Text stimuli are not centred

If this template helps then use it. If not then just delete and start from scratch.

What are you trying to achieve?:

I’m trying to run a simple experiment in which words have to be learned. The words should be displayed in the centre of the screen and measure 4 cm in height.

What did you try to make it work?:

I set my screen settings:

  • viewing distance = 75 cm
  • screen size: 34 cm
  • pixel dimensions: 1920 x 1080

What specifically went wrong when you tried that?:
if setting the stimulus size to 4 cm the displayed size is 3 cm. If I set 5 cm then the words are shifted right off centre. The same happens when using norm, or deg.

I also tried inserting a code block and explicitly set the text position to centre and that did not help either.

I’m wondering what I failed to consider. Can anyone help?

Thanks!
