I am trying to program a frequency task in which subjects hear a randomly selected word. They are asked to hold this word in memory while a set of 6 words is presented. The set of 6 words includes 1, 2, or 3 instances of the randomly selected target. How can I tell DirectRT to repeat this randomly selected stimulus within the same trial? Moreover, can DirectRT randomize the positions in which the target and foils are presented (while also randoming the order or trial presentations within groups)? Thank you!
