The iOS app "C2 Stroop Task" is intended for those who are interested in cognitive psychology, those who are learning cognitive psychology, and those who are researching it. * The effect of the Stroop task appears as a difference in time to perceive text color in the following two cases, for example. ・text color = red, text = "red" (compatible) ・text color = red, text = "green" (incompatible) This app allows you to see the Stroop effect numerically. The iOS app "C2 Stroop Task" records the response time of a stroop 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. Language settings can be made by editing the words for each color, so any language that can be entered from the keyboard can be set. You can set the intertrial interval, number of tasks, compatibility rate, color selection, position, size, background color, whether to shuffle the answer buttons, etc. [details] https://app.brain-workout.org/strooptask-e/
