A study was conducted by the Navy to develop and evaluate human performance reliability estimates for electronic maintenance. Data were collected using the Personnel Identification Information Forms, the Technical Proficiency Checkout Form, and the Job Performance Questionnaire. On the basis of the total number of uncommonly effective and the…

Forty-three students participated in a laboratory experiment involving estimation of qualitative similarity between items sampled from ten conventional tests of intellectual performance. Estimated similarity could tentatively be described as a function of positive inter-test correlations as determined from another group of 123 individuals with the…

The purpose of this research effort is to validate the utility and effectiveness of a unique human performance measurement technique developed under ONR contract (N0001467C0107). Performance data on eight Navy ratings was collected from ships of LANTFLT and PACFLT. This report is the last in a series of technical reports on the statistical…

The goal of this investigation was to derive a common battery of tests for both whites and negroes, and utilizing, if possible, uniform selection standards. (Author)

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…

The relationship between performance on various Piagetian and reading achievement tasks as examined through 26 correlational studies is reviewed. The following areas of concern are addressed: (1) sample characteristics of the subjects; (2) classification of the Piagetian tasks into five categories of logical operations, spatial concepts, general…

The pricing of household work can be based on standardized times established for component parts of the job. Techniques for determining these standardized times and the component parts were developed in a study conducted at Purdue University and supported by a federal grant. After a preliminary survey of homemaker practices in cleaning living…

The military utilizes tests extensively and should be aware of current testing problems. A conference composed of members from the business, educational, and military communities, both foreign and domestic, was held and these major issues addressed: (1) The Development of Training Requirements; (2) Personnel Assignment Using Interest Inventories;…

Content and task dimensions of social studies items were studied using factor analytic techniques. These items were developed to measure concept attainment using a completely crossed design with 30 concepts and 12 tasks. Conventional factor analyses were performed, separately for boys and girls, for concept scores and for task scores. Three-mode…

The report describes a number of experiments designed to compare the acquisition of a compensatory tracking skill in adaptively controlled and open loop conditions. It covers one dimensional tracking and two dimensional tracking. Several one dimensional tasks were employed in order to control the degree of subskill interference and memory load.…

Two experiments were performed using messages of digits presented auditorily at a rate of two digits per second. In both experiments, messages of seven different lengths were employed, consisting of 4 to 10 digits in Experiment 1, and of 2 to 8 digits in Experiment 2. The Ss were asked to recall them in the original order, and then to estimate the…
