stimuli presentation order logging

[Mysliik]

Hi, is there any easy way how to log the stimuli presentation order? In my experiment, I use stimuli order randomization – using Sequence(rshuffle(X,Y) – and it would be great to have logged the order directly in the data as a separate column. Thanks, Jan

Hi,

All PennController results lines include an EventTime column, and by default all PennController trials report a results line for when the trial started: you can use the value of the EventTime column from those lines to sort the trial by running order (note that the lines int the results file should already be sorted using the values from that column)

Another option would be to do something like that:

Header(
  newVar("runningOrder", 0).global().set(v=>v+1)
)
.log("runningOrder", getVar("runningOrder"))
