1. A method of displaying content to a reader on a display of an electronic device comprising: presenting a first part of a text on the display; removing the first part of the text from the display in response to an input from a reader, wherein the input indicates that the reader is able to remember the first part of the text; presenting a second part of the text on the display; presenting a question to the reader, wherein the question assesses the reader's comprehension of whether the first part of the text coordinates with the second part of the text, and wherein the question assesses whether the reader can process and evaluate the second part of the text while retaining the first part of text in working memory; receiving an answer to the question from the reader, wherein the answer to the question is ‘yes’ or ‘no’; providing positive reinforcement to the reader if the answer is correct, wherein the positive feedback is provided immediately on the display; and providing negative reinforcement to the reader if the answer is incorrect, wherein the negative reinforcement comprises a wait period, and wherein the first part of the text is presented on the display after the wait period.
