* All pupil data have been preprocessed
Columns:

pupil_resp_d_clean          (pre-feedback interval 1/2, response-locked pupil [3,6] seconds, 'clean' refers to time window after IRF, RT *removed* via linear regression)
pupil_resp_d_clean_RT       (pre-feedback interval 1/2, response-locked pupil [3,6] seconds, 'clean' refers to time window after IRF, RT has *not* been removed)
response                    (1=up, 0=down motion direction)
rt                          (reaction time in seconds)

isi                         (inter stimulus interval, between response and feedback)
ITI                         (inter trial interval, from feedback onset to start of next trial)
long_isi                    (True when isi greater than 5.5)
long_ITI                    (True when ITI greater than 5.5)
