Two experiments explored the nature of perceptual development in 5- and 10-year olds and adults. The primary finding was that preassessed salience significantly influenced 5-year olds' ability to discriminate two objects, while salience did not affect 10-year olds' or adults' response times. Results showed that salience effects in perceptual…

Three experiments explored 5- and 7-month-olds' intermodal coordination of proprioceptive information produced by leg movements and visual movement information specifying these same motions. Results suggested that coordination of visual and proprioceptive inputs is constrained by infants' information processing of the displays and have…

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…

Through the process of distancing, children develop an understanding of the differences between themselves and others, themselves and objects, and objects and representations. Adults can support progressive distancing in children who are congenitally deaf-blind by applying strategies, such as the hand-under-hand exploration of objects, the…

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…

Children with congenital blindness are delayed in understanding other people's minds. The present study examined whether this delay was related to a more primitive form of inter-subjectivity by which infants draw correspondence between parental mirroring of the infant's display and proprioceptive sensations. Twenty children with congenital…

Early intervention approaches for facilitating motor development in infants and children with Down syndrome have traditionally emphasised the acquisition of motor milestones. As increasing evidence suggests that motor milestones have limited predictive power for long-term motor outcomes, researchers have shifted their focus to understanding the…

Educational taxonomies developed by Bloom, Krathwohl, and collaborators have been used for decades as frameworks for instructional objectives, curriculum design, and assessments of achievement. However, their scope is now too limited. The well-known cognitive domain is extended to include ideational functions of imagination and creativity, and the…

As classrooms in the United States become increasingly multicultural, teachers need to be aware of how and when racial attitudes develop in children in order to provide a supportive learning environment for children of any ethnic heritage. This study examined racial awareness and attitudes in children between 3 and 10 years of age. Subjects were…

This monograph describes the Perceptive Motor Skills Program (PMSP) being used with adolescents and adults having mental retardation in Catalonia, Spain. The program is based on the following principles: chronologically age appropriate activities; use of daily living tools; multiple objectives and working materials; and balance between…

Ten diagrams and step-by-step instructions for an art activity in which middle school students practice drawing in perspective are provided. Students practice basic rules of perspective such as (1) determining the horizon line or disappearing point, (2) drawing parallel lines and drawing above and below eye level. A brief test of teacher…

This paper discusses and review the ideas of Hoyt L. Sherman who taught art and visual perception at the Ohio State University. It explores some of the psychological sources for his work and ideas about the teaching of drawing by seeing which relates to the work and ideas of Adelbert Ames, Jr. The article traces the influences of both Ames and…

Research on hemispheric mode functioning indicates that some connections exist between learning disabilities (LD) and right-mode dominance, which suggests that instruction should be offered to develop right hemispheric (spatial perception) abilities in LD persons. The influence on student drawing of the right-left hemispheric shift during reading…

Four elements of clinical programming must be considered during development in order for a software program to be truly useful in rehabilitation: presentation of a useful task; treatment parameters selectable by clinicians; data collection/analysis; and authoring capability. These criteria govern the development of all Brain-Link Software…
