Shoot-'em-ups

このところ，あるものの企画のためのアイデアが枯渇し，４日間も停滞しているUGです（最近，顔をまったく見せないL-bowや風に）。ビデオゲームのうち，shoot-'em-upsの種類が，実は認知面にはよい影響を与えるという大学の研究結果をNYTが掲載していました。
停滞しているわが身としては，すんなりと納得しそうです。あー，shooting gamesならぬ，卓球でもしてこようかいな。ところで青字部分をgachaはどう訳しますか。（UG）
Shoot-'em-ups are good for you, say researchers

For many parents they are little more than the source of our children's tantrums, feet-stomping and long periods of hibernation in stuffy rooms behind locked doors.
Yet a new study into the effects of computer games has revealed that fast-paced action games turn us into faster and better decision-makers.
Scientists at the University of Rochester in New York conducted a series of tests to gauge whether regular bouts of high-speed gaming could help to improve our cognitive abilities.
The first group were told to play adrenalin-packed action games such as Call of Duty 2 and Unreal Tournament, in which participants dash around online arenas shooting each other.
The second group were given The Sims 2, a more sedate, strategy-based game that mimics the pace of everyday life.
After 50 hours of playing, both groups were given a series of tests to see whether they could make quicker decisions.
Scientists discovered that those who had trained on the action games made decisions 25 per cent faster than their counterparts. They also answered just as many questions correctly as their strategy game-playing peers.
"It's not the case that the action game players are trigger-happy and less accurate – they are just as accurate and also faster," said Daphne Bavelier, a cognitive scientist at Rochester who has been testing how computer games affect the brain and eyes for much of the past 10 years. "Action game players make more correct decisions per unit time. If you are a surgeon or you are in the middle of a battlefield, that can make all the difference."
The findings are significant because they suggest how some computer games – often vilified for turning people into couch potatoes – help players to develop a heightened sensitivity to what is going on around them.
This benefit, researchers suggest in a forthcoming edition of Current Biology, has repercussions in the real world, such as improving our ability to multitask, drive, read small print and keep track of friends in a crowd.
