Midterm Flashcards
The eye and brain break up the visual world into various aspects such as…
color, form, motion and depth
Eyes take in what
the stimuli. The brain makes sense of it.
Vision is
1 tenth physical and 9 tenths mental
Perception is what
limited and selective. We detect only a slim portion of the information around us. What we decide to see is determined by what we know, believe and want.
Perception definition
the process of acquiring, interpreting, selecting and organizing sensory information.
Visual Perception
Gathering information through sight, organizing and making sense of it.
2 parts of Perception
- Making sense of it (tasks and mental shortcuts)
2. Judging what to focus on (selecting objects)
Western countries focus on what
objects
Eastern countries focus on
the spaces between objects
Japan: the ma
the intervening interval
7 visual communication theories
gestalt semiotics constructivism ecological Theory Cognitive Theory Huxley/Lester Model Omniphasism
Gestalt
The whole is greater than than the sum of its parts. Perceive parts/objects as whole. Primary, kicks in first. Form-forming capability of our senses. Grouping.
Grouping
Creates visual cohesion
Grouping similarity takes into account what 4 aspects?
size, value, color, and shape
Grouping proximity
Dominate all other grouping concepts. Spacial nearness.
Grouping closure
Pleasing to the brain. Fill in missing information to form an unfinished object.
Grouping continuity
Brain tends to form lines, follow what it perceives to be a path.
Grouping figure-ground contrast
differentiation between the object and the background.
Philosophers associated with Gestalt theory
Max Wertheimer- formal gestalt theory
Rudolf Arnheim- applied gestalt theory to interpretation of the visual arts. Also have to worry about the quality of the individual elements as well as the whole.
Semiotics
The science of signs. A symbol (something that stands for something else)
C.S. Peirce
Semiotic theory expert, “we think only in signs.”
Ferdinand de Suassure
Semiotic theory expert, “signs are divided into 2 parts.”
- signifier
- signified
Icon
resemblance. looks like or resembles what it stands for.
Index
cause and effect. Logically connected, can make sense of it.
Symbol
convention, have to be taught it, no logical connection.
Constructivism
Relating patterns of shape, visually arranging planes together. (Saccadic jumps our eyes make)
Ecological Theory
Take into account the environment/real world setting. Lighting, depth, scale, etc. contribute to the visual communication.
Cognitive Theory
Based on process in the brain like memory and comparison. Brain will seek out what is familiar based on experiences/memories that you already have. Went beyond the stimulus and made the best guess.
Huxley-Lester Model
The more you know, the more you see. Sight and thought are inseparable. “Images have no use if the viewer’s mind doesn’t use them.”
Stages of Huxley-Lester Model
-Sensation
-Selection
-Perception
sensing + slecting + percieving =seeing
Omniphasism
“All in balance.” Balancing the two primary cognitive systems: the rational and intuitive.
Paleolithic man paints in cave walls (when and where)
25,000 BC Lascaux
Cave iconography centers on 3 themes
- Animals (dominant images, scary animals are not shown as often)
- Humans (people are not drawn as well as animals, stick figures)
- Signs (often associated with animals)
Cussac cave
Found in France, mostly etching, birds are present, sexual icons lots of bison and people.
Catal Huyuk mural 6200 BC
Neolithic portrayal of active volcano
Written language
Began in Africa created ideograms, then Sumerian clay tablets, then Egyptian hieroglyphics
ideograms
pictures representing words
Rosetta Stone
Had three different languages:
- Egyption hieroglyphics
- Egyption Demotic
- Greek
David Diringer: 4 historical stages of writing
- Iconography
- Synthetic or Ideographic writing
- Analytic or Transition Writing
- Phonetic
Synthetic or Ideographic writing
pictures used to tell a story, poem or epic, used to call something to mind
Iconography
picture writing (cave drawings)
Analytic or Transition Writing
picture becomes an accepted symbol of its name
Phonetic
symbols representing oral sounds
