Abstract:I T HAS been noted by Peoples and Guttmann, ' Myerson," Nathanson" and others that benzedrine has a stimulating effect psychologically. A feeling of exhilaration and a sense of increased energy and capacity for work were noted in adults. Sargant and Blackburn! investigated the effects of benzedrine on 48 adult patients in a mental hospital, using Cattell's intelligence tests, and noted an 8% improvement in the test scores. The unpleasant reactions were infrequent in adults and no serious toxic effects were … Show more
“…Amphetamine sulfate has been observed to reduce the hyperactivity of certain behavior problem children (2), to bring about an irnprovement in schoolroom adjustment and academic performance in some pupils (3), and to have a favorable effect upon nocturnal enuresis (4). Although some observers noted that the drug has stimulated children to increase their psychometric test scores (5,6), it apparently does this only insofar as it increases the child's confidence and energy in attacking his intellectual task (7).…”

“…Improved school performance in problem children has been reported for the duration of administration of this drug (23). Some experimenters have found an increase in intelligence test scores in their benzedrine groups as compared with control subjects (32,33,39), but in no case has it been demonstrated that the obtained differences are statistically significant. Other experiments have failed to show any favorable effect of the drug on intelligence test scores (18,24).…”
“…McNamara and Miller (8), using smaller dosages, discovered no effect upon three digit multiplication. Molitch and Eccles (p) found the drug produced higher scores on retests with intelligence tests and Molitch and Sullivan (10) noted that it produced higher scores on retests with the new Stanford achievement tests.…”
The data of this investigation warrant the following conclusions: "(1) Fifteen m.g. of benzedrine sulphate has no effect on (a) number of blocks occurring in color naming, (b) length of blocks, (c) location of blocks within trials, (d) influence of fatigue on length of blocks, and (e) influence of fatigue on speed of response. (2) Fifteen m.g. of benzedrine sulphate slightly increases speed of response in color naming. (3) Most of the variation in blocking and speed of response is due to individual differences."
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
