The effect of repeated writing on memory.
Open accessAbstract
Repeated writing, or rehearsal by writing, is a common memory strategy for the Japanese, especially when learning new logographic characters. The to-be-remembered items are written down not as external prompts, as with reminder notes, but to be memorized in the course of writing them down over and over again. In this study, we investigated whether the strategy was effective, and if so, in which condition. Experiment 1 showed that repeated writing improved memory for graphic designs but not for Chinese characters, words, or syllables. Experiment 2 showed that the effect occurred for both Japanese and American subjects, suggesting that it was not the result of a cultural background associated with a logographic language. Instead, the effect seemed to be accounted for by the encoding specificity of visual-motor information, because repeated writing improved free recall--that included writing--but did not improve recognition (Experiment 3). In Experiment 4, the strategy was applied to learning the Arabic alphabet. Finally, similarities between repeated writing and Type 1 rehearsal are discussed.

Previous behavioral studies argued that the learning advantage of handwriting over typing is due to motor-perception integration occurring during handwriting, as handwriting movements facilitate recognition of abstract graphic forms, letters, and written words.
“Previous behavioral studies argued that the learning advantage of handwriting over typing is due to the motor-perception integration occurring during handwriting as handwriting movements facilitate the recognition of abstract graphic forms (Hulme, 1979; Naka and Naoi, 1995), letters (Longcamp et al., 2005, 2006), and written words (Kiefer et al., 2015).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
