Surveys show that our growing concern over protecting the environment is accompanied by a diminishing sense of human contact with nature. Many people have little commonsense knowledge about nature¿¿¿are unable, for example, to identify local plants and trees or describe how these plants and animals interact. Researchers report dwindling knowledge of nature even in smaller, nonindustrialized societies. In The Native Mind and the Cultural Construction of Nature, Scott Atran and Douglas Medin trace the cognitive consequences of this loss of knowledge. Drawing on nearly two decades of cross-cultural and developmental research, they examine the relationship between how people think about the natural world and how they act on it and how these two phenomena are affected by cultural differences.
