DESCRIPTION
In the delayed reward task, animals make a choice between a small, immediately available reward, and a large reward that is available after a delay. This version consists of several blocks with a number of trials inside. The first two trials wityhin each block are always forced trials. There is a maximum of 10 trials per block. There is no maximum number of blocks. The code can easily be adapted to work with nose-poke holes instead.

This condensed version of the delayed reward task is nothing more than a quick hack of the original delayed reward procedure. The standard number of trials per block was lowered to 2 forced + 4 choice, while the number of blocks was decreased to 5 from 6. In addition, trial duration is now determined by adding a constant to the long delay for the current block. The earlier blocks are therefore shorter than the later blocks.
