Hi all,

I created a primed lexical decision task, where an image is primed right before the decision word. In the lab, this file runs smoothly, but using the online version, it seems to depend on the computer the participant is using. Yes, the file opens, but whereas it runs smoothly on my own PC's (Windows Vista & 8, Internet explorere & Chrome), the loading times on some other computers is very long. The task should be around 5 minutes in length, but I had some respondents breaking it halfway the task off, and the running time was by then already 12 minutes! This difference cannot be due to slow reaction times, since they are cutoff after 3 seconds. I got feedback that the intertrial interval is quite long and is becoming longer as the task continues.

Does anyone know what can cause this problem, and what could solve it?

Btw: here the link to the file: http://research.millisecond.com/friescamp/ApSientje14.web
