Neurofeedback is a noninvasive treatment that changes brain activity in children with attention-deficit/hyperactivity disorder and thereby improves performance in these children. We examined the effect of neurofeedback on perceptual organization, visual and auditory memory in children with attention-deficit/hyperactivity disorder.
MATERIALS & METHODS: This study was quasi-experimental with pre-test, post-test design, and control group. The sample included 20 children with attention-deficit/hyperactivity disorder were selected through convenience sampling in Khorramabad, central Iran in 2017. The sample was divided into control and experimental groups. Pre-test included Rey-Osterrieth complex figure and Wechsler digit span. Rey-Osterrieth complex figure test was used to measure perceptual organization and visual memory. Wechsler digit span was used to measure auditory memory. After conducting pre-test, the experimental group participated in neurofeedback training sessions. Theta/Beta protocol was applied for all participants. The control group did not receive any intervention. Then post-test was conducted on two groups.
Neurofeedback training significantly improved visual memory (<0.001) but neurofeedback training had no significant effect on the perceptual organization (>0.05). Moreover, neurofeedback training enhanced auditory short-term memory and auditory working memory (<0.05).
Neurofeedback improved neurocognitive abilities in children with attention-deficit/hyperactivity disorder.
神经反馈是一种非侵入性治疗方法,可改变注意力缺陷多动障碍儿童的大脑活动,从而改善这些儿童的表现。我们研究了神经反馈对注意力缺陷多动障碍儿童的知觉组织、视觉和听觉记忆的影响。
本研究采用前测、后测设计的准实验,并设有对照组。样本包括20名注意力缺陷多动障碍儿童,于2017年在伊朗中部的霍拉马巴德通过便利抽样选取。样本分为对照组和实验组。前测包括雷-奥斯特里思复杂图形测试和韦氏数字广度测试。雷-奥斯特里思复杂图形测试用于测量知觉组织和视觉记忆。韦氏数字广度测试用于测量听觉记忆。在前测之后,实验组参加神经反馈训练课程。所有参与者均采用θ/β协议。对照组未接受任何干预。然后对两组进行后测。
神经反馈训练显著改善了视觉记忆(<0.001),但对知觉组织没有显著影响(>0.05)。此外,神经反馈训练增强了听觉短期记忆和听觉工作记忆(<0.05)。
神经反馈改善了注意力缺陷多动障碍儿童的神经认知能力。
