I have some data from the Change Blindness task (http://www.millisecond.com/download/library/ChangeBlindness/)
I understand the task and what it's measuring but I cannot decode the variable names Inquisit in outputting nor can I find any documentation explaining the variables.
For each trial I get the following column names:
values.prechange3_hits, values.prechange3_fas, expressions.prechange3_diff,
values.postchange3_hits, values.postchange3_fas, expressions.postchange3_diff
I understand the pre and post trials, "diff" is just "hits - fas".
I cannot figure out what "hits" & "fas" are though.
Hits looks like it could be the serial position of the item that was removed/replaced and fas is the subject response, correct of false. However Fas occasionally takes the value of 2 (almost always 0 or 1 otherwise). These aren't intuitive, abbreviations or acronyms though which makes me think it must be something else.
Looking for an "AHA" moment :)
