Stimulus Variables in Auditory Projective Testing

BOOK REVIEWS
ments were made of the total refraction and six determining components. The determina tion of uniovularity was established by physi cal characteristics, finger printing, the tasting test with phenylthiourea and blood grouping. For most measurements concordance was found in 80 percent of the uniovular twins and in 40 percent of the binovular twins and controls. Uniovular twins with high ametropia showed intrapair similarity in the op tical components though the incidence of concordance was somewhat less than in the low degrees of ametropia. Concordance was a significant feature of the uniovular series, and the slight discordances found could be reasonably attributed to variation in the ex pression of the genes, but in not a single in stance was there concordance for all six components in binovular twins or the control pairs. The conclusion is therefore warranted that all refraction states and the components thereof are genetically determined. James E. Lebensohn. OPHTHALMOLOGY. By Daniel Vaughan, Robert Cook and Taylor Asbury. Los Altos, California, Lange Medi cal Publications, 1962, edition 3. 340 pages. Price: $5.50. This is a simply printed, soft-bound text book free from frills. However, there has been no skimping on the contents which are readable, well illustrated, well organized and up to date. HQW popular the book has been during its life is attested by the appearance of a third edition since 1958. For the costconscious medical student, here is an oppor tunity to get a lot of book at a noninflated price. Unusual these days. Thomas H. F. Chalkley. GENERAL
STIMULUS VARIABLES IN AUDITORY PRO
By Harvey J. Kramer, Ph.D. New York, American Foundation for the Blind, 1962. 81 pages, bibliogra phy, paperbound. Prices: $1.00. This monograph, based on a doctoral dis sertation in psychology at the University of TECTIVE TESTING.
Rochester, is an expansion of an earlier study subsidized by the American Founda tion for the Blind. In the familiar Rorschach tests personality factors are revealed by re sponses to ambiguous visual stimuli. Kramer secures similar information with ambiguous auditory stimuli. This approach has the ad vantage of being equally useful with both blind and sighted; and is significant espe cially for studying the personality of blind persons. The recorded material is classified as of low, intermediate or high ambiguity. Typical examples are: music and sobs of woman and man; gurgling water; drums and hoofbeats ; screeching brakes and train bell ; breaking wood and ripping cloth ; clock striking and crowd noises; alarm, siren, shots; cat meowing and dog barking; and dialogues of varying obscurity. James E. Lebensohn. T H E MECHANISM OF ACTION OF WATERSOLUBLE VITAMINS. Edited by A. V. S. DeReuck and M. O'Connor. Boston, Lit tle, Brown & Co., 1961. 120 pages, 34 illustrations, index. Price: $2.50. This symposium on water-soluble vitamins honors Prof. Lynen of Munich who discov ered the sulfhydril group in coenzyme A just 10 years ago. The scientists at this Ciba Foundation Study Group include 12 from Great Britain, four from Germany, three from United States and one from Sweden. The articles centered on the intricate mech anisms involved in hydrogen transfer and other coenzyme functions. Nature is amaz ing—the tetrapyrrol compounds can be modi fied by proteins for manifold functions, as in cytochromes a or c, or in peroxidases and catalases. But Nature has not yet reached the acme of perfection—some pyridinelinked enzymes work better and faster with artificial coenzyme analogues than with their natural coenzymes. Chemistry, physics and biology—as this volume reveals—are in the process of fusing into one common natural science. James E. Lebensohn.
