Adding behavioral experiment files! deployment_v2.csv is the raw responses from meadows, experiment_v4.csv is the dataframe with all the trial information specified for the experiment, filtered_responses.csv is my preprocessed results spreadsheet that has been merged with the experiment spreadsheet and can be used for analysis. human_trials_mindeye2.ipynb is the code to create the experiment dataframe, filter and process the results, create the filtered_responses spreadsheet, and run analysis. stimuli_v4.zip contains all the stimuli corresponding to experiment_version 4, which is the final version I deployed. brain_diffuser_failures_tiled.zip contains all stimuli for experiment 3 where the subject didn't pick the mindeye2 reconstruction.
