Reproductive status biases choice for food vs. sex. Hormone treatment reduced the total number of trials that animals initiated (A), specifically by reducing the number of pellet trials (B). The proportion of mate or pellet trials that animals initiated was altered following hormone treatment (C). Animals initiated more mate trials when hormone primed than when unprimed, and more pellet trials when unprimed than when hormone primed. Changes in the proportion of pellet or mate trials that animals initiated were driven by increases in completed trials, without altering the total number of trials that animals failed (D). Although the total number of failed trials remained unchanged, changes in the corresponding number of completed trials resulted in a significant interaction between hormone treatment and trial type on the proportion of trials that animals failed (E). Data are shown as mean ± SEM. Data points represent within session means for individual animals, n = 8, within subject design. *p < 0.05, **p < 0.01, ***p < 0.001.
