Percieving objects and scenes Flashcards
viewpoint invariance
reasons for change in lightness and darkness can be unclear. objects may look different from different angles/shades but we can still recognize them
structuralist view
created by wendt in the late 1800s
perceptions are created by combining sensations
how we see things doesn’t explain how we see apparent movement
spaced circles with lines through them-we see a box
gestalt view
the whole differs from the sum of its parts
perception is not from the sum of its parts but a result of organization
pragnaz - gestalt principals of organization
every stimulus is seen as simply as possible-olympic rings separated
similarity - gestalt principals of organization
similar things are grouped together- different color dots
good continuation - gestalt principals of organization
connect points resulting in straight or smooth curves
figure ground segmentation
deterring what part of a picture is important
vase with faces
which ever we see as the foreground means the background continues behind the forground
RBC recognition by components (structural description models)
only parts are shown but the feature is recognizable
volumetric features make it recognizable
these features are called geons
view invariant properties (properties of geons)
aspects of the object remain visible from different viewpoints
accidental properties (properties of geons)
a property that appears rarely and only from certain viewpoints
discriminability (properties of geons)
ability to distinguish geons from one another
principles of componential recovery (properties of geons)
ability to recognize an object if we can identify its geons
what are the areas of the brain involved with perception and identification
FFA-fusion face area- faces
IT cortex- what the object is presented as
PF cortex- deciding what the object really is
context (perceptual intellegence)
your perception of a given context
- you are given money from a charity even though you have a job- context
- you know its wrong to take this - perception
light from above huristic (perceptual intellegence)
objects are generally perceived that the light is from above based on the fact that that is what we are used to
