Figure 2: Significant Comparisons Between Adjacent Categories in the Rank and Inference Task for Itzaj Maya and Michigan Students.
Results include all life forms and biological properties, showing "all" (versus "few" or "none"), "none" (versus "all" or "few") and combined responses ("all"=3, "few"=2, "none"=1). 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.
