Description: This page provides the data and materials for TECO, an eye-tracking corpus containing eye movement data collected from Japanese L2 English learners during passage reading.The current version of TECO includes nine eye-tracking measures for 41 participants, with each participant reading approximately 10,000 words, totaling over 410,000 words. These measures are: (a) skipping, (b) first fixation duration, (c) gaze duration, (d) total fixation duration, (e) number of fixations, (f) refixation, (g) regression-in, (h) rereading, and (i) regression path duration. The corpus also provides additional information about the words in the passages read by the participants, such as their length, frequency, and position.
