SIX THE MICHIGAN DAILY THURSDAY, JANUARY 6,1955 BETTER THAN RATS? Maze Tests Human Learning Ability By GAIL GOLDSTEIN "Get from the beginning to the end In the shortest way p0s- sible" ..i This was the instruction given to students participating in an experiment in which a hutge maze was constructed In the basement of Hill Auditorium. The maze was used to test humans much in the same manner that rats would be tested. For Doctoral Thesis -Directing and supervising the experiment, which was conduct- ed by Joan Morton Kelly for her doctoral thesis, was Prof. Emer- itus John F. Shepard of the psy- chology department. Prof. Shep- ard designed the maze which was used to attempt to determine hu- mans ability in learning to rea- son compared to that of a rat when in a similar situation. The experiments with rats had been already carried out by Prof. Shepard. The first problem was to con- struct a human walk-through maze which would parallel as nearly as possible that used in rat studies. Cheesecloth Thirty-six hundred yards of flame-proof cheesecloth was used to ennstruct the maze. Alleys of the maze were aboute two feet wide and seven feet high. The room was kept completely dark so no direction could be de- termined. The subjects in the ex- periment used lights fastened to their heads with the battery around their waists as they tried to find their way through the maze. Using this method of lighting, the subject couldn't see out of the maze but recorders could keep track of the movement of the subject by observing the light shining through the cloth. Pre-Acquaintanceship To attempt to acquaint the sub- jects with a maze, they first were shown a training maze. Shepard designed three of these training mazes, in which three different types of alleys were included. There Were other problems that the experimenters had to figure Feikens, Hart Party Groups Lieutenant-Governor Philip A. Hart and John Feikens, chairman of the Republican State Central Committee, will be main speakers at the annual Democratic and Re- publican Party Days Monday and Tuesday at the Rackham Bldg. Open to student representatives from Michigan colleges and uni- versities, the event is sponsored by the Mchigan Citiznshi Cering Cng sudns in partsan politics. i Co-pnoso h oiia cratic and Republicn State Cn cans and Young Democrats. "Why I Am a Democrat" will be the theme of the Democratic Par- ty Day Monday while Republican Party Day Tuesday will be cen- tered around youth expressing it- self in politics and government. Programs for both meetings-'will begin at 10 a.m. with a panel of State party leaders discussing the day's theme. Following a luncheon students will split tnto discussion groups moderated by a member of the political science department and attended by a State party leader.

Rats get a quality of stimu- lus from the floor which they are able to use in distinguishing one spot from another. Humans do not have this quality so something comparable to this had to be de- termined. Therefore various non- sense symbols were placed at the junctions of the alleys. Thinking Aloud Results both using these sym- bols and not using them were de- termined by recorders. Subjects were also encouraged to think out loud about all that occurred to them as they traveled through the maze. This was also recorded so that the reasoning method of the human could be determined. The subject was blindfolded be- fore being led into the room con- taining the maze which he had not seen before. After he learned the m'aze he was also allowed to freely explore it to definitely or- ganize it in his mind. He was also put Into the maze at different spots Instead of starting from the beginning to try and find the way to the end. Ratipnal Thinking In this attempt to see whether a human 'learns by a~ rational method and uses a plan and takes advantage of new situations, it was found that more trials and errors were necessary for the non- symbol group to learn the maze. Three levels were able to be determined from the experi- ment. The first of these were the reasoners who were explorers and attempted to find out why they chose the wrong ways through the maze. . The second level of behavior that was determined from these tests consisted of those who didn't learn by pattern. These subjects did not see interrelations and were lost when the maze was ehanged. Relearning In between these two types were those who did take the short cuts but did this by the process of relearning rather than reason- ing. These subjects often got lost when exploring to find short cuts and were not systematic In their learning. They were also reluc- tant to explore and became ster- eotyped on one path without knowing why they took it in pref- erence to the other. Now stored in boxes until an- other experiment is attempted, this first maze experiment was carried out in 1947-49. Subjects for the work were students from Shepard's class in experimental psychology. Undetakn b DA Dirctor By SI SILVER Marionette production is an "adult undertaking." "So we hope for a 'great pro- ponderance of University stud- ents in our first group," comment- ed Richard Trusdell, director of the Dramatic Arts Center's new marionette theater. The first class of 15 will meet once a week for 15 weeks and learn marionette production from the bottom up. The cost of the course will be $15 per person. The first thing the class will have to do, said Trusdell, is to select a play. Marionettes can be used in almost any type of plays except for some modern dramas-. Tey have been used ineverything from Greek tragedies to opera. Sculpture Students After selecting the play the production work will begin. There will be "head and body' modeling for sculpture students, scenic and costume design for artists, wood- work on the settings and the stag- es, illumination problems for the electrical engineering student. Work will also have to be done on costume sewing, learning of parts and music. Marionette pro- duction requires everything that regular play production does, only on a smaller scale. After the production is ready, Trusdell plans to present it at various clubs and schools. He said he hopes that the members of his first class will continue with the Dramatic Arts Center, teach- ing other people the tricks of mar- lonetting. Trusdell graduated from the University in 1939 and is now employed by a local architectural fi. He got started working on marionettes while still in high school.

