seeing form & recognition Flashcards
what are the laws of perceptual organisation
gestalt psych; explains the rules for recognising form
law of pragnanz
stimulus is seen as the simplest structure it can be
law of similarity
similar things group together in shape or colour
law of proximity
close items group together
law of good continuation
points of straight or smooth lines belong together
law of closure
we tend to perceive objects as complete despite occlusion
law of common fate
grouping by motion; if things move together, they belong together
law of meaningfulness
items form groups if these groups are meaningful or familiar
what are these laws in terms of learning
HEURISTIC
figure-ground segregation
border belongs to the figure: within continuous closed boundary symmetry smaller items lower portion meaningful shapes
predictive processing
top down predictions from experience used to either confirm or reject incoming sensory data
modular view of object recognition
specialised brain areas detect and represent certain objects like faces/buildings
= relatively encapsulated functions
object recognition: distributed representation
recognition occurs across multiple brain areas which work together
parts-based object recognition
brain deconstructs objects into a collection of parts, creating an inventory of geometric elements
Bruce & Young’s model of facial recognition
different levels are involved in recognising faces [structural encoding] from features to nuanced expression
