[[John A. Lucy]] has proposed a three-level analysis:
1. '''Semiotic relativity of thought''': "Whether having a code with a symbolic component (versus one confined to iconic-indexical elements) transforms thinking. This would distinguish species that use such a code from those that do not. 2. '''Structural relativity of thought''': Whether "different morphosyntactic configurations of meaning affect thinking about reality." This is the level of analysis that is generally described as '''linguistic relativism''', and distinguishes speakers of different languages. 2. '''Functional relativity of thought''': "Whether using language in a particular way (e.g. schooled) may influence thinking … whether discursive practices influence thinking." This level distinguishes speakers of different backgrounds or in different contexts.
