List of GLMs for fMRI analysis.

Model	Onset regressors	Parametric modulator	Time (in sec)
1	all Search	(1) Prime, (2) Target words, (3) Search extension	0
	Solution	(1) Prime, (2) Target words, (3) Search extension	0
2	cor Search	(1) Prime, (2) Target words, (3) Search extension	0
	Solution	(1) Prime, (2) Target words, (3) Search extension	0
3	all Search	(1) Prime, (2) Target words, (3) Search extension	last 2
	Solution	(1) Prime, (2) Target words, (3) Search extension	last 2

Note. Time refers to the time in seconds before pressing the search or solution button – onset regressor and parametric modulator are modeled according to the same time, Prime = semantic distance between the prime and the solution word, Target words = mean semantic distance between the target words and the solution, Search extension = semantic distance between the prime compound and solution compound. All Search = all search button presses from all (solved and unsolved) trials, cor Search = search button presses from trials that were later solved correctly. Model 3 was set up only for exploratory purposes.
