Cognitive Demand
Definition
The mental processing load a text or statement places on the reader or listener. High cognitive demand reduces accurate comprehension, particularly under stress. The Miranda warning creates high cognitive demand through unfamiliar vocabulary, abstract concepts, and the stressful context of arrest.

Common questions
What specifically about Miranda wording raises cognitive demand?+
Legal terms such as 'waive' and 'entitled', the abstract concept of a right that can be invoked later, and the stress of being under arrest all load working memory at once, which research on suspect comprehension has linked to lower accurate understanding of what the warning actually means.
How does cognitive demand differ from a suspect's general intelligence or literacy level?+
Cognitive demand is a property of the message and the situation, not the person; even a suspect with adequate literacy can fail to process a high-demand warning accurately under the acute stress of arrest, which is why comprehension studies test understanding in realistic conditions rather than relying on a reading-level score alone.
