Study Notes

Cognitive Science & Scientific Method

Occam's Razor: A principle favoring simpler explanations over complex ones when data interpretations are equal.
Simplicity is a key goal in machine learning, aiming to find the simplest hypothesis that matches sample data.

Multi-disciplinary Perspective in Cognitive Science

Cognitive Science integrates multiple disciplines: Philosophy, Biology, Neuroscience, Psychology, Linguistics, and Artificial Intelligence.
Understanding the mind requires interdisciplinary communication and cooperation rather than exhaustive detailed reconstruction of each component.

Philosophy's Role in Cognitive Science

Philosophy is the oldest discipline, crucial in defining problems, critiquing models, and suggesting research areas.
Employs reasoning, primarily through deductive methods to derive new statements.

The Tale of the Neuroscientist and the Computer

Highlights the importance of mechanistic theory in cognitive neuroscience; understanding brain functions requires more than network interactions.
Demonstrates that extracting necessary components for functioning (like video output in computers) illustrates the need for lesion studies in neuroscience.

Key Takeaways from Cognitive Neuroscience

Cognitive neuroscience is still developing; a mechanistic theory is essential for understanding cognition in the brain.
Development of computer models producing testable hypotheses is necessary.
A multi-disciplinary approach is critical, as neuroscience alone is insufficient for comprehensive understanding.
