Figure 1. Sample testing spaces and results from [32] and [39].

A: Depiction of corner views of two of the square arenas tested with human toddlers [32] and mice [39]; B: Percentages of searches at the correct and rotational (the diagonal corner that is featurally/geometrically identical to the correct one) corners for Experiments 1 and 3 in [32] (asterisk indicates above-chance (50%) search); C: Number of trials required to meet a criterion of 75% searches at the correct and rotational corners for mice trained in [39] (asterisk indicates a significant difference between conditions).
