In a paper published in the 10:4 issue of JOCN, Heinze et al. 1998) studied a directed attention task using hierarchically organized letter Navon stimuli. On the basis of negative PET and ERP findings, they argue that``early sensory inputs are not modulated to gate global vs. local visual information differentially into the two hemispheres .'' Rather, based on positive ERP findings (an N2 effect) in a divided-attention task, they argue that``later stages of cortical processing may be… CONTINUE READING
