TUESDAY, MARCH 24, 1953 I 'U' EXPERIMENTS ON RODENTS: Tests Show Gamblers, Rats Similar By FRAN SHELDON 4 s . * * , Although there is little basis for the belief that gamblers are all rats, psychological tests being car- ried on in a University laboratory indicate fundamentally the two may have a lot in common. Prof. Edward L. Walker of the psychology department, in a study of alternation phenomena in the four-footed rodents has been able to draw an analogy between the action of rats when placed in a planned situation and the action of gamblers in a "tight spot." * * * BY PLACING the animals in the foot of a T-shaped run, and providing some stimulus to start them running, Walker has demon- strated the animals, for no ap- parent reason, will tend to run on a second trial in the opposite direc- tion from the one they took on the first. This. tendency, he explained, is due to the inevitable effect the first trial has on the "attitude" of the animal toward the second. If it had no effect on the animal at all there would be equal chance he would run in either direction. This has been disproved in prac- tice, and it has been further dem- onstrated the action of most rats falls into the same set pattern, he said. TAKEN OUT of its setting, Wal- ker showed how this tendency to alternate is analogous to the little publicized gamblers' fallacy, upon which all the better gambling es- tablishments depend for their pro- fits. This fallacy, he explained, causes gamblers to be misled by sequence. For example, a gamb- ler betting on the fall of a coin knows on the first throw there Coif Selects Law School Members The.-following persons, by virtue of the excellence of their Law School records, have been elected members of the Order of the Coif: William A. Bain, Jr., William E. Beringer, R. O. Blatti, Alfred W. Blumrosen, F. M. Bowen, Jr., George V. Burbach, James W. Cal- lison, William K. Davenport, Wal- ter G. Flickinger, Charles R. Gib- son, F. D. Goldstein, Lois H. Ham- bro, John B. Houck, Robert A. Howes, Richard P. Matsch. The list continues with: George D. Miller, Jr., S. A. Newblatt, Dun- can L. Noble, Barbara A. Petrie, Thomas A. Roach, Richard D. Rohr, Marcus A. Rowden, D., W. Rowlinson, Robert G. Russell, John S. Slavens, John F. Spindler, Arthur L. Stashower, James S. Taylor. COIF, the Law School honorary comparable to Phi Beta Kappa, can trace its history back farther than the legal system as we know it today. The present order originated with the English order of the Coif. Consisting of a small number of lawyers, Coif was kept up by a system of apprenticeship corres- ponding to present day legal training. It was from these ranksj new members were selected. THE AMERICAN Order of the! Coif is the outgrowth of an earlier society, Theta Kappa Nu. In addition to a single honor-j ary membership granted to some person who has attained distinc- tion in the legal profession, an- nual membership is restricted to the top ten percent of each grad- uating class. Originally all members were re-j quired to wear a tight fitting cap called a coif. This coif was the ba- sis for the society's name. The cap itself, however, became cumber- some with the advent of legal wigs, and an engraved key has taken its place as the insignia of membership.I RELATES TO MAN'S AFFAIRS: Human Biology Institute Studies Heredity in Mice By PHYLLIS WILLAR A large-eared, hearty, brown genus of mice has been the subject of many years of research which is now being carried on at the In- stitute of Human Biology, situated in the back of a courtyard on East Catherine St. The genus, Peromyscus, has figured largely in the experiments on the heredity of racial charac- teristics which Prof. Lee R. Dice. director of the Institute, has been carrying on since 1925. He began his studies in the Laboratory of Mammalian Genetics which ex- panded into what has been the Institute of Human Biology for three years. THE INSTITUTE now includes the Heredity Clinic, the Biogeog- raphy Section, the Community Dynamics Section, and the Lab- oratory of Vertebrate Biology in which Prof. Dice is studying his native American mice. All the research is combined into as effort to discover fun- damental principles of biology which can be related back to hu- man affairs. The study of the reactions which Peromyscus has to certain experi- ments can lead Prof. Dice and his associates to predict what other animals will do in similar situa- tions. This can then lead to pre- dictions on human habits. IN THE HEREDITY Clinic, re- search is trying to establish what diseases are hereditary, the effects of atomic radiation in producing mutations in man, and the pos- Beetiouen Sonatas Subject of Talk Prof Joseph Brinkman of the School of Music will talk on "The Late Sonatas of Beethoven" at 4:15 p.m. today in Aud. A, Angell Hall. The lecture is sponsored by the School of Music and open to the public. 1 ________ ______ sibilities of inheritance of men- tal diseases. The Biogeography section is di- recting its, investigations primar- ily toward analysing the geograph- ic distribution of reptiles and am- phibians. The idea is to find out information through these two groups about the movement and distribution of other fauna, now extinct. Located in the Museums Building, the Biogeography sec- tion study is being done under the direction of Prof. L. C. Stuart of the zoology department. The Community Dynamics study is concentrating its in- terest in relating natural com- munities of animals to the principles and techniques in- volved in human communities. In addition to the different de- partments of the Institute, sep- arate studies are being carried on, including an assortative mating study and study of heredity abili- ties. The latter study is interested in a possible correlation between mental abilities and physical, traits. Union To Open Secretariat Small campus organizations may, beginning today, take ad- vantage of the Union's typing, mimeographing and postcard mim- eographing facilities under the Union's new secretariat service. Arranging a time and procur- ring stencils for mimeographing may be done by contacting the of- fice manager in the student of- fices.between 3 and 5 p.m. any day during the week. The student offices will be open from 7 to 8 p.m. Tuesdays, Wed- nesdays and Thursdays. The pro- ject will be run at cost and will be handled through the disperse- ment authorization sheet system of the office of Student Affairs. International Jobs Talk Set Summer projects in Interna- tional student relations will be discussed by Barbara Grant, col- lege secretary for the American Friends service committee during a three day stay in Ann Arbor. Miss Grant will arrive in Ann Arbor today and will meet with students at 5 p.m. atthe Congre- gational Guild House. She will re- main in Ann Arbor until Friday. International seminars, student work camps across the United States, and trips to Europe and Japan are planned for this sum- mer. Students wishing to make ar- rangements through the Friends can make appointments to see Miss Grant by calling Lane Hall. Olson Tells Rotary of ParisMeeting Four hundred Rotarians and their wives from southern Michi- gan and western Ontario heard Dean Willard C. Olson of the ed- ucation school report Sunday in the Union on a recent UNESCO conference in Paris, to which he was North American delegate. Willard told the group "broad" education, such as we have in this country and Canada will prevent countries from "stagnating," and indicated that in some European countries, social and economic forces were opposed to "broad" education. Stern To Lecture On Japanese Art "The Traveling Exhibition of Japan's Art Treasures" will be dis- cussed at 8 p.m. tonight in Rack- ham Amphitheater by Harold P.

However, Walker continued, if the coin falls heads up several times in a row the tendency of the gambler is to become more cer- tain it will now fall tails, and bet on this alternative despite the factf that each individual throw still has equal chance to fall either way. * * * ACTUALLY, although the prob- ability of a coin falling the same way ten times in a row is one in a thousand, the possibility of the eleventh try falling the same way is still 50-50, he pointed out. Gamblers (and rats), Walker explained, are affected by the out- come of previous trials until their reasoning is influenced and they have a distorted picture of the circumstances. He said the reasons behind this tendency toward alternation are not as yet completely understood either in the rats or in the gamb- lers, but pointed out considerable use is made of it, and to obvious profit, in gambling establishments where the machines are not "fix- ed."
