中文摘要
一项研究计划概述处理半球专业化在
语言和认知的界面。 提出了一种收敛方法
结合三个实验群体和三种广泛类型的
实验范例 这些科目包括(i)连合切开术
(裂脑)患者,(ii)半球损伤患者和(iii)正常
儿童和成人。 这些技术包括(i)连续观察
复杂的偏侧视觉刺激,(ii)代谢,血流和磁
大脑激活的真实的时间指数,(iii)更传统的范例
半场速示、两耳分听和双任务干扰。
半球专业化的互补模式得到发展,
并应用于正常大脑。 一组
半场决策和促进实验说明了“直接
访问”模型;第二组双耳分听实验说明
“胼胝体中继”模型;第三组研究类型,发展和
调节大脑半球间的相互作用。 第四组实验
继续分析词汇表征的半球差异

英文摘要
A research program is outlined dealing with hemispheric specialization at
the interface of language and cognition. A convergent approach is proposed
combining three experimental populations and three broad types of
experimental paradigms. The subjects include (i) commissurotomy
(split-brain) patients, (ii) hemisphere-damaged patients and, (iii) normal
children and adults. The techniques include (i) continuous viewing of
complex lateralized visual stimuli, (ii) metabolic, blood flow and magnetic
real time indices of cerebral activation, (iii) more traditional paradigms
of hemifield tachistoscopy, dichotic listening and dual task interference.
Complementary models of hemispheric specialization are developed, motivated
by the clinical populations and applied to the normal brain. One set of
hemifield decision and facilitation experiments illustrates the "direct
access" model; a second set of dichotic listening experiments illustrates
the "callosal relay" model; and a third set studies types, development and
modulation of interhemispheric interaction. A fourth set of experiments
continues the analysis of hemispheric differences in lexical representation
and organization, and compares hemispheric specialization for early,
preattentive stages of information processing with specialization for
later, conscious processes. The fifth set completes the comparison between
hemispheric specialization in the three experimental populations for more
complex linguistic and nonlinguistic abilities whose model theoretical
status remains to be determined.
