Research Abstract

This study has analyzed the political (dis)similarity judgment data using the geometric modeling in cognitive psychology and provided a perspective to analyze the cognition of political differences in the spatial modeling of politics. At the same time, this new perspective has enabled us to revise and broaden the existing theory of party coalition that is focused either on office-seeking or policy-seeking.
