我们检查了在14个月时大脑中电活动的两个频带（即4-6和6-9 Hz）中的功率数据之间的纵向关系，如通过背景脑电图（EEG）所测量的，其中在18个月时具有原始陈述和原始命令指向，如通过早期社会交流量表（ESCS）所测量的，[Mundy et al.，ESCS：A Preliminary Manual for the Abridged Early Social Communication Scales，1996，unpublished manual]（n = 27）.脑电图记录从64个传感器使用电气测地线（EGI）系统的密集阵列传感器网络。多变量排列测试（MPT），控制了实验错误，由于多个显着性检验，发现在额叶区的对数转换功率在14个月和protodeclarative之间的显着相关性，但不是protoimperative，指向18个月。(C)2002年ISDN。由Elsevier Science Ltd.出版，版权所有。
We examined the longitudinal relationships between power data in two bands (i.e. 4-6 and 6-9 Hz) of electrical activity in the brain at 14 months, as measured by background electroencephalograms (EEG), with protodeclarative and protoimperative pointing at 18 months, as measured by the Early Social Communication Scales (ESCS), [Mundy et al., ESCS: A Preliminary Manual for the Abridged Early Social Communication Scales, 1996, unpublished manual] (n = 27). EEGs were recorded from 64 sensors using the Electrical Geodesics (EGI) system's dense array sensor nets. Multivariate permutation testing (MPT), which controlled for experiment-wise error due to multiple significance tests, revealed significant correlations between log-transformed power in the frontal region at 14 months and protodeclarative, but not protoimperative, pointing at 18 months.
