Apparatus
’ head movements
EyeLink 1000 plus (Tower mount model; SR research) was utilized to record eye movements with a sampling rate of 2k Hz during reading. A chin and forehead rest were used to minimize participants’ head movements. The resolution of the monitor is 1280 × 1024 pixels. A viewing distance was set as around 56 cm and each English letter extended about 0.3 degrees of horizontal visual angle to simulate natural reading situations
