Table 3. Summary of results.
The number of trials required to learn to associate food with the gold tube (color test; min. 17 out of 20 trials correct) and to become proficient at dropping stones down the platform apparatus (stone drop training; number of non-proficient stone falls plus 30 proficient stone drops); total number of correct choices/total number of choices and p-values from binomial tests for experiments 1–5 (the Bonferroni–Holm correction was applied to Experiment 2).
