An acoustic orientation system was developed that employed a portable remote control device keyed to trigger audio tones from modules placed at key locations throughout the user's home and work environments. Results found that the system helped a blind subject to move and work successfully in both settings, and the subject found it easy and…

Describes uses of mathematics in fabric design to examine various cultural and mathematical concepts including patterns, geometric shapes, and spatial reasoning. (ASK)

Provides information about current brain research. Explains that some of the basic tenets that have guided research are outlined in R. Shore's "Rethinking the Brain: New Insights into Early Development." Offers five hypotheses: (1) nature/nurture; (2) effects of nurture; (3) optimal music learning; (4) minimal disadvantages; and (5) early music…

At age 13, students scoring at the top 0.5% in general intelligence completed the Scholastic Assessment Test (SAT), Mathematics and Verbal subtests, and the Differential Aptitude Test (DAT) Space Relations (SR) and Mechanical Reasoning (MR) subtests. It appears that spatial ability assessments can complement contemporary talent search procedures.…

Investigated gender differences in adults' use of route strategy, examining how preferences for landmarks (female) against route directions (male) related to wayfinding behavior, spatial anxiety, and environmental competencies. Participants navigated routes in an unknown building three times and recalled acquired environmental knowledge. Most…

This case study details the history and K-5 school experience of a boy with dyslexia and spatial-temporal gifts. It describes assessment, evaluation, and identification procedures; the learning specialist's interventions and program; the critical role of the parent; and the services provided by the gifted program. Specific interventions are…

Previous research by Lidster and Bremner (1999) on young children's ability to coordinate two dimensions has shown that performance on construction tasks (in which children have to give the correct coordinates for a point in space that is already known) is superior to performance on interpretation tasks (in which children are given a pair of…

Innovation and enterprise depend for their success on the development of new ideas. But from where do new ideas come? How do they arise? Finding solutions to such questions is at the heart of creativity research and the solving of novel problems. Reflection, not only in cognitive processes but also in the non-cognitive ones used in solving novel…

The present study examines the potentially harmful effects of prenatal cocaine exposure on later visuospatial memory functions. A novel neuropsychological measure of immediate- and short-term memory for visuospatial information was administered to 40 children, who were identified as cocaine-exposed, and 11 age and socioeconomic status matched…

Pictorial space can be conceptualized as aggregate space (where figures compete for limited available space) or as axial space (where space is infinite and exists independently of figures). That these two kinds of space concepts follow a developmental sequence was tested by investigating size regulation mechanisms in 7- to 12-year-old children's…

Four experiments examined the flexibility and stability with which children and adults organize locations into categories based on their spatiotemporal experience with locations. Seven-, 9-, 11-year-olds, and adults learned the locations of 20 objects in an open, square box. During learning, participants experienced the locations in four…

The authors investigated whether emotional pictorial stimuli are especially likely to be processed in parafoveal vision. Pairs of emotional and neutral visual scenes were presented parafoveally (2.1[degrees] or 2.5[degrees] of visual angle from a central fixation point) for 150-3,000 ms, followed by an immediate recognition test (500-ms delay).…

Three experiments investigated the route-angularity effect, which is demonstrated when a greater number of turns along a route increases the estimated length. So far, a route-angularity effect has not been demonstrated in school-age children. Because of the lack of a developmental theory, this finding could only be explained by a minor control of…

In two experiments we investigated the automatic adjusting of the attentional focus to simple geometric shapes. The participants performed a visual search task with four stimuli (the target and three distractors) presented always around the fixation point, inside an outlined frame not related to the search task. A cue informed the subject only…

The present studies explored the role of the medial striatum in learning when task contingencies change. Experiment 1 examined whether the medial striatum is involved in place reversal learning. Testing occurred in a modified cross-maze across two consecutive sessions. Injections of the local anesthetic, bupivacaine, into the medial striatum, did…
