Average complexity values for stimulus pairs

Stimulus type	Average complexity of all pairs	Average complexity of least complex pairs	Average complexity of most complex pairs
Amharic strings	33.53	27.78	39.15
Consonant strings	20.4	17.0	23.7
Nonwords	20.2	15.95	24.05
Pseudowords	20.2	16.45	23.9
Words	20.2	16.35	24.5

Note: Complexity for each pair was computed as the summed value of brushstrokes/character (Changizi and Shimojo 2005) for all 8 characters in each pair. The 20 pairs with the highest complexity values for each stimulus type were labeled “most complex” and the 20 pairs with the lowest complexity values for each stimulus type were labeled “least complex.”
