Analogical reasoning, the ability to learn about novel phenomena by relating it to structurally similar knowledge, develops with great variability in children. Furthermore, the development of analogical reasoning coincides with greater working memory efficiency and increasing knowledge of the entities and relations present in analogy problems. In figural matrices, a classical form of analogical...

In an effect we call color from motion (CFM), apparent motion is accompanied by subjective color spread seen in physically achromatic regions. Here we report that physical lights can cancel the subjective color seen in CFM. As measured by cancellation, the saturation of the subjective color spread increases as the luminance of the test elements increase. Without luminance differences between te...

Cognitive impairment is as an important feature of Multiple Sclerosis (MS), and might be even more relevant to patients than mobility restrictions. Compared to the multitude of studies investigating memory deficits or basic cognitive slowing, executive dysfunction is a rarely studied cognitive domain in MS, and its neural correlates remain largely unexplored. Even rarer are topological studies ...

In this paper, I begin by suggesting digital photographic images should be considered as being neither a purely visual experience nor a purely perceptual one. Instead, I argue these may be somewhat limiting terms which confine our engagement with images to traditional linguistic interpretations. At a time when digital images are more amenable and liable to forms of recombination, fragmentation ...

A key goal of visual processing is to develop an understanding of the three-dimensional layout of the objects in our immediate vicinity from the variety of incomplete and noisy depth cues available to the eyes. Binocular disparity is one of the dominant depth cues, but it is often sparse, being definable only at the edges of uniform surface regions, and visually resolvable only where the edges ...

Abstract Chemical compositional data sets of archaeological artefacts are often analysed using standard statistical procedures. Adopting a different approach, we examine the major element oxides found in Parthian and Sasanian glazed pottery by identifying statistically important ratios conjunction with expert knowledge scientist during, rather than after, identification process. This results me...

Samples of northern porcelain wares dating to between the 6th and 13th centuries from three most important Chinese ceramic kiln sites, Gongyi, Xing Ding have been studied in this work. The Sr isotope chemical compositions glazes these determined. Based on scientific results we able suggest raw materials used make glazes. Using Strontium isotopic analysis successfully shown that earliest use lim...

We have investigated the apparent collapse of stereopsis obtained with random-dot-stereograms at isoluminance. Contrast thresholds for both depth and form discrimination of targets in random-dot- and figural stereograms were measured at a number of disparitics, using both isoluminant and isochromatic stimuli. All contrast thresholds for stereoscopic tasks were normalised to contrast thresholds ...

To address the paucity of current research on the development of creativity in deaf students, and to extend existing research to adolescents, the present study investigated divergent thinking, a method of assessing creativity, in both deaf and hearing adolescents. We assessed divergent thinking in two domains, figural and verbal, while also adjusting the instructional method in written format, ...
