It has been estimated that five to nine percent of school-aged children are diagnosed with dyslexia, and even adult skilled readers can experience debilitating reading impairments as a result of brain injury or disease. Many hypotheses have been proposed to explain the perceptual or cognitive dysfunctions that may underlie dyslexia, but one that has been particularly influential over the past thirty years or so is the phonological deficit hypothesis. This hypothesis states that reading deficits can often be linked to underlying problems in the way that the sound system of a reader's language is represented and processed in the brain. However, new evidence from genetics and brain imaging has come to light in recent years, and new phonological theories have been developed. With support of the National Science Foundation, a satellite conference will be held in conjunction with the annual meeting of the Society for the Scientific Study of Reading to critically examine the phonological deficit hypothesis in light of new theory and evidence. An international group of leaders in the field will discuss whether the hypothesis has stood the test of time, and how it might change as research continues to advance our understanding of reading deficits.

据估计，5%到9%的学龄儿童被诊断为阅读障碍，即使是成年的熟练读者也会因为大脑损伤或疾病而经历令人衰弱的阅读障碍。人们提出了许多假说来解释阅读障碍背后的知觉或认知功能障碍，但在过去30年左右的时间里，特别有影响力的是音位缺陷假说。这一假说指出，阅读障碍往往与潜在的问题有关，因为读者的语言的声音系统在大脑中被呈现和处理。然而，近年来，来自遗传学和脑成像的新证据浮出水面，新的音系学理论也得到了发展。在国家科学基金会的支持下，将在阅读科学研究学会年会的同时举行一次卫星会议，根据新的理论和证据对音位缺陷假说进行批判性审查。一个由该领域的领导者组成的国际小组将讨论这一假说是否经受住了时间的考验，以及随着研究继续推进我们对阅读缺陷的理解，它可能会发生怎样的变化。
