The simultaneity judgement task data is stored as .txt files therefore no special software is required to view them. The emotion recognition task data is also stored as .txt files. However, a MATLAB program is required to process these files and get further data of interest (average accuracy and reaction time for correct responses). The details of data processing have been provided in the Read-me-first.txt under the emotion recognition task folder. The code of the MATLAB program used for data processing (Emotion_analysis.m) is also included in the same folder.
