Twenty children in each of grades 2 and 4 were given a reaction time task of the type in which Sternberg (1969) shows high-speed, serial, exhaustive scanning of information in memory. On each trial subjects were asked to memorize two, four, or six pictures and were then presented with a single picture probe. The subject made a key-pressing…

This research on factors influencing verbal learning and retention has used new techniques, attacked new problems, and tested new theories while trying to keep the experiments systematic. Studies conducted involved (1) the effect of varying the length of the intertrial interval on the learning and retention of different types of learning tasks;…

Progress is reported on four research tasks. An experiment tested the effectiveness of a computer-based phonology instructional system for second-language learning. In research on models of human-computer interactions, experiments were performed demonstrating that the provision of certain incentives to the users of a time-sharing system can have…

To investigate the underlying factors of visual discrimination, memory, rule abstraction, language, and serial ordering in reading success, 79 poor and 65 good deaf readers were administered a battery of tests. Poor readers were deficient in lower-order visual discrimination and memory abilities; higher-order visual discrimination skills were…

Two experiments comprised this study comparing the ability of children from ages 4 to 12 years to discriminate the order in which items from a previously presented sequence of stimuli had been presented. The hypotheses were that the discrimination of recency (DR) improves with age, that broader separations of test items are easier to discriminate…

This paper examines the developmental stages of haptic perception (the process of recognizing objects by the sense of touch alone), and attempts to clarify some conflicting results of studies of the effects of memory and object type. The paper also presents a specific study of haptic perception in 144 preschool and kindergarten children from…

A research project involving 16 experiments investigated the nature of the encoding process for verbal materials, particularly differences arising from mode of presentation. The results showed that a change in mode of presentation of items produced a recovery from interference in short term retention. Since intermodal interference was lower than…

Two studies are reported. The first is based on Piaget's assertion that the child's representation of his world is dependent on the level of cognitive development at which he is currently functioning. Forty-eight normals and 48 retardates were given a visual memory task. They were asked to recall a configural presentation in a number of ways,…

The stated purpose of the text is to review and interpret current behavioral research in mental retardation (including that done abroad) and to provide a forum for theories and new approaches. Eight chapters by different authors focus on the following subjects: medical-behavioral research; recognition memory: a research strategy and summary of…

The ability to anticipate elements in sequence is the foundation of all language skills. Because of its naturally high redundancy, it is almost always possible in the normal use of language to partially predict what will come next in a sequence of elements. The central feature of language processing is expectancy for successive elements. A very…

Tasks involved in paired associate learning (attention, perceptual learning, visual and auditory memory, response learning, and stimulus-response connections) are identified as some of the same skills and strategies involved in learning to read. Two studies on visual memory, the developmental lag hypothesis, and reading ability are examined to…

This paper discusses various theories of the role of memory in vocabulary acquisition and storage. Several research models are described, and theoretical considerations and questions are presented. The lexicon is seen as an element of grammar; an understanding of lexicon organization is important in the understanding of vocabulary acquisition.…

The symposium on the physical and psychomotor aspects of sports covered a variety of topics. Among those contained in this report are: discussions on the taxonomies of sports; the time dimension of physical activity including response variables, judgment of temporal order, and duration discrimination; memory; information and its use in physical…

Learning is not a simple unitary process. This paper identifies three qualitatively different phases of the learning process. In one phase, the learner acquires facts and information, accumulating more structures onto the already existing knowledge structures. This phase of learning is adequate only when the material being learned is part of a…

Reports on a study that sought to test theories which predict that spacing between two items to be learned improves the probability of remembering at least one of the items. (AM)
