Describes two studies investigating the development of recursive thinking in 60 Dutch children five, seven, and nine years of age. The first study replicated earlier research employing a verbal production procedure. The second study used verbal comprehension procedures and concluded that development appears two years earlier than indicated by the…

Twenty-six deaf adolescents received instruction in a structured program of cognitive education called "Instrumental Enrichment." The program addresses, among other processes, comparison, classification, logical progression, spatial orientation, analysis and synthesis, and syllogistic thinking. Following training, the subjects showed…

Investigates the relative influence of speech and pointing gesture information in the interpretation of referential acts among children averaging three and five years of age and adults. (HOD)

Examined infants' tendency, from a few days to nine months of age, to prefer infant-directed over adult-directed speech. Results suggest that exaggerated pitch contours that characterize infant-directed speech may become salient communicative signals for infants through language-rich, interactive experiences with caretakers and increased…

Discusses approaches to the problem presented in understanding consciousness as a yet undiscovered process of interacting neuron activity. Presents the historical context of research in the area of human awareness and identifies research necessary to scientifically explain how the brain relates to the mind. (MCO)

Examines perceptions of adults compared with preschool children in assuming object permanence or discontinuity of existence when an object is removed from their immediate perceptual field. Results showed that a belief in the possibility of the discontinuity of material objects is not unique to the minds of preschool children but can also be…

Investigated suppression of activation and retrieval paths to information stored in long-term memory. Subjects were 94 children in grades 1, 3, and 5. Found that the ability to intentionally inhibit the maintenance and recall of irrelevant information improves over the elementary years, and children are less able than adults to withhold production…

Argues that the operating characteristics of perceiving and remembering provide a foundation for progress on detailing the processes through which knowledge is realized in real-time tasks and in detailing the processes of developmental change. Includes three examples to illustrate how forming developmental hypotheses in terms of perceiving and…

Two experiments examined developmental changes in reasoning about intensive quantities--predicting mixture intensity of pairs of liquids with different intensities of red color. Results showed that cognitive averaging in this domain developed late and slowly. Predominating up to 12 years was an extensivity bias, a strong tendency to use rules that…

The relation between perceptual organization and categorization processes in 3- and 4-month-olds was explored. The question was whether an invariant part abstracted during category learning could interfere with Gestalt organizational processes. A 2003 study by Quinn and Schyns had reported that an initial category familiarization experience in…

Although numerous studies have indicated that older persons process visual information more slowly than younger persons, the precise nature of age-associated changes in the processing of visually presented information remains unclear. Older adults (N=18) and college students (N=18) performed a visual search task in which lists of words and…

This collection contains lessons in 4 subjects related to learning: (1) visual perception; (2) learning; (3) cognitive growth; and (4) moral development. Activities dominate each lesson and students are expected to do some experimentation outside the classroom. Each of the 20 lessons presents: (1) a synopsis; (2) objectives; (3) necessary…

Extensive research has proven that the functions of the two hemispheres of the brain tend to be qualitatively different. The left hemisphere, which for most people is dominant, is the major controller of speech, reading, and writing; it is the hemisphere toward which education traditionally has been directed. The right hemisphere excels in…

In training people to perform auditory identification tasks (e.g., training students to identify sound characteristics in a sonar classification task), it is important to know whether or not training procedures are merely sustaining performance during training or whether they enhance learning of the task. Often an incorrect assumption is made that…

Upholds the importance and need for including visuo-spatial skill exercises in science lessons. Provides suggestions for improving students' visualization skills and reviews the approaches that have been successful with students who were poor in visual skills. (ML)
