我们采用事件相关脑电位（ERPs）和信号检测的措施，以比较注意周围和中央视觉刺激的听力正常的受试者谁出生的聋人父母（HD Ss），其第一语言是美国手语（ASL）。并与听力正常的Ss42和先天性耳聋的Ss43在同一范式下的结果进行了比较。3组在注意中央凹区域期间的任务表现和ERPs相似。与此相反，注意到周边刺激的聋人Ss显示的注意力的影响，在枕区的两个半球是几倍大于听力和HD Ss。然而，无论是HD和聋人的SS显示的行为和ERP的方向相反的听力SS的横向不对称。听力正常的Ss在目标运动发生在左视野时能更好地检测目标运动的方向，而听力正常的Ss在右视野目标时表现更好。与这些结果相一致的是，注意相关的增加幅度的ERPs是从颞叶和顶叶区域的右半球比左半球的听力Ss，但从左半球比右半球的HD和聋人Ss。这些结果表明，听觉剥夺和视觉语言的习得对人类皮层特化的发展有显著的和不同的影响。
We employed event-related brain potentials (ERPs) and measures of signal detectability to compare attention to peripheral and central visual stimuli in normal hearing subjects who were born to deaf parents (HD Ss) and whose first language was American Sign Language (ASL). The results were compared with those obtained from normal hearing Ss42 and congenitally deaf Ss43 in the same paradigm. Task performance and ERPs during attention to the foveal region were similar in the 3 groups. In contrast, with attention to the peripheral stimuli the deaf Ss displayed attention effects over the occipital regions of both hemispheres that were several times larger than those in the hearing and the HD Ss. However, both HD and deaf Ss displayed lateral asymmetries in behavior and ERPs that were opposite in direction to those of the hearing Ss. Whereas hearing Ss detected the direction of target motion better when it occurred in the left visual field, deaf and HD Ss performed better for right visual field targets. Consistent with these results, the amplitude of the attention-related increases in the ERPs were larger from temporal and parietal regions of the right than the left hemisphere in hearing Ss, but were larger from the left than the right hemisphere in both the HD and the deaf Ss. These results suggest that auditory deprivation and the acquistion of a visual language have marked and different effects on the development of cortical specializations in humans.
