It is a well-known observation that when a <i>Kanji</i> character is viewed steadily and continuously, the viewer often becomes unable to recognize the <i>Kanji</i> as a whole pattern and it becomes difficult to judge whether or not the <i>Kanji</i> is orthographically correct. Such a phenomenon is called the "Gestaltzerfall" of <i>Kanji</i> characters. In the present study, two experiments were carried out to examine delays in the recognition of test <i>Kanji</i> following 25 s of prolonged viewing of adaptation <i>Kanji</i>, which were comprised of either the same or different parts and structures. When the size of the adaptation <i>Kanji</i> was equal to that of the test <i>Kanji</i>, there were significant delays of more than 50 ms, both when the stimuli were of the same pattern, and when they had the same structure but different components. However, when their sizes were different, delays were found only when the test and the adaptation <i>Kanji</i> were of the same pattern. These results suggest that a <i>Kanji</i> pattern may be internally represented as a whole, independent of its size, while the processing of <i>Kanji</i> structure may be dependent upon its size. Prolonged viewing may produce an adaptation effect specific to such representations.
