Selective attention, cortical evoked responses, and brain function in human subjects: a critical review and theory.

A theoretical framework is proposed to account for the facts of selective attention in terms of cortical redundancy and cortical-subcortical interactions as measured by the Average Evoked Response and the background EEG. The recent research concerning AER correlations of selective attention is reviewed and found to be lacking in methodological coherence. This lack is found to contaminate existing theory regarding selective attention and brain function. An alternative approach is explored and its findings are found to yield the present theory.
