Hi,

The trial duration is set to 2500 milliseconds. A correct look is marked when the participant looks longer to the target image than the distractor image on a given trial.

/ aoidurationthreshold determines the time a given participant must gaze within a specific area of interest before a hit is scored / that gaze is scored as a response.

The problem with this idea is: How is the given trial supposed to terminate, i.e., accept a gaze at an object as a response if there is no threshold of any kind specified?

<trial puppypuppy>
/ ontrialbegin = [values.marker = (picture.puppyleft.currentindex * 100) + picture.puppyright.currentindex;]
/ ontrialbegin = [port.marker.setitem(values.marker, 1);]
/ stimulustimes= [1=puppyleft, puppyright, marker]
/ inputdevice = eyetracker
/ validresponse = (puppyleft, puppyright)

/ screencapture = true
/ draw = pen
/ showmousecursor = true
</trial>

Hi,

Where can I find the documentation for the "aoidurationthreshold" attribute for the eyetracker element ? I see it used in the preferential looking example script, but can't seem to find the documentation/syntax for the attribute. I'm trying to use the preferential looking script but I want to record the total looking time to each image on each trial rather than having it time out after a threshold is reached. Any help is appreciated!

Thanks,

SD
