Table 2.

Calculated t-contrasts for the different morpho-syntactic aspects.

	fMRI contrasts
	Exp. 1: healthy speakers	Exp. 2: agrammatic speakers
Completeness	Simple complete CLUs in the 3W-condition vs. simple CLUs that are incomplete due to a missing verb in the 3W-condition	Simple complete CLUs vs. simple CLUs that are incomplete due to a missing verb
Complexity	Complex complete CLUs in the NAT-condition vs. simple complete CLUs in the NAT-condition	Only A1: complex complete CLUs vs. simple complete CLUs
Morphology	Simple complete CLUs in the NAT-condition vs. simple complete CLUs with morphological errors in the 3W-condition	Morphologically correct CLUs vs. CLUs with omission and/or substitution of closed class words
Morpho-syntactic planning	Pauses/interjections between CLUs in the 3W-condition vs. pauses/interjections between CLUs in the NAT-condition	No comparable contrast

Exp., experiment; CLU, clause-like unit; A1, patient A1.
