Citeogs more affected by fear

British psychologists have found that left-handed people are more affected by fear.

Participants of a study who write with their left hand were more likely to show post traumatic stress symptoms after watching a clip from a scary movie during research conducted by Queen Margaret University in Edinburgh, Scotland.

Dr Carolyn Choudhary said: "The prevalence of post traumatic stress disorder is almost double in left-handers compared to right-handers.

"We used a portion of film from 'Silence of the Lambs' that we know elicits fear, so we could check the recalled account against the film. People who were left-handed showed significantly more fragmentation in their memories and more repetition.

"It seems that after experiencing a fearful event, even on film, people who are left-handed had subtle behaviours that were like people suffering from post traumatic stress disorder."
