问题     A new study published in the journal Proceedings of the Royal Society B by the teams of Dr. Gregory West and Dr. Veronique Bohbot shows that【B1】______ video game players (VGPs) 【B2】______ more efficient visual attention abilities, they are【B3】______much more likely to use navigation strategies that【B4】______on the brain’s reward system and not the brain’s spatial memory system.
    Past research has shown that people who【B5】______the reward system-dependent navigation strategies have decreased grey matter and【B6】______functional brain activity in the memory system. However, the effects of intense video gaming on the brain are only beginning to be【B7】______.
    The study was conducted【B8】______a group of adult gamers who were spending at least six hours per week on this activity. " For more than a decade now, research has demonstrated that action video game players display more【B9】______visual attention abilities, and our【B10】______study has once again confirmed this【B11】______says first author Dr. Gregory West. "【B12】______ , we also found that gamers rely on the reward system to a greater【B13】______than non-gamers. Past research has shown that people who rely on the reward-system-dependent strategies have lower grey matter and functional brain activity in the hippocampus. This means that people who spend a lot of time playing video games may have【B14】______hippocampal integrity, which is associated with an increased risk of neurological disorders【B15】______Alzheimer’ s disease."
    【B16】______past research has shown video games as having positive effects on attention , it is important for future research to confirm that gaming does not have a【B17】______effect on the hippocampus. Future research using neuroimaging will be necessary to further【B18】______our current findings, and these studies should investigate the【B19】______effects of specific video games【B20】______the integrity of the reward system and hippocampus.
【B11】
选项 A、concept
B、notion
C、conception
D、theory
答案B
解析 此处指上文research has demonstrated that…部分的内容，这一部分只是某种看法。此外，notion的英文解释为an opinion or belief about a particular subject。再从最后一段看，“未来的研究来证实游戏对海马体没有负面影响很重要”。故此，选项[B]最恰当。选项[A]concept(概念)侧重于an abstract idea(抽象性)，选项[C]conception(概念的形成；想象力)侧重于the ability to imagine(富有想象力)，选项[D]theory(理论，说法)侧重于based on a lot of thinking but not on actual evidence，三个干扰项都不如选项[B]恰当。
