15 human participants anonymised (sub-01 to sub-15) performed a change discrimination task of a Phillips pattern in four conditions: Saccade spatiotopic, saccade retinotopic, fixation retino- and spatiotopic, and fixation retinotopic, respectively coded as SacSpa, SacRet, FixRetSpa and FixRet. ---------- **Folders structure:** /sub-0X/sub-0X_task-FixRet_BehavData.csv: trial design matrix and behavioral input of sub 0X for the fixation retinotopic task in block 0X /sub-0X/sub-0X_task-FixRet_EyeData.edf: EyeLink eye trace file of sub 0X for the fixation retinotopic task in block 0X /sub-0X/sub-0X_task-FixSpaRet_BehavData.csv: trial design matrix and behavioral input of sub 0X for the fixation spatio- and retinotopic task in block 0X /sub-0X/sub-0X_task-FixSpaRet_EyeData.edf: EyeLink eye trace file of sub 0X for the fixation spatio- and retinotopic task in block 0X /sub-0X/sub-0X_task-SacRet_BehavData.csv: trial design matrix and behavioral input of sub 0X for the saccade retinotopic task in block 0X /sub-0X/sub-0X_task-SacRet_EyeData.edf: EyeLink eye trace file of sub 0X for the saccade retinotopic task in block 0X /sub-0X/sub-0X_task-SacSpa_BehavData.csv: trial design matrix and behavioral input of sub 0X for the saccade spatiotopic task in block 0X /sub-0X/sub-0X_task-SacSpa_EyeData.edf: EyeLink eye trace file of sub 0X for the saccade spatiotopic task in block 0X ---------- **Behavioral data columns:** Column #01: block number Column #02: trial number Column #03: training block [1 = training block, 2 = experimental block] Column #04: saccade direction [1 = right; 2 = left] Column #05: Fixation time jitter [1:36 which corresponds to 36 values from 500 ms to 800 ms from a uniform distribution] Column #06: stimulus change side [1 = upper half; 2 = lower half] Column #07: task type [1 = saccade spatiotopic; 2 = saccade retinotopic; 3 = fixation spatio- and retinotopic; 4 = fixation retinotopic] Column #08: post-saccadic blank duration [1 = 0 ms (no blank); 2 = 200 ms blank] Column #09: response button press [1 = upper half change; 2 = lower half change; -2 = trial aborted due to online rejection criteria] Column #10: response correctness [1 = correct; 0 = incorrect; -2 = trial aborted due to online rejection criteria] Column #11: eye movement online result [1 = Saccade and fixation correct; 0 = saccade incorrect; -1 = fixation break] Column #12: saccade get out of fixation 1 boundary [1 = Yes; 0 = No] Column #13: saccade get in saccade target boundary circle [1 = Yes; 0 = No] Column #14: eye stayed at least 50 msec in 1st saccade target boundary circle [1 = Yes; 0 = No] Column #15: saccade latency too short [1 = Yes; 0 = No] Column #16: saccade latency too short [1 = Yes; 0 = No] ---------- **Eyedata trigger messages:** TRIAL_START ##: Trial ## onset time TRIAL_END ##: Trial ## end time EVENT_ERROR_FIX: failure of the fixation check EVENT_FIX_CHECK: Onset of initial correct fixation EVENT_ONLINE_SACONSET_BOUND: Saccade onset EVENT_ONLINE_SACOFFSET_BOUND: Saccade offset FT_START: fixation target onset FT_END: fixation targer offset REF_START: pre-saccadic target onset REF_END: pre-saccadic target offset BLANK_START: trans-saccadic blank onset BLANK_END: trans-saccadic blank offset PROBE_START: post-saccadic target onset PROBE_END: post-saccadic probe offset
