| 其他摘要 | As is well known, the objective perception of time is a fundamental ability for individual survival and development, which undergoes changes with age. Time perception is a continuous and sequential subjective experience of objective events in time, and it is an important concept in cognitive psychology and a key tool for individuals to explore the world. In the field of time perception research, the development of children's temporal interval perception has special significance, and primary school is an important stage in the development of children's temporal interval perception. Studying the characteristics of children's temporal interval perception development is mainly reflected in the accuracy of time perception and the sensitivity of time judgment.
This study selected primary school children aged 6-12 as the research subjects, and adopted the temporal bisection research paradigm to explore the developmental characteristics of temporal interval perception in children of different ages. The research process is divided into two stages. The first stage is the training stage, where participants are required to learn about the "long" time interval (1600 ms) or the "short" time interval (400 ms) to enhance their memory of these intervals. The second stage is the testing stage, where participants need to determine whether the time interval (400 ms, 600 ms, 800 ms, 1000 ms, 1200 ms, 1400 ms, 1600 ms) between previously learned and not learned intervals is closer to the "long" or "short" time interval.
First, the ratio of children's judgments as "long" time intervals under each test interval is calculated. Then, the subjective time bisection point is calculated to assess the accuracy of reaction time. Additionally, the difference threshold for the sensitivity of reaction time indicators and the Weber ratio are calculated. Statistical analysis is conducted to analyze the results. The results indicate that: (1) the difference between age and subjective time bisection point is not significant, and the difference between gender and subjective time bisection point is not significant. (2) Age has a significant difference in the threshold of difference, while gender has a significant difference in the threshold of time. As age increases, the threshold of difference decreases; The difference threshold of male children is lower than that of female children. (3) The difference between age and Weber's ratio is significant, while the difference between gender and Weber's ratio is not significant. As we age, the Weber ratio decreases.
The main findings of this study are as follows: firstly, the subjective time bisection point does not reflect the characteristics of age stages but only shows a slow upward trend. The older the age, the closer the subjective time bisection is to the standard time interval (1000 ms), and the time extension effect gradually weakens. Secondly, the difference threshold and Weber ratios show the characteristics of age differences. With the growth of age, the sensitivity of children's perception of time becomes stronger and stronger, which can be detected only by a temporal interval difference. Thirdly, the difference threshold exhibits gender differences, with male children having a higher sensitivity to time perception than female children. The results of this study contribute to a further understanding of the developmental characteristics of the accuracy and sensitivity of children's temporal interval perception. |
