module 4 Flashcards
is the ability to see and interpret (analyze
and give meaning to) the visual information that surrounds us.
Visual perception
It can be described as the way the brain interprets what
the eyes see.
visual perception
receives information from the
retina, then using a _________ processes this information using different
parts of the brain e.g. _____ and the ____ and _____ visual cortex of the brain.
- Brain
- hierarchical method
- lateral geniculate nucleus
- primary
- secondary
This can be altered by previous experiences.
The Chairs theory
It can effect the way you see a situation.
The Taxi theory
It is used in media to make you have the opinion of someone that they want you to have.
The Bad guys/good guys theory
seen as the founder of visual perception studies believed vision was a form o f
unconscious inference, Inference is the act or process ofderiving a conclusion based solely on what one already knows)
Hermann Von Helmholtz
Black spots will seem
to appear very quickly at the intersections.
The Scintillating grid illusion
- Focus on the black
dot and move your head back and forth - This creates the illusion that two circles are moving
Optical illusion
The ability to notice detail differences such as shape, size, color, or other dimensional aspects.
Visual Discrimination
The ability to perceive positional aspect differences and recognize objects when they are in a different orientation or format.
Form Constancy (Form Discrimination)
The ability to focus on a selected target and screen out or ignore irrelevant images.
Figure Ground (Foreground-Background Differentiation)
The ability to recognize the positioning of objects in space.
Spatial Relations
The ability to recognize an object, letter or number without seeing all of the object.
Visual Closure
The ability to see objects in a particular sequential order.
Visual Sequencing
The ability to remember forms (letters) and sequences of forms (words) and recognize them quickly when seen again.
Visual Memory
Gestalt Theory
The principle can be split into 3 groups
- Figure and Ground
- Similarity, Proximity, Common Fate & Continuity
- Closure, Area &Symmetry
When we have similar objects of size, shape and colour again we form groups.
Similarity
When objects which are closer to each other we tend to associate them together to form groups.
Proximity
Objects which are facing the same direction or appear to be travelling in the same direction are usually grouped together.
Common Fate
Seeing things as a whole isimportant however seeing in a whole is not necessarily what we are meant to see.
CONTINUITY
If we have a large pattern with missing components we tend to fill in the missing parts to create the image we actually see
CLOSURE
This principle shows us that when areas are overlapping, the smallest area is seen as the figure and the larger is the ground. When we look at this object, we see this as one object on top of the another instead of a hole in the larger area.
AREA
Objects which are symmetrical, we are more likely to group them together.
SYMMETRY
