Two well known directional (one-tailed) tests of significance, mean difference and correlation coefficient, are presented within the multiple linear regression framework. Adjustments on the computed probability level are indicated. The case for a directional interaction research hypothesis is defended. Conservative adjustments on the computed…

A study and replication tested whether memory aptitudes interacted with note-taking, paying attention, or responding to test-like events during lecture instruction. Regression analyses were accomplished by means of the single predictor-single criterion case of the modified Johnson-Neyman statistical technique. A disordinal interaction between…

The central concern of this book is the pursuit of experimental methods whereby grammatical and semantic inquiry can be put on a satisfying objective basis. (To state that the aim is to find out whether a given linguistic form is "acceptable" is true, but an oversimplification which is misleading because it implies a "yes or no" decision and…

Traditional employment screening procedures; the interview, the job application, the high school diploma and work try-outs, may screen out rather than screen in the hard-to-employ. Employment testing may reflect the trainee's anxiety, his cultural differences, the irrelevancy of test questions, and his inability to read rather than his potential…

The design, development, and evaluation of an integrated Computer-Directed Training Subsystem (CDTS) for the Air Force Phase II Base Level System is described in this report. The development and evaluation of a course to train computer operators of the Air Force Phase II Base Level System under CDTS control is also described. Detailed test results…

To determine the effect of purpose, background information, and distractions on the listening act, 692 fourth graders in 24 classrooms were randomly assigned to eight treatment conditions before listening to a 12 minute taped dramatization. One half of the classes were told they would be tested on the taped material; the other half were given no…

Studies (2) of auditory memory performance are reported. Children were asked to recall material which permitted different language habits to be used (structural, and meaningful). Lower socio-economic status (LSES) Negro children performed more like their middle socio-economic status white (MSES) counterparts on non-contingent strings. When…

This study of student attrition in a public junior college used personality measures and demographic data as independent variables. Student dropout, defined as failure to complete the semester or to transfer to another institution, was the dependent variable. Instruments used were the Omnibus Personality Inventory, the Adaptive-Flexibility…

In the fall of 1968, 269 males and 167 females at Central Virginia Community College were administered the Holland Vocational Preference Inventory. Statistical comparisons were made scale-for-scale between these students and national normative group average scores. The comparisons of means and standard deviations were analyzed by "t"…

Exhibit development, as conceived in this report, is an evolutionary process, drawing the museum visitor into the collaborative venture of testing and improving the exhibits. The findings of contemporary learning research were put to work in the arrangement of activities and specimens that engaged children through self-instructional sequences. The…

Including the General Aptitude Test Battery (GATB) in a school testing program should be the result of careful planning and formulation of goals. The investment may, however, be worth the advantages that can be achieved by providing students with information that may help them formulate individual educational and vocational goals and make related…

The primary purpose of the present study was to investigate empirically the effect of multiple hypothesis testing on error rates in factorial ANOVA designs under a variety of controlled conditions. The per comparison, per experiment, and experimentwise error rates were investigated for three hypothesis testing procedures. The specific conditions…

Basic to many psychological investigations is the question of agreement between observers who independently categorize people. Several recent studies have proposed measures of agreement when a set of nominal scale categories have been pre-defined and imposed on both observers. This study, in contrast, developes a measure of agreement for settings…

Five computerized narrative assessment reports are discussed. These are: (1) the Teaching Information Processing System Student Report, used for a college economics course; (2) the Preliminary Scholastic Aptitude Test (PSAT) Score Report; (3) the Programmed Composition of Psychological Test Reports employed at the Mayo Clinic for reporting results…

It is argued that, by design, norm-referenced tests (NRT) and criterion-referenced tests (CRT) are conceived with different frames of reference. They are not totally exclusive of each other, but they do direct attention to different uses and references for information and decision making. Their combined contributions allow a more detailed and…
