Since our main goal was to test the background similarity hypothesis, we pooled the same-background conditions (V–V and Λ–Λ) and pooled the orthogonal background conditions (Λ–V and V–Λ) without excluding any subject, and found that the difference between the two pooled data sets was highly significant ( p = 0.0040, t = 3.62, df = 11). 3.3.
