ABSTRACT
Benson Ginsburg is a behavioral geneticist with a lively professional interest in wolves. He crosses them with other canines to see which traits of wolf behavior reappear in the hybrids and therefore can be considered to be inherited. But Ginsburg has never lost his early interest in mice, about whose genetic composition so much is now known that one can sometimes identify the specific genes related to specific behavior. Intelligence is marked by a quality of alertness in the totality of one's interactions with the environment. The term "cognitive style" has in recent years been adopted by many psychologists to describe the stable preference shown by any one person for a particular way of organizing and categorizing what he perceives. Given a picture of two native Polynesian adults and a child, the splitters will describe them as "people with no shoes on" whereas the lumpers will describe them as "a family.".
