Hi all,
I hope anyone can help me with a task design issue.
We are planning to conduct a study on reading comprehension. Participants will read 10-sentence stories. The stories will be presented sentence by sentence, self-paced. The manipulation we're interested in is on the 8th sentence (2x2 design with 10 stories in each cell). There will be jitter between stories (around 7-14 sec), but unfortunately we cannot introduce jitter between sentences because it will disrupt the reading processes we're interested in.
We're planning to use a model with 6 task regressors (one regressor for sentence 1-7, one regressor for each condition on sentence 8, and one regressor for sentence 9-10).
Does this make sense? How big a problem is it that we cannot use jitter between the sentences? We're running a pilot scan next week, so all suggestions are welcome!
Thanks very much in advance,
best wishes,
Dietsje
