Abstract

Objective To explore the characteristics of event-related potential(ERP) in the development of alert attention of children aged 6-11 years old. Methods A total of 144 children aged 6-11 years old were enrolled in a continuous performance test (CPT, Go/Nogo stimulus task). The latency and amplitude of frontal region cue/uncue-P3 and CNV were analyzed and compared in all age groups. Results (1)Behavioral comparison among different age groups: correct number(35(31, 38), 37(34, 38.25), 37(34.75, 39), 38(35, 39.25), 39(37.25, 40), 39(39, 40)), correct reaction time((566.88±86.63)ms, (530.10±83.40)ms, (509.17±88.99)ms, (488.31±76.23)ms, (463.45±75.78)ms, (417.24±75.78)ms), the differences were statistically significant(P<0.01). (2)Fz lead ERP characteristics: ①Comparison of cue-CNV and uncue-CNV: 6-year-old group((-8.54±4.56)μV vs (-10.13±6.36)μV), 7-year-old group((-9.20±5.34)μV vs (-11.53±4.29)μV), 8-year-old group((-8.37±4.78)μV vs (-11.35±6.38)μV)in amplitude and 9-year-old group((689.25±268.22)ms vs (826.13±174.62)ms)in latency were significantly different(P<0.05). ②Comparison of cue-P3 and uncue-P3: 6-year-old group((4.29±4.11)μV vs (7.45±3.83)μV), 7-year-old group((4.47±4.71)μV vs (5.82±4.40)μV), 8-year-old group((3.76±3.39)μV vs (6.24±4.91)μV), 9-year-old group((4.27±3.57)μV vs (5.93±3.08)μV), 11-year-old group((4.24±4.66)μV vs (6.13±4.42)μV)in amplitude were significantly different(P<0.05). ③Longitudinal comparison among age groups: the latency of cue-CNV in 9-year-old group and 11-year-old group were shorter, and the difference was significant(P<0.05). The amplitudes of cue-CNV and cue-P3 in 10-year-old group were shorter than those in other age groups(P<0.05). Conclusion With the increase of age, the reaction time of school-age children shortened and the correct rate improved.The age of 9-10 may be the high-speed period of the development for brain network on vigilant attention and psychological prediction which may be related to the maturation and development of frontal cortex.

学龄儿童警惕性注意发展的事件相关潜在特征分析

目的探讨6-11岁儿童警觉注意发展过程中事件相关电位(ERP)的特点。方法对144名6 ~ 11岁儿童进行连续行为测试(CPT, Go/Nogo刺激任务)。分析比较各年龄组额叶区cue/uncue-P3和CNV的潜伏期和振幅。结果(1)不同年龄组的行为比较:正确反应次数(35(31,38)、37(34,38.25)、37(34.75,39)、38(35,39.25)、39(37.25,40)、39(39,40))、正确反应时间((566.88±86.63)ms、(530.10±83.40)ms、(509.17±88.99)ms、(488.31±76.23)ms、(463.45±75.78)ms、(417.24±75.78)ms)，差异均有统计学意义(P<0.01)。①线索- cnv与未线索- cnv的比较:6岁组(-8.54±4.56)μV vs(-10.13±6.36)μV)、7岁组(-9.20±5.34)μV vs(-11.53±4.29)μV、8岁组((-8.37±4.78)μV vs(-11.35±6.38)μV)振幅和9岁组((689.25±268.22)ms vs(826.13±174.62)ms潜伏期差异有统计学意义(P<0.05)。②cue-P3与uncue-P3的比较:6岁组((4.29±4.11)μV vs(7.45±3.83)μV)、7岁组((4.47±4.71)μV vs(5.82±4.40)μV)、8岁组((3.76±3.39)μV vs(6.24±4.91)μV)、9岁组((4.27±3.57)μV vs(5.93±3.08)μV)、11岁组((4.24±4.66)μV vs(6.13±4.42)μV)振幅差异有统计学意义(P<0.05)。③年龄组间纵向比较:9岁组和11岁组的线索- cnv潜伏期较短，差异有统计学意义(P<0.05)。10岁组的cue-CNV和cue-P3的振幅较其他年龄组短(P<0.05)。结论学龄期儿童随年龄增长反应时间缩短，正确率提高。9-10岁可能是大脑警惕注意和心理预测网络的高速发展时期，这可能与额叶皮层的成熟和发育有关。关键词:事件相关电位;学龄儿童;警惕的注意

期刊介绍： "Chinese Journal of Behavioral Medicine and Brain Science" (CN 37-1468/R, ISSN 1674-6554) is a national academic journal under the supervision of the National Health Commission, sponsored by the Chinese Medical Association and Jining Medical College. The journal was founded in June 1992 and was formerly known as "Chinese Journal of Behavioral Medicine" (1992-1993) and "Chinese Behavioral Medical Science" (1994-2008). In 2009, it was renamed "Chinese Journal of Behavioral Medicine and Brain Science" with the approval of the State Administration of Press, Publication, Radio, Film and Television. The purpose of "Chinese Journal of Behavioral Medicine and Brain Science" is to implement the health and health policies of the Party and the State, implement the principle of combining theory with practice and popularization and improvement, and reflect the major progress in the theory and practical application of behavioral medicine and brain science in my country. It publishes academic papers and scientific research results in the field of behavioral medicine and brain science in my country, and has columns such as monographs/reviews, basic research, clinical research, health prevention, methods and techniques, psychological behavior and evaluation, and systematic evaluation.
