Getting the point: electrophysiological correlates of protodeclarative pointing.
Full Abstract
We examined the longitudinal relationships between power data in two bands (i.e. 4-6 and 6-9Hz) 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A Preliminary Manual for the Abridged Early Social Communication Scales, 1996, unpublished manual] (n=27).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.
