Episode Details

As you read this page your eyes do not move from left to right, letter-to-letter, word-to-word in a straight, steady line. Your brain simply gives the impression that they do. Eye movement research shows that your eyes move unevenly across the page, going back occasionally, skipping some words, and fixating on others. The small, rapid, jerky movements that your eyes make are called saccades. Where your eyes stop is called a fixation. A regression is when your eye goes back to check on a word.
