Expert fighter pilots are not built the same as you or I.
The researchers found that fighter pilots have superior cognitive control, showing significantly greater accuracy on one of the cognitive tasks, despite being more sensitive to irrelevant, distracting information. The MRI scans revealed differences between pilots and controls in the microstructure of white matter in the right hemisphere of the brain.
"We were interested in the pilots because they're often operating at the limits of human cognitive capability -- they are an expert group making precision choices at high speed.
The study tasks were designed to assess the influence of distracting information and the ability to update a response plan in the presence of conflicting visual information. In the first task, participants had to press a right or left arrow key in response to the direction of an arrow on a screen in front of them, which was flanked by other distracting arrows pointing in different directions. In the second task, they had to respond as quickly as possible to a 'go' signal, unless they were instructed to change their plan before they had even made a response.
The results of the first task showed that the expert pilots were more accurate than age-matched volunteers, with no significant difference in reaction time -- so, the pilots were able to perform the task at the same speed but with significantly higher accuracy. In the second task, there was no significant difference between the pilots and volunteers, which the authors say suggests that expertise in cognitive control may be highly specialised, highly particular to specific tasks and not simply associated with overall enhanced performance.
