Experiment exploring the neural mechanisms of order and content processing in phonological working memory in Italian adults under complex task conditions and varying working memory load. 

In each trial, participants listened to two nonwords and judged if they were the same or different by button press. Nonwords could be consisting of either five (Low load), seven (Medium load),
or nine (High load) CV syllables. Between nonwords, a single-digit multiplication task was inserted to prevent subjects from subvocally rehearsing the first nonword. 


The protocol included:
 
(1) Two control blocks at the beginning of the experiment: pairs of nonwords were always identical and participants had to judge if the voices speaking the first
and second nonword were the same or different. Voices were different in 50% of the trials. 

(2) Test trials: to practice the experimental procedure. At least 5 trials, or until 80% accuracy was reached in the multiplication task. 

(3) Six experimental blocks: the voice speaking both nonwords was always the same. Participants had to judge if the first and second nonword were identical or different. 
There were three conditions, in which the second nonword could be: 
	1) identical to the first one (no change condition, 50% of trials),
	2) present a change in the order of the two syllables surrounding the middle syllable (order change condition, 25% of trials),
	3) present a change in the content of the two syllables surrounding the middle syllable (content change condition, 25% of trials). 
There were two experimental blocks per working memory load: 5-syllable nonwords (Low load), 7-syllable nonwords (Medium load), and 9-syllable nonwords (High load).
Blocks were pseudo-randomized in two loops. The order of the first and second nonword was counterbalanced across participants.
