This paper presents an overview of the knowledge afforded man from research into personality. Approaching his topic from a position valuing the study of persons from complementary psychological perspectives, the author attempts to derive some conclusion about human behavior and personality. He discusses the findings that there is basic continuity…

The problem of interpreting the dimensionality underlying binary test data is addressed. Medical school students were tested on both achievement and aptitude measures. The person-by-test (aptitude) interaction matrix was factor-analyzed to identify patterns of individual differences. The resultant groups of similar patterns were used as the…

This paper will discuss the results of a series of computer simulations comparing the Rasch logistic model to a series of models departing to various degrees from its assumption of equal discrimination power for all items. The results have implications for test construction and test scoring, indicating how closely the conventional raw score…

Individual differences in the ordered recall of list of digits are examined experimentally. The resulting evidence argues that neither differences in rehearsal strategies nor differences in the tendency to group and chunk the digits are major determinants of differences in digit span size. Further experiments attempt to pinpoint the source of…

Three related experimental studies analyzed rate and accuracy of test response under time-limit and no-time-limit conditions. Test instructions and multiple-choice vocabulary items were administered by computer. Student volunteers received monetary rewards under both testing conditions. In the first study college students were blocked into high-…

Statistics from research studies indicate that boys have more difficulty than girls in learning to read. As a result, changes being made in the educational system are aimed at adapting early instruction to the individual needs and capacities of boys as well as girls. This booklet focuses on past research on sex differences in reading achievement,…

Summarized are results of an investigation of elementary age listeners' preferences for the rate of presentation of recorded information in which it was found that children, when given the opportunity, will manipulate the rate of presentation of recorded information, that they have a preference for rates of presentation, and that individual…

To learn if differences in age, intelligence, and sex account for differences in children's memory of TV commercials and "degree of insistence" (DI) after viewing them, 54 gifted, 71 normal, and 53 educable mentally retarded children (of both sexes, 7-13 years) were questioned. The mediating influence of the three independent variables on DI was…

This paper deals with a study designed to pursue the question; "What treatment by whom is most effective for this individual with that specific problem under which set of circumstances?" One of the objectives of the study was to determine if there was any relationship between two predictor variables, personality type (extraversion-introversion)…

Special features of a nongraded elementary school program are reviewed as a guide to those wishing to implement the concept as a way to provide individualized instruction and quality education for all students. Emphases include the individual differences of students, the restrictive character of graded schools, curriculum patterns, levels of…

One of the most pressing needs in education today is the adaptation of instruction to individual characteristics and background. The Individually Prescribed Instruction project (IPI) of the University of Pittsburgh represents an investigation into the requirements for and the problems encountered in developing a system for individualizing…

This study seeks to identify in advance the personality traits of freshmen who will later seek counseling because of psychological discomfort. When clients were compared with nonclients (415 males, 257 females), psychiatric clients (10 males, 16 females) were higher in impulsivity, and lower in order and cognitive structure; and personal…

Two separate subject matter areas, which were felt to represent two distinct types of learning situations, were selected for investigation, namely, a kind of logico-mathematical procedure--the transportation technique, and a visual form discrimination task--aircraft recognition. Two separate courses were developed for each subject matter area. One…

This paper is concerned with the question of relationship among preferred perceptual modes, selected independent variables which cause individual differences, and the resulting effects on conceptual behavior. Subjects ranged from four and one-half years to eight and one-half years of age. Each child chosen by the plan was screened for color…

The purpose of this study was to examine the relationship between the various techniques used to estimate the time required by the human to process a visual stimuli, i.e., recognize a stimulus input into the visual perceptual system. Sixteen tests of visual processing speed were administered to 110 undergraduate students. In summary, scores tended…
