Final answer:
Damage to the right hemisphere causes deficits in spatial cognition tasks.
Step-by-step explanation:
The deficits in spatial cognition tasks are caused by damage to the right hemisphere.
Research has shown that the right hemisphere is superior in pitch perception, arousal, and negative emotions. When there is damage to this hemisphere, it can result in difficulties in tasks that require spatial cognition, such as understanding the relationships between objects in space.
For example, in a condition called split-brain, where the corpus callosum is cut to treat severe epilepsy, patients may have difficulty verbally identifying objects presented in their left visual field, which is processed by the right hemisphere.
