Language performance is thought to be related to the functional specialisation of the brain, and particularly to the degree of asymmetry of activity in the two cerebral hemispheres. A microprocessor-based system has been constructed to investigate the relationship between the analogous asymmetry of the EEG and language ability in young children. The system is based on the Intel 8086 microprocessor, with software written both in the high level language PL/M-86 and 8086 assembly language. A test script, instructing the child to perform various lateralised tasks, is played from a cassette recorder to provide a constant stimulus across subjects. The computed power spectra of the resulting EEG waveforms, and the hemispheric specialisation, represented by a derived dominance factor, have been analysed both visually and numerically. Results from a test group of 16 children have not shown a strong correlation between the dominance factors and the related reading quotient.
语言能力被认为与大脑的功能特化有关,尤其是与两个大脑半球活动的不对称程度有关。已经构建了一个基于微处理器的系统来研究幼儿脑电图类似的不对称性与语言能力之间的关系。该系统基于英特尔8086微处理器,软件用高级语言PL/M - 86和8086汇编语言编写。一个测试脚本从盒式录音机播放,指导孩子执行各种偏侧任务,以便为不同受试者提供恒定的刺激。对所得脑电图波形的计算功率谱以及由导出的优势因子表示的半球特化进行了视觉和数值分析。来自16名儿童的测试组结果并未显示优势因子与相关阅读商数之间有很强的相关性。
