项目摘要
ABSTRACT
People with hearing loss might benefit greatly if they could use the visual signal to recognize
speech. Sadly, as people age, they often experience a decline in both their hearing ability and
their lipreading ability, so that at the very time their audiovisual speech perception could
maximally benefit from visual speech information, they are least able to utilize it. Understanding
the linkage between these phenomena has been a longstanding challenge for both cognitive
science and aural rehabilitation, yet we believe this linkage provides a major clue to
understanding both individual and age-related differences in everyday speech perception. Most
researchers assume that there is a distinct integration stage and that integrative ability
diminishes with age. Our most recent findings, however, suggest that differences in unimodal
performance, and not differences in integrative abilities, underlie both individual and age-related
differences in audiovisual speech perception. Accordingly, the proposed research takes the
unique approach of focusing on both the causes of individual differences in lipreading skill and
on lipreading as a cause of differences in audiovisual speech perception. For Specific Aim 1, we
will use our new feature analysis methods to predict audiovisual speech perception based on
participants' unimodal (i.e., auditory-only and vision-only) performance. We will evaluate the
relative contributions of cognitive, perceptual, and speech production abilities as well as gaze
behavior to both individual and age-related differences in vision-only and audiovisual speech
perception. For Specific Aim 2, we will use a modification of our speech detection and lipread-
yourself tasks, along with fMRI, to assess differences in the correspondence between the
phonetic representations that support speech production and perception. Finally, for Aim 3, we
will identify neural correlates of vision-only and audiovisual speech perception using fMRI. The
results from Aims 1 and 2 will help us identify the regions of interest. We will focus on premotor
areas because we hypothesize that the linkage between speech production and visual speech
perception is critical for understanding how people recognize visual speech signals, and we will
directly compare the activation in premotor cortex during both speech production and perception
using representational similarity analysis, an elegant multi-variate analytic technique. By the end
of the grant cycle, our goal is to have developed a unified neurocognitive framework for
understanding both individual and age-related differences in lipreading and audiovisual speech
perception. This framework and our experimental results will also provide evidence-based
guidance for both speech perception training and aural rehabilitation counselling.
摘要
如果听力损失的人能够使用视觉信号来识别,
演讲可悲的是,随着年龄的增长,人们的听力和听觉能力往往会下降,
他们的唇读能力,所以在同一时间,他们的视听言语感知,
然而,当他们最大限度地从视觉语音信息中受益时,他们最不能够利用它。
这些现象之间的联系一直是一个长期的挑战,
科学和听力康复,但我们相信这种联系提供了一个主要线索,
理解日常言语感知中的个体差异和年龄差异。最
研究者认为存在一个明显的整合阶段,
随着年龄的增长而减少。然而,我们最近的研究结果表明,
表现,而不是综合能力的差异,是个人和年龄相关的基础。
视听言语感知的差异。因此,拟议的研究采取了
一种独特的方法,既关注唇读技能个体差异的原因,
唇读作为视听言语感知差异的原因。对于具体目标1,我们
将使用我们新的特征分析方法来预测视听语音感知,基于
参与者的单峰(即,仅视觉和仅视觉)性能。我们将评估
认知、知觉和言语产生能力以及凝视的相对贡献
行为的个体差异和年龄相关的差异,在视觉和视听言语
perception.对于具体目标2,我们将使用我们的语音检测和唇扩展的修改-
你自己的任务,沿着与功能磁共振成像,以评估差异之间的对应关系,
支持语音产生和感知的语音表征。对于目标3,我们
将使用功能磁共振成像来识别视觉和视听言语感知的神经相关性。的
目标1和2的结果将帮助我们确定感兴趣的区域。我们将专注于运动前
因为我们假设言语产生和视觉言语之间的联系
感知对于理解人们如何识别视觉语音信号至关重要,我们将
直接比较言语产生和知觉过程中运动前区皮层的激活情况
使用代表性相似性分析,一种优雅的多变量分析技术。年底
我们的目标是开发一个统一的神经认知框架,
理解唇读和视听言语的个体差异和年龄差异
perception.这一框架和我们的实验结果也将提供基于证据的
指导言语感知训练和听力康复咨询。
