How Domain general mechanisms can evolve: Problem: How could domain general mechanisms evolve if they don’t solve any particular problem? Answer: They could evolve if they made it easier to attain evolutionary goals like survival and reproduction. But modules do that as well. What’s so special about domain general mechanisms? Answer: Domain general mechanisms allow us to take in non-recurrent and rapidly changing features of the environment into account. Remember, domain-specific modules evolved because they solved problems that were recurrent over evolutionary time. Rapidly approaching objects and snakes were recurrent problems, and humans

Unformatted text preview: evolved modules that respond to them. So there is an automatic, modular, reflexive, low road fear response to these events. However, the domain general mechanism allows us to think about the context much more broadly (Is the object really going to hit me? Is the snake safely confined to a cage?). And we can try to think up new ways to deal with these problems beyond just reflexively respond by jumping away (Get a gun; call 911; realize there is no real problem even though we feel the fear). Hierarchical model of motivation showing relationships between domain-specific and domain-general mechanisms....
