run task until user input

[Paul Groot]

Jim,

You could add a small inline script after the image object to terminate the
active list(s) after pressing a specific key. E.g.:

if StrComp(Stim.RESP, "X",1)=0 Then
    TrialList.Terminate
    BlockList.Terminate
End If

You should call the Terminate function on all active lists and replace the
object names with the object names used in your script.

In some cases it is more convenient to use the GetUserBreakState() function
instead of defining a specific key:

If GetUserBreakState() <> 0 Then
  ...
End IF

This will be triggered when pressing Ctrl+Shift.

Best
Paul
