Hi, I have a task that includes some trials with uncued RT to a left or right arrow. Other trials assess participants' RT to left or right arrows when they have been cued to that side in advance. I am trying to figure out if it is possible to give the participant feedback (e.g., a sound) when they have successfully reduced their reaction time in the cued condition. That is, while the stimuli are being administered, can DirectRT compute the mean for completed trials and include that value in an algorithm for providing feedback. Thanks in advance for your responses.
