First, the volunteers walked 30 feet away while wearing a hood that blocked much of their vision. This was repeated three times, with gaits and other elements of walking measured. Although their vision was shielded and they couldn’t see the floor or their intended target, all the subjects could were easily able to reach the target using their working memories. In the next set of experiments a week later, the volunteers were split into three groups: one that performed the hooded-walk exactly as before, one that did it with the hood while talking on a cellphone, and one that did it with the hood while texting and able to see the cellphone clearly. The results showed cellphone activity clearly interfered with the subjects’ working memory. The first group performed the test as easily as they [...]
