The fourth edition of this trusted text preserves the personal appeal of the subject matter and vigorous standards of scholarship that have made the earlier editions so successful. Written in a unified voice, this text features the reader-friendly tone that was established in the first three editions and presents the key findings on intimate relationships, the major theoretical perspectives, and some of the current controversies in the field. Brehm, Miller, Perlman, and Campbell illustrate the relevance of close relationship science to readers' everyday lives, encouraging thought and analysis. The new edition includes more illustrations, tables, and figures that complement the thoroughly updated, new-and-improved text.
