Re‐examining cognitive load measures in real‐world learning: Evidence from both subjective and neurophysiological data

Cognitive load theory is widely used in educational research and instructional design, which relies heavily on conceptual constructs and measurement instruments of cognitive load. Due to its implicit nature, cognitive load is usually measured by other related instruments, such as commonly-used self-report scales of mental effort or task difficulty. However, these concepts are different in nature, as they emphasize distinct perspectives on cognitive processing. In addition, real-world learning is more complex than simplified experimental conditions. Simply assuming that these variables will change in a monotonic way with workload may be misleading.
