Many J.P.L. experiments seem unspectacular. One lab is studying the behavior of solid fuels that will burn at the low pressure that rockets encounter at the outer fringes of the atmosphere. A huddle of men in blue smocks stare at a mirror next to a thick window set in a concrete wall. Reflected in the mirror is a 2-ft. object like an outsized bug bomb. For a few noisy seconds, a blue flame spurts out of the bomb, then turns to a wavering trail of smoke. "It chuffed," says one of the men glumly. "That...
Another study was made by Richard E. Thompson '52, which he submitted as his Senior Honors thesis in the Department of Social Relations. Thompson established the SPT as a valid instrument for distinguishing among children already showing behavioral difficulties, those who are true delinquents from those whose maladapted behavior is temporary. The SPT showed that among a representative group of 100 boys, included originally in a research project called the Cambridge-Somerville Youth Study, it would again have been possible to identify accurately 91 per cent of all the boys as either potential delinquents or as non-delinquents...
Another test of the SPT's validity was made in 1954, when the Douglas A. Thom Clinic for Children in Boston, applied it to 57 boys ranging in age from 6 to 12 years, who had been treated for aggressive, destructive, anti-social behavior. The scorings made by the clinic psychologist indicated that 823 per cent of these boys, at the age of six, would have been clearly identified by the test as potential offenders...
...actual behavior of juveniles corresponded with the predicted behavior 91 per cent of the time in follow-up studies involving nearly 2000 cases. Adult male and female behavior has not yet been checked as extensively with the Glueck tables, but so far their accuracy in those two divisions appears to be confirmed as well...
...behavior of juveniles, for example, is more substantially influenced by family life than by surrounding neighborhoods. An unhappy or separated family is therefore a danger sign, as is early anti-social behavior or a poor school record...
