I'm considering using DirectRT for psycholinguistic work. I'd like to know if there is any way to set up a moving window self-paced reading task. There are two issues as I see it - one in the set up of the stimuli, since one wants to be able to break down sentences into chunks in a simple manner. For example, is there a way to use stimuli broken down as follows:

1. In three minutes / the dog / climbed / the tree.
2. For three minutes / the dog / climbed / the tree.

Second is the question of whether the program can smoothly handle the moving window aspect, such that when the subject sees "the dog" it will be in a position to the right of where "in three minutes" was, with placeholder symbols for what has already been seen and what is to come.

Thanks!
