only marginally significantp = 0.059
Compared to the no-contrast condition, the increase triggered by the object contrast was only marginally significant (χ 2 = 3.6, df = 1, n = 76, p = 0.059), whereas the decrease triggered by the liquid contrast was significant (χ 2 = 37.2, df = 1, n = 73, p < 0.001).
