What are the three levels of complexity in perception? Primary cortex, secondary association cortex, and tertiary association cortex.  
What is the function of the primary cortex? Direct processing sensory and motor functions, see and feel object.  
What is the function of the secondary association cortex? First level of processing, name the object by sight or feel.  
What is the function of the tertiary association cortex? Complex integration, attach meaning, memories, or emotions to objects.  
What are the perceptual functions associated with the frontal lobe? Appropriate expression of emotions, combining/interpreting sensations, generating behavior patterns.  
What are the perceptual functions associated with the temporal and limbic lobes? Development of emotional states, memory of identification and meaning, processes communication, sense of humor.  
What are the perceptual functions associated with the parietal lobe? Spatial orientation, body scheme and image, logical ordering/temporal sequencing, development of abstract and symbolic reasoning (math and language).  
What are the perceptual functions associated with the occipital lobe? Integration and interpretation of visual info, perception of visual object spatial relations.  
What are the functions associated with the left hemisphere? Verbal, comprehension, control of right hand, hearing, academics, sequential, temporal, logic, analytical.  
What are the functions associated with the right hemisphere? Facial recognition, dimensional world relationships, non-verbal, visual spatial patterns/relationships, gestalt/total concept, singing and music, intuition, processing of emotional info.  
What are the visuospatial skills? Figure ground, position in space, spatial relations, visual memory, topographical orientation.  
Define figure ground. Ability to differentiate foreground from background, area separate from a larger field.  
How would you test figure ground? Have a patient find a certain city or town on the map.  
Define position in space. Correct interpretation of positional descriptions.  
Define spatial relations. Ability to differentiate self from objects in space as well as relate objects in space with each other.  
How would you test spatial relations? Two dimensional: patients copy drawings, three dimensional: obstacle course.  
Define visual memory. Ability to recall spatial info.  
Define topographical orientation. Able to find one’s way from one place to another.
