A seventh-grade class took tests in block design problems to determine the importance of three techniques of programed instruction. The techniques under consideration were sequencing, cueing, and individual response. The research design looked at the performance of three ability levels (high, medium, and low) divided by sex over five program…

A signature tree is a binary decision tree used to classify unknown patterns. An attempt was made to develop a computer program for manipulating signature trees as a general research tool for exploring machine learning and pattern recognition. The program was applied to the problem of speech recognition to test its effectiveness for a specific…

This study was concerned with determining the validity of the Slosson Intelligence Test (SIT) using the Stanford-Binet Intelligence Scale (S-B), Form L-M as the validity criterion. The sample consisted of 724 students enrolled in 10 public school systems in northeastern Massachusetts. Using the Pearson-Product Moment formula a coefficient of…

Individual differences in general intelligence and in 8 different special aptitudes or skills were hypothesized to be independent of family size and birth order indices. Evidence to the contrary, in the form of linear correlations, was predicted to be due to the confounding influence of socio-economic factors. Among the more familiar demographic…

This study, which is a partial replication and validation of the 1962 Laurendeau and Pinard study of causal thinking, investigates cross-cultural differences among three age levels of Canadian and American school children in the development of causal thinking.

An intelligence test for use with rural Filipinos was developed using 25 general information questions. The questions bear on experiences common to most rural Filipinos. The methods of development and analyses are described. It is suggested that this strategy could be used with other peasant groups where an assessment of intelligence is needed in…

This essay discusses testing of the disadvantaged and the possibilities for new approaches to the problem. The black community's resistance to testing and the legal implications of employment and educational discrimination which results from testing are discussed. The objections to testing the disadvantaged are reviewed. At the end, it is hoped…

This study refutes the Elashoff and Snow (1970) critique of "Pygmalion in the Classroom," a study by Rosenthal and Jacobson (1968) on the effect of favorable teacher expectance on pupil achievement. Among the theses considered erroneous are: (1) That there is a wide variation in apparent results when different methods of data analysis…

The Augmented Human Intellect System (AHI) has been designed to facilitate communication among knowledge workers who may accomplish their entire job utilizing this advanced technology. The system is capable of sending information to geographically distributed users. It permits access to and modification of stored information by a number of persons…

The research summarized in this paper was conducted on the Pine Ridge Indian Reservation in South Dakota. The purpose of the developmental study was to explore the cognitive aspect of development rather than to explore the personality as a whole. The Clinical Exploratory Method of Piaget was employed, which focuses primarily upon an experimental…

The views of E. L. Thorndike on the future of measurements of abilities, expressed 25 years ago, are summarized, and the future of measurements of abilities as it appears now is examined. Opportunities for improvement now arise mainly from increasing social concern for effective education. Measurement technology has developed rapidly and cannot…

Based on the premise that perception is a continual series of simple hypotheses about the external world which are built up and selected by sensory experiences, this book explores in detail some of the major findings in perception and speculates about interconnections between sensory experiences, brain function, perception, and language and…
