Figure 1: Rank and Inference: Comparing the Willingness of Itzaj Maya and Michigan Students to Make Indiuctions Across Folk-Biological Ranks.
Results include all life forms and biological properties, showing the proportion of "all" (black), "few" (checkered) and "none" responses (white). Main diagonals represent inferences from a given rank (premise category) to the adjacent higher-order rank (conclusion category): V(arietal) -> S(pecific), S(pecific) -> G(eneric species), G(eneric species) -> L(ife form), L(ife form) -> K(ingdom). Moving horizontally within each graph corresponds to holding the premise constant and varying the conclusion: e.g., V -> S, V -> G, V -> L, V -> K.
