PTSD and the right-hand side of the brain seems to be involved in fear. In people who are left handed, the right side of their brain is dominant, so it may have something to do with that,” explained Dr. Choudhary.

She will present the results at the annual conference of the British Psychology Society this week.
