Cross-cuing refers to the phenomenon where split-brain patients use indirect signals or cues from one hemisphere to the other to communicate information. In the context of the test mentioned, even though the corpus callosum (which connects the two hemispheres of the brain) is severed in split-brain patients, they might still use other, more indirect ways to share information between hemispheres, such as facial expressions or sounds, to indicate their perception of color in the left visual field. This is known as cross-cuing.
