Table 2. The two lists were balanced on the most important psycholingusitic parameters, including the natural logarithm of word frequency, familiarity, letter and syllable length and word concreteness (according to the Wilcoxon signed-rank test).

	List 1 (mean, SD)	List 2 (mean, SD)	Wilcoxon test
Word frequency	1.37 ± 0.77	1.39 ± 0.65	p = .94
Familiarity	4.38 ± 0.94	4.45 ± 0.92	p = .79
Letter length	7.39 ± 1.5	7.42 ± 1.3	p = .97
Syllable length	2.38 ± 0.6	2.47 ± 0.63	p = .26
Concreteness	0.63 ± 1.0	0.59 ± 0.99	p = .74
