itwbennett writes "Researchers at the Free University of Bozen-Bolzano in Italy have found that happier programmers (or, more specifically, computer science students at the university) were significantly more likely to score higher on a problem solving assessment. The researchers first measured the emotional states of study participants using a measure devised by psychologists called the Scale of Positive and Negative Experience Affect Balance (SPANE-B) score. They then tested participants' creativity (ability to write creative photo captions) and problem-solving ability (playing the Tower of London game). The results: happiness didn't affect creativity, but did improve problem-solving ability."
