摘要：Members of 7 B-29 crews received PME (experimental = 51) or a placebo (controls = 49) and took a group of psychological tests measuring manifest irritability, anxiety, and fatigue reactions, after a long (15-18 hours) over-water training mission. The tests were administered both before the drug administration (immediately upon landing) and after unloading the planes (which followed drug administration). Although there were significant pre-test and post-test differences for each group, there we...

摘要：To improve the efficiency of selection techniques, a method is proposed in which individuals whose criterion score predictability[long dash]as measured by the difference between their standard test scores and standard criterion scores[long dash]is high, are screened first on a measure (such as an occupational inventory) that correlates with this difference, and then those so screened are further screened on the basis of their test scores. An example based on data for two samples of taxicab dri...

摘要：To study the effect of interval length and pointer clearance on the speed and accuracy of interpolating to tenths of a scale interval, 10 Ss each reported readings for nine pointer positions for 36 combinations of scale interval length (0.25 to 2.0 inches) and pointer clearance (0.0 to 2.0 inches). Reading time and errors of interpolation decreased significantly as interval length increased from 0.25 to 1.5 inches, and clearance decreased from 2.0 to 0.125 inches.

摘要：To develop a disguised but objective personality inventory, a factor analysis was performed on scores based on 400 examinees tendencies to accept or reject 13 lists of proverbs constructed to cover 13 areas. The three test factors which emerged ... were: Conventional Mores, Hostility, and Fear of Failure. Using 200 new examinees, scales were constructed by item analysis to measure each. In subsequent samples, the three scales were found to have corrected split-half reliabilities ranging from ....

摘要：Mean Kuder Preference Record Scores were compared for 55 trade-school dropouts and 48 students who completed their programs. The average profiles of the two groups were about the same, and only one mean difference was significant, and that only at the .05 level. It is concluded that 1. The present use of the Kuder Preference Record in these trade training departments of this vocational school is of very limited value in helping students evaluate their decisions to become mechanics . . . [and] ...
