Note. Values above the diagonal represent statistics in the high-performing group, whereas values below the diagonal represent statistics in the low-performing group. Sample sizes for correlations range from 419 to 517 in the low-performing group, and from 492 to 498 in the high-performing group. F = flowers; X = mixed; RT = reaction time.
