| What is the name of the integration process of visual input within the CNS? | Visual Perception |
| If oculomotor control, visual fields, and visual acuity are at the bottom of the visual perceptual heirarchy, and support the next visual perceptual ability, what is the ability the named three visual perceptual skills support? | Attention |
| What does "attention" support in the visual perceptual heirarchy? | Scanning |
| What is "scanning" required for? | Pattern recognition |
| What does "pattern recognition" involve identification of? | Features of objects |
| If "pattern recognition" gives way for "visual memory" and "visual memory" gives way for "visuocognition", what is the highest visual perceptual ability in the hierarchy and which comes only after "visuocognition?" | Adaptation through vision |
| What are three Visual Foundation Skills of visual perception? | Acuity, Visual Fields, and Oculomotor Function |
| What is the ability of the eyes to move smoothly and with coordination through full range of motion called? | Ocular Motility |
| Ocular Motor Dysfunction includes the following areas: Eye Alignment, Convergence, Accommodation, Visual Tracking, and ______? | Saccades |
| In OT Binocular Vision Treatment, the procedure for Partial Occlusion is to add opaque material to the client's glasses in order to block input to the client's central visual field yet leave client's peripheral field unobstructed. What is the goal? | Goal is to reduce occluded area as the muscles get stronger. |
| With Binocular Vision Treatment, the OT performing Total Occlusion with a client will want to (a) only perform when truly necessary, and (b) alternate occlusion between eyes every _____(time measurement). | hour |
| Agnosia is the inability to recognize ______ and often occurs as in conjunction with a lesion in the R occipital lobe. | objects |
| A cliet with deficits in the ability to determine his or her position in space (the ability to understand the concepts of over/under, above/below) will have difficulty with what occupations? | Difficulty moving in a crowded area, difficulty following directions using those terms, and difficulty dressing. |
| If a client is unable to find an object in a cluttered drawer, the brakes on a wheelchair, and white on white, what visual-spatial skill might be affected? | Figure ground: Ability to distinguish foreground from background |
| Agnosia is the inability to recognize objects via visual input and often occurs with a lesion to the R/L occipital lobe? | R |
| If a client presents with only onse side of the face shaved, one side of the body dressed, and can be observed to bump into objects on one side, what might the OT suspect? | Unilateral neglect: lost ability to integrate perception of one side of body or environment (usually left) |
| What are the types of Agnosia? | color agnosia, color anomia, metamorphopsia, prosopagnosia, simultagnosia |
