Temporal reward discounting describes the decrease of value of a reward as a function of delay. Decision-making between future aversive outcomes is much less studied, and there is no clear decision pattern across studies; while some authors suggest that human and nonhuman animals prefer sooner over later painful shocks, others found the exact opposite. In a series of three experiments, Long-Evans rats chose between differently timed electric shocks and rewards in a T-maze.

Rats show mutual-reward preferences, i.e., they prefer options that result in a reward for both themselves and a conspecific partner to options that result in a reward for themselves, but not for the partner.

Rats emit vocalizations in the ultrasonic range (ultrasonic vocalizations; USVs), of which 50-kHz USVs could communicate positive affective states and induce approach behavior in conspecifics, whereas 22-kHz USVs might signal negative affective states and potential threats. Listening to 50-kHz USVs can be rewarding, but it is unknown which brain mechanisms are responsible for the assignment of reinforcing value to 50-kHz USVs . The behavioral responses induced by listening to 22-kHz USVs are heterogeneous and need further characterization.
