Variable Number of Multiple Responses in Each Trial
Required Experiment Builder Version: 1.5.58 or higher
EyeLink Required: YES
Type: Complete Example
Difficulty Level: Easy to Intermediate
This example illustrates:
Each trial allows for the collection of multiple mouse clicks from the participant before a key on the keyboard is pressed to indicate termination of the trial. Each trial displays a page of text to the participant. The participant may be asked to read the text normally and click the mouse each time they encounters a certain letter. Thus the participant will click the mouse a variable number of times. Each click is logged to the EDF file and at the end of the trial the total number of clicks is logged to the EDF file.
**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".
