Abstract
Details of research in which Russ Harter participated in his formative years are reviewed. Harter's participation in the early work on Visual Selective Attention (Eason, Harter & White, 1969) probably contributed most importantly to his career. While reviewing Russ's early experience with basic vision research and pioneer visual evoked potentials (VEPs), there is reference to extensive information regarding stimulus effects on VEPs (exogenous components of the ERP). There can be complex early and late waveforms and waveform changes with changes in certain stimulus conditions. There are critical peripheral vision effects at various loci over the visual field on VEP and reaction time. Special emphasis is given to effects of individual differences in training and skill of experienced subjects, as well differences in ability. These observations may suggest methods for optimizing sensitivity of ERPs and possibly some clues toward further understanding of ERPs.
