Pseudo-chromesthesia

The helpfulness of pseudo-chromesthesia is less obvious, yet it is reported in about one-fourth our cases. ' ' Colors do not look right," one subject writes, " unless a word is spelled right. For instance, I spelled permanent, the other day, with two a’s, and it did not look pale enough." Another is helped in writing rhymes, and a third in committing music to memory.

In The American Journal of Psychology for October, 1892, Dr. William O. Krohn treats of the curious phenomena of pseudo-chromesthesia, in which sound gives rise to colo sensation, and he explains it by the nearness of the auditory and visual centers in the brain cortex.
