A discussion of the recent diagram and attention theory and research surprisingly suggests that a single flow diagram with instructive questions constitutes an effective learning medium in terms of verbal chaining. (Author)

The purpose of the present work was to investigate the relation between pattern goodness and accuracy of reproduction in backward masking. It may be hypothesized that good patterns, being easier to encode as wholes, will be reproduced more easily than poorer patterns. Four experiments were performed. (Author)

A decision matrix as a technique for making rational planning decisions is presented. (EC)

The present experiment was intended as a further elaboration of the effects of nonphysically aversive stimulation on subsequent performance, in order to determine the applicability of the helplessness model to the human subject. (Author)

Some applications of mathematics to bicycle gearing, speedometers, and bicycle braking are discussed. A method of calculating bicycle speed is developed. (MP)

Describes an economic modeling approach to evaluating the cost and benefits associated with providing information services through information centers. The approach develops a framework for understanding observations about the demand for scientific and technical information and integrating these observations with fundamental economic principles.…

This is the first in a series of information papers that are intended to supply information on matters of general importance to the educational system. It focuses on the complex committee structure for curriculum development in Scotland beginning in 1965 and outlines its growth up to the present. (Editor/RK)

An attempt was made to uncover dysfunctions in any of the mechanisms in selective attention, as well as any unusual allocation policy, which possibly exist in schizophrenia. (Author/RK)

A previously proposed model for memory based on neurophysiological considerations is reviewed. It is extended by introducing positive feedback of a set of neurons onto itself and allowing the neurons to saturate. The resulting model is analyzed by distinctive features, categorical perception, and as it applies to probability learning. (Editor/RK)

A study of the kinds of computer programs children write and the types of programming concepts with which they have difficulty. (DAG)

A new computation of school retention rates by the National Center for Education Statistics indicates that about three-fourths of the young people today are earning high-school diplomas. Discusses the development of those statistics and the estimated retention rates from the fifth grade through college graduation in the United States during the…

In an experiment on the effects of blank trials on probability learning, some informational parameters were varied. The results showed that the presence of blank trials shifted response probabilities toward the guessing level. Data from other experiments are considered, and the relevance of the results to studies of behavior with concurrent…

A flipchart reference booklet with nutrition information related to family planning is described. Users can assess information on a variety of topics by selecting tabbed headings, including possible nutritional implications of each of the major contraceptive methods, nutritional risks, and the four basic food groups.
