中文双字词字体与词频在 N400上的交互作用

为验证中文的N400字体效应,探索字体和使用频率在语义提取上的交互作用,以大学生为被试,采用事件相关电位(ERP)技术和真假词判断任务,操控双字词的字体和频率,记录被试对真假双字词的判断反应和ERP,结果表明:行楷体比宋体引发更负的N400波幅,且在低频真词上更显著,另外在真词条件下,频率和字体在N400上存在交互作用.认为字形在语义通达中起到重要作用,支持中文形-义加工说和交互激活模型,不支持多阶段激活模型.

Interaction of Word Font and Frequency on N400 in Chinese Compound Words

In this article,the mathematical model of the first level rotary inverted pendulum system has been deduced according to the Lagrange''s equations.The swing part of the motor uses the Lyapunov equa-tion to analyze,and uses the swing rod potential deviation as a control measurement to make the system closed loop control,making the system swing rod be controlled,after the success of the inverted pendulum swing up,in the inverted pendulum unstable equilibrium point to linearize the system model,and the double closed loop PID control algorithm of inverted pendulum model rotation arm position and the swing arm position stability control and the use of 32 bit MCU experimental platform is built to verify the actual. The results show that this control method which is introduced in this article can make the rotary arm rest-ing reasonable and swing arm stability lies in the effect of unstable equilibrium point.
