Resnick (1994) Learning About Life Concepts from Systems thinking ● Self-organization: Order comes from group, not leader ● Emergence: Complex structure that appears from simple pieces ● Decentralized local interactions: The simple pieces act with those around them, not with everything. ● Mutual causality: Two things cause each other ● Levels of organization: There are the pieces and there are patterns made out of the pieces. These are both different levels of analysis Resnick (1994) Learning About Life Heuristics (Rules) to guide us: ● Positive Feedback Isn't Always Negative ● Randomness Can Help Create Order ● A Flock Isn't a Big Bird ● A Traffic Jam Isn't Just a Collection of Cars ● The Hills are Alive Resnick (1994) Learning About Life Heuristics (Rules) to guide us: ● Positive Feedback Isn't Always Negative ● Randomness Can Help Create Order ● A Flock Isn't a Big Bird ● A Traffic Jam Isn't Just a Collection of Cars ● The Hills are Alive Let's try it out! (Hint - this is practice for CPR!) Flocking Birds Real Life Flocking Birds Model of Flocking Birds Let's think about the Heuristics: Positive Feedback? Randomness? Levels? Changing Composition? Interaction with Environment? Fireflies Real Life Fireflies Model of Fireflies Let's think about the Heuristics: Positive Feedback? Randomness? Levels? Changing Composition?

"But Jeremy, I'm a Cognitive Scientist, not a Biologist!" Hutchins (2001) Cognition, Distributed Two main distinguishing features: ● The boundaries of the unit of analysis for cognition may be different depending on what you want to study ● The material environment plays a role in cognitive activity Mantra: "What information goes where, when, and in what form?" Hutchins (2001) Cognition, Distributed ● Distribution of representations in a community ● = different people know different stuff so do different things ● To understand how groups make decisions, reason together, think and create new ideas, we have to understand how they interact ● A jury has different properties than a judge ● Distribution of representations in a brain ● = different brain regions have different properties so do different things ● To understand how the brain functions, we have to understand how regions interact ● A brain has different properties than brain regions. ● (Brain regions have different properties than neurons) That's all.
