摘要

背景:与强直性、自上而下控制警觉性的发展观点形成鲜明对比的是,少数神经行为和神经生理学研究涉及儿童时期外源性驱动的相性警觉性的发展轨迹。目的:本研究旨在探讨年龄和性别对儿童期晚期相警觉性的影响,并在行为水平上分析强直警觉性和相警觉性之间的关联程度。方法:对10岁、11岁和12岁的典型发育儿童(N = 59,男孩27例,女孩32例)进行了基于计算机的简单手眼反应警觉性测试,其中28个试验有警告信号,28个试验没有警告信号。结果:结果显示,随着年龄的增长,警觉和非警觉状态下的平均反应时间均有适度减少。然而,警觉效应计算为警觉和非警觉条件下的反应时间差异,不受年龄和性别的影响。结论:与以往关于儿童后期阶段警觉性可能持续改善的观点不同,本研究表明,注意警觉性(阶段警觉性)的短暂性增强的神经认知功能在这一发育时期没有改变,并且是稳定的。此外,这一功能在儿童时期男女之间并无差异。

Phasic alertness indicated by simple motor reaction time in late childhood: The effect of age and sex
Background: In contrast to strongly established views on the development of tonic, top-down controlled alertness, a small number of neurobehavioral and neurophysiological studies deal with the developmental trajectory of exogenously driven phasic alertness during childhood. Objective: The current study aimed to examine the age and sex effects on phasic alerting during late childhood, and to analyse the degree of association between tonic and phasic alertness at the behavioural level. Methods: Three age groups of typically developing children, aged 10, 11 and 12 years (N = 59, 27 boys, 32 girls) performed a computer-based simple hand-eye reaction test of alertness that involved 28 trials with and 28 trials without a warning signal. Results: The results showed a moderate decrease of mean reaction time in both the alert and non-alert conditions with age. However, the alert effect calculated as the difference in reaction times achieved in alert and non-alert conditions was not affected by age and sex. Conclusions: In contrast to previous suggestions on possible continuing improvement in phasic alertness during late childhood, the current study suggested that the neurocognitive function of transient enhancement in attentional alertness (phasic alertness) does not change and it is stabilized in this developmental period. In addition, this function does not differ between males and females in childhood.
