title: ANIMAL COGNITION. Response to Comments on "Number-space mapping in the newborn chick resembles humans' mental number line".
abstract: Mangalam and Karve raise concerns on whether our results demonstrate a mental number line, suggesting auxiliary experiments. Further data analyses show that their methodological concerns are not founded. Harshaw suggests that a side bias could have affected our results. We show that this concern is also unfounded.
