3.1.2. Materials
The consent form, demographics form, comprehension test, and
post-questionnaire were they same as in Experiment 1. The only
paper-based materials that differed from Experiment 1 were the
instructions sheets and the Doppler Effect lesson.
There were two instructions sheets given to participants
depending on which expectation condition they were randomly assigned.
The expect test groups were told that they would be expected
to answer questions on the material they studied
