The purpose of the present research is to develop a visual-spatial ability test (VSAT) for primary school children. Visual-spatial abilities allow processing of information about an object in terms of shape, colour, texture, perspective, and rotation. The visual-spatial test includes items-tasks for the participants to process information about…

It is generally assumed that children with intellectual disabilities (ID) have an increased risk of impaired visual information processing due to brain damage or brain development disorder. So far little evidence has been presented to support this assumption. Abnormal visual orienting behavior is a sensitive tool to evaluate impaired visual…

To identify the most important competencies for college graduates to succeed in the 21st century workforce, we conducted an analysis of the Occupational Information Network (O*NET) database. O*NET is a large job analysis operated and maintained by the U.S. Department of Labor. We specifically analyzed ratings of the importance of abilities (52…

This paper reviewed briefly the major types of masking effects obtained with various methods and the major theories or models that have been proposed to account for these effects, and outlined a three-mechanism model of visual pattern masking based on psychophysical and neurophysiological properties of the visual system.

Two important processes in the acquisition of visually presented information are the ability to maintain discrete perceptual events as separate in time and the ability to abstract information from brief exposures. Five phenomena were measured which appear to reflect these abilities. Critical Flicker Frequency (CFF) is the intermittency rate at…

In contemporary reading comprehension tests, abilities which may have little to do with reading ability can have a great effect on test scores. Reading tests are not constructed so that they maximize abilities unique to reading. On the other hand, tests on other language skills do not minimize what is unique to reading. Comprehension is the…
