were better tracked than identical objects. This study investigated the effect of different ways of
feature-changing on MOT. The results showed that object-feature changing would affect
multiple-object tracking, especially the exchanging of features between two colliding objects.
1063.24 Study of the neuropsychological characteristics of selective attention in the children
with nonverbal learning disabilities, Jing Jin 1 , Wang Qingxiong 1 , Chen Xuebin 1 , Yang
Binrang 1 , Morinaga RyoKO 2 , 1 ZhongShan University, China; 2 Shirayuri College, Japan
With Auditory Detection Test (ADT), WCST and C-WISC, 14 children with NLD and 23 control
were tested and the results of sub-tests of C-WISC were analyzed with factor analysis. Compared
with control group, the correct response rate of ADT in NLD group was much lower, and incorrect
response was much more; categories achieved (CA) and perseverative errors (PE) of WCST were
much lower. Factor analysis showed that the NLD group were obviously lower than those in
control group. Children with NLD had attention control disorder and working memory disorder
mainly in frontal lobe and we supposed that the disorder in right frontal lobe was distinctive.
1063.25 Biased competition account of object-based attention on global precedence, Wenfeng
Chen, Shulan Jiao, Institute of Psychology, Chinese Academy of Sciences, Beijing, China
The study investigated object-based attention in hierarchical pattern, and suggested an alternative
view of global precedence. Object repetition procedure was applied in experiment1, 2 to
investigate object attention in hierarchical pattern. Within Biased Competition Account,
Experiment3, 4, 5 investigated how top-down and bottom-up aspects influence the processes of
global/local level. Results showed an object repetition effect and an asymmetric effect of
global/local level, and global advantage varied with top-down and bottom-up cues. In conclusion,
there was an asymmetric object attention effect in hierarchical pattern, and it was influenced by
the cooperation and competition of top-down and bottom-up biases.
1063.26 Why do smiling faces look feminine, Satoru Kawamura, Osaka University, Japan
A hundred four subjects evaluated the female-likeness for 200 photos of smiling and serious look
faces. The result showed that smiling faces look more feminine than serious look faces
irrespective of the sex of faces. Whether there are common physical elements between smiling
faces and female faces was examined by applying PCA to pixel-based luminosity data. No
common elements between smiling and female faces are found. It is suggested that the effect of
smiling on sexuality evaluation is caused by experiential or social factor based on the fact that
females smile more often than males.
1063.27 Pre-attentive representation of number, Imiko Bara, Syoichi Iwasaki, Tohku University,
Japan
Both human beings and animals can judge the number of up to four stimuli without counting. To
test whether this ‘subitizing’ is an automatic, pre-attentive process, we conducted a priming
experiment in which participants classified digits according to whether it was larger than 5 or not.
Randomly arranged dots preceded digit presentation. When the number of dots matched the digit 5,
the reaction time was shorter than when it did not even though the number of 5 dots was judged to
be 4 on most of the trials.
