The investigation studied the effects of different methods of conveying test instructions on the performance of 54 deaf children (6 to 8 years old) on pattern recognition tasks. Ss were randomly assigned to one of three methods of conveying test instructions: simultaneous communication method, pantomime method, and demonstration method. Ss were…

This study explores the reason why very young infants are unable to respond differentially to faces and the cause for developmental changes in infant face perception by age 3 months. Linear systems analysis (LSA) and the contrast sensitivity function (CSF) were used to estimate the facial pattern information available to 1- and 3-month-old…

A study was designed to discover whether readers use simple story grammar categories (setting, beginning, development, and conclusion) to organize the propositions of a story. Nineteen proficient readers were given a list of randomly ordered propositions that made up a simple story structure. Each reader was instructed to group the propositions…

This paper is a theoretical discussion of several functions of knowledge systems based on the idea of partial matching, that is, comparison of two or more descriptions by identification of their similarities. Several knowledge system functions are described in terms of partial or best matchings including analogical reasoning, inductive inference,…

Research was done to develop techniques to facilitate natural communication between computers and people, other computers, and real time devices. The work was divided into tasks covering representation of semantic information, special purpose languages, real-time input-output, pattern recognition, and time-sharing research and modeling.

The final report of a two-year study concerned with the digital-computer processing of graphical data. Five separate investigations carried out under this study are described briefly, and a detailed bibliography, complete with abstracts, is included in which are listed the technical papers and reports published during the period of this program.…

This report summarizes research concerning stimulus analyzing mechanisms, giving the main experimental findings and theoretical developments. Most of the data and the experimental findings are to be found in the 89 publications listed in the bibliography. The research is discussed under five main headings: (1) shape recognition, (2) selective…

An activity similar to magic squares is described. (SD)

Described are results obtained by students investigating double-diagrams, including discoveries of properties and accompanying proofs. (MP)

Relationships between the linear dimensions, surface area, and volume of parallelepipeds are examined. (SD)

An activity that offers computational practice, pattern recognition, and the formulation of generalizations is described. (JT)

Assessed the ability of 5-month-old infants to discriminate between auditory tone patterns differing in temporal arrangement but utilizing the same component tones. Heart rate change provided the measure of pattern discrimination. (JMB)

A familiar Christmas song described as a second-year algebra problem is presented in "The Twelve Days of Christmas". Five strategies for solving inequalities are discussed in "Solving Algebraic Inequalities". (JT)

This paper discusses ways of discussing limits in the secondary classroom. Particular attention is paid to showing that hypothesized answers are not limits to given sequences. (SD)

Two experiments demonstrate that 10- and 13-year-olds can learn to detect interactive patterns in data. Results also indicate the advantages of creating formal models of solution strategies and using them as a basis for instructional procedures. (Author/DEP)
