Visual Mismatch Negativity

摘要

The visual homolog of the (auditory) mismatch negativity, the vMMN, has already been reviewed (Pazo-Alvarez, Cadaveira, & Amenedo, 2003), but a considerable body of more recent research exists. The present paper concentrates on two crucial issues of vMMN research. These issues are the memory-dependence of the vMMN and the problem of attentive vs. nonattentive processing in vMMN research. While both issues require further clarification, vMMN seems to be a promising index of the nonattentional registration of the violation of environmental rules in the visual word.
