This repository contains modified versions of the Flanker, Odd-man-out, and Simon tasks implemented in *OpenSesame* (Mathôt et al. 2021), as well as a modified auditory version of the digit span task, implemented in *SoSci* Survey (Leiner, 2019). For the *OpenSesame* version tasks, first, you need to download the freely available *OpenSesame* program/application (https://osdoc.cogsci.nl/) on your local computer. Then, you need to download the *OpenSesame* code for a corresponding task (see different folders) from this repository. Please, note that the folders will be downloaded as .zip files. Once you unzip them, you can click on the *OpenSesame* icon, and the interface of the experiment will pop up. Now, you can directly run the experiment. Note, that task instructions are written in German. Thus, in case your participants speak another language, you will need to translate them accordingly. For the *SoSci* Survey version of digit span, you need to create an account in the https://www.soscisurvey.de/ (free). Then, you need to download the html code of this repository, and import it in your account as a new project. If this does not work, please, get in contact with me to share with you the template directly in your *SoSci* Survey account. In any case, please, contact me for the audio files. Thanks to Christine Röhr for her help with setting up the *SoSci* Survey version of the digit span task.
