Hello all,

I am currently working on a gaze-contingent design with E-prime 3.0 and Tobii Pro Lab using E-prime Extensions for Tobii. My design requires stimuli to start only when fixation of at least 1 second occurs (TETWait forFixation) and stimuli terminate when participant looks away from the screen for longer than 2 seconds. Vidoes are placed in the design as SlideMovie sub-objects.

My stimuli at present are not playing in their entirety, videos play only momentarily, then they skip to the next trial. The SlideMovie sub-object settings are folowing:

Stimulus Slide's Duration is set to 0 which it should be in order for the 'Do Loop' in the GazeContingency Inline to work properly. However, this is what is not allowing my videos to play as the Slide is only being processed for 0 ms (maybe 1 or 2 to actually draw it on screen).

In the SlideMovie sub-object properties, the 'Stop After' is currently set to Yes; the 'End Movie Action' sub-object property is currently set to Terminate, this means that when the movie ends (if the GazeContingency script does not do so first), this will trigger the Stimulus Slide to Terminate. Setting these to: 'Stop After': No and 'End Movie Action': none results in the following error:

'Cannot Set Clip List'

Error number: 11087

Any help with this error would be greatly appreciated.

Also, would anyone be willing to either :

Share samples of similar of gaze-contingent designs; or

point me to the right teachnical support options (are paid plans worth it?)/E-prime materials?

Thank you in advance

Tatiana
