Not surprisingly, the vast majority of people (92 percent) quickly solve this problem, as it requires a standard problem-solving approach in which only the answer is altered. What’s perhaps a bit more surprising is that nearly 90 percent of patients with brain damage to the prefrontal lobes — this leaves them with severe attentional deficits, unable to control their mental spotlight — are also able to find the answer …
