A Fraser illusion without local cues?
In the well-known Fraser illusion, a line composed of tilted elements itself appears tilted. The standard explanation of this illusion has been that the global orientation of the line is in some way influenced by the local orientation of the elements. The illusion was recreated using a texture composed of collinear Gabor stimuli, which were vertical. There was no local tilt. The illusory tilt w...
متن کاملThe neural signature of the Fraser illusion: an explorative EEG study on Fraser-like displays
We studied neural correlates accompanying the Fraser spiral illusion. The Fraser spiral illusion consists of twisted cords superimposed on a patchwork background arranged in concentric circles, which is typically perceived as a spiral. We tested four displays: the Fraser spiral illusion and three variants derived from it by orthogonally combining featural properties. In our stimuli, the shape o...
متن کاملThe perception of depth in simple figures.
When subjects with good stereoscopic acuity are given the task of judging which of two vertical lines lies nearer, the presence of other features nearby alters the perceived depth within the test pair. In the presence of a single flanking line shown with disparity, the test line pair is seen as fronto-parallel when it has disparity in the direction which tends to align it in depth with the flan...
متن کاملGeneration System that Uses Simple Rhetorical Figures ∗
This paper describes the improvement of the stylistic quality of the texts generated by the PRINCE system, a natural language generation application designed for building texts for simple fairy tales. This is done by exploiting the potential of a lexical resource such as WordNet and structure mapping algorithms to enhance the output texts with simple rhetorical tropes such as metaphor and analo...
متن کاملJudging spatial properties of simple figures
Discrimination was measured for height, area, and aspect ratio of ovals and rectangles. Random jittering of the orthogonal property (width, aspect ratio, and area) was used to control the observers' criterion. Weber fractions for aspect ratio were consistently lower than those for area, and about the same as those for height. Performance with ovals and rectangles did not differ significantly. T...
