Cognitive load

Origin

The concept of "cognitive load" emerged from the burgeoning field of cognitive psychology in the mid-to-late 20th century. It was prominently developed by Australian educational psychologist John Sweller in the late 1980s and early 1990s as a core component of his Cognitive Load Theory. Sweller and his colleagues sought to understand how instructional design could optimize learning by considering the inherent limitations of human working memory. They realized that when learning tasks placed too many demands on our finite mental resources, it hindered true understanding. This insight shifted the focus from merely presenting information to strategically designing learning experiences that manage the brain's "bandwidth," ensuring that precious mental effort is directed towards learning, not just processing overwhelming data.
