Room Assignment
This is an experiment powered by Empirica. Through this experiment we attempt to answer the question: How does team composition affect team performance?
In this experiment, participants are asked to assign N students into M rooms to maximize utility while respecting certain constraints. The task difficulty can vary in complexity levels:
- High complexity: Assign 9 students to 6 rooms given 8 constraints
- Low complexity: Assign 6 students to 4 rooms given 2 constraints
When the task is performed in groups then:
- All participants can do the assignment simultaneously, however, ony onestudent can be moved by one player at any given time (i.e., locking thestudent being moved, but the others are free to be moved).
- Participants can chat freely using the in-experiment chatting system.
- All events (i.e., which student being assigned to which room etc) will belogged and announced in the experiment as they happen.
In the planned experiment, in step 1 each participants will be asked to complete a number of room assignment tasks and other test questions (e.g., read emotions from eyes tests) individually. This will allow us to determine 3 attributes about the individual:
- Ability: measured by the performance in the game.
- Social Perceptiveness (SP): Measured through
- Cognitive Style (CS): an in-task measure of problem-solving style (e.g.,intuitive versus analytical).
Then, in step 2, we randomly construct teams of 3 participants.
You and a group of friends can play with this experiment as we ran it by following these instructions (assuming you have Meteor installed):
- 1.
git clone https://github.com/amaatouq/room-assigment
- 1.Go into the folder with
cd room-assigment
- 2.Install the required dependencies
meteor npm install
- 3.Edit the
admin
password in the settings filelocal.json
to something you like. - 4.Run the local instance with
meteor --settings local.json
- 5.
- 6.login with the credentials username:
admin
and the password you have inlocal.json
- 7.Start a new batch with whatever configuration you want (see the example configuration).
First, you have to enter the Configuration mode instead of the Monitoring model in the admin UI.

This will allow you to configure the experiment: Factors, Lobby, and Treatments. Now, you have the option to create your own configuration (see below) or load an example configuration by clicking on
import
and then choosing the file ./example-config.yaml
. Loading the example configurations will choose some example values for the factors (i.e., independent variables), lobby configuration, and few treatments.Now, you can go back to the Monitoring mode:

Now the Batchs tab make sure you add a new batch, add the treatments you want, choose your lobby configurations, and then start the batch.

Go to http://localhost:3000/ and enjoy! If you don't have 3 friends to play with you, you always can use the
new player
button in development (for more details see this), which can add an arbitrary number players to the experiment while staying in the same browser (i.e., no need to open different browsers).
