PERSONALITY INFLUENCES ON CONFIDENCE TEST SCORES*

From the earliest years in the development of confidence testing, several authors have expressed the concern that confidence test scores were influenced, to a measurable degree, by personality variables. Advocates of confidence testing have claimed that the effects of personality variables can be reduced with practice. This study attempts to evaluate the association of personality variables with confidence test scores in light of practice. It was concluded that although significant correlations between personality variables and confidence testing scores could be obtained, these correlations did not hold up with replication.     

PREDICTION OF WITHIN-SCHOOL SYSTEM VARIANCE IN TEST SCORES FROM WITHIN-COMMUNITY VARIANCE IN SOCIOECONOMIC STATUS 1

Prediction of school systems' scores on cognitive tests from average socioeconomic indices for communities has proved very helpful for several applications. It would also be useful to be able to predict within-school system variance in test scores from within-community variance in socioeconomic status. The present study examined correlations between standard deviations of test scores and an index of within-community variability in income. These correlations were of borderline significance. It was noted that correlations among test standard deviations themselves were quite low, suggesting that within-school system variance is a characteristic of less generality than school systems' median performance in different test areas.     

EFFECTS OF COACHING ON GRE APTITUDE TEST SCORES

Test preparation activities were determined for a large representative sample of Graduate Record Examination (GRE) Aptitude Test takers. About 3% of these examinees had attended formal coaching programs for one or more sections of the test.
After adjusting for differences in the background characteristics of coached and uncoached students, effects on test scores were related to the length and the type of programs offered. The effects on GRE verbal ability scores were not significantly related to the amount of coaching examinees received, and quantitative coaching effects increased slightly but not significantly with additional coaching. Effects on analytical ability scores, on the other hand, were related significantly to the length of coaching programs, through improved performance on two analytical item types, which have since been deleted from the test.
Overall, the data suggest that, when compared with the two highly susceptible item types that have been removed from the GRE Aptitude Test, the test item types in the current version of the test (now called the GRE General Test) appear to show relatively little susceptibility to formal coaching experiences of the kinds considered here.     

EFFECTIVENESS OF HIGH SCHOOL GRADES FOR PREDICTING COLLEGE GRADES OF BLACK STUDENTS: A REVIEW AND DISCUSSION1

The purpose of this study was to reexamine the value of high school grades (relative to standardized test scores) for predicting college grades of black students. Data from previous studies and from a predominantly black university were analyzed. Results tend to indicate that high school grades do not consistently make the greatest contribution in predicting college grades of black students, perhaps particularly of men, whereas they do for whites. Unreliability of grade reporting, invalidity of grades in high school, restriction in range due to selection processes, and intergroup differences in personality characteristics were advanced to explain this phenomenon. Further research on this problem was suggested in view of the fact that many selective institutions are relying heavily on high school grades in their selection of black students.     

INTERACTION OF RACE AND TEST ON READING PERFORMANCE SCORES

This study examines the relationship between race and performance on two nationally standardized reading tests. The appropriate reading tests of the Iowa Test of Basic Skills and Metropolitan Achievement Battery were administered to all fourth and sixth-grade students in all elementary schools of an urban school district near New York City. Although white pupils earned higher scores than nonwhite pupils on both tests, the Metropolitan produced significantly greater differences between the races than the Iowa, at both grade levels. Factorial analysis of variance confirmed the statistical significance of these differences. Implications of Race X Test (suggesting S.E.S. X Test) interaction effects for program evaluation and instruction are briefly discussed.     

THE EFFECT OF PHYSICAL CONDITIONS OF THE TEST ROOM ON STANDARDIZED ACHIEVEMENT TEST SCORES

A group of 384 ninth-grade students were given a standardized achievement test, half under relatively poor physical conditions in an auditorium and half in relatively adequate physical conditions in regular classrooms. An analysis of covariance (using I.Q. as the covariate) indicated no significant difference due to the physical conditions.     

INCREASES IN TEST SCORES AS A FUNCTION OF MATERIAL REWARDS

In this study 81 experimental and 79 control subjects (randomly assigned to treatments) took Form A of the Nelson Reading Test, twice, with a four week interval between test administrations. Instructions for the retest varied for the E and C groups. The latter group was told that the test was readministered for purposes of assessing improvement. The E subjects were informed that by improving their previous score they would be eligible for winning a prize (candy bars, university sweaters, radios). Analysis of covariance indicated that the effect of the awards was significant (p < .01) in terms of number of items attempted and in terms of items correct. The adjusted mean increase for the E subjects was three months. The authors concluded that, if the terms of an actual performance contract would be applied to their results, they were to realize approximately $3,000 profit on a $75 investment.
