Repeat_cycle

This plug-in allows you to repeat cycles from a loop. Most commonly, this will be to repeat a trial when a participant made a mistake or was too slow.

For example, to repeat all trials on which a response was slower than 3000 ms, you can add a repeat_cycle item after (typically) the keyboard_response and add the following repeat-if expression:

response_time > 3000

You can also force a cycle to be repeated by setting the variable repeat_cycle to 1 in an inline_script, like so:

repeat_cycle = 1
