This book is ideal for those interested in motivational concepts who are seeking to tie together a variety of theoretical approaches. The book uses a topical approach and covers a wide range of material from both animal and human behavior. Wherever possible, the book seeks to tie together different areas of research to identify common themes. It explores basic biological ideas and the concepts of reinforcers and incentive motivation, then moves to aversive motivation, with an emphasis on human motivation. Chapters discuss aggression and altruism, motivation in personality theory, attitudes and interpersonal attraction. The concluding chapter examines motivation in the workplace, sports and persuasion.
