Effects of delay and reward on the performance of isolation rearing on TDRT in socials and isolates. a Both groups exhibited a similar sensitivity in choice behaviour in the condition when delay was removed from the task context (a). b When the reward ratio was reduced, both groups exhibited a choice preference for small, but immediate reward (b). The vertical bar represents the standard error for the difference between means (SED) taken from the error terms for the interaction between factors. See legend of Fig. 1 for detail
