How many trials are unusable?
-
We have 40 subjects, each having done 100 trials in the "active" part of the experiment --> 4000 trials
-
Each of these trials needs to be translated to a "description" format
-
These are two ways in which a trial in description can be considered "unusable" (i.e., not reflecting the "active" counterpart):
-
- When a subject samples only one option, there is no "experienced" description for the other option available. In order not to display an empty description, these trials were replaced in the experiment with the "true" underlying description. this was planned from the beginning and the intention was to simply remove these (predicted to be few) trials from analysis.

- When the bug described in the comment above took place
-
-
The number of dropout trials due to 1) can simply be counted.
-
The number of dropout trials due to 2) can be calculated by comparing the output of this function:
sp_experiment/sp_experiment/utils.py
Lines 169 to 249 in 490d34d
-
namely: What are the return values under parameter
experienced=True
compared toexperienced=False
-
if the returned magnitudes (ignoring probabilities and "98" special magnitudes) are in order regardless of the
experienced=True/False
parameter value, the trial is usable ... else, it is not.
We did such an analysis, and the overall result is:
A proportion of 0.84 (3352/4000) of all trials in the Description task is not mirroring what happened in the Active task.
Thus a huge proportion of trials is not usable. This data is thus not analyzed at all.
