Doing things in sequence
The sequence item has two important functions:
- It runs multiple other items one after another.
- It determines which items should, and which shouldn't, be run.
sequences are run from top to bottom; that is, the item at the top is run first. The order of a sequence is always sequential.
Run-if statements
You can use run-if statements to determine whether or not a particular item should be run. For example, if you want a display to be presented only if a participant has made an incorrect response, you can set the Run-if statement for that item to:
[correct] = 0
If you leave the run-if statement empty or enter 'always', the item will always be run. Run-if statements use the same syntax as all OpenSesame conditional statements. For more information, see:
Run-if statements only affect which items are run, not which items are prepared. Phrased differently, the Prepare phase of all items in a sequence is always executed, regardless of the run-if statement. See also:
