通过三个实验，研究了大脑半球专门化对小模式的快速枚举和计数的影响。实验包括用视动镜技术或通过眼镜监测眼球运动，对一个视野内呈现的点图案进行数量识别，并比较中心呈现的点图案和侧边视动镜呈现的手指。我们的实验表明，在分词范围内的识别和比较任务中，左视野具有优势，而在计数范围内的比较任务中，右视野具有优势。
Three experiments were carried out to study hemispheric specialization for subitizing (the rapid enumeration of small patterns) and counting (the serial quantification process based on some formal principles). The experiments consist of numerosity identification of dot patterns presented in one visual field, with a tachistoscopic technique, or eye movements monitored through glasses, and comparison between centrally presented dot patterns and lateralized tachistoscopically presented digits. Our experiments show left visual field advantage in the identification and comparison tasks in the subitizing range, whereas right visual field advantage has been found in the comparison task for the counting range.
