Python re-implementation of the WMC battery described in Lewandowsky, S., Oberauer, K., Yang, L. X., & Ecker, U. K. (2010). A working memory test battery for MATLAB. Behavior research methods, 42(2), 571–585. https://doi.org/10.3758/BRM.42.2.571

This implementation is a minute reproduction of the original MATLAB implementation and uses the same file output format. This way the accompanying R-script of the original implementation can still be used for data processing.

• implementation limited to the following tasks: Memory Update, Operation Span, Sentence Span, and Spatial Short-Term Memory (left out Choice Reaction Test, Task Switching, and Word Recognition as not referenced in paper)
• random seed can be either set explicitly or will be automatically determined by the session name / subject id
• Spatial Short-Term Memory trials are dynamically generated for each new experiment run
• corrections in chinese language files (instruction pages, experiment messages and sentences for Sentence Span task)

You may need to put .local/bin in your PATH by adding this to your .bashrc in your home folder:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

After that, create a new terminal and close the old one to reload the configuration.

sudo apt-get install psychopy python3-pip python3-wxgtk-webview4.0 libxcb-xinerama0

pip3 install --upgrade pip
pip3 install -r requirements.txt
pip3 install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-20.04 wxPython==4.1.1

For Chinese font support:

sudo apt-get install fonts-noto-cjk

pip install psychopy==2020.2.10 pygame wxPython numpy pandas scipy dotmap pyyaml

For Chinese, please download and install the required font package 'Noto Serif CJK SC': https://www.google.com/get/noto/

The support for font install : https://www.google.com/get/noto/help/install/

pip install psychopy==2020.2.10 pygame wxPython numpy pandas scipy dotmap pyyaml

python3 wmc_ubuntu.py

python3 wmc_mac.py

python3 wmc_windows.py

You can quit the experiment by pressing F12.

It is advised to mark the arrow-keys on your physical keyboard for the Operation Span and Sentence Span tasks. You can configure the keys in the yaml-config files in the config folder (key_map field).

You can test your language files by running the following command:

python3 test_language.py

You will move through all experiment messages, instruction pages, a summary for sentence span sentences and all sentence span sentences with the respective label. For the sentence summary, moving on is possible only after one second has passed to prevent accidental skipping.
