- Download required video clips from movie_clips.zip
Extract into the
data
directory.
The software requires two sets of input files. There should be a set of text files present under data/stimulus_orderings
that indicate the display order of video clips for different phases of the experiment. In addition, there should be a set of video clips (stored as raw .npy files). These clips must be downloaded and extracted into the data folder from movie_clips.zip
-
For the random stimulus order (days #0 and #5):
- there are 4 difference choices of a 2 sec duration stimulus
- movie clip A
- movie clip B
- movie clip C
- a constant grey screen, X
- these will be displayed in a randomized order.
- this order will be exactly the same on day #0 and day #5.
- there will be 525 repeats of each of the 4 stimuli.
- there are 4 difference choices of a 2 sec duration stimulus
-
For the sequence stimulus order (day #1 – #4):
- the 3 movie clips are shown in the same repeated order, ABC, for 50 minutes.
- this will result in 500 repeats of this movie clip sequence.
- in the last 20 minutes, the stimuli will be shown in a random order with the grey screen intermixed, as on days #0 and #5
- a different random sequence will be chosen and kept the same across days #1 – #4.
- this will result in 150 repeats of each of these 4 stimuli.
