Testing the Reference of Biological Kind Terms.

Area of Science:

• Philosophy of Language
• Cognitive Science
• Linguistics

Background:

• Existing research on natural kind terms suggests dual mechanisms for reference determination: descriptive and nondescriptive.
• This has led to theories proposing ambiguity or hybrid models, challenging traditional descriptive and causal-historical theories.
• Many studies rely on referential intuitions, a methodology this paper questions.

Purpose of the Study:

• To investigate the reference determination of natural kind terms by prioritizing usage over intuition.
• To determine if both descriptive and causal-historical elements contribute to the reference of biological kind terms.
• To propose a more flexible framework for understanding the reference of natural kind terms.

Main Methods:

• Rejection of referential intuition as a primary testing method.
• Utilization of elicited production experiments to assess actual linguistic usage.
• Focus on a specific biological kind term to analyze reference determination.

Main Results:

• Experimental results confirm the presence of both descriptive and causal-historical elements in the reference determination of the tested biological kind term.
• Observed contradictions among participants suggest potential issues with experimental design rather than inherent term ambiguity.
• Earlier experiments using novel terms or fantastical scenarios may have yielded unreliable data due to compromised linguistic competence.

Conclusions:

• The assumption that a single theory of reference applies to all natural kind terms should be abandoned.
• Natural kind terms likely encompass a spectrum of reference determination types: descriptive, causal-historical, ambiguous, and hybrid.
• Future research should employ methodologies that test terms with established usage and realistic contexts to ensure linguistic competence.
