Is there a way to tell Superlab to randomly pick from a stimulus list, but not to pick the same picture more than once during an experiment run? there is an option like this for
Instead of letters, each trial is associated with an event that has a unique stimulus list (~20 pictures of a particular kind of animal). Each time the trial is presented, I would like Superlab to show a picture that it has not shown already this experiment run.
Thanks for the reply. Our task repeats each individual trial several times (it is based on the one you created that randomly selects a subset of trials for each ‘round’).
By necessity, the same trial will be repeated many times. Each trial has a unique stimulus list associated with it. For example, Trial 1 is linked to an event with a stimulus list containing a bunch of pictures of lions. Trial 2 presents a picture of a walrus from a stimulus list of several walrus pictures, etc. I am looking for a way to make sure that once each picture is presented, it is not presented again.
Apologies for the delay … I usually get an email when a new reply is posted but didn’t this time.
The experiment is attached. It’s based on the other task you helped me build. In this task, Superlab presents between 3 and 6 animal pictures per trial that the subject. the subject clicks a button on screen to ID the name of the animal (e.g., lion, walrus). Then, the subject sees a sentence and clicks a button to say whether the sentence is true or false. After 3-6 animals/sentences, it asks the subject to recall all of the animals they saw that trial.
The sentences pull from a stimulus list, and I can’t figure out how to tell Superlab not to repeat the same sentence after it’s been seen by the subject.
The animals also pull from stimulus lists (1 list per animal type), and again I don’t see how to keep Superlab from presenting a picture file that has been shown earlier in the task.
