The CRI and Bonds defense mechanism test were used to compare the groups self perceived
coping and defense mechanism resources. The study revealed significant differences between the
CLP and the control when the groups were divided by gender. The implication of the result is
addressed with thoughts about future studies in this realm.
5083.199 The development of cognitive and social verbal expression among children aged from
3.5 to 6.5 years old and their correlations, Zheng Zhang, Chuanhua Gu, Huichang Chen,
Beijing Normal School for Preschool Education, China
The development of cognitive and social verbal expression and their correlations of randomly
selected 107 young children aged from 3.5 to 6.5 years old from Fuzhou city of Fujian Province
were investigated by the Cognitive Verbal Expression Test and the Social Verbal Expression Test.
The results indicated that: 1. Most young children tended to describe an object from the exterior
characteristic rather than from the interior characteristic; 2. Both the cognitive verbal expressive
ability and social verbal expressive ability increased with age generally, however remarkable
growth of them happened at different age. 3. They correlated positively with each other.
5083.200 The trait anxiety of the national handball referees, Alexandro Andrade, Caroline Di
Bernardi Luft, Fabiano Souza Pereira, University of the Santa Catarina State, Brazil
This study investigated the trait anxiety of the national handball Brasilian referees (n=36), age= 33
years old (-21, +51), arbitration experience= 12 years (-3+25). The trait anxiety was evaluated by
the Trait Anxiety Inventory of Spielberger et al. (1979). The referees have an active lifestyle (30
actives; 6 sedentary). The actives showed a level of anxiety about 43,6 (s=3,95) and the sedentary
42 (s=5,02). The majority of actives (23/ 76,6%) scored middle to high anxiety. The sedentary
ones scored in the same way. We concluded that the national handball referees has a low level of
anxiety.

5084.1 Combining reduced dimension with BP Neural Network of estimating parameters in
3PLM, Shuliang Ding, Yunlan Tan, Ruiming Xin, Fen Luo, Xijuan Wang, JiangXi Normal
Unversity, China
The reduced dimension method (RDM) is an important statistical technique. For estimating the
parameters in 3-parameter Logistic model (3PLM) RDM is combined with BP Neural Network.
Monte Carlo study shows that the item parameters estimation is more precise than the current
prevailing software. The well-trained Neural Network can output the estimate value in field test
and needs less number of examinees and items. The errors between estimate values and true
values are very small. The experiment shows that the behavior of the simulation data drawn from
normal distribution is better than those drawn from uniform distribution.
