5083.46 A study of the size of pen-input character boxes for PDAs, Ren Xiangshi, Kong Jing,
Kato Taishi, Kochi University of Technology, Japan
We try to determine the optimal size of pen-input boxes for inputting characters into handheld
devices such as PDA. We define the optimal size as including the following characteristics: high
performance and high subjective ratings. Two experiments on character kinds and character shapes
were carried out. The results, which were assessed by the character recognition rate, strokes
protruding outside the character box, and subjective ratings, show that the optimal box size for
inputting alphanumeric characters is approximately 1.09 x 1.66 - 1.44 x 1.44 cm, and for Hiragana
& Katakana and Kanji & Kana is 1.44 x 1.44 cm.

Reorganization of the motor system was evaluated with fMRI in six patients suffering from focal
cerebral tumors. During scanning, the patients performed a finger-tap task with the hand
contralateral to the damaged hemisphere. As compared to the control subject, the patients showed
overactivation in ispilateral primary motor area (M1), bilateral supplementary motor area,
premotor cortex, and cerebellum. In contrast, contrallateral M1 was only modestly activated. This
study provides preliminary evidence for brain reorganization following focal brain lesions.
5083.48 Subliminal perception as automatic processing preceding recognition, Tin-cheung
Chan, The Chinese University of Hong Kong, China
Automatic processing in subliminal perception was investigated. Participants identified
two-character Chinese words as old (presented before the experiment) or new. Some new words
were preceded with a subliminal presentation of the same word (NN condition), and some with a
different new word (NN2 condition). Familiar and unfamiliar words were used. Errors were
measured. Results showed that more errors were committed in NN than in NN2 condition with
familiar word. Such effect was at maximum with SOA at 40 msec and disappeared at supraliminal
presentation of the prime. Results suggest that subliminal perception is the result of automatic
processing preceding recognition.
5083.49 Who will be benefited from the training of meditation? Hu Yueh-Luen, Karla Ding,
Guang-chu Hung, Taiwan, China
Purposes of this study is to learn the effect of meditation on child’s attention. The study would be
2*2 mixed design. Subjects are 44 4-grade students, which are divided evenly into meditator
group and non-meditator group. After meditation training, the meditation group shows no
difference in attention test from control group. However, the further analysis that separated all
subjects into high-attention group and low-attention group by their pre-test scores in the attention
test, shows that, after meditation practice, the meditator-group in high-attention group has
significant improvement in their attention ability than the control-group, but no significant
