Many workers spend hours a day in front of a QWERTY keyboard on a PC -- and now scientists have found that the keyboard itself is shaping how we react to words. People tend to react more positively to words filled with letters from the right-hand side of a QWERTY keyboard while words from the left side make people feel negative emotions. The cognitive scientists think that the effect might be caused by the fact that it's slightly easier to type with the right hand, as there are fewer letters for touch-typists on the right-hand side of the keyboard. Scientists tested how people reacted using a mix of real words, new words such as 'LOL' and even made-up words such as 'Pleek'. They found that their volunteers tended to rate ALL words more positively if they came from the right-hand side of the keyboard - but the effect was particularly pronounced with computer-era words such as 'LOL'.
