Cdkn1c ^BACx1 animals show increased motivation to obtain a sucrose reward compared with WT. (a) Average number of trials completed during CRF trials. When minimal work (i.e. a single nose poke) was required to obtain a reward there was no difference in number of trails completed between Cdkn1c ^BACx1 animals and their WT littermates. (b) When the number of nose‐pokes required to obtain a reward increased within a session, Cdkn1c ^BACx1 made more nose‐pokes that WT before stopping (BP). (c) Duration of time between successive nose‐pokes was shorter in Cdkn1c ^BACx1 animals. Average inter nose‐pokes interval. (d) Consequently, average time to complete a trial was shorter in Cdkn1c ^BACx1 animals. Data shown ±SEM. **P < 0.01, ***P < 0.001.
