SUMMARY******We are defined by our cognitive abilities of attending, learning, and remembering: They make us who we are. These overarching abilities are in turn made up of processesthe building blocks of our abilitiesthat we can use to select, encode, and retrieve information. Consequently, the fluency of these processes determines how well we manage and use information and how much we benefit from experience. An obvious example of this general principle is the development of our language skills through extensive practice, and the phenomenal facility that young children so quickly develop.***This proposal describes two streams of a continuing program of research that has as its goal the understanding of fluent information processing. To accomplish this, we need “tools” to understand how basic processes work. To provide fundamental insight into the operation of cognitive processes, research on attention, learning, and memory relies heavily on how processes work together (facilitation) or compete (interference). When does prior experience help and when does it hurt our current processing? Irrelevant information must be ignored; if not, interference (slower and more error-prone responding) results. And when previous relevant processing assists current processing, this is expressed as facilitation (faster and more accurate responding). ***The proposed learning research constitutes the first stream. Here, we will examine our ability to learn simple associations in the form of contingencies. How does an irrelevant but correlated event influence how we respond to a target event? How do we learn and use connections in the world, even when we are not intending to do so? What role do attention and awareness play in this kind of learning? New studies will explore the learning of relations in the world both at the level of behaviour and at the level of underlying brain mechanisms.***The proposed memory research constitutes the second stream. Here, we will continue to explore the production effect: improved memory for information spoken aloud (or produced in some other way) at the time of learning. We have argued that distinctiveness created during learning assists later remembering (“I remember that because I remember having said it aloud”) but does production also simply help to strengthen a memory? Does the value of production “spill over” onto other cognitive processes, such as comprehension? Again, studies will be carried out both at the behavioural and brain levels to answer these questions.***The long-term significance of my research program is a deeper understanding of fluency in the interplay of these fundamental cognitive skillsa greater overall comprehension of how we attend, learn, and remember. The knowledge gained will inform work in cognitive neuropsychology and neuroscience, and will support the development of practical applications and techniques that optimize our use of these skills. **

总结 ** 我们是由我们的认知能力来定义的，注意，学习和记忆：它们使我们成为我们。 这些支配性的能力又由过程组成，这些过程是我们选择、编码和检索信息的能力的基石。 因此，这些过程的流畅性决定了我们如何管理和使用信息，以及我们从经验中受益多少。 这一普遍原则的一个明显的例子是通过广泛的实践来发展我们的语言技能，以及幼儿如此迅速发展的非凡能力。该提案描述了两个流的一个持续的研究计划，其目标是流畅的信息处理的理解。 要做到这一点，我们需要“工具”来理解基本流程是如何工作的。 为了对认知过程的运作提供基本的见解，关于注意力、学习和记忆的研究在很大程度上依赖于过程如何协同工作（促进）或竞争（干扰）。 什么时候以前的经验对我们有帮助，什么时候它会伤害我们当前的处理过程？ 必须忽略不相关的信息;否则，会导致干扰（响应速度更慢，更容易出错）。 当先前的相关处理协助当前处理时，这被表示为促进（更快和更准确的响应）。 * 建议的学习研究是第一个方面。 在这里，我们将检查我们学习以偶然事件的形式进行简单联想的能力。 一个无关但相关的事件如何影响我们对目标事件的反应？ 我们如何学习和使用世界上的联系，即使我们不打算这样做？ 注意力和意识在这种学习中扮演什么角色？ 新的研究将在行为和潜在的大脑机制两个层面上探索对世界关系的学习。建议的记忆研究构成了第二个流。 在这里，我们将继续探索生产效应：在学习时大声说出（或以其他方式产生）的信息的记忆改善。 我们认为，在学习过程中创造的独特性有助于后来的记忆（“我记得这一点，因为我记得我大声说出来了”），但生产也只是有助于加强记忆？ 生产的价值是否“溢出”到其他认知过程中，比如理解？ 同样，将在行为和大脑两个层面上进行研究，以回答这些问题。我的研究计划的长期意义在于更深入地理解这些基本认知技能相互作用的流畅性，更全面地理解我们如何注意，学习和记忆。 所获得的知识将为认知神经心理学和神经科学的工作提供信息，并将支持优化我们使用这些技能的实际应用和技术的发展。**
