Exam 3 PSYC 230 UIUC UPDATED
ACTUAL Questions and CORRECT
Answers
Object Agnosia - CORRECT ANSWER -Inability to recognize objects using only vision
- Lack ability to label object, but can identify features of object (red, circular, etc..)
- Can tell you color, shape, etc..
Bottom Up Processing - CORRECT ANSWER -Physical properties of a stimulus
influence how we perceive them
- Light -> eyes -> ganglion cells -> visual cortex
- STIMULUS-driven
Top Down Processing - CORRECT ANSWER -Existing knowledge of objects influences
how we perceive them
- EXPERIENCE-driven
Recognition - CORRECT ANSWER -Ability to match an item with something from
memory
Representation - CORRECT ANSWER -Storage/Reconstruction of information in
memory
Grouping - CORRECT ANSWER -the perceptual tendency to organize stimuli into
coherent groups
Segregation - CORRECT ANSWER -Top-down knowledge used to pick apart a scene
(separate white chairs from white table)
, Bottom-Up knowledge: Visual cues tell us where things are in relation to others, what things are
in a scene
Gestalt Psychology - CORRECT ANSWER -a psychological approach that emphasizes
that we often perceive the whole rather than the sum of the parts
- Whole is greater than the sum of its parts
Perceptual Organization - CORRECT ANSWER -the process of grouping and segregating
features to create whole objects organized in meaningful ways
figure-ground perception - CORRECT ANSWER -the ability to discriminate properly
between a figure and its background
- Affected by symmetry, convexity
Law of symmetry - CORRECT ANSWER -the gestalt grouping law that states that
elements that are symmetrical to each other tend to be perceived as a unified group
- Because many of the objects in the world are symmetrical, so an object that has an edge on one
side, there is probably an edge on the other side
- Affects figure ground interpretation
- Perceive things not in symmetrical brackets as background
Convexity in gestalt psychology - CORRECT ANSWER -More likely to perceive less
convex things as figure, not ground
Law of good continuation - CORRECT ANSWER -lines tend to be seen as following the
smoothest path n
Law of proximity - CORRECT ANSWER -elements close to one another tend to be
perceived as a unit
