Notes

Analysis from the Functional Imaging Analysis Contest (FIAC).

This is a block design experiment with a 2 X 2 experimental design with the following factors:

• Sentence with 2 levels: Same (SSt) vs Different (DSt)

• Speaker with 2 levels: Same (SSp) vs Different (DSp)

giving the 4 following conditions:

• Same Sentence-Same Speaker (SStSSp)

• Same Sentence-Different Speakers (SStDSp)

• Different Sentences-Same Speaker (DStSSp)

• Different Sentences-Different Speakers (DStDSp)

The design also included a 5th condition containing the first sentence pooled across all conditions.
