摘要：To determine the effect of encouragement on the individual test performance of Ss with varying amounts of anxiety, two anxiety scales were first administered to a sample of college students . . . three groups of Ss were selected and designated low-, medium-, and high-anxiety. To each S was individually administered the MacQuarrie Test for Mechanical Ability. ... On the basis of scores on this test, each anxiety category was divided into two equated groups. Six weeks later the test was again in...

摘要：8 comparable groups of subjects were each exposed to 3 mythological stories, in one of the following conditions: by audition (tape recording); by reading through once; by read-studying, for the time taken for the auditory presentation; by audition concurrent with reading. True-false post-tests were administered after the material was presented. A single read-through was as effective as auditory presentation; both were slightly inferior to read-study or reading accompanied by the auditory prese...

摘要：A table is given showing the size of [SIGMA]f obs required for significance at the .05 and .01 levels for from 20 to 100 observations in steps of 10, for chi-square analyses including from 3 to 10 cells.

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：Using as criteria ranking of the students on academic performance by 3 faculty judges, and of those who subsequently graduated on field performance, the validity of the SVIB, MMPI, Concept Mastery Test, and the American Public Health Association Examination for selecting graduate students for a public health education curriculum was studied. Only the APHA Examination, an achievement test, ranked the students in approximate order of later success, although the others gave evidence of usefulness...

摘要：The development of the Activity Experience Inventory, a measure of manifest interest (interest expressed by actual participation in relevant activity) is described. The items were scored using the interest areas of the Kuder Preference Record, Form BB. Validity coefficients (against an Experience Data Blank) varied from .27 to .82, median .39. Experience patterns for boys and girls differed in the expected directions. Reliability coefficients are reported. Tentative norms, separate for males a...

摘要：The self-perceived role of first-line supervisors was compared with the role perceived by their superiors. 18 items (word pairs) differentiated between the high and low groups at the 5% level or better. The most outstanding self-perception of the poor supervisor is his sales approach to human relations...[while]...the good supervisor...sees himself as respecting the rights and dignity of others. Conclusions are explored on the basis of the assumptions that (1) the self-perceptions are in appro...

摘要：An empirical study is reported comparing biserial r and triserial r for 100 samples from each of three populations (product-moment r''s of .28, .66, and .91). The empirical standard deviations of triserial r were consistently lower than the standard errors of biserial r. Furthermore, ...the simple formula can be safely used when the high and low groups do not differ by more than .10..

摘要：For a two-celled chi-square where d is the discrepancy between the observed and expected frequency, X2 is the value of chi-square at the required level of confidence for 1 d.f., and N is the number of cases, the relationship is graphed for X2 at the .01 and .05 levels of confidence. From the graph, the size of d may be compared with N to determine whether the discrepancy exceeds chance expectancy at or beyond these levels of confidence.
