Multiple Responses Per Trial
Required Experiment Builder Version: 1.10.1630 or higher
EyeLink Required: No
Type: Complete Example
Difficulty Level: Easy
This example demonstrates:
In this example, the participant is instructed to press the spacebar a specific number of times for each of 12 trials. The number of presses per trial is set in the Trial Data Source, so each trial can be set to require an independent number of responses. The display screen lists the current trial (# / n) to mark overall progress, and displays the number of presses still required for the given trial. The displayed number of required presses updates after each press, through to 0. Once 0 is reached, the display remains for 300 ms before the trial ends.
**Additional detailed information about the project is given in the notes section for most nodes. To see notes for a given node, either mouse over that node or click on it to display the notes window. If the notes window is not visible, go to the "View" drop down menu in Experiment Builder, select "Properties", and check "Note".
