Abstract
Seriatim cold-mapping with a range of five stimulator sizes, the smallest 1 mm diam., gives satisfactory reliability coefficients (.80 or over) with all sizes in the majority of untrained subjects. Avg. scores indicate roughly a linear summation effect at the lowest levels, but the curve flattens out rapidly with the larger sizes. Even with the 1 mm diam. stimulator, the maps tend to show grouping of similar scores into hills and valleys, and not a random arrangement of separate cold spots. By mapping the same area with 2 different sizes of stimulator, it should be possible to attack the problem of summation with supra-liminal stimuli.
