A multi-faceted study of attention

这个建议继续了我对负责注意的系统和那些负责更高层次处理的系统的研究，比如对意义和“对象”的识别。“这项赠款申请侧重于两个方向的互动。 首先，注意力的分配（或缺乏注意力）如何影响我们处理意义的能力？ 虽然长期以来的观点是，识别一个词的含义是某种自动的，可以在没有注意力的情况下完成，但我实验室最近的工作正在挑战这种观点。 第二个问题，也是很大程度上被忽视的问题是，语义计算和对象形成过程是否对注意力的运作产生影响。 注意力的范围和激活取决于加工的产品吗？ 最后，我还提出了一个新的研究路线，旨在调查的可靠性和注意加工的个体差异。这些问题是在既定的范例和程序的背景下调查的（例如，选择，外源性和内源性线索，语义启动，双任务，视觉搜索）。 我的贡献是将这些已建立的范式和联合收割机以新颖的方式结合起来，提出以前没有解决过的问题。 在这些领域的试点工作表明，这些问题的答案将迫使我们重新评估一些目前的理论帐户的基础上的注意力对更高层次的过程的影响，并将进一步我们的注意力处理的性质的理解。

This proposal continues my study of the systems responsible for attention and those responsible for higher level processing such as the recognition of meaning and "objectness." This grant application focuses on the interaction from two directions. First, how does the allocation of attention (or lack of it) affect our ability to process meaning? Although the longstanding view has been that recognizing a word's meaning is somehow automatic and can be accomplished in the absence of attention, recent work from my lab is challenging this view. The second, and largely neglected, issue is whether processes involved in the computation of semantics and object formation have consequences for the operation of attention. Does the scope and activation of attention depend on the products of processing? Finally, I also present a novel line of research aimed at investigating reliability and individual differences in attentional processing. These questions are investigated in the context of established paradigms and procedures (e.g., selection, exogenous and endogenous cueing, semantic priming, dual-task, visual search). My contribution is to take these established paradigms and combine them in novel ways to ask questions that have not been previously addressed. Pilot work in these areas suggests that the answers to these questions will force us to re-evaluate the underpinnings of a number of current theoretical accounts of the effects of attention on higher level processes, and will further our understanding of the nature of attentional processing.
