We study the impact of manipulating the attention of a decision-maker who learns sequentially about a number of items before making a choice. Under natural assumptions on the decision-maker's strategy, directing attention toward one item increases its likelihood of being chosen regardless of its value. This result applies when the decision-maker can reject all items in favor of an outside option with known value; if no outside option is available, the direction of the effect of manipulation depends on the value of the item. A similar result applies to manipulation of choices in bandit problems.

请注意！

我们研究了操纵决策者注意力的影响，决策者在做出选择之前按顺序学习许多项目。在决策者策略的自然假设下，将注意力集中在一个项目上会增加其被选中的可能性，而不管其价值如何。当决策者可以拒绝所有项目而支持具有已知价值的外部选项时，此结果适用；如果没有可用的外部选项，则操纵效果的方向取决于项目的价值。类似的结果适用于老虎机问题中的选择操作。
