  1. Shown are mean difference between males and females and the corresponding t statistic for the six outcome measures (intake, licking events, stimulus contacts, duration, licks to stimulus contacts, and stimulus contact duration) across a range of temperatures (37, 24, 10, 2, and -4C). * indicates a significant difference between males and females (P < 0.05).
