项目摘要
In many situations people have to process simultaneously presented auditory and visual
information, and this ability is especially important for lexical development where auditorily
presented words often co-occur with visually presented objects and scenes. We argue that
processing of cross-modal input depends on two critical parameters: (a) the speed of orienting to a
modality relative to the competing modality and (b) the dwell time of attention. We also argue that
both parameters undergo developmental change, which results in faster and more efficient
processing of cross-modal input. Based on these ideas, we propose a project that (a) estimates
the critical parameters of auditory-visual processing (Study 1) and (b) uses these parameters to
understand the ability to extract the structure from visual input, such as category learning or
learning of correlations (Study 2). The major innovation of the proposed research is the theoretical
proposal linking some important aspects of cognitive development to more basic mechanism(s)
underlying cross-modal processing. The proposed project has two specific aims. Specific aim 1 is
to determine how auditory input affects attention allocated to corresponding visual input and to
develop a modality-independent measure capable of examining auditory, visual and cross-modal
processing. Specific aim 2 is to directly test the ability of attentional mechanisms underlying crossmodal
processing to account for effects of auditory input on the ability to extract statistical structure
from visual input. The experiments will be guided by our hypothesis that the attentional mechanism
underlying cross-modal processing can account for performance on higher-order cognitive tasks,
which require processing of visual structure such as word learning, category learning and learning
of multiple contingencies. Each study will include multiple experiments with 8-, 12- and 16-monthold
infants and will include a variety of methodologies. The proposed research is important
because it will generate new knowledge affecting our understanding of the development of
attention and its role in cross-modal processing, thus revealing some basic mechanisms of early
lexical and cognitive development. This knowledge may also have broader impact on the clinical
community by elucidating factors underlying Specific Language Impairments (SLI).
在许多情况下,人们必须同时处理听觉和视觉
信息,这种能力对于词汇开发尤其重要
呈现的单词通常与视觉上呈现的对象和场景共同发生。我们争论
跨模式输入的处理取决于两个关键参数:(a)定向速度
相对于竞争方式和(b)关注时间的方式。我们也认为
这两个参数都经历了发展变化,这会导致更快,更有效
跨模式输入的处理。基于这些想法,我们提出了一个项目,该项目(a)估计
听觉 - 视觉处理的关键参数(研究1)和(b)使用这些参数
了解从视觉输入中提取结构的能力,例如类别学习或
相关性学习(研究2)。拟议研究的主要创新是理论
提案将认知发展的某些重要方面与更基本的机制联系起来
基础跨模式处理。拟议的项目有两个具体的目标。具体目标1是
确定听觉输入如何影响分配给相应的视觉输入的注意力和
开发一种独立于模态的措施,能够检查听觉,视觉和跨模式
加工。具体目标2是直接测试跨模式下的注意机制的能力
处理以说明听觉输入对提取统计结构能力的影响
从视觉输入。实验将由我们的假设指导,即注意机制
基础跨模式处理可以说明高阶认知任务的性能,
需要处理视觉结构,例如单词学习,类别学习和学习
多个意外事件。每项研究都将包括8个,12个月和16个月的多个实验
婴儿,将包括各种方法。拟议的研究很重要
因为它将产生新知识,影响我们对发展的理解
注意及其在跨模式加工中的作用,从而揭示了早期的一些基本机制
词汇和认知发展。这些知识也可能对临床产生更大的影响
通过阐明特定语言障碍(SLI)的基本因素的社区。
