Perceptual tasks such as object matching, mammogram interpretation, mental rotation, and satellite imagery change detection often require the assignment of correspondences to fuse information across views. We apply techniques developed for machine translation to the gaze data recorded from a complex perceptual matching task modeled after…

In a glance, the visual system can provide a summary of some kinds of information about objects in a scene. We explore how summary information about "orientation" is extracted and find that some representations of orientation are privileged over others. Participants judged the average orientation of either a set of 6 bars or 6 circular…

The purpose of this study was to compare the cognitive processing profiles of school-age children (ages 7 to 17) who met criteria for underachievement in oral reading accuracy based on three different methods: 1) use of a regression-based IQ-achievement discrepancy only (REGonly), 2) use of a low-achievement cutoff only (LAonly), and 3) use of a…

Several seconds of adaptation to a flickered stimulus causes a subsequent brief static stimulus to appear longer in duration. Nonsensory factors, such as increased arousal and attention, have been thought to mediate this flicker-based temporal-dilation aftereffect. In this study, we provide evidence that adaptation of low-level cortical visual…

Formal algebras are among the most powerful and general mechanisms for expressing quantitative relational statements; yet, even university engineering students, who are relatively proficient with algebraic manipulation, struggle with and often fail to correctly deploy basic aspects of algebraic notation (Clement, 1982). In the cognitive tradition,…

This article presents three case studies that explore a very popular trend in art museum adult education in the last decade--partnerships with medical schools to offer critical professional development in visual observation. Each case study describes a critical perspective in the development and implementation of this programming trend: that of…

Color and intensity coding provide perceptual cues to segregate categories of objects within a visual display, allowing operators to search more efficiently for needed information. Even within a perceptually distinct subset of display elements, however, it may often be useful to prioritize items representing urgent or task-critical information.…

From her first encounter with stereoscopic 3D technology designed for classroom instruction, Megan Timme, principal at Hamilton Park Pacesetter Magnet School in Dallas, sensed it could be transformative. Last spring, when she began pilot-testing 3D content in her third-, fourth- and fifth-grade classrooms, Timme wasn't disappointed. Students…

The Wechsler Abbreviated Scale of Intelligence (WASI; Psychological Corporation, 1999) and the Wide Range Intelligence Test (WRIT; Glutting, Adams, & Sheslow, 2000) are two well-normed brief measures of general intelligence with subtests purportedly assessing verbal-crystallized abilities and nonverbal-fluid-visual abilities. With a sample of…

A LONGITUDINAL STUDY WAS PERFORMED WHICH FOLLOWED THREE GROUPS OF CHILDREN (CULTURALLY DISADVANTAGED, AVERAGE, AND CULTURALLY ADVANTAGED) THROUGH GRADE THREE IN AN ATTEMPT TO DETERMINE THE RELATIVE IMPORTANCE OF THE DEVELOPMENT OF CERTAIN PERCEPTUAL FACTORS ON SUCCESS OR FAILURE IN BEGINNING READING. INSTRUMENTS USED WERE SELECTED TO IDENTIFY…

A METHODOLOGICAL STUDY WAS CONDUCTED WHICH HAD AS ITS PRINCIPAL OBJECTIVES--(1) DEVELOPMENT OF A RELATIVELY SIMPLE, EFFECTIVE, AND ECONOMICAL WAY TO EVALUATE SPECIFIC (TELEVISION) VISUAL TECHNIQUES, AND (2) TEST THE METHOD IN A VARIETY OF SITUATIONS. A TWO CAMERA CLOSED-CIRCUIT TELEVISION SYSTEM WAS MODIFIED SO THAT THE OUTPUT OF THE TWO CAMERAS…

THIS STUDY REPORTS THE FIRST PHASE OF A 5-YEAR LONGITUDINAL INVESTIGATION OF THE COMPARATIVE EFFECTIVENESS OF A HIGHLY STRUCTURED PRESCHOOL PROGRAM AND A TRADITIONAL NURSERY SCHOOL PROGRAM IN AMELIORATING THE LEARNING DEFECTS OF CULTURALLY DISADVANTAGED CHILDREN. THE HIGHLY STRUCTURED PROGRAM IS INTENDED TO OVERCOME PARTICULAR WEAKNESSES OF…

This assessment guide represents a method for evaluating visual arts achievement by third graders. The artwork presented can be used to determine whether students have met learning objectives and are ready to advance, and also as a diagnostic tool for school improvement. The guide is based on selected sample learning objectives from "State…