Admission is Living across the street from the Northwestern campus, he became connected with a marionette group at Northwestern. As a result of shows they were presenting, Trusdell's group was asked by a Chicago department store to give marionette plays for children in the store during the Christmas season. An indirect result of a letter Trusdell wrote to the Chicago Opera Company about a mistake they made resulted in an invita- tion to organize a group to stage marionette operas in nearby com- munities. Opera Stars sgsewhile voices of efamous opera stars were dubbed in. Later he produced marionette shows at the World Fair in Chicago. Trusdell left the marionette world in 1950 and donated his stage and marionettes to North- western and the Detroit Institute of Arts. Visitors To Offer Political Courses Two visiting 'lecturers will offer courses in the political science de- partment during the spring se- mester. Prof. Nidamarulu Srinivasan of indhra University, Waltair, In- dia, will offer a course on the gov- ernment and politics of present- day India. He is the author of -a book entitled, "Democratic Gov- ernment of India," and he' has gritten several articles in pro-. fessional magazines. Prof. Malcom C. Moos of Johns Hopkins University will offer a proseminar in political behavior and a seminar in American politi- cal parties and electoral problems. Prof. Moos has written 'exten- sively on national, state and local government. He has participated in Baltimore politics and local newspaper work. Out-of-State Scholarship Wnhen letters go out tomorrow tor the country, operations will begin on a new program of scholarship aid for future out-of-state stu- dents, sentative of the MVichigan Aum- ni Fund, the Alumni Association and the University Committees on Budget and Scholarship, a $15,000 gift of the Alumni Fund was al- located for out-of-state scholar- ships. Previous financial aid to stu- dents outside Michigan has been considerably smaller than the funds to state residents. To Attract More Students T. Hawley Tapping, General Secretary of the Alumni Associa- tion, yesterday termed the pro- gram a "wonderful thing-an at- tempt to draw students from all over the United States, who could- n't otherwise afford it, to the Uni- versity." According to Assistant to the President Erich A. Walter, the $15,000 fund is established for use next year, and will be divided into 15 etaual scholarships. Each will be given in eight semi-annual in- stallments of $125, and applied to students' tuition costs as long as their renewal is warranted. Names Submiitted Explaining scholarship proce- dures, Walter said names of can- didates for the aid must be sub- mitted by out-of-state alumni or organizations. Candidates, Walter added, must be "admissable to the University with superior high school records and a strong desire for higher edu- cation hprp" Appuczaiuxns tor tne scnoiarsnips are due April 1, with' winners to be announced May 16. Procedure for awarding the sums, Walter emphasized, will be reviewed next fall, in the light of this spring's experience. Act As Incentive "We very much hope," he said, "that some of these scholarships will act as incentives to alumni clubs not now active in scholar- ship programs." Tapping predict- ed, "Alumni should seize on this program as an unusually fine op- portunity." Dean of Women Deborah Bacon, citing various scholarships now given by alumnae groups, called the out-of-state scholarship pro- gram "an effort to pull all the small sparks of alumni enthusiasm into one steady fire." Thomas E. Dickinson, assistant director of the Alumni Fund, said the scholarships will roughly para- llel aid now given to Michigan re- sidents by Regents-Alumni scho- larships. Revelli To Direct SymponyBand Prof. William D. Revelli, direc- tor f Unversty bndswil di- et the first symphony ban con- cert of the year at 8:30 p.m. to- morrow in Hill Auditorium. Included in the program are compositions by Rossini, Johann Sebastian Bach, Dr. Edwin Franko Goldman and John Phillip Sousa. Scheduled at the time of the Tenth Annual Midwestern Confer- ence on School Vocal and Instru- mental Music to be held here to- morrow and Saturday, the concert is open to the general public with- out charge. Nuclear Research at BNL NINE UNIVERSITIES: NIGHT VIEW OF THE COMPLEX BUILDINGS HOUSING THE BROOKHAVEN REACTOR AND ITS SUPPORTING ELEMENTS P EACETIME uses ol atomic en- ergy as well as the effects of radiation are part of the govern- ment's science program. Brookhaven National Labora- tory, Long Island, New York, is one of the regional research cen- ters for fundamental and applied research in the nuclear sciences and related subjects. BNLJ is an integral part of the Atomic Energy Commission's nationwide pro- grm AEC Contract Like the other national jabora- tories, Brookhaven is operated by a private institution under con, tract with the AEC. The Brook- haven contractor is Associated Universities, Inc., consisting of nine Eastern schools: Columbia, Cornell, Harvard, Johns Hopkins, Massachusetts Institute of Tech- nology, Princeton, Universities of Pennsylvania and Rochester, and Yale. The Brookhaven program has four objectives: 1. to seek new knowledge in the nuclear and other related sciences; 2. to en- courage appropriate use of its f a- cilities by qualified scientists of university, industrial and other laboratories, primarily in the Northeast; 3. to assist the AEC in the solution of specific problems; and 4. to aid in the training of scientists and engineers in nuclear science and technology. There are nine general divi- sions or departments at BNL. The Cosmotron enables scientists for the first time to duplicate billion- volt particles found in the outer atmosphere and controlable in the laboratory. Atomic Pile Then there are the accelerator development division and the nu- clear reactor or atomic pile where uranium atoms split In a contin- uous chain reaction. In nuclear engineering, the development and storability of components for fu- ture reactors as well as by-pro- ducts are studied. Physics, chemistry and biology, are additional units. Brookhaven is the first organization to start a hospital devoted primarily to re- search in the field of atomic en- A A HEAVY MACHINE SHOP INSURES TOP PERFORMANCE FROM RESEARCH EQUIPMENT U A ergy.
