The Tab Item: a Technique for the Measurement of Proficiency in Diagnostic Problem Solving Tasks

RECENTLY, as part of the development of a battery of tests to measure the proficiency of Air Force maintenance personnel, a type of test item has been developed which may prove to have widespread application in the general area of psychological testing. The Tab Item, so called because of its construction, was originally designed to short-cut the more expensive and time-consuming work-sample type of performance measure without sacrificing to a large extent the added validity that such measures usually possess over paper-and-pencil group

The Reliability of Inconsistency

IN previous articles (5, 6, 7) the writer has been concerned with a pattern of inconsistent responses on certain wide-range achievement and aptitude tests. An inconsistent response is defined as a change in response to a test item on a repeated administration of a test. On the basis of the properties of this pattern it was shown: (i) that there was a predictable relationship between test score and the number of inconsistent responses on a test, and (2) that a test score corresponded to the maximum point of the distribution of inconsistent responses. In this previous work an estimate of the distribution of inconsistent responses was obtained from two administrations of

Cross-Sectional and Longitudinal Results in a Study of Age-Related Changes1:

STUDY of the effects of aging on various areas of human behavior is still in its early stages. One indication of this is the fact that little information is available on the effects of aging upon complex skills critical to the individual’s adaptation to his environment. Previous studies have been largely concerned with tasks whose significance for life situations is not known (1, 2). An additional symptom of the undeveloped state of the field is the fact that the contribution of different types of methodology remains unclear (8, 10). In particular, the value of data obtained by cross-sectional methods has been questioned for some time. Only recently with the increasing emphasis on aging effects has this problem begun to receive intensive consideration (1, 10). The present study had two primary objectives. The first was to
