Spatial-perceptual deficits are MOST commonly associated with:

1. Left cerebral hemisphere lesion

2. Right cerebral hemisphere lesion

3. Cerebellar disorders

4. Frontal lobe injury

The correct answer is: Right cerebral hemisphere lesion

Spatial-perceptual deficits are primarily associated with lesions in the right cerebral hemisphere. This region of the brain is crucial for processing spatial awareness, visual perception, and the integration of sensory information, which are all necessary for understanding spatial relationships and the environment. Individuals with right hemisphere damage often exhibit difficulties in recognizing faces, interpreting visual information, and navigating through space, which are manifestations of spatial-perceptual deficits. In contrast, lesions in the left cerebral hemisphere typically affect language and analytical skills, leading to deficits that are more cognitive-linguistic rather than spatial. Cerebellar disorders can affect motor coordination and balance but are less connected to spatial perception directly. Frontal lobe injuries may impact executive functions and decision-making but do not primarily cause spatial-perceptual deficits. Therefore, the association of spatial-perceptual deficits with right cerebral hemisphere lesions is well-documented, making it the correct choice in this context.
