I’ve looked around online but haven’t been able to find another thread with this problem. I currently have loops set up in Builder that sequentially display pictures that it pulls from a hyperlinked Excel file. Each picture is set to be displayed for 0.5s, during which a participant is to make a response (Go/No-Go task). Before each picture is an ISI/fixation point that lasts for 1.5s.
Sometimes, the loops run perfectly fine and each picture flashes on-screen for 0.5s. Other times, however, some pictures flash too quickly to be really seen/make a response. There doesn’t seem to be a pattern to which pictures flash too quickly (it’s not the same pictures flashing too quickly every time this happens). All pictures are in .JPEG format.
I can’t seem to find anything in the code that would cause this mistake. In Builder, the timing of everything is set up as I specified above. Additionally, like I said, sometimes it runs with no problems. Any thoughts as to what could be causing this? Thanks!
