The Seaforth News, 1957-04-25, Page 2Too Much Money Made Chimps Bums Even in his early days at San Diego zoo it was obvious that the chimpanzee, Trader, had better developed business in-, .tincts than most chimps. He was always searching his cage for odd bits of wood or other material which he would then Offer to anyone who was stand - !ng around. It was his way of shopping, for he expected some tit -bit in return. And he got it. So much so that he went in continual danger of overeating. But Trader's stay at San Diego did not last for very long. One day a psychologist happened to Visit the zoo, and was most in- trigued by his behaviour. Be began to wonder h o w liar Trader's business faculties might be developed, and hepersuaded the authorities to sell • him. At-home he set about systema- tic training. The first thing to do was to develop a sense of money — the idea that only cer- tain things could be used to buy food — and for this the psycho- logist chose poker chips. Trader soon got the idea. Whenever he wanted anything he fetched a poker chip from a box at one end of the room, He handed this over and was at once given his reward. Could Trader master the use of coins of different value? The single box of mixed poker chips was replaced by four boxes, each containing chips of .a dif- ferent colour. Whenever he fetched a red chip and paid it Ln he was given a piece of erange.A slice of banana cost a white chip, and a piece of bread a green one. In a matter of a few weeks Trader had mastered this simple , monetary system, and certainly used it to the best advantage. At Yale University Dr. Wolfe has carried similar experiments with half a dozen chimpanzees a haod deal further. The animals ve learned to use a slot ma- chine and also to work Tor their ships. A special slot machine was devised that would deliver a grape each time a chip was Inserted. Small brass counters were also supplied, and although they would go into the slot, they did not produce a grape. After a very few lessons all .ix chimpanzees had not only Learned to put chips and coun- ters into the slot machine, but were already discarding the GIRL CRAZY? — Trying to get u woman off his mind seems a lough job for this nightmarish figure in a surrealistic oil paint- ing exhibited in Antwerp, Bel - plum, by Dutch painter Johan Koopmans. He calls it "Life Without Issue" and says It por- trays a couple tired of each Other but hopelessly bound. brass counters as they realized that ,:these • gave them no re- ward. From then on whenever a mixed handful, of. chips and counters was thrown down onto. the floor there was an -unseemly scramble for the chips, and much snatching from one another. But the counters were completely ignored. Dr. Wolfe's next' -aim was to see how farchimpanzees could• learn to work for a reward, and for this he constructed a work machine. This consisted of a handle requiring an 18 lb. force to.move it. When it, was lifted to its maximum extent, .a grape was revealed and could be picked out, This happened every time the handle was lifted, so that the total rewardwas proportional to the amount of work done. The idea was mastered in two or three day. • The chimps had now learned the value of money, and they had also got the idea of work- ing for a direct reward. Were they capable of learning to work, not for grapes, but for money that could be then used to buy grapes? To find this out Dr. Wolfe modified his :work machine so that when the handle was lift- ed a poker chip appeared in- stead of a grape. The slot ma- chine from which grapes could then be bought was standing in another part of the room. Sure enough all six of them soon gat the hang of this, and there was much rushing to and fro' between work machine and slot machine. New came the stiffest test of all, designed to bring the chimps more into line with the wroking man, who does his work for money which he will not spend immediately but some time later. First of all the work machine was made available on its own, the slot ma- chine only being brought in an hour later. This delay was grad- ually extended until chips work- ed for one day could not be spent until the next. Once again the chimps under- stood, but the interesting thing this time was that different in- dividuals showed different re- actions. There were the thrifty ones, who were quite content to work hard and save their money until the opportunity arose to spend it. Others, though, obviously corresponded to the human spendthrift. They were most reluctant to work un- less they could claim, an im- mediate reward, and conse- quently usually had very little money behind them when the slot machine appeared. Does security make people less willing to work to the best of their ability? Hard to say, but it seemed to be the case with the chimps, even the more thrifty ones. If he was broke when the work machine arrived, the most energetic member of the party usually worked very hard, lifting the -handle at least 100 times. But if he was given thirty chips to start with he would only bother to work for about a :dozen more. Money often brings out the worst in man, and it seems to have had a similar effect on some of the chimps. With in- creased money came moral de- gradation. Some attempted to monopolize the work machine and amass for -times they could not hope to spend, and although they would not think of shatch- ing food from each other, they would stop at nothing in their efforts to rob one another of chips. Husbands would approp- riate the whole of their wives' earnings, reluctantly returning the odd chip when they protest- ed! TASTE FOR ART—Unlike the Baltimore zoo's famed finger-paint- ing chimp Betsy, the Cincinnati zoo's chimpanzee,' proved a Complete bust as an artist. He ate the art stuff up but only literally. In a session with finger paints and canvas he produced no salable paintings—just gooey smears. Then he proceeded to 'm his own worst critic and started chewing up the canvas. Unique .Plastic Heart Valve Saves a Life A few weeks ago Ruth Brown was totally crippled, Though only 22 she could not breathe • Tying down, her .blood pressure and heart beat were almost out of control. The slightest exer- tion caused her heart to fail. Her heart pumped blood into an artery but it ran right back into the heart because a valve was not functioning properly. But advanced medical science has given her life back to her. A man-made plastic valve, right, now controls the blood from, her heart. It Wai inserted by a skilled team of surgeons at St. Mary. Hospital using a delicate technique first reported in 1954. A newly developed heart pump is used to detour the circulatory system while the valve is inserted. TABLE TALKS Jam AtuiDews.

