This paper aims to show that the perceptual inputs from the grammatical alternations in Korean reflect the cognitive spatial representation of container image schema. It is also claimed in this paper that the inputs from the grammatical alternations are closely related to the perception of the figure-ground organization, which leads to the conception of container image schema. This paper deals with the four grammatical alternations in Korean, which include floating quantifier constructions, double nominative constructions, subject-to-object raising constructions, and progressive aspect constructions in complex clauses. It is argued that the four marked constructions in Korean are cognitively motivated from their respective corresponding constructions to reflect and embody the cognitive representation of container image schema.
