This study focuses on the semantic development of individual lexical items, as viewed from a semantic features perspective. It involves four narrow semantic domains, a sample of elementary school-children and their teachers, and two native language groups, English and Spanish. Semantic development is studied through the process of equivalence…

Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…

This paper describes a method of reflective practice called "critical incident" which was used to examine teacher trainees' educational assumptions. A qualitative case study of one fifth-year teaching intern (Amy) at the University of Tennessee represents the experience of seven other master's level students already practicing within the…

This book is intended to provide specific instructional help for educators planning remediation of deficits identified by the Wechsler Intelligence Scale for Children III (WISC-III) and for educators writing individual educational plans. An introduction notes differences between the WISC-R and the WISC-III. The guide is arranged in four subtest…

This paper reports the findings of an investigation into the development of the use and understanding of locative and temporal prepositions in 94 children aged from 18 months to 8 years. The research was carried out as part of the Project "Language Development in Pre-School Children," directed by Gordon Wells, at the University of…

Elusive developmental processes are most often examined in the context of the philosophic problem of scientific determinism. The Markov process model, enhancing a probabilistic viewpoint for the explanation of developmental data, should be restricted. Attention should be focused on the immediate context and situational setting of a subject. The…

Sex differences in cerebral organization and functioning, and the apparent superiority of males in spatial ability are examined in this paper. Attention is given to several kinds of cognitive and perceptual tasks in which sex differences in spatial ability have been shown to exist; among these are tasks involving: (1) recall and detection of…

This paper examines the images middle school students have of science and technology, the workplaces, and the relevant professions. It also describes the effect on these images caused by an instructional initiative, "Investigation into Science and Technology" (IST), designed to introduce students to science and technology in the "real life."…

This guide provides group activities for teachers to aid in planning a multicultural curriculum for developing sensory perception in children. The guide emphasizes the cognitive processes involved in sorting out sensory data and the use of multicultural materials as resources for sensory experience. Activities are presented in six sections.…

The objectives of this report are to determine whether there is a need to establish a statewide policy of early education in Ohio, to define what priorities are implied by such a need, and to suggest relevant recommendations for the establishment of a policy, if needed. Sixteen chapters (nine-tenths) of this report present information from…

The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…

The inferior performance of external locus of control (LOC) subjects (Ss) on achievement tests has been attributed by many researchers to cognitive and perceptual deficiencies. Several studies have shown that advance organizers (AO) which provide optimal anchorage and mobilize existing relevant concepts, facilitate learning of verbal material.…

This study was designed to select and explore a research battery which, when administered at the beginning of the school year, more adequately predicts end of year reading achievement than have previously-used tests and test batteries. The tests used were perceptual-motor and cognitive-intellectual, with the most adequate predictor tests…

The purpose of this paper was to relate Jean Piaget's stages of the learning process to the developmental aspects involved in reading comprehension. The need to correlate the developmental stage of the child's mind with the right types of activities was stressed. When a child has succeeded in the task of relating knowledge and affect to language…

Examines the relationship of grade level to children's ability to make musical discriminations when elements are presented simultaneously. Utilized a brief instructional period, listening tests, and singing tasks. Results indicated significant differences between grade level, types of discrimination, and musical interactions. Includes statistical…
