我们认为，刺激的不确定性会引发一种认知状态，这种状态可以与以前被描述为“好奇心”的概念相关联（Berlyne，1949），这种状态激励主体通过探索来减少不确定性。在两项注意力过滤任务中，我们改变了反应兼容性和刺激一致性。此外，我们还操纵刺激一致性是可预测的还是随机的。在随机呈现的条件下，一致性对兼容性的影响更加明显，这表明刺激一致性在随机环境中得到更强的处理。虽然从实验室的短期战略角度来看，这毫无意义，但这种对不确定刺激条件的关注分配在实验室外却是完全有意义的。不确定性对注意力控制的影响不应被视为泄漏，而应被视为对未来可能机会的投资。
We argue that stimulus uncertainty induces a cognitive state that can be linked to a concept that has been formerly described as 'curiosity' (Berlyne, 1949) a state that motivates the agent to reduce the uncertainty by exploring it. In two attention filtering tasks we varied response compatibility and stimulus congruency. In addition, we manipulated whether stimulus congruency was predictable or random. In conditions with random presentation the impact of congruency on compatibility was more pronounced suggesting that stimulus congruency was processed more strongly in a random environment. While this makes no sense from a short term strategic perspective in the laboratory, this allocation of attention to uncertain stimulus conditions makes perfect sense outside the laboratory. The impact of uncertainty on attentional control should not be considered a leakage but rather an investment into possible future opportunities.
