Perception Flashcards
Relative size
How large an object appears in an image
Height in plane
How high the object appears in the image
Occlusion
When one object seems to cover part of another object
Linear perspective
When straight lines are angled so
that they would come together at a point on the horizon
Convergence
eyes point closer together when an
object is close. Muscles work
harder so know distance and
depth
Retinal disparity
difference between the view of the left and right eye gives the brain
information about depth
Sensation
the information we receive through our senses
Perception
how we interpret or make sense of the sensory information that we receive
Culture
The way we are brought up can influence our perception. Hudson research showed that children from tribal cultures interpreted the depth of an image showing a hunter, antelope and elephant differently
Emotion
Our moods can affect how
we perceive. Children who are excited about Christmas time drew
pictures of Santa bigger and
with more presents than
they did after Christmas and
the excitement has gone.
Upset people notice more
upsetting events and
actions
Monocular depth cues
A way of detecting depth
or distance which works
with just one eye.
Binocular depth cues
A way of detecting depth or distance, which requires two eyes in order to work. Using binocular depth cues allows us to be much more accurate in our judgement of depth.
