摘要
考察2岁、4岁和6岁3个组共104名有效被试,在基线状态下的基线迷走紧张以及与年龄相符的中等压力任务下的迷走抑制的发展。结果发现,基线迷走紧张与迷走抑制有不同的发展模式:4岁组、6岁组儿童的基线迷走紧张显著地高于2岁组,而4岁组与6岁组之间没有显著差异,基线心跳周期随年龄的增长而相应增长;迷走抑制没有年龄差异,6岁组的基线对任务的心跳周期变化显著地大于2岁组的心跳周期变化。
In this study, Cardiac vagal tone and heart period were measured in a sample of 104 children （aged 2, 4, and 6） to evaluate the development of vagal regulation at rest and during age-appropriate mild stress task. The development patterns ofchild baseline vagal tone and child vagal suppression were different： （1） Child baseline vagal tone increased with age in early childhood. The baseline vagal tone of 4 years and 6 years were significantly higher than that of 2 years, but there was no significant difference between that of 4 years and 6 years. Child baseline heart period increased with age. （2） Child vagal suppression didnt increase with age. Child baseline-to-task change in heart period of 6 years was significantly higher than that of 2 years, and there were no differences between those of other groups.
