An investigation of hemispheric specialization and visual event related potentials in discriminations of line length

Brain potentials during mental distance judgments

“…L and M, or M and Polich (1987) has shown nicely that harder tasks generally increase the latency of the late potential and decrease the amplitude compared to easier tasks. A report by Andreassi and Juszczak (1984) involving visual line length discriminations is of interest here, although the experiment was not designed to study distance judgments. Subjects viewed a 1.0 cm vertical line followed 2 s later by lines of either 0.9 cm, 1.0 or 1.1 cm lengths.…”
