This folder contains the experiment files and materials to run the test battery and collect the data for the study "Is executive control related to working memory capacity and fluid intelligence?" from Rey-Mermet, Gade, Souza, von Bastian and Oberauer.
The test battery was programmed using Tatool (von Bastian, Locher, & Ruflin, 2013). To run the battery, the following steps are necessary:
- double-click on the file named `uzh-inhibitionwmc-1-jfx`
- create a user (if necessary)
- select you user name and click on "ok".
- click on the `add` button
- select `module from the local file`
- search and select the folder `resources` in your folder path
- select the xml files you want to start and click on ok
- click on `start` in the new window
Participants were tested during two sessions of approximately 2-2.5 hours each (including breaks after every block and a longer break in the middle of each session). To control for practice effects, task order was counterbalanced across participants. This results in 4 xml files including the following tasks:
- `order1.xml`
1. demographic questionnaire
2. letter sets test (fluid intelligence)
3. arrow flanker task (executive control)
4. numerical updating task (working memory capacity)
5. stop signal task (executive control)
6. spatial complex span task (working memory capacity)
7. Simon task (executive control)
8. Raven advanced matrices test (fluid intelligence)
9. number Stroop task (executive control)
- `order2.xml`
1. BDI questionnaire
2. relationships test (fluid intelligence)
3. color Stroop task (executive control)
4. spatial updating task (working memory capacity)
5. locations test (fluid intelligence)
6. timer rating task
7. numerical complex span task (working memory capacity)
8. antisaccade task (executive control)
9. syllogisms test (fluid intelligence)
10. letter flanker task (executive control)
- `order3.xml`
1. demographic questionnaire
2. letter flanker task (executive control)
3. syllogisms test (fluid intelligence)
4. antisaccade task (executive control)
5. numerical complex span task (working memory capacity)
6. timer rating task
7. locations test (fluid intelligence)
8. spatial updating task (working memory capacity)
9. color Stroop task (executive control)
10. relationships test (fluid intelligence)
- `order4.xml`
1. BDI questionnaire
2. number Stroop task (executive control)
3. Raven advanced matrices test (fluid intelligence)
4. Simon task (executive control)
5. spatial complex span task (working memory capacity)
6. stop signal task (executive control)
7. numerical updating task (working memory capacity)
8. arrow flanker task (executive control)
9. letter sets test (fluid intelligence)
Please note that the BDI questionnaire (i.e., Beck Depression Inventory II; Hautzinger, Keller, & Kühner, 2006) is not included in the present version of the test battery due to copyrights.
Then, you have to enter the following information:
1. `code` (participant ID, > 99 and < 10000)
2. `Ausbalancierung_Batterie` (1 = "order1.xml"; 2 = "order2.xml"; 3 = "order3.xml"; 4 = "order4.xml")
If you want to do only some tasks, please go to the folder `crash` or `only_one_task` in the folder `resources`. Then, you can select the xml-file of interest.
In order that the test battery works properly, please change nothing in the folder structure.
The data are saved in CSV format in a folder called "data". A data file is created for each participant in each session.
At the end, the test battery stops and you have to click on "exit" to shut down Tatool.
To exit the test battery before the end, please press "esc".
All materials and instructions are in German.
