Thanks in part to efficient search engines such as Google, on-line reading has become for many the primary way that people read. This talk will discuss how a wide range of research in web usability, psychology, education, and communication theory provides corroborating evidence that on-line reading is transforming cognition, learning, and the very nature of knowledge in some disturbing ways.

63. Word Skipping: Implications
Eye movements in reading are characterized by
short periods of steadiness (fixations) followed by
fast movements (saccades). Saccades are needed
to bring new information into the centre of the
visual field where acuity is best; fixations are
required to recognized words. … Some words are
q g
fixated more than once, some are initially not
fixated but immediately afterwards regressed to,
and some are not fixated at all.
