Describes procedures used to study abilities of chimpanzees to be taught written language. Words, sentences, questions, metalinguistics, class concepts, the copula, some quantifiers and if-then logical connections are investigated. Success seems attributable largely to non-linguistic cues. (JM)

A discussion of learning potential among educable retardates reflects the author's findings that some solved difficult problems on the Kohs block designs, some did not do well at first but improved after coaching, and some did not do well before or after coaching. Additional studies of these highscorers, gainers, and nongainers are cited which…

A teacher relates the experiences he and his classes had as a result of nonverbal instruction in mathematics. He tapped creative resources within himself of which he was previously unaware and his students became more involved in formulating the rationales of the mathematics being taught. (JP)

Reports on the effectiveness of visual illustrations used in conjunction with oral instructions. Results indicate that the reduction of realistic detail in an illustration does not necessarily reduce its instructional effectiveness and in many cases improves it. There were also significant differences in the effectiveness of different types of…

The original intent of this investigation was to evaluate the effectiveness of the Object Sorting Task (OST) as a predictor of learning outcomes, especially among minority children. The study results, however, have produced a subtle but significant shift of attention to the issue of possible differences in the cognitive organization of children…

This study was designed to investigate the nonverbal teacher behavior of wait-time. Wait-time is the silence in a conversation following a teacher or student utterance. The primary purpose of the investigation was to document some of the behavioral and cognitive effects of wait-time and to delineate the interrelationships between the various forms…

TWO SPEECHES PRESENTED AT THE CENTENNIAL TEACHERS INSTITUTE OF THE MARYLAND SCHOOL FOR THE DEAF IN MARCH 1968 ARE CONTAINED IN THIS BOOKLET ALONG WITH A SHORT HISTORY OF THE SCHOOL AND A LIST OF AGENCIES AND ORGANIZATIONS REPRESENTED. HELMER R. MYKLEBUST, IN "LEARNING AND EDUCATIONAL FAILURE IN DEAF CHILDREN--PSYCHONEUROLOGICAL CONSIDERATIONS,"…

One hundred twenty-eight preschool boys were subjects in a 4x2x2 factorial design to investigate the change in reinforcer efficacy as a function of prior stimulus exposure. The factors were: (1) amount of repetition, 5, 25, 45, or 65; (2) reinforcer, good or bell; and (3) satiator, good or bell. Two additional groups were run as control groups to…

Summarizes experiments indicating that a basic key to learning is the development of concepts of pattern recognition and the appropriateness of using a particular theorem. (Author/SK)

Notes that almost all computer engineering textbooks present algorithms using only verbal methods. Poses that engineering students' ability to handle graphic representation is crucial yet information is presented verbally. Summarizes the results of 12 replications on learner preference for graphic or verbal algorithmic techniques. (MVL)

The effects of prompting and confirmation on automated presentation of materials in discrimination learning were studied. Eight pairs of words or pictures were presented to 48 mentally retarded subjects (mean IQ 63, mean chronological age 163.4 months, mean mental age 103.3 months). Each subject's correct responses advanced the program and, in the…

Intended for teachers, educators, and specialists who are interested in the problems of learning disabilities, the text presents principles and practices necessary in the clinical teaching approach to children with learning disabilities. Areas considered include learning disabilities in general, the brain and learning, and special education and…

Three experiments tested whether qualitative differences in processing of verbal materials result from congenital hearing impairment. Subjects were children with reading levels equivalent to grades 4 to 6. Experiment 1 used repeated measurements with two modes of response and two kinds of cues; experiment 2 used acoustic similarity to produce…

After intensively studying for several years the thinking processes of members of a tribal group in Western Africa, the Kpelle, the authors examine the relation between culture and cognitive development. The following issues are discussed: (1) an analysis of the terms "culture" and "cognition"; (2) an ethnographic description of the Kpelle…
