I am designing a Rapid Visual Information Processing task in which numbers are presented to participants at a rate of one number per 600 ms for 12 minutes. Participants are instructed to respond when 3 consecutive odd or 3 consecutive even numbers are presented on a screen. Responses are deemed correct if they occur up to 1500 ms following the presentation of the target sequences. This means that participants may be responding appropriately to a target sequence at a point in which the target sequence is no longer being presented on the screen.
How can I code correct responses for this experiment?
Thanks for your help,
