Note. Standard deviations are provided in parentheses. Higher numbers for predictions mean higher numbers of birth category-based predictions; higher numbers for flexibility judgments mean increased flexibility. Mean proportions were compared to the proportion expected by chance (.5) in a series of one-sample t-tests
