This volume brings together leading researchers in a major new effort to bridge the historical gap between the domains of ability and personality. The result is a remarkable collection of chapters analyzing critical issues at the interface--style, structure, process, and context. Contributors address: * intelligence and its relation to temperament and character-hierarchical models of cognition and personality; judgmental data in personality research; and structural issues in ability and personality; * intelligence and conation-goal theories; the role of conation in the learning environment; motivation and arousal; * intelligence and style-stylistic preferences; the role of disposition; cognitive style and its measurement; test taking style; and * intelligence and personality in context-regularities of functioning; contextual effects in cultural variation; control and consistency; the concept of "successful intelligence."
