Imitation of Grasping Animals Activates Motor Inhibition

The experimental apparatus was a Lenovo computer connected to a 17-inch cathode ray tube (CRT) monitor (85-Hz refresh rates). Stimuli were presented using E-prime 2.0 software (version 2.0, Psychology Software Tools, Inc. Pittsburgh, PA, USA). The input device was a standard keyboard. Electroencephalogram (EEG) data were recorded by a Neuroscan system (Neuroscan, Inc.). A Neuroscan Synamp 2 amplifier with a 64 Ag/AgCl electrode cap mounted according to the extended international 10–20 system was used to continuously record EEG data (sampling rate at 500 Hz).

本实验所用实验装置为联想（Lenovo）计算机，外接一台17英寸阴极射线管（cathode ray tube, CRT）显示器，刷新率为85赫兹。实验刺激通过E-prime 2.0软件（版本2.0，美国宾夕法尼亚州匹兹堡市Psychology Software Tools, Inc.公司开发）呈现。输入设备为标准键盘。脑电图（Electroencephalogram, EEG）数据采用Neuroscan系统（Neuroscan, Inc.公司）进行采集。本实验采用搭载64个银/氯化银（Ag/AgCl）电极帽的Neuroscan Synamp 2放大器，按照扩展国际10-20系统排布电极，以500赫兹的采样率连续采集脑电数据。