Vessels of Hope It is a happy coincidence that the good ships Susan Constant, Discovery and Godspeed, should arrive in. Washington on the first day of spring, a time of hope and renewal. Nominally, the journey from England of the pint-sized craft commemorates the 350th anniversary of the arrival of America's first colon- ists at Jamestown. But it is, more than that. The graceful replicas also serve as a vivid reminder that this land was settled by men who dared to sail an uncharted sea to an unknown destination in vessels little bigger than a lifeboat on a modern ocean liner. Visitors will be able to inspect the flagship, Susan Constant. A tour of the ship should give a first-hand savor of the great age of adventure and discovery in which the seeds of American democracy were first planted on Virginia's shores. The . pilgrim- age of the three wonderfully named ships acts as a salty tonic in a time when anxiety and timidity blind many of us to the new horizons of adventure open- ed by the atomic age.—Washing- ton Post and Times Herald. Just How To Catch a Trout. "I have 200 bucks worth of trent tackle, including rods that ' bend like the neck of a swan and 'lures' guaranteed to tickle the fancy of any squaretail in the lake; I have yakked to tac- kle salesmen behind dozens Of counters and'I have batted the breeze for nights on end with trout anglers in every fisher- men's bar for -500 miles --but 1 can't catch a trout!" This annual tale of woe is as common a' complaint with the growing army of novice anglers as fallen arches. It just isn't possible to solve. this anguishing problem entire- ly In a few paltry paragraphs; if every new trout fisherman Would follow a few common- sense rules there'd be far fewer wails of woe and a lot more fish in their brand-new creels: 1. Pick at first, a small brook known to have trout. It need Only be a couple of feet wide winding calmly through a mea- dow. 2. Sneak up on the stream with soft footfalls and never let your head come within the vi- sion of a potential fish. 3. Step as far from the bank as possible and gently drop in the lure -such ' as a worm, a small minnow or one of those little gold spinners. Move the lure carefully, still keeping out of sight ,of the fish. Let it sink and jerk it slowly to the sur- face. Do this several times. ' If unproductive, move quietly t0 another spot. Keep doing this with infinite patience. You are bound to catch a trout. Once you take a fish, you will understand that they can be taken if they are not in the least alarmed and usually only then. 4. Once you have learned the initial lesson, go with confidence to a larger water and, watching how others do it, even attempt the use of flies. If you want to use a dry fly, sneak up on a little hole and drop it gently at the end of a four -foot line on the surface near the bank. Soon you will understand how trout rise to a dry fly and then you can go on to master the art of castingin your own back yard. 5. To fish in big and heavily fished eastern streams note care- fully the hours, methods and spots used by local fishermen. Then act accordingly. 6. Never invade the fishing territory being used at the mo- ment by another . angler and under no circumstances ever tramp heavily around in the water. This is like stalking deer with a dinner bell—and other anglers never;,: orgive you. 7. Don't worry if early -season cold -water angling is unprO- ductive. The colder the water, the less the trout feeds. You should begin to es 4 reaction by around May 30 northern waters. • The angler • must remember that trout are like people. They normally eat only at certain times' or when a free breadline (like a sudden hatch of insects) becomes available. The rising and :waning light Of dawn and evening usually are the most productive but really large trout often feed only in the black of night. To catch a six -pound brown trout . for example keep visiting a: good stream until you deter- mine where one habitually feeds. You can often hear him splash at night at the side of a big pool. Once located, wait`" for a moonless night, wade carefully in position and cast a big black fly, retrieving it in slow jerks after it has sunk to. the bottom. Do this until your arm is ready to drop off. Maybe sooner than you expect, you'll be fast to him. For some curious reason, there are few night fishermen working the streams today. A few states do not permit night angling far ;:tiibut, . and certain waters are •"taboo in other re- gions. So be sure to consult local laws. ' But, by and large, most Amer. lean trout waters are open tel the nocturnal trout angler, and these days they're the one most likely to take` really large trout —rainbows, browns and brooks, One further word of caution about this night -fishing busi- ness; make certain you have test -waded your locations dur- ing daylight so that you can avoid deep holes. The use of a flashlight—or even a match at night usually puts a big feeding fish down for hours. But remember—sneak up on 'em, keep out of sight, avoid vibration, present the lure na- turally and without fuss or fan- fare and don't try to handle, at first, a long line. _ By Clayt Seegers in The Police Gazette.
