ABSTRACT

After the discovery that the whole image of words is involved in the cognitive process of words, various experiments have been conducted to prove the Word Shape Effect on sentences written in Latin letters, but there have been no successful cases. On the other hand, in the experiments conducted under the expectation that the change of the stroke density between Hangul characters also determines the whole image of the word, the Stroke Density Effect (SDE) was confirmed several times. Then this study noted that the sentences written in Latin letters also show the change of stroke densities and an experiment was conducted to verify the SDE. The experiment was carried out by measuring the reading speeds of two types of documents : the SDE enhanced document that the visual brightness change caused by the different stroke density is enhanced and the SDE weakened document that the visual brightness change is weakened. As a result, the reading speed of the SDE enhanced document was higher, but it was insignificant. On the other hand, in the subjects with high reading ability, the reading speed of the SDE enhanced document was significantly faster than the SDE weakened document whereas in the subjects with poor reading ability, the reading speed of the SDE weakened document was insignificantly faster than the SDE enhanced document. These results show that the Stroke Density Effect is based on sufficient reading experiences.
