The Effect
of Repetitive Presentation and Inducement of Simplified Form of Kanji
on Visual Field Differences

Thirty-two
Japanese students participated in a tachistoscopic recognition task.
They were unaware of a simplified form of kanji designed in the People's
Republic of China. In the experiment, a kanji written in the simplified
form was presented to the left or right visual field (LVF or RVF).
Subjects were required to depress the microswitch operated by index
finger with the appearance of two of the four stimuli, and microswitch
operated the middle finger when the other two were presented. Two
tests, each including four blocks of 24 trials, were conducted with
a one-week interval. Each kanji was randomly presented 6 times in
a block in either field. As a result of test 1, visual field difference
was not generally found. However, it reversed between the first and
second half. LVF advantage was found in the first, RVF in the second.
At the end of test 1, subjects were divided into four groups, and
three of them were induced with some attribute of the stimuli. The
other group was not taken any inducement. As a result of test 2,
which was conducted one week later, visual field difference was not
found in the pronunciation-induced groups. On the other hands, RVF
advantage was found in the meaning-induced group and non-induced
group.
