to study deception and false-belief understanding. Study tested the preschooler aged 2-3 to 6-7
years old, found that deception is a developing skill in the preschool years and has three phases.
First is the behavioristic phase (2,3-year-olds) in that children understand how acts affect another’s
behavior but not their beliefs. Second is the mentalistic phase of first-order beliefs (4,5-year-olds),
children recognize how acts affect another’s beliefs. Last is the mentalistic phase of second-order
beliefs (6,7-year-olds), children understand deceptive behavior linked to second-order beliefs.
2083.5 The effect of dimensional salience on children’s discriminability of objects, Jinxiang
Zheng, Guoen Yin, Rong An, China
Thompson’s triad classification task and Navon’s hierarchical pattern stimuli were used to explore
dimensional salience effects on discriminability of objects in 4-, 5-, 6-year-old children. In
experiment 1, subjects viewed three objects in every figure and matched two together in free
experiment. The result showed salience effects not only occur between color and shape, but also
occur between global and local level; In experiment 2, It is showed that high dimensional salience
can significantly speed children’s perceptual response and improve their accurate than the low by
different subjects with different instructions as the base to discriminate the same stimuli.
2083.6 The developmental characteristic of encephalofluctuography in children and adolescents
in the memory conditions, Chongde Lin, Jianzhong Wo, Huijuan Liu, Beijing Normal
University, China
Twenty-four students (age 7-18) were randomly assigned to explore characteristics of
ET(encephalofluctuography) in the memory conditions. The results are as follows: Under memory
conditions, the frequency of S1 and S2 decrease significantly, those who scored higher in the
memory tests decrease more significantly than those who scored lower in the same tests. The male
students’ power of right brain decrease, while female students’ power of left brain area increase
with increase of age. In addition, the left-dominant subjects’ power in left front hemisphere
decrease, while the right-dominant subjects’ power in the right hemisphere increase.
2083.7 Peculiarities of classification and seriation thought operations in a child’s seventh year,
Saule Raiziene, Bronislava Grigaite, Vytautas Magnus University, Lithuania
The research analyses the development of classification and seriation operations under the
influence of training. Eighty-four children in their seventh year took part in the research.
Experimental groups participated in the four months training. While one experimental group
received the training corresponding to the development stage of children in their seventh year, the
other group's training (semantic mapping) exceeded their development stage. Thought operations
were assessed using the following criteria: child's ability to anticipate classification schemas, to
change criteria of classification, to understand class-inclusion relations, to perform
multiplicational classification and to anticipate seriation schemas as well as to seriate objects.
2083.8 Children’s explanations for biological phenomena, John Taplin, Llainey Smith,
University of Adelaide, Australia
Previous research has suggested that children and adults may engage in at least two kinds of
biological reasoning. The first attributes biological phenomena to vitalistic or mechanistic (i.e.,
antecedent) causes, while the second seeks to account for these phenomena in teleological (i.e.,
