Note. For the Equal Size Cups condition, the data shown indicate the number of trials in which the larger quantity of food was selected. For the other three columns, the data indicate the number of trials in which the small cup was selected over the large cup.

indicates significant preference for larger quantity over smaller quantity in same-sized cups

indicates significant preference for small cup with large quantity over large cup with small quantity

⁺

indicates significant preference for small cup over large cup with equal quantities

^{^}

indicates significant preference for large cup with large quantity over the small (but fuller) cup with small quantity
