<div dir="ltr">I posted this over at the pstnet forums but thought I'd give it a try over here too.<div><br></div><div>Long story short, I'm running an eye-tracking experiment with E-Prime, and I switched over from a two-computer, Tobii Studio/E-Prime setup to a one-computer setup without Tobii Studio (but still using TET and Clearview packages). Now the data file won't display the correct name of the item showing on screen when the data point was recorded. </div><div><br></div><div>In the script, this is done by comparing the RTTime to the slide onset time (in my experiment it is further complicated by my adding variables recorded in the trial list that mark various points in the sound file on the slide, such as verb onset, direct object onset, etc.). On my old setup, everything worked fine. Now I am only getting the name of the item associated with the last-listed condition in the script. </div><div><br></div><div>It seems as if the RTTime is always much larger than the slide onset time, so that the script jumps straight to the last condition. This seems to be related to the fact that the TETTime starts running when the TET server is turned on (so if I were to leave it on for an hour before the experiment starts, my first TETTime data point would be<font color="#000000" face="arial, sans-serif" size="2"> <span style="line-height: 18px;">3600000 ms). If I turn on the TET server and then immediately start running the E-Prime experiment, the problem in the data file goes away. However, I don't want to rely on this method because it is imprecise and means I would have to stop and start the server after calibration and at other parts in the experiment when data isn't being collected.</span></font></div><div><font color="#000000" face="arial, sans-serif" size="2"><span style="line-height: 18px;"><br></span></font></div><div><font color="#000000" face="arial, sans-serif" size="2"><span style="line-height: 18px;">I'm not sure why this is happening, or why the RTTime (which comes from E-Prime) should be decoupled from the slide onset times (which also come from E-Prime). I'd appreciate any insights anyone might have. Thanks!</span></font></div><div><br></div><div><br></div></div>
