The bright pigments of cave pictures in Spain have been preserved from Paeleolithic times by the accidental formation of a surface film of calcite (Kuhn, 1952), and since then many glazes have been used deliberately for the protection of colours. The idea of varnishing glass slides is not novel, but practical difficulties concerning preparation, pH, and especially viscosity, have discouraged it...

The watercolor illusion is a long-range color assimilation (coloration effect) imparting a figure-ground segregation (figural effect) across large enclosed areas (B. Pinna, 1987; B. Pinna, G. Brelstaff, & L. Spillmann, 2001; B. Pinna, L. Spillmann, & J. S. Werner, 2003; B. Pinna, J. S. Werner, & L. Spillmann, 2003). The watercolored figure has a very poorly reversible or univocal figure-ground ...

A neuron can respond to periodic inhibitory input with a variety of complex behaviors, periodic and aperiodic. We present a succession of models to test hypotheses for mechanisms underlying complex behavior generation. Model comparison using non-linear dynamics techniques indicates that long-duration IPSP aftereffects and spiking behavior are necessary for most of the basic response properties,...

Humans have an impressive ability to discriminate between faces despite their similarity as visual patterns. This expertise relies on configural coding of spatial relations between face features and/or holistic coding of overall facial structure. These expert face-coding mechanisms appear to be engaged most effectively by upright faces, with inverted faces engaging primarily feature-coding mech...

Figural aftereffects are commonly believed to be transient and to fade away in the course of milliseconds. We tested face aftereffects using familiar faces and found sustained effects lasting up to 1 week. In 3 experiments, participants were first exposed to distorted pictures of famous persons and then had to select the veridical face in a 2-alternative forced choice task. Veridicality afteref...

Este artigo examina de que modo o conceito figural, segundo desenvolvimento dado por Jean-François Lyotard, está presente na teoria contemporânea do cinema. A partir uma recapitulação sintética da conceituação figural feita Lyotard obra Discours, figure (1973), descreve como se configura interesse Jacques Aumont possibilidade imagem pensar; Nicole Brenez autonomia em relação à realidade; Philip...

Background Key to optimizing Computational Thinking (CT) instruction is a precise understanding of the underlying cognitive skills. Román-González et al. (2017) reported unique contributions spatial abilities and reasoning, whereas arithmetic was not significantly related CT. Disentangling influence numerical skills on CT important, as neither should be viewed monolithic traits.Objective This s...

Abstract This study identified the provenance of Pb flux used in production glaze unique, high‐quality late medieval stove tiles from northern part Carpathian Basin, and elaborated evaluated a fast preparation process to measure isotope ratios high‐Pb glazes. We compared three different methods preparation. Method 1 consisted dissolution bulk chips glaze, dilution solution mass spectrometric an...

The distribution of figural "goodness" in 2 mental shape spaces, the space of triangles and the space of quadrilaterals, was examined. In Experiment 1, participants were asked to rate the typicality of visually presented triangles and quadrilaterals (perceptual task). In Experiment 2, participants were asked to draw triangles and quadrilaterals by hand (production task). The rated typicality of...
