That additional exposure to memorial material improves subsequent retrieval probabilities was explored. The effect of a recognition test on subsequent recall and recognition of categorized lists was studied. Prior recognition tests increased recall of original items, but also increased intrusions. Similarly, prior exposure increased hit rates and…

Two strings of letters were presented. Subjects were instructed to indicate whether the second string contained the same elements as the first, regardless of position. Reaction time increased with the number of positions that the letters were displaced. Results indicate that order may be an important factor in retrieval from memory. (Author/BW)

Development of an information processing model provided concepts for analyzing test anxiety. Results implied that worry reported by high test-anxious students is due to inadequate knowledge of subject matter rather than a personality characteristic. Programs emphasizing learning strategies and coping techniques are urged. (CE)

Presents a computer simulation testing semantic networks and spreading activation models of human memory. Describes how a sentence is encoded by building a working memory structure from its words and from semantic memory concepts related to its meaning. Retrieval processes use cue words or sentences to locate working memory structures. (Author/MES)

Presents a model used to help students of instructional technology conceptualize the range of instructional designs they might utilize and which could be used to classify existing materials for easy reference. (CHC)

The authors define three levels of content complexity in ethnic materials and present a sequence for incorporating complex ethnic content with an appropriate instructional strategy in order to elicit a higher level of cognitive functioning. (Author/SJL)

Several different conceptions of the relationship between learning and development are considered in this article. It is argued that dialectical and ecological developmental orientations might provide a useful basis for synthesizing the contrasting frameworks of the operant, information processing, learning theory, and knowledge acquisition…

Discusses conceptualization in relation to technology education. Includes an evaluative instrument to assess instructional models. (JOW)

Recommends an instructional design strategy derived from information processing theory and research which would include the planned presentation of retrieval events and encourage learners to manage some aspects of their own learning. Twelve references are listed. (MER)

This article summarizes results from studies of the organization and development of cognitive abilities in adults aged 20 to 60 years old. Theories of intelligence stipulating a hierarchy of intellectual functions, with fluid and crystallized intelligence at the top, are supported. Six conclusions on age differences are offered. (Author/RD)

The holistic-discriminability model of object-space perception recognizes various classes of stimuli having different task requirements, with few assumptions. The alternative analytic model, contrary to Dykes and Cooper, is inadequate; it involves many assumptions, predicts only a limited set of data and makes some incorrect predictions.…

A curriculum model in logic is proposed for learning disabled students based on reasoning and content needs. A diagnostic test with probes yields a profile of the child's reasoning ability and pinpoints areas of strengths and weaknesses. Three levels of instruction are provided: thematic concrete, specific concrete, and abstract. (CL)

Effects of the CoRT (Cognitive Research Trust) Thinking Project with slow learners in the United Kingdom is discussed. The aim of the project is to provide the framework which helps children arrive at a response to problems. (PHR)

An eight-phase model of processes involved in mathematics problem solving is presented. At each phase, results from factor-analytic studies are used to suggest abilities relevant and prerequisite for successful completion of the phase. Presentation of the model is followed by a discussion of implications for teaching and research. (Author/MK)

Defines a "communicate"--the objectification of a subject's internal model of the object of reality by means of a certain set of physical signs--and examines its information value with relation to intelligent systems. (CWM)
