Linguistic structure and the languages-of-thought

Area of Science:

• Cognitive Psychology
• Comparative Psychology
• Linguistics

Background:

• Psychology often studies behavioral capacities independently of the underlying mental systems.
• Connecting behavioral capacities to mental system architecture is a growing area of research.
• The relationship between language structure and human cognition remains a key question.

Purpose of the Study:

• To propose and explore a methodology for linking behavioral capacities to the formal structure of underlying mental systems.
• To bridge linguistic theory and comparative psychology by examining the role of language in cognition.
• To generate hypotheses about distinctively human cognitive traits based on the formal structure of human language.

Main Methods:

• Adopting a methodology that connects observable behavioral capacities to the theoretical format of mental systems.
• Leveraging principles from linguistic theory to inform hypotheses in comparative psychology.
• Analyzing the formal structure of human language to infer cognitive underpinnings.

Main Results:

• The proposed methodology provides a framework for integrating linguistic insights into the study of animal cognition.
• Identifying the formal properties of human language can generate testable hypotheses about human-specific cognition.
• This approach opens new avenues for comparative research on the evolution of cognition.

Conclusions:

• A methodology connecting behavioral capacities and mental system format offers a novel approach in psychology.
• Linguistic theory can significantly inform comparative psychology by elucidating the cognitive functions of language.
• Understanding language structure is crucial for explaining the unique cognitive abilities of humans.
