Ostensive communication, market exchange, mindshaping, and elephants

Area of Science:

• Evolutionary Anthropology
• Comparative Psychology
• Linguistics

Background:

• Human expressive communication exhibits remarkable topic range and type diversity.
• Previous theories often emphasize mindreading as a primary driver of social cognition.
• Market exchange and niche construction are recognized as key human evolutionary factors.

Purpose of the Study:

• To test Heintz & Scott-Phillips's hypothesis linking communication diversity to market exchange and mindshaping.
• To explore the explanatory power of this hypothesis for non-human animal communication.
• To investigate the role of mindshaping over mindreading in complex social interactions.

Main Methods:

• Conceptual analysis integrating theories from economics, anthropology, and cognitive science.
• Comparative analysis of human communication with animal social behavior, specifically elephants.
• Literature review of existing research on niche construction, market exchange, and social cognition.

Main Results:

• The hypothesis suggests that the unique human capacity for extensive market exchange supports a broad range of expressive communication topics.
• Consilience with niche construction theory reinforces the idea that shaping others' minds (mindshaping) is more critical than simply reading them (mindreading).
• This framework offers a potential explanation for the seemingly purposeless, continuous social communication observed in elephants.

Conclusions:

• Heintz & Scott-Phillips's hypothesis provides a novel perspective on the evolution of human communication.
• The proposed link between economic behavior, niche construction, and communication complexity is supported.
• The hypothesis has implications for understanding the evolution of social cognition and communication across species.
