Introduction

  • The extended mind explores the boundary between mind and environment.

  • Two common views on mind boundaries:

    • Mind is confined within the skull and skin (internalism).

    • Meaning and cognitive processes can extend beyond the head (externalism).

  • Propose an alternative: Active Externalism, emphasizing the environment's active role in cognition.


Extended Cognition

  • Examines three scenarios of problem-solving involving cognitive tasks:

    1. Mental rotation of shapes to fit into depicted sockets without external aids.

    2. Use of a rotate button on a computer screen for physical manipulation versus mental rotation.

    3. Use of a neural implant for cognitive tasks, equating it to physical manipulation in terms of cognitive load.

  • Conclusion: Cases are similar in cognitive demands; they rely on both internal cognition and external aids.


Examples of Extended Cognition

  • Everyday cognitive tasks often rely on external tools:

    • Using pen and paper for calculations.

    • Physical rearrangement of tiles in games like Scrabble enhances recall (as studied by Kirsh, 1995).

    • The case of Tetris: Physical rotation is quicker than mental rotation demonstrating cognitive aid through physical action.

  • Epistemic actions: Actions that alter the environment to aid cognitive processes (e.g., organizing information).

  • Suggestion: External components can enhance cognition on par with internal processes.


Active Externalism

  • Active Externalism highlights the interaction between humans and their environment as part of cognition.

  • Cognitive systems can include both biological and external entities impacting behavior.

  • Removing the external component decreases cognitive performance, similar to removing brain parts.

  • Differentiates from traditional externalism (Putnam and Burge), where external factors are passive and historical.


Causal Relevance of External Factors

  • External features highly influential in active externalism; they actively affect cognition and behavior.

  • Unlike passive factors where external changes do not affect behavior, active features respond directly to circumstances.

  • Clarification: Importance of environmental supports is essential to explaining cognitive processes.


Case Studies: Otto and Inga

  • Examining belief structures through Otto (who uses a notebook) versus Inga (who relies on natural memory).

  • Otto's notebook serves as an external memory store, paralleling Inga's cognitive processes.

  • Beliefs held by both characters can be explained similarly despite the different physical mediums.


The Role of Language and Social Cognition

  • Language extends cognitive capabilities beyond individual minds, allowing societal interactions.

  • Potential for social relationships to contribute to individual belief systems through trust and reliance.

  • Extends the notion of self, where cognitive boundaries reflect in relationships with others and objects.


Conclusion

  • The extended mind suggests a reconception of cognitive processes extending beyond traditional definitions.

  • Implications for research in cognitive science, philosophy, and moral considerations regarding environments and identity.

  • Questions raised about the limits of cognitive extensions and their implications for personal identity.
