PERCEPTION & CONGNTION (Object Recognition Theories Top-Down…

- - - - Akinetopsia:
        Motion perception impaired
        
        damage earlier in V1
    - - Prosopagnosia:
        deficit in recognizing faces
        
        Damage in Fusiform Face Area
        
        Diff forms:
        
        Apperceptive/Perceptually-Based: problem perceiving faces (contorted look)
        
        Associative/Meaning-based: problem attaching meaning to faces (cannot be identified)
        
        Diff causes:
        
        Acquired (brain injury)
        
        Congenital (genetic)
      - Visual Agnosia:
        deficit recognizing objects
        
        Apperceptive Visual Agnosia:
        
        problem perceiving object
        
        can detect visual features
        
        cannot copy simple line drawing
        
        Associative Visual Agnosia:
        
        problem attaching meaning to objects
        
        cannot draw objects from memory
        
        cannot name objects
        
        cannot match function to objects
        
        cannot tell if an impossible object/animal exists or not
      - Achromatopsia:
        deficit in perceiving colors
        
        damage earlier in V1
- - - - Blindsight:
        
        damage to V1
        
        perceive things without knowing it = implicit perception
        
        Test with lights on/off
      - Subliminal Priming:
        
        Backward masking Experiment with congruent/incongruent patch --> target was processed even below awareness
- - - - Middle Level = Cognitive Demons
        
        detect particular patterns of features
        
        if detected, demons SHOUT
      - Top Level = Decision Demons
        
        selects the 'loudest' cognitive demon to identify an object
      - Bottom Level = Data/Feature Demon
        
        individual features are represented
