| Outline of Final Research Achievements |
We explained systematicity in terms of the category theory concept of universal constructions. Experimentally, we tested a theoretical implication that failure of systematicity derives from a cost/benefit trade-off for the universal construction. Participants learned two series of cue-target pair maps whose underlying structures were either products (universal construction), or non-products (control). Each series was learned in either ascending or descending order of size: number of unique cue/target elements constituting pairs. Only performance on the product series was affected by order: systematicity was obtained universally in the descend group, but only on large sets in the ascend group. Consistent with the theory, the results suggest that learning small maps directly, without reference to the underlying product, may be perceived as more cost-effective, i.e., acquisition of a universal construction, hence systematicity, depends on an empirical cost-benefit trade-off.
