Abstract

We investigated effects of delayed visual feedback on handwriting some familiar English words, using various delays -0. 33. 67, 100, 133, 167, 267, and 500 ms. With increasing the delay, the writing error rate increased. Among the writing errors, there was a tendency for some additional strokes to be inserted, especially for some original strokes to be duplicated. This type of error named “addition error” was observed frequently where a set of strokes should be repeated (e.g. the word “feeling” was often misspelled as “feeeling”). These results indicate that visual monitoring is indispensable in producing repetition of a set of strokes.
