From: Horses with sustained attention follow the pointing of a human who knows where food is hidden
The proportion of correct choices in low and high attention-loss horses. The statistical values indicate the results of the statistical analysis investigating whether the choice was significantly biased compared to a chance level of 0.5 (exact binomial test, n = 18), and investigating whether there were significant differences in the proportion of correct choices of low and high attention-loss horses (Fisher’s exact test, n = 18 for each). **P < 0.01, *P < 0.05.
