Given the importance of reading in our everyday life and the increased need to understand reading disabilities such as dyslexia, it is critical that we gain a better understanding of how the brain's hemispheres communicate when we read.  With this understanding more effective intervention strategies can be developed to better help people who struggle with reading.For most of us, it is likely that the left hemisphere of the brain is performing much of the work during reading.  However, recent evidence suggests that the right hemisphere does have some reading ability.  It remains to be determined just how this ability affects reading efficiency.  For instance, does the right hemisphere facilitate, inhibit, or have little effect on the more efficient left hemisphere processing?My research investigates this question using a procedure that measures whether two hemispheres are better, worse, or not different from one.  Moreover, the procedure lends well to tests of people who are slow readers, so can be used to map ways in which communication is normal or abnormal in people with a reading problem.  To date, the answers that I have obtained suggest that competent reading is associated with the gradual shutting down of processing by the right hemisphere, and that this does not consistently happen in people with a reading disability such as dyslexia.My plan is to continue to identify factors that affect how the hemispheres communicate when people read.  Does the communication differ if you are a new reader compared to an experienced one?  Does it differ if you have a reading disability?  What are text factors that promote the hemispheres to work together or work against each other?  My goal is to map the dynamics of interhemispheric communication so that we can better help people who have difficulty reading.

鉴于阅读在我们日常生活中的重要性，以及对阅读障碍等阅读障碍的了解日益增加，我们更好地了解大脑半球在阅读时是如何交流的至关重要。有了这种了解，可以制定更有效的干预策略，以更好地帮助阅读困难的人。对我们大多数人来说，在阅读的过程中，大脑的左半球很可能承担了大部分工作。然而，最近的证据表明，右半球确实具有一定的阅读能力。这种能力如何影响阅读效率还有待确定。例如，右半球是促进、抑制还是对更有效的左半球的处理几乎没有影响？我的研究使用了一个程序来调查这个问题，该程序衡量两个半球是否更好，更差，或者与一个半球没有什么不同。此外，该程序很适合测试阅读速度慢的人，因此可以用来绘制有阅读问题的人的正常或异常交流方式。到目前为止，我得到的答案表明，合格的阅读与右半球逐渐关闭的处理有关，而这并不总是发生在有阅读障碍的人身上，比如阅读障碍。我的计划是继续确定人们阅读时影响大脑半球交流的因素。如果你不阅读，与有经验的读者相比，新读者是什么？ 如果你有阅读障碍，这有什么不同吗？ 什么是促使两个半球协同工作或相互对抗的文本因素？ 我的目标是绘制大脑半球间交流的动态图，这样我们就可以更好地帮助那些有阅读困难的人。
