Hi all,
My experiment involves two rectangles (polygon components) moving towards each other over an image component. Unfortunately, for the first trial of my experiment the components of my experimental routine (called trial) are not presented or are presented larger than intended. For subsequent trials these components are presented as intended.
I am not sure if these two code components are contributing to this issue:
The images to be displayed in my image component are specified in the “begin experiment tab” of a code component.
The starting position of my top rectangle is specified in a condition file (as this changes with each condition). The bottom rectangle is always supposed to be opposite this top rectangle, and this is done with this code in the ‘begin routine’ tab of a code component:
TopX = StartPos
BotX = TopX * -1
I have tried the following things to fix this issue, but they did not work:
I added my images into the additional resources section of the online tab.
I deleted the routine preceding my trial routine, but there were no improvements in performance.
I tried building an ISI Into the trial routine and pre-loading my images during the ISI, but this did not work, as there are multiple images that change each frame.
Does anyone have any ideas what might be causing only the first trial of the routine to play up? Does anyone have any fixes?
Thank you in advance for any assistance!
