We have attempted to correlate the neuropsychiatric observations with our psychological investigations concerning emotional impairment with diencephalic lesions. The implications of the complete absence of color response to the Rorschach, in our 9 cases, were discussed in an attempt to lend further insight into the empirically long-established relation of color to affect.Thanks are extended to Dr. George E. Reed, Medical Superintendent, for his cooperation and kind permission to publish this paper.Abstract Teaser
