Presentation Transcript

  1. Art and perceptual expertise

  2. Structure • Applying principles of perception to art-making • Why study representational drawing? • How to quantify drawing ability • Research connecting drawing ability and various perceptual phenomena

  3. Structure • Applying principles of perception to art-making • Why study representational drawing? • How to quantify drawing ability • Research connecting drawing ability and various perceptual phenomena

  4. John Ruskin: The Innocent Eye The whole technical power of painting depends on our recovery of what may be called the innocence of the eye; that is to say, of a sort of childish perception of these flat stains of colour, merely as such, without consciousness of what they might signify John Ruskin Art-making is returning to a ‘sensory core’ Seeing through schematic biases

  5. Gibson – Direct Perception • Sensation is perception • Phenomena like optic flow give unambiguous evidence about the visual qualities of the environment

  6. Mark Tansey ‘The Innocent Eye Test’

  7. Ernst Gombrich: Schemata The artists’ dilemma: That of conjuring up a convincing image despite the fact that not one individual shade corresponds to what we call 'reality’ Ernst Gombrich Art-making is solving the inverse problem of vision

  8. Gregory – Generative Perception • Perception as hypothesis testing • Unconscious inferences from sensory data(Von Helmholtz) • Formation of incorrect hypotheses lead to errors in perception (and artistic effects!)

  9. See through or seeing with schemata? • Artistic schemata - attention and selection of features sufficient for depiction in a particular medium • The sets of cues necessary for adequate depiction are culturally specific and not fixed

  10. Art as caricature Average Stimulus Caricature

  11. Rudolf Arnheim: Evolution of representation Children perceive the universal more readily than the particular In the field of art – and this is probably true also for the psychology of thinking – highly abstract forms appear at the most primitive stages Rudolf Arnheim Leo, Aged 2½ 

  12. Abstraction

  13. Structure • Applying principles of perception to art-making • Why study representational drawing? • How to quantify drawing ability • Research connecting drawing ability and various perceptual phenomena

  14. Why study drawing? Drawing represents a complex but tractable process Output comparable with original stimulus

  15. Structure • Applying principles of perception to art-making • Why study representational drawing? • How to quantify drawing ability • Research connecting drawing ability and various perceptual phenomena

  16. How do we measure drawing ability? • ‘Because there is no universal computer algorithm for comparing the accuracy of renderings with that being rendered, one must resort to using critics to judge the accuracy of a rendering.’(Cohen, 2005)

  17. How do we measure drawing ability? • Shape Analysis • Determined set of coordinates on an image • Measures shape accuracy but as yet no systematic way of measuring distortion or effects other than shape

  18. Structure • Applying principles of perception to art-making • Why study representational drawing? • How to quantify drawing ability • Research connecting drawing ability and various perceptual phenomena

  26. Drawing and Attention Shifting Attention shifting. Local-global levels of processing GL switch LG switch

  27. A link to visual flexibility? Ambiguity and attention shifts

  28. Art-making is embodied • Perception does not function in isolation • Motor imagery used in patient DF in lieu of visual form recognition • Anticipatory motor planning could be used by expert artists • Changes in holistic processing may be related to sensorimotor experience

  29. Conclusions • Drawing and art-making a process of both seeing through and see with biases in perception • Drawing ability linked to enhancements in perceptual processing, namely: visual selection, visual integration, perceptual constancies, local processing and attention switching • Integrate this into an embodied framework – how does it relate to perceptual/sensorimotor expertise • Chart the development of perceptual and conceptual skills throughout the lifetime of the artist to understand the role of innate ability and training
