Reason for Slowing Down of Response Times and Decision-making Processes as One Catches Up With Age
"This 'neural noise' means that we lose neural connections, and we process information at a slower rate," said Wythe Whiting, associate professor of psychology at Washington and Lee University.
The researchers have been testing his theory in WnL's Cognitive Lab, with interesting results.
During the past two years, the researchers have compared the responses of younger adults (18 to 29 years old) with those of older adults (60 and over).
They asked the test subjects to look at a computer monitor and pick out target lines that were different from other lines.
For example, they needed to find the green line among the orange lines or the line that tilts left instead of right.
The researchers added "noise" in the form of visual static on the computer screen.
"If older adults already have, as I've hypothesized, more neural noise, and you exacerbate it by adding more noise, then the older adults should be much slower in identifying the target lines than the younger adults. Basically, the faster they identify the lines, the healthier their nervous system is," explained Whiting.
The research team found that the older adults were disproportionately more susceptible to the static noise than the younger adults.
