2098.24 Experimental study of eye-movement characteristics in children and adolescents’
classification, Binrong Dai, Guoli Yan, Zhengping Liu, Guoen Yin, China
The experiment was designed to study the eye movement characteristics of different age groups
while they were classifying the materials. 72 subjects including primary pupils, junior high school
students and undergraduates were from Tianjin, their intelligence and eyesight were normal. The
materials were consisted of 54 perceptually different pictures which were divided into 3sets.These
materials were presented in 2 conditions. The results showed: The materials-presenting modes had
effect on subjects’ classification, the numbers of area of interest, duration of fixation, times of
fixation, the size of the pupil diameter, and all factors were different with ages.
2098.25 Explicit memory and social communication in infancy as precursors for cognitive
development at 4 years, Karin Strid 1 , Mikael Heimann 2 , Tomas Tjus 1 , Lars Smith 3 , 1 Goteborg
University, Sweden; 2 University of Bergen, Norway; 3 University of Oslo, Norway
Memory and social communication in infancy was tested as precursors for cognitive development
at 4 years in typically developed Swedish children (n=30). At 9 and 14 months the children’s
memory was examined using three different deferred imitation tasks on actions with objects. At 14
months they conducted the joint attention part of the Early Social Communicative Scale. At 4
years they were given the McCarthy Scales of Children’s Abilities. Memory and social
communication together explained 25% of the variance on McCarthy. The mean score on
McCarthy was higher for individuals performing above mean on both deferred imitation and joint.
2098.26 Five to ten years old children’s individual differences in strategy choices, Hong Zhang,
Wo Jianzhong, Beijing Normal University, China
The participants in this research were 144 5-10 years old children. We used different addition
problems to examine the individual difference in strategy choice. In solving the addition problems,
various strategy rate of utilization had remarkable difference. Retrieval, counting up from the
larger number and rounding strategy were faster than other strategies on 5-7 years old children.
For 5-6 years old children, there was no difference in RT, but the perfectionists used more
strategies. For 7-10 years old children, there was no significant difference in strategy choice, but
the perfectionists used retrieval and rounding strategy faster than the not-so-good students.
2098.27 Development of different components of theory of mind and their relations to preschool
children’s prosocial behavior and peer acceptance, Jingxin Zhao, Wenxin Zhang, Shandong
Normal University, China
Development of children’s attribution of second-order false-belief and second-order
emotion-understanding and the relative contribution of theory of mind and prosocial behavioral to
children’s peer acceptance were examined in two related studies. The subjects were 108 children
aged 3-6. Measures of theory of mind were two false-belief tasks and two emotion-understanding
tasks. It was found that the two components of theory of mind showed different trend of
development. Prosocial behavior was the best predictor of children’s peer acceptance. However,
the prediction power of children’s theory of mind and prosocial behavior to peer acceptance varied
with age.
