5 - Visual Art Flashcards
pictures
are 2D but have sense of
- implied motion (sense im of movement)
- implied depth (looking like 3D)
-> snapshot of motion, action and emotion (freeze frame) (this also holds for statues)
different parts of brain for object identification and location
two cortical pathways:
- vision
- spatial vision
what -> object identification (shape) -> temporal lobe, ventral stream -> static aspects
where -> object location and motion (layout) -> parietal lobe, dorsal stream -> dynamic aspects
modules in the central stream (for objects)
- fusi form face area -> just responds to faces
- extrastriate body area -> respond to bodies
What - ventral system (objects) / in depth
= static aspect of pictures
- object recognition
- shape recognition
- color perception
where - dorsal stream (spaces) / in depth
= dynamic aspect of pictures
- overall spatial layout
- implied depth
- implied motion/emotion
visually guided action
involves how pathway; in motor cortex
-> perception for action pathways
(when sensory guidance is needed all 3 pathways are needed (the drawing system))
dynamic processes vs static objects
production vs perception
instrumental gestures vs emanation (visual motion)
origin of visual arts
- started with geometrics (patterns)
- went on to figuratives (of known things)
mark making
earliest findings are zic zac patterns = parallel lines = geometrics
-> rock art (reasons for doing it unknown)
visual system primitives (different theories of why such geometric drawings arose)
geometrical patterns are intrinsic to the visual system (encoded in brain, natural)
-> first drawings might just be a resonance of ongoings in brain
hallucinations (drug use)
-> maybe people transformed their trips to paintings (people usually see geometric patterns)
phosphene theory
-> seeing light when hitting head even though there is none
scribbles (known from kids)
-> motor cortex system -> all three systems
axes of limbs movement (way we organize movement in motor system -> way we use tools)
-> kids start with linear lines, then patterns (circular; needs coordination) and then combine it all (allows for more abstract paintings) -> simple geometric forms can build complex patterns
Geometrics as building blocks
- the earliest human rick art
- object recognition (recognition by components - see basic building blocks)
- form and ornamentation of human-made objects (visual rhythms to make objects special)
- architectural and interior design (lots of geometrical forms combined; human made (not found in nature))
- notation systems (alphabet and music notes made of geometric forms)
- configurations if human social interactions (we organize our patterns geometrically as well)
imitative arts
(Plato and Aristotle)
- painting is an object with the function to represent other objects
- not trying to have pictorial realism
- selective re-creation if reality
visual arts vs dance/ theater
static form of storytelling vs dynamic form
photographs are iconic, theater is mainly arbitrary
2D:multi panel images
several images telling a story
origins of figurative art
- memory; drawing from memory representation in brain
- tracing; generate figurative image by ex. drawing around hand on paper
- copying; model in front of you
