This paper proposes a new constraint schema for the Obligatory Contour Principle (OCP) in order to model scalar interactions between similarity and proximity observed in gradient dissimilation. The OCP is newly formalized as a family of markedness constraints that incorporate various degrees of interaction between two continuous scales. Scales are formalized based on stringently-defined scalar degrees and their interactions are formalized as one-to-one logical conjunction of scalar degrees across two target scales. Considering the relationship of similarity and proximity in the OCP—similarity is primary and proximity is secondary—each markedness constraint of the OCP is defined as a prohibition of a pair of target elements if they show a specific degree of similarity or a type of interaction between similarity and proximity. The case study of Swedish high tone dissimilation shows that the proposed OCP schema can model complex patterns of gradient dissimilation which cannot be explained by the traditional OCP.
