Holeboard is used as a spatial learning memory test in which rodents learn to discriminate baited from unbaited holes in the open field for a food reward. The task provides measures for reference memory errors (when mice poke into unbaited holes for food reward) and working memory errors (repeat visit to a baited hole from which the food reward has already been collected).
The total number of errors (reference and working memory errors) decreased over 4 days of training.

The amount of time for mice to complete the task decreased over 4 days of training.
