Chapter 3 (Perception) Flashcards
you have perceived patterns, objects, people, and events in the world
perception
objects or events to perceive
distal stimulus
reception of information and its registration by a sense organ
proximal stimulus
the image reflected onto the back of the retina
retinal image
meaningful interpretation of the proximal stimulus
percept
the difference of perception vs the retinal image
size constancy
recognition of a particular object as belonging to a class of objects, events
pattern recognition
segregation of the whole display into objects and the background
form perception
means that the perceiver starts with small bits of information from the environment and combines in various ways to form a percept
bottom-up processing
the perceivers expactions, theories, or concepts guide the selection and combination of the information in the pattern recogntion process
top-down
bottom-up perception models
template matching, feature analysis, prototype matching
every object that we encounter and want to derive meaning from is compared to previously stored pattern or template
template matching
break them down into their components
feature analysis
the model where there are image demons, feature demons, letter demons, and decision demon
pandemonium model
explain perception in terms of matching an input to a stored representation of information, an idealized representation of some object
prototype matching
depicts areas of relative brightness and darkness
primal sketch
viewer uses primal sketch to care 2 1/2-D image
two-and-a-half-dimensional sketch
inability to detect changes to an object or scene when given different views of that scene
change blindness
participants could accurately identify letters presented in the context of words than non words
word superiority effect
when readers are more like to miss a letter in some types of words
missing letter efect
describes people as adding to and distoring information in the proximal stimulus to obtain a percept
constructivist approach to perception
believe that the perceiver does very little work in perception
direct perception
the acts or behaviours permitted by ojects places, and events
affordances
impairments in the ability to interpret visual information
visual agnosia
can see contours of a drawing or object but have a very difficult time matching one object with another
apperceptive agnosia
can match objects, but tend to do so very slowly
associative agnosia
specific visual agnosia for faces
prosopagnosia
have explicit face recognition, but impaired implicit facial recognition
capgras syndrome
