摘要翻译：
我们考虑一个决策者(DM)，在采取行动之前，她通过动态地将有限的注意力分配到不同的新闻来源上来寻找信息，这些新闻来源偏向于替代行动。信息的内生选择产生了丰富的动力：选择的新闻来源要么强化要么削弱先前的信息，塑造了随后的注意力选择、信念更新和最终行动。当信念是极端的时，DM采用偏向当前信念的学习策略，当信念是适度的时，DM采用反对当前信念的学习策略。应用于新闻媒体消费，观察到的行为对党派选民表现出“回声室”效应，对温和派表现出新的“反回声室”效应。

英文摘要：
We consider a decision maker (DM) who, before taking an action, seeks information by allocating her limited attention dynamically over different news sources that are biased toward alternative actions. Endogenous choice of information generates rich dynamics: The chosen news source either reinforces or weakens the prior, shaping subsequent attention choices, belief updating, and the final action. The DM adopts a learning strategy biased toward the current belief when the belief is extreme and against that belief when it is moderate. Applied to consumption of news media, observed behavior exhibits an `echo-chamber' effect for partisan voters and a novel `anti echo-chamber' effect for moderates.
