This is a data sheet used in Discrete Trial Training (or Discrete Trial Instruction) programs.
This data sheet consists of six sessions, made of:
9 trials with 1 response and 3 stimuli (Hence the name "9T-1R-3S")
All stimuli are presented together (Hence the "Sim")
The target response is alternated between the three stimuli (Hence the "Alt")
This data sheet has six sessions on one sheet, and allows for space for additional notes for each session. And includes all possible "% correct" calculations at the bottom of the sheet.
Within each session, the three stimuli are presented together on the Left, Center and Right. Rotating through the trials is easy, as the most right stimuli is then placed on the left, and everything shifts one to the right. This allows for equal distribution of every stimuli into the three locations. The target stimuli is highlighted so the staff will know which stimuli to target. Each of the three stimuli is targeted three times per session, and each is targeted once in the right, center or left. By doing this, positional bias is accounted for.
This data sheet can be used for:
-Matching stimuli (ex: pictures to objects)
-Touching stimuli (ex: Touching objects)
-Directions with multiple items (ex: drum/maraca/bell -> shake bell)
