The iOS app "C2 Flanker Task" records the response time of a flanker task (task conflict) in milliseconds. Response time is the time from when the task is displayed to when the answer button is touched (touchdown). The recorded data can be output to a CSV file and read into a spreadsheet application such as Excel. In addition to the orthodox flanker task, you can also check the effect by changing the presence or absence of coloring, the brightness of the background, the shape of the arrow, and so on. * The effect of the flanker task appears, for example, as the difference between the time to recognize the direction of the central arrow of →→→→→ and the time to recognize the direction of the central arrow of ←← → ←←.
