Epoch data

The epoch data are a fieldtrip format structure, all epochs are aligned with fixation onset to a given word, with the length of one second.Epochs were named as the combination of acquizaton date, subject code, and data type. Epochs that ended with 'Targ60' are from the first sentence set; ended with 'JEP60' are from the second sentence set (adapted from Degno et al. 2019, Journal of Experimental Psychology); ended with 'BL' were the baseline period of the first sentence set.<br>This filed 'trialinfo' is the information about each trial, the header of all columns are as followings:1- sentence_id: sentence number for this epoch2- word_loc: the location of the current word in a sentence3- loc2targ:location distance between the current word and target word; loc2targ for pre-target, target, post-target are -1, 0, and 14- word_freq: CELEX frequency 5- word_length6- saccade2this_duration: saccade duration toward this word7- fixation_on_MEG: MEG trigger for fixation onset to this word8- fixation_duration 9- NextOrder: next word location minus the current word location; negative value indicates saccade backward to the previous words10- FirstPassFix: whether this fixation is the first for this word or not11- PreviousOrder: previous word location minus the current word location; negative value indicates saccade forward to the next words12- SentenceCondition: the current word is in a sentence with high or low frequency target word; 1 -- low, 2 -- high13- PupilSize: averaged pupil size during this fixation<br>
