“… how do we approach text? Do we read linearly (from start to finish), or do we seek out snippets (using a table of contents, an index, or the “Find” function for searching an online text)? Do we skim or engage in “deep” reading? Do we read quickly or slowly? Answers to these questions are often shaped by the character of the text. Is the material familiar or new to the reader? How complex are the words, the syntax, and the concepts? Functionality is also a consideration in defining reading (reading for information, for conceptual understanding, for enjoyment, or to kill time), as is the physical medium (a scroll, a paperback, an iPhone).”
