MeliesLab app for iPhone and iPad

This app. is designed for conducting psychology studies on people watching media, including film, TV, or other forms of media. One key application is the measurement of engagement, including the dual-task from cognitive psychology. This activity plays periodic audio tones to the participant while they watch media, who wresponds to by pressing buttons (either high-tone or low-tone). Reaction-times are accurately measured in milliseconds and recorded. The completed trial data is then emailed to the experimenter as a csv file attachment or made available over the google cloud.
