Video game players may get an unexpected benefit from blowing away bad guys

better vision.
Playing “action” video games improves a visual ability _51_ tasks like
reading and driving at night, a new study says. This ability, called contrast sensitivity
function, allows people to discern even subtle changes _52_ gray against a uniformly
colored backdrop. It’s also one of the first visual aptitudes to fade with age. _53_ a
regular regimen of action video game training can provide long-lasting visual power,
according to work led by Daphne Bavelier of the University of Rochester.
Previous research shows that gaming improves other visual skills, such as the ability
to track several objects at the same time and _54_ attention to a series of fast-moving
events. Bavelier said, “a lot of different aspects of the visual system are being enhanced, 醫學考博完形強化醫學考博完形解析—連俊霞
_55_.”
The new work suggests that playing video games could someday become part of
vision-correction treatments, which currently rely mainly on surgery or corrective lenses.
“_56_ you’ve had eye surgery or get corrective lenses, exposing yourself to these games
should help the optical system to recover faster and better, you need to retrain the brain
to make use of the better, crisper information that’s coming in _57_ your improved
eyesight”.
Expert action gamers in the study played first-person shooters Unreal Tournament
2004 and Call of Duty 2. A group of experienced nonaction gamers played The Sims 2, a
“life simulation” video game. The players of nonaction video games didn’t see the same
vision _58_, the study says. Bavelier and others are now trying to figure out exactly why
action games _59_ seem to sharpen visual skill. It may be that locating enemies and
aiming accurately is a strenuous, strength-building workout for the eyes, she said
another possible _60_ is that the unpredictable, fast-changing environment of the
typical action game requires players to constantly monitor entire landscapes and analyze
optical data quickly.
