consistent with the findings of research on motor response inhibition in ADHD children,
suggesting that there could be some common cognitive and brain mechanisms in these two kinds
of executive inhibition, and the combined subtype of ADHD were impaired more severely than
predominantly inattentive in these mechanism.
2098.12 The regression analysis between perceptual speed ability and inductive reasoning ability
in adulthood, Mingyue Wang, Jiliang Shen, Beijing Normal University, China
A sample of 221 adults aged 20s-70s participated in this 3-year longitudinal project in which The
Kit of Factor-referenced Cognitive Tests was given. After the background variables and the
stability of each ability were controlled, the regression analysis showed that inductive reasoning
ability could be significantly and positively predicted by perceptual speed ability, but in turn,
perceptual speed ability could not be predicted significantly by inductive reasoning ability. While
some researchers used to consider the Primary Mental Abilities parallel related, whether
perceptual speed ability was more primary than inductive reasoning ability is discussed.
2098.13 Is work memory an entity of EFs, Yiyuan Li, Hong Li, Southwest China Normal
University, China
This study carried out two experiments to illustrate whether work memory (WM) is an entity of
executive functions (EFs). Experiment 1: 3-, 4-, and 5-year-olds were given a battery of “cool” EF
and “hot” EF measures. We found that children could not perform the above two tasks, even they
had accomplished the WM questions. Experiment 2: the measures used in above were modified to
reduce the WM demands. The result showed that there was no significant difference between the
two experiments. Therefore, we argued that WM plays an important role in higher-order cognition,
but it cannot act as an entity of EFs.
2098.14 Development of probability reasoning in third and forth-grade children, Yujing Ni, The
Chinese University of Hong Kong, China
This study, involving 120 third and fourth-grade students, examined how numerical relation
between the parts in a probability task (e.g., 2:2 vs. 5:5 or 1:2 vs. 2:4) poses a constraint on
children’s reasoning multiplicatively. More than half of the students could solve the tasks of
special equivalent class (e.g., 2:2 vs. 5:5), a clear indication of multiplicative reasoning. However,
very few of them could solve the tasks involving other equivalent classes (e.g., 1:2 vs. 2:4). The
special status of the special equivalent class in probability reasoning of children, with regard to its
developmental mechanism and instructional potentials, was explored.
2098.15 Development of self-belief and that of others for preschool children, Guoen Yin 1 ,
Youqing Chen 2 , Bing Zhang 3 , 1 Tianjin Normal University, China; 2 Nanjing Xiaozhuang College,
China; 3 The Command College of the Armed Police Forces, China
This research discussed developing features of self-belief and that of others for preschool children,
which showed: 1. 3-year-old children not only master their own correct belief, but also do that of
others, the latter ability for 4-year-old children decrease, that for 5-year-old children gets stable; 2.
In the task of perception and belief, 3-year-old children not only master false belief of themselves,
but also do that of others; 3. However, in the experiment of representational change task, not until
4-year-old children can master false belief of themselves, 5-year-old children can do that of others.
