We recently proposed a multi-channel, image-filtering model for simulating the development of visual selective attention in young infants (Schlesinger, Amso & Johnson, 2007). The model not only captures the performance of 3-month-olds on a visual search task, but also implicates two cortical regions that may play a role in the development of…

This paper offers a model of visual functioning focusing on three factors: (1) visual capacity, (2) visual processing, and (3) visual attention. Practical implications of visual therapy are considered, and intervention strategies with children with impaired visual functioning are suggested. (Author/DB)

Two experiments studied whether and how 5-year-olds integrate single facial features to identify faces. Results indicated that children could evaluate and integrate information from eye and mouth features to identify a face when salience of features was varied. A weighted Fuzzy Logical Model of Perception fit better than a Single Channel Model,…

The performance of eight adults with Asperger syndrome was compared with the performance of controls on a range of perceptual tasks designed to test two models of perceptual deficit: the central coherence deficit model and the hierarchization deficit model. Tentative support for the hierarchization deficit model was demonstrated. (Contains ten…

An experiment was performed to show that infants perceive auditory and visual stimuli within a common space and that they perceive the sound as an attribute of the visual object. Subjects were 22 infants aged 3 to 5 months. Each infant was presented with a toy that moved in a small arc from side to side of a small window at the rate of one arc per…

A model for sequencing tasks in the area of visual perception was developed. This paper reports an attempt to validate the structure of the model. The performance of 50 normal preschool children on a 47 item test was studied. The results obtained support the use of the model as a framework for developing visual perception tasks. (Author)

The purpose of this paper is to illustrate the parents' role in their child's visual guidance program, the philosophies behind the program, and the teacher's responsibility to child vision. The first chapter, on parent involvement, instructs them to provide an environment to stimulate intellectual growth and stresses the importance of the…

The development of visual perception skills in children with partial vision as well as developmental disabilities is considered. A model of visual learning is offered which incorporates the role of visual experience, movement, and visual learning. Specific teaching suggestions for developing visual attention and visual search skills are offered.…

Visual recognition, navigation, tracking, and imagery are posited to involve some of the same types of representations and processes. The first part of this paper develops a theory of some of the shared types of representations and processing modules. The theory is developed in light of neurophysiological and neuroanatomical data from non-human…

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…

Under the sponsorship of the National Project in Agricultural Communications, a series of 14 lessons by various authors has been compiled to serve as a reader or training manual in the field of visual communications. Several models of communications are outlined and evaluated. Many studies which concern themselves with the concepts of source,…

Analyzes the research strategies, stimuli, subjects, statistical strategies, and relative variables in 34 empirical studies on children's representation of three-dimensional objects. The studies fell into three categories: children's representation of spatial relationships within an object, between two objects, and studies that included both. (MJP)
