The Possibility Of 4-year-old Children's Processing Efficiency Research On The Computer

Thirty one four-year-old children were tested in the research, which is based on the Simon effect paradigm as the filtrating and practice tasks and the processing speed and control of processing tasks as the experiment part. The aim of this research is to test the reaction time and accuracy of different levels in two sessions in different field. According to the number of valid subjects, the fittest numbers of practice tasks, the design of levels of processing efficiency and the sessions of the tests, the research suggestions that the possibility of infant's processing efficiency experiments on the computer. The results show that, (a) There could be half of the subjects valid by the test of Simon effect tasks in the processing speed part. The Simon effect t task is efficient to select the valid subjects. (b) The reaction time of the valid subjects could be improved by the two practice tasks. The practice tasks and instructions are both useful to provide the opportunity for children to be familiar with the operation on the computer, understanding the instructions and mastering the rules instead of just improving the reaction time and accuracy. (c) The reaction time in different fields will be increased followed with the levels of the tasks. The accuracy of the processing speed didn't change in the spatial and quantitative filed while it will change in the verbal field, which means the tasks in those two fields are easier than the verbal field. (d) The results in session two are better in session one except the Chinese character tasks. Because the ability of the inhibition of infants is bad, there is no difference between the two sessions in the control tasks. That means one session is enough to test the infants'processing efficiency.
