项目摘要
DESCRIPTION: (provided by applicant) Facial expressions are complex signals
caused by rapid changes in facial muscular activity that are brief and last
only a few seconds. Humans typically decode these signals during dynamic
interactions in which the face moves. The present proposal aims to fulfill a
gap in the literature regarding a well documented, but poorly explained
phenomenon. Over the years, numerous studies have shown that the left side of
the face is more emotionally expressive than the right. This asymmetry is more
predominant for right- than left-handers and seems to occur for both negative
and positive expressions. Even nonhuman primates such as the rhesus monkey have
been reported to display more intense expressions over the left side of the
face. The basis for these asymmetries is unclear. The most popular
neuropsychological interpretation has been that this left hemi-face asymmetry
is a consequence of a right hemisphere advantage in processing emotional
material. Unfortunately, little progress has been made since the late 1970?s to
more clearly articulate this position or to evaluate alternative explanations
for observations that the left hemi-face is more intensely expressive than the
right.
The overall purpose of the proposed research is to examine three hypotheses
that might contribute to our understanding of hemi-facial movement asymmetries
and assess their viability using contemporary state-of-the-art methodologies.
The specific aims of this project are: (a) to use trans-cranial magnetic
stimulation (TMS) to learn whether the left lower hemi-face receives more
cortical influence (either contra-lateral or ipsilateral) and determine whether
this relates to behavioral asymmetries in dynamic facial expression; (b) to
test the hypothesis of material specific (linguistic, emotion) hemispheric
priming of contra-lateral motor systems; and (c) to test the hypothesis of
lateralized inhibition of contra-lateral motor systems. A series of 6 studies
are planned using cognitive priming, trans-cranial magnetic stimulation, and
computer-based systems for digitizing dynamic facial signals. Either singly, or
in combination, an increased understanding of these hypothesized mechanisms
will likely contribute to our knowledge of expressive asymmetries and provide
information that will ultimately be useful for examining emotional
communication disturbances associated with psychiatric and neurologic disease
in humans.
描述:(申请人提供)面部表情是复杂的信号
由面部肌肉活动的快速变化引起的,这些变化是短暂和持久的
只有几秒钟。人类通常在动态过程中对这些信号进行解码
脸部运动时的相互作用。目前的建议旨在实现
文献中关于一个有充分记录但解释不充分的
现象。多年来,大量研究表明,大脑左侧
这张脸比右边更能表达情感。这种不对称性
主要是右撇子而不是左撇子,似乎两者都是负面的
和积极的表情。即使是非人灵长类动物,如恒河猴,也有
据报道,在大脑的左侧显示出更强烈的表情
脸。这些不对称的基础尚不清楚。最受欢迎的
神经心理学的解释是这种左半脸的不对称
是右脑在处理情绪方面的优势的结果
材料。不幸的是,自上世纪70年代末以来,进展甚微?S
更清楚地阐明这一立场或评估其他解释
因为观察到左半脸比左半脸更有表现力
正确的。
拟议研究的总体目的是检验三个假说。
这可能有助于我们理解半面部运动的不对称性。
并使用当代最先进的方法评估它们的可行性。
该项目的具体目标是:(A)使用经颅磁
刺激(TMS)以了解左下半面是否接收到更多
皮质影响(对侧或同侧),并确定
这与动态面部表情中的行为不对称有关;
检验特定物质(语言、情感)半球的假设
对侧运动系统的启动;以及(C)检验假设
对侧运动系统的偏侧抑制。一系列6项研究
计划使用认知启动、经颅磁刺激和
用于数字化动态面部信号的基于计算机的系统。要么单独,要么
总而言之,对这些假想机制的理解有所增加
将可能有助于我们对表达不对称性的了解,并提供
这些信息最终将有助于检查情绪
与精神和神经疾病相关的沟通障碍
在人类身上。
