The Modular theory of mind proposed by evolutionary psychology
holds that human brains (and, by extention, behavioral and mental
traits) are composed of a number of specialized, domain-specific adaptations.
That is, the brain is essentially a "Swiss Army knife", with specific
tools designed by evolution to cope with specific problems.
Theoretically and empirically, there are very good reasons for this.
1. The specificity of environmental problems in the environment of evolutionary adaptedness.( Devrait pas plutôt dire que : Diversity itself creates opportunities for specialization ?)
2. Successful behavioral/mental adaptation requires facultative responses.
3. The neurophysiology of human mental and behavior traits appears to be quite specific.
Modularity is not to be confused with a lack of a factor of general intelligence.
