Randomize app sequence

[楊仲]

Hi,

I made several experiment tasks and I plan to create a Mturk session in which each participant plays them one by one. Each task consists of 30 rounds with each round having at least two pages.I hope that the app sequence can be randomized so that participants face different orders of tasks, but I failed to find the method. I know I can specify the app sequence in setting.py using

SESSION_CONFIGS = [

dict(

name='my_game',

app_sequence=['introduction', 'A', 'B', 'C', 'D', 'payment_info'],

num_demo_participants=2,

),

]

However, is there a way I can randomized the order of 'A', 'B', 'C', 'D' between subjects in the same session?

For example, participant 1 faces ['introduction', 'B', 'C', 'A', 'D', 'payment_info'],

while participant 2 faces ['introduction', 'C', 'A', 'D', 'B', 'payment_info'].

Thanks

Chung Yang

Can you describe the apps A B C D more? Are they related games with different treatment conditions etc?

Hi Chris,

These games are not alike. They are

1. Monty Hall problem (the three door problem)

2. Nim against rational algorithm

3. Race game (counting to 21) against rational algorithm

4. Two-player beauty contest (2/3 of average) against database

Ok, in that case you would need to create multiple session configs, each with a different order of app_sequence, and create multiple sessions.
