Researchers reportedly took a number of employees from a Dutch insurance firm, allowing one group to play computer games -- such as minesweeper and solitaire -- for up to one hour a day, while "restricting the others." After a month, the employees of both groups were tested, and "those who had been permitted to play games at their desk were found to be happier about their workload and performance."
The study's leader, Professor Jeffrey Goldstein, said that games such as solitaire could "help people to work better by giving their brain a rest from complex work-related tasks."
The report also stated that the scientists now "hope to repeat the study using more complicated computer games, such as strategy or combat simulations."
