Researchers from the University of Melbourne determined that taking a quick break and looking at natural colors can significantly increase attention, focus and job performance. The researchers tested 150 university students who were randomly selected to view one of two city scenes consisting of a building with and without a flowering meadow green roof.
The two views were experienced as micro-breaks, a 30-second period that can be taken every 40 minutes. Both groups were tested before and after viewing the scene for sustained attention spans, along with a performance test upon completing a task. Subjects who looked at the scene with the verdant roof had significantly longer attention spans and fewer errors in doing their tasks.
