By default the temporal derivative is added to each main "original"
EV (explanatory variable or regressor). You can see in your model
that 2EVs were generated.
For every EV a parameter estimate (PE) is obtained. By default your
contrast would have been [1 0] so the second one would not be used in
the COPE.
Cheers.
