Pattern Recognition
• E. Gibson’s Feature Theory» Complex stimuli are composed of distinctive and separable parts
called features.
» Pattern recognition is accomplished by counting the presence or absence of a checklist of features.
» Gibson’s specification of the feature set◊ Features must be critical
◊ Identity should be unchanged by brightness, size and perspective.
