Determining the correct response based on whether a stimulus was previously presented

I’ve created a sample experiment that does the following:

  1. Contains two stimulus lists, each with ten items.
  2. Presents a random selection of five items from the first list.
  3. Takes those five items and randomly mixes them with five from the second stimulus list.
  4. Correct responses are determined based on whether the stimulus has been previously presented.

This sample experiment was created in response to this thread and can be downloaded by clicking here.
