The photo above displays a breakfast spread.Readers have eighteen seconds to spot three differences between the photographs.
While some of the distinctions may be obvious to the unaided eye, others may require close examination to be identified.
Because of this, readers must be extremely focused in order to distinguish the variations between the two images.
According to studies, these kinds of activities activate the parts of the brain linked to memory and focus.
Well done to the readers who succeeded in doing so. Your eyes are the sharpest, people.
