The shift from linear documents to hypertext has introduced a distinct challenge known as increased cognitive load. In traditional formats, the reader follows a singular, pre-determined path, allowing their mental energy to be focused entirely on interpreting the content. Hypertext environments, by contrast, present a landscape filled with clickable options that impose a secondary task on the reader. With every link encountered, the brain must momentarily pause to evaluate whether to follow the new path or continue reading. This repetitive act of decision-making functions as a significant drain on mental resources. Research suggests that the mere existence of these navigational choices competes with the processing of the actual text, regardless of whether the links are clicked. Consequently, the depth of engagement suffers. This is not necessarily because screens are an inferior medium, but because the structural requirement to manage navigation fractures attention. The reader is left with fewer cognitive resources to build a cohesive understanding of the material. What does the writer suggest is the primary cause of reduced engagement when reading hypertext?
