Hi
I am trying to make the same “masked self-paced reading task” too.
And I did read through the posts you linked and other people trying to do similar things in the discourse page.

But, what completes this task is that the lines masking the words in the sentence should not move just like the gif above (and below).
This is why it is called “moving window” in linguistics field I believe. I can make sentences masked with dashes and collect separate RTs from previous links but I cannot make those masking dashes stay still while I move through the sentence. It seems like it is aligning itself automatically but I couldn’t come up with an idea to set it still.
Would there be a solution to this problem?
Yours sincerely,
Kyung
