“…Beyond supporting computations of object tracking and numerical systems, linguists, psychologists, philosophers and mathematicians routinely explain human language, logic, and mathematical knowledge via appeal to set and/or lattice theoretic structures (e.g., Barner & Snedeker, 2005;Chierchia, 1998;Link, 1998;Quine, 1963;Russell & Whitehead, 1927). To determine why only humans exhibit these capacities, it is essential to explore not only linguistic contributions to their emergence, but also to document possible non-linguistic conceptual precursors.…”
