This task was designed using PsychoPy (Version 3.2.3; Peirce et al., 2019) on a Windows 10 operating system. You should have PsychoPy installed to run this experiment. Download and unzip the folder containing the .psyexp executable, the csv files, and the folder of sound files. The PsychoPy experiment requires all of these files to be in the same directory; you can leave the existing directory structure intact after unzipping. To administer the task, you will need the document Protocol_Phonetic_Awareness_CRESULTS_MOSAIC, which includes instructions for setup as well as a score form to record participant responses.
