What are you trying to achieve?:
I am trying to display a fixation cross for 350ms before the onset of my stimuli. I have two sets of stimuli: images of bottles and images of words. There are multiple blocks in my experiment. In the first block, only the bottles are shown. In the second, only the images of words are shown. Then in the third, all the images are shown together. The length of these blocks and included stimuli are determined via a list multiplier in a code component. The fixation cross only seems to be displayed before the images of words, not bottles, even when they are shown together rather than separately.
What did you try to make it work?:
I have tried running just the images and fixation cross in a separate experiment, which works fine. It just seems to be in my particular experiment that the fixation cross will not be displayed before the bottle images. I have also tried swapping the bottle images in place of the word images, but that also did not make a difference.
Could anyone shed any light on why this would be happening?
