In an effort to make freehand drawing instruction more easily transferred to architectural design, a series of exercises was developed based on touch, movement, and vision. The intent is for students to mimic and develop empathy with the items they are drawing. Examples and illustrations are provided. (MSE)

An 18-item "Shortened Visuospatial Questionnaire" (SVS) was validated twice, first by verifying that children (ages 8-13) identified with the SVS questionnaire as having visuospatial learning disability (VSLD) (n=54) actually showed visuospatial deficits on psychometric evaluation, and second, by rating with the SVS a clinically identified…

A driver performance test revealed that school bus drivers were not adjusting the bus crossover mirrors so that all the pedestrian areas could be seen. In addition, the mirror adjustment was restricted by bracket supports. Describes mirrors that meet state vision standards and how they should be utilized. (MLF)

Focuses on the author's "semiotic self" by presenting questions and reflections. Discusses the overlapping groups to which one's multiple "selves" belong. Explains that these groups consist of people who share vocabulary, rituals, and understandings. (CMK)

The purpose of this paper is to describe a software package that can be used for performing such routine tasks as controlling listening experiments (e.g., simple labeling, discrimination, sentence intelligibility, and magnitude estimation), recording responses and response latencies, analyzing and plotting the results of those experiments,…

Research tells us we can learn complex tasks most easily if they are taught in "small sequential steps." This column is about the small sequential steps that unlocked the powers of digital photography, of portraiture, and of student creativity. The strategies and ideas described in this article came as a result of working with…

This paper presents an assessment tool which can be used during the first weeks of calculus to measure students' visual thinking skills. We have developed and applied this instrument in classes for the last three years, tabulating results and interviewing students on a regular basis. We discuss our findings and provide hints to using the…

When two masked targets are presented in a rapid sequence, correct identification of the first hinders identification of the second. This attentional blink (AB) is thought to be the result of capacity limitations in visual information processing. Neuropsychological and neuroimaging evidence implicated the right hemisphere as the source of this…

Although the role of memory in visual search is debatable, most researchers agree with a limited-capacity model of memory in visual search. The authors demonstrate the role of memory by replicating previous findings showing that visual search is biased away from old items (previously examined items) and toward new items (nonexamined items).…

Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being…

In this article, we detail how to produce two inexpensive micromanipulators that offer high precision (approximately 25 micrometers) along a single axis of movement. The more expensive of the designs provides improved versatility along multiple axes. Both manipulators offer substantial savings over commercially available micromanipulators with…

The author uses the example of a text a student was not allowed to display on his course Web site to explore how and why institutional ideologies particular to the historical development of composition and creative writing--especially when viewed in conjunction with current copyright law--render students' multimedia compositions illegitimate. He…

This article outlines two compatible models of planning and implementing programs for students with autism spectrum disorders (ASD). The Ziggurat Model begins the process with an assessment of student strengths and concerns related specifically to ASD and identifies interventions across five tiers that match these strengths and concerns: (a)…

Images express meaning through particular configurations of visual concepts. A distinguishing feature of discipline based art education is the use of visual imagery to transmit meaning to students. Discipline based art education incorporates concepts and skills from aesthetics, art criticism, art history, and art production and presents a unique…

Explains the hierarchic structure of the mammalian visual system. Proposes a model in which feedback pathways serve to modify sensory stimuli in ways that enhance and complete sensory input patterns. Investigates the functioning of the system through computer simulations. (ML)
