Cognitive workload is the quantified demand placed on an individual's information-processing resources during a task. It is a formal construct developed in cognitive psychology and human factors engineering to model the allocation of limited attentional capacity, working memory, and executive function. The construct operationalizes 'mental effort' through measurable indices: subjective ratings (e.g., NASA-TLX), behavioral performance decrements, and physiological markers (pupil dilation, EEG theta power). It persists through standardized measurement instruments, training protocols, and the institutional practice of workload management in high-stakes domains such as aviation, medicine, and military operations.

Definition
Why it is in scope
The amount of mental effort, attention, and information-processing capacity required by a task. Human-made as a construct in cognitive psychology and human factors engineering to measure and manage the demands placed on working memory and attentional resources.

Cognitive workload is a specific kind of workload — the mental-effort dimension of demand placed on a worker. A competent speaker would call it 'a workload.' The removal test for DEPENDS_ON fails (cognitive workload does not need workload to operate — it IS a kind of workload), and Law 9 requires INSTANCE_OF for 'specific kind of general' relations.

Cognitive-workload as a concept is built for the sake of human-factors engineering. It provides the framework for measuring mental effort to inform task design that matches human cognitive capacity. Law 8d: the servant (cognitive-workload) points at the master (human-factors).
