PSYB57H3 Lecture Notes - Lecture 3: Visual Cortex, Outline Of Object Recognition, Visual Hierarchy
Document Summary
Psy270: lecture 3: perception: the act of giving that stimulus meaning. The neuron"s preference for features is located in the primary visual cortex: component shapes: Shapes and movement is recognized by the occipital lobe: early complex shapes: Neurons fire within the primary visual cortex especially when there is a combination of component shapes: genuine complex objects: Neurons fire rate increases drastically when the complexity of a shape or object increases (e. g. Higher levels prefer more complex objects combine features like edges. People are pretty accurate in recognizing objects (80 90% success rate: number of components presented (x vs. y): As the number of geons increases, the reaction time becomes faster: number of components presented x" in object: fewer necessary for recognition. The more geons in an object, the proportionately. Geons cannot differentiate breeds: object recognition is more dependent on viewpoint than predicted by recognition by component, hypothesis:
