14.00 Why Are Paintings Painted as They Are? The Place of Children’s Drawings in Vision and Art
This work explores phenomenologically a new research perspective, whose purpose is to answer the question ‘why are paintings painted as they are?’. This perspective is based on the pictorial repro- duction task aimed to reveal how subjects of different ages copy/paint what they perceived and how they organize the visual raw material. The results demonstrated the emergence of visual singularities organized in at least four stages going from 4 to 18 years of age reflecting different artistic styles and accomplishments appeared during the history of art. These outcomes entail that the answer to the previous basic question is: ‘we paint what and the way we paint because we perceive what and the way we perceive’ (painting–perception coupling). On the basis of these results, it is suggested that children’s drawings can significantly contribute to the comprehension and explanation of the painting–perception coupling.
16.00 The syntax organization of shape and color and the laws of coloration in vision, art and biology
In this work we demonstrated that next to the figure-ground segregation and the perceptual grouping, as proposed by Gestalt psychologists, there is a further and more complex kind of organization related to the way object attributes like shape and color are organized to create a visual object. More particularly, through new logical and phenomenal implications, we explored the complexity of the phenomenal coloration and the syntactic relation between shape and color. Moreover, we extracted the main laws ruling their phenomenal logic and organization. Finally, we presented new conditions and a new paradigm based on the drawings and paintings made spontaneously by children of different ages in a drawing/painting task. Through this paradigm, it was assumed that the way children organize shape and color in their drawings and paintings are related to the way the visual system perceives their syntactic relation.
The results showed that, under the conditions studied, shape and color are organized as juxtaposed and in sequential order with the shape that becomes hierarchically the core reference for the color. The results suggest a visual syntactic organization as a new kind of object formation process useful to understand the language of vision and the implications for art and biology.

17.00 From Kandinsky's paintings to the watercolour illusion: A new theory of color filling-in
The watercolour illusion (WCI) is a long-range assimilative spread of colour (filling-in) emanating from a thin coloured line running contiguous to a darker chromatic contour. Kandinsky's paintings show examples of filling-in related to the WCI. Filling-in reveals the dissociation between the retinal input and the percept, and raises fundamental questions about brain activities. Here, I describe experiments, based on the WCI and Kandinsky's insights, by examining the psychophysical conditions, the main laws and possible neural mechanisms associated with this remarkable phenomenon.
