Critics of null hypothesis significance testing suggest that (a) its basic logic is invalid and (b) it addresses a question that is of no interest. In contrast to (a), I argue that the underlying logic of hypothesis testing is actually extremely straightforward and compelling. To substantiate that, I present examples showing that hypothesis…

The purpose of this study was to determine the extent to which Crockett's Role Category Questionnaire (RCQ) is confounded by verbal ability. Participants included 285 undergraduates from a large southern university. The results show the RCQ to be independent of the verbal abilities measures. (Author/BW)

The General Education Performance Index (GEPI) is a comparatively short test covering the same content as the General Educational Development Test (GED), which takes ten hours to administer. Correlations of the subtests of the GEPI with the GED ranged from .28 to .57. (JKS)

Effects of item presentation mode on degree of leniency bias in responses to field research questionnaires were studied. Two modes were examined: first with items measuring the same dimensions grouped together and second with such items distributed randomly. The random mode showed substantially less leniency response bias. (Author/BW)

The empirical evidence does not support the prevailing conventional wisdom that it is advisable to mix positively and negatively worded items in psychological measures to counteract acquiescence response bias. An experiment, evaluating subjects' ability to respond accurately to both positive and reversed items on a questionnaire, analyzed post-hoc…

The Nonsexist Personal Attribute Inventory for Children (NPAIC) was administered along with the Piers-Harris scale to children in fifth through eighth grade. A correlation of .49 was found between the two scales. The NPAIC was found to be a reliable, valid self-concept scale for females and males. (Author/GK)

Past practice of operationalizing the concept of fakeability of psychological tests is reviewed. The strengths and weaknesses of these indices are discussed in the light of a proposed new definition of fakeability based upon Naylor's model of measurement accuracy. (Author/JKS)

Cross-cultural validity studies for psychological instruments may result in overestimation of structure invariance due to some items being scored on more than one scale. This problem, called the common-item effect, is investigated with some data from the literature. (JKS)

Two tests of critical thinking (the Cornell Critical Thinking Test and the Watson-Glaser Critical Thinking Appraisal) were evaluated by a panel of psychologists relative to the validity, reliability, and error of measurement standards stated in the "Standards for Educational and Psychological Tests," 1974. (PN)

An algorithm for updating the means of variances of a norm group after each computer-assisted administration of a test is described. The algorithm does not require storage of the whole data set, and provides for unlimited, continuous expansion of the test norms. (Author)

The authors suggest that there may be a phenomenon of posttest sensitization which could affect the generalizability of experimental results in the way that pretest sensitization does. A quasi-experimental design is proposed to test for such a phenomenon. (JKS)

Different forms of a vocabulary test were administered to college students. Results indicated that as the frequency of specific determiners increased, they formed increasingly strong but differential guessing response sets in high and low scoring groups; however, the magnitude of the effect was much stronger for position specific determiners.…

The essay-type items of postgraduate achievement examinations in psychology for students at the University of Peshawar were classified, and the relative frequencies of the items were compared with those for psychology examinations administered at a British university. The dimensions of Analysis and Synthesis appeared to be underrepresented at…

This study determined the degree to which the Non-Language Test of Verbal Intelligence, developed to measure verbal ability through a nonlanguage medium, could measure verbal intelligence. Correlation with the Differential Aptitude Test-Verbal suggested the existence of some common, as well as some uncommon, factors between the two tests.…
