目的:本研究旨在研究神经反馈系统对认知技能的影响,根据韦氏儿童智力量表修订版(WISC-R)的测量,在100名8至12岁被诊断为注意力缺陷的儿童中。
方法:采用随机单盲假手术对照组设计,实验组50名参与者接受神经反馈训练,假手术组50名参与者接受模拟训练.参与者是通过随机抽样从在专业教育中心寻求援助的个人中选出的,为期一年(2021年5月至2022年)。对两组进行测试前和测试后WISC-R评估,以评估参与者的心理表现。实验组共进行了60次基于定量脑电图的低频神经反馈训练,在五个月的时间里,每周三天进行半小时的会议。在第6个月结束时施用测试后WISC-R。
结果:结果显示,培训前和培训后的测试成绩之间存在显着差异,特别是在言语智商方面,图片排列,性能IQ,和总智商(分别为p=0.016,p=0.001,p<0.001和p=0.002),比较两组之间的差异。
结论:这些发现表明表现智商有了显著的提高,总智商,根据WISC-R评估,神经反馈组的注意力缺陷减少。未来的研究应该考虑采用更大的样本量,包括适当的对照组,并进行长期随访以进一步阐明这些结果的临床意义。
OBJECTIVE: This study aims to investigate the effects of a
neurofeedback system on cognitive skills, as measured by the Wechsler Intelligence Scale for Children-Revised (WISC-R), in a cohort of 100 children aged 8 to 12 who were diagnosed with attention deficit.
METHODS: A randomized single-blind sham control group design was employed, with 50 participants assigned to the experimental group receiving
neurofeedback training and 50 participants assigned to the sham group receiving simulated training. Participants were selected through random sampling from individuals seeking assistance at a specialized education center over the course of one year (May 2021-2022). Pre- and post-test WISC-R assessments were administered to both groups to evaluate participants\' mental performance. The experimental group underwent a total of 60 sessions of quantitative electroencephalography-based infralow frequency
neurofeedback training, with half-hour sessions conducted three days a week over a five-month period. The post-test WISC-R was administered at the end of the sixth month.
RESULTS: The results revealed significant differences between the pre- and post-training test scores, specifically in terms of verbal IQ, picture arrangement, performance IQ, and total IQ (p = 0.016, p = 0.001, p < 0.001, and p = 0.002, respectively), when comparing the differences between the two groups.
CONCLUSIONS: These findings indicate a notable improvement in performance IQ, total IQ, and a reduction in attention deficits among the
neurofeedback group based on the WISC-R assessments. Future studies should consider employing larger sample sizes, including appropriate control groups, and conducting long-term follow-ups to further elucidate the clinical significance of these results.
