Inquisit Language Reference
The posttrialsignal attribute specifies that after running a trial, Inquisit should wait for a signal from an external device before moving on to the next trial.
<likert> <openended> <slidertrial> <trial>
or/ posttrialsignal = (mouse, stimulusname)
or/ posttrialsignal = (mouse, mouseevent)
One of the following values:
|signal||An integer representing the numeric signal to wait for. If the modality is keyboard, this is the scancode of the key.|
|mouseevent||Any of the following mouse events.|
|stimulusname||The name of a visual stimulus element defined elsewhere in the script.|
This is useful for requiring a second confirmation response from subjects before proceeding to the next trial, or for synchronizing Inquisit with an external device such as an EEG.
The following trial waits for a signal value of 8 on the COM1 port before advancing to the next trial:
/ stimulusframes = [1=sometext]
/ validresponse = (57)
/ posttrialsignal = (com1, 8)
