Result of analysis of EEG responses of infants between 8-13 months of age to the syllable speech sounds are presented. We conducted an ERP experiment with an oddball paradigm consisting of two types of deviant stimuli (easy and hard) and standard stimulus. A nonnegative Tucker tensor decomposition (NTD) was used to characterize differences in processing of stimuli using a time-frequency-spatial (multi-domain) features. We extracted the multi-domain features for a reliable representation of the underlying infant brain activity to analyze the processing of standard and deviant stimuli. between standard and deviant stimuli and may be interpreted in terms of mismatch negativity (MMN) and acoustic change complex (ACC) evoked potentials. Moreover, these results serve as a proof-of-concept for application of tensor decomposition-based analyses for challenging infant EEG data.
