Althen (former foreign student adviser, U. of Iowa) gives advice to foreign visitors to the U.S. that is intended to help them understand the motivations, attitudes, communication styles, and actions of Americans. Emphasizing the interpretation of observed behavior, he covers ways of reasoning and American ideas about politics, family life, education, religion, the media, social relationships, racial and ethnic diversity, male-female relationships, sports and recreation, driving, shopping, personal hygiene, and organizational and public behavior. Over-generalization is an understandable danger in such a work as this, but Althen does make an effort to emphasize that there are variations among Americans, while he concentrates on the similarities.
