Describes the use of programmable calculators to perform classroom controlled experiments on economic models. The complete program for exploring the dynamics of the Harrod-Domar equation is given. Some difficulties encountered and statistical uses are mentioned. (BC)

Three word-identification experiments suggest that a model derived from experiments with pseudowords can be applied successfully to word identification. The data derived from the experiments confirm the role of higher order verbal units in word identification and suggest the structural components of a verbal-mediation theory of reading. (Editor/RK)

A set of rules is given for developing pairs of numbers which can be plotted on a graph, to provide practice not only with graphing but also with computation. (JT)

In a study of the effects of instructions on reaction times to judgments of the truth or falsity of sentences, 40 undergraduates were provided computer-assisted instruction by either the "true" or "conversion" model and required to judge 64 sentences of all possible combinations of true or false, affirmative or negative, and expletive or…

This is the third in a series of four articles, (including EJ 163 640 and AA 527 267), tracing the history of the National Catholic Educational Association through the contributions made by six of the Association's leaders. This article focuses on the work of Msgr. Frederick G. Hochwalt, NCEA chief executive, 1944-1966. (Editor/RK)

Explains the use of graphic representations of abstract concepts in teaching college level sociology students about data analysis and research design. (Author/DB)

A visual-spatial approach to the study of attention dysfunction was presented. The hypotheses of broadened and narrowed attention were tested by comparing peripheral visual discrimination of acute schizophrenic, chronic schizophrenic, and normal subjects within two regions of the functional visual field.

Analyzes the temporal features of the transient unconditioned stimulus preexposure effect observed by Cannon (EJ 123 672) and attempts to determine whether a preconditioned stimulus toxin presentation can both condition a backward taste aversion and interfere with the development of a forward aversion. (Author/RK)

Although the linguistic properties of sign languages, and of American Sign Language (ASL) in particular, are beginning to be studied, little work has been done on the functional properties of sign. Four experiments are reported in which signed messages were subjected to varying amounts of disruption using repetitive temporal interruption. Results…

The assumption that recall and recognition involve different processes has been attacked and defended in recent years on both theoretical and empirical grounds. This research extends the notion that retrieval processes are operative in recognition as well as in free recall of individual words. (Editor/RK)

This research examines how pictures differ from sentences on important memory dimensions, with specific reference to Bransford and Franks (1971). (Author/RK)

Explores whether or not systematic attributional differences between active and passive observers occurs similar to those that exist between actors and observers. (Author/RK)

This research assesses whether the presence of noise elements in a visual display affects the detection of target letters at the perceptual or feature extraction level of information processing and whether (a) input or processing channels operate in an independent or interactive fashion and (b) how the spatial relation between signal and noise…

This research was undertaken to explicate the role of behavioral rigidity and hypothesis behavior in concept learning of schizophrenics. (Author/RK)

Three experiments carried out second-order Pavlovian conditioning using either similar or dissimilar first-and second-order stimuli. All three experiments were designed to identify the effects of similarity upon conditioning as distinct from its effects upon sensitization or stimulus generalization. (Editor/RK)
