Analysis for Musical Effects on Education and Treatment and Applied for Special Education

本研究是为“特殊教育中的音乐途径”而进行的。在特殊教育领域，“情绪障碍儿童的音乐途径”备受关注。在特殊学校中，音乐课程内外都有许多指导原则。因此，对音乐的心理生理学研究是非常重要的。本研究有两个途径。一是音乐倾听和乞讨的心理生理实验。二是利用数字处理技术消除伪迹的基础研究。在琉球大学第一年准备了录音系统。根据野外使用情况，我们还研制了便携式脑电地形图记录系统，可用于基础实验和/或野外研究。从正常受试者的应用心理生理学实验来看，听音乐使觉醒水平的构成有下降趋势。因此，几种音乐可能具有“唤醒L效应”。此外，“记忆集”的差异也是非常重要的。在以后的研究中，当我们计划实验设计时，我们必须考虑“心理集”。情绪障碍儿童的脑电通常含有多种类型的伪像。利用数字处理技术(FIR数字滤波)，我们可以精确地消除高频脑电伪影。与高阶FIR数字滤波器(265维)和移动平均或模拟滤波器相比，我们检验了脑电波形的差异。

This study was planned for "Musical approach for the special education".In the field of special education, active attention on "Musical approach for emotionally disturbed children".In the special schools, there were many guidings principle in or out of the curriculum of music.For this reason, it is important of psychopysiological study for the music.This report has two-way to approach.First is the psychophysiological experiment on musical listening and BEG changing. Second is the fundamental study for artifacts elimination by using the technique of digital processing technique.In the 1^<st> year, prepared recording system at Univ.Ryukyus. And 2^<nd>.Year, we also prepared portable BEG recording system according to use in the fields working.These recording systems were reasonable for fundamental experiment and/or fields study.Listening to music bring to constitution of the arousal level, trended to maintain downward consciousness, from applied psychophysiological experiment with normal subjects. Thus, several music may have the "control of the arousal l&vel".And also it was very important things about difference of "niental set".In the future study, we have to consider the "mental set", when to plan the experimental deign.The BEG from emotionally disturbed children, they are usually contained many types of artifacts.By using the technique of digital processing technique(FIR digital filter), we can precisely eliminate the high ftequency BMG artifacts.Compared with high cut FIR digital filter(265 dimensions)and moving average or analog filters, we checked out difference of BEG wave form.
