Robert J. Sternberg's spectacular research career in psychology had a rather inauspicious beginning. In elementary school he performed poorly on IQ tests, and his teachers' actions conveyed their low expectations for his future progress. Everything changed when his fourth grade teacher, Mrs. Alexa, saw that he had potential and challenged him to do better. With her encouragement, he became a high-achieving student, eventually graduating summa cum laude and Phi Beta Kappa from Yale University. In a gesture of gratitude, Dr. Sternberg dedicated his book, Successful Intelligence to Mrs. Alexa.

Dr. Sternberg's personal experiences with intelligence testing in elementary school lead him to create his own intelligence test for a 7 th grade science project. He happened to find the Stanford-Binet scales in the local library, and with unintentional impertinence, began administering the test to his classmates; his own test, the Sternberg Test of Mental Abilities (STOMA) appeared shortly thereafter. In subsequent years he distinguished himself in many domains of psychology, having published influential theories relating to intelligence, creativity, wisdom, thinking styles, love and hate.

Dr. Sternberg's Triarchic Theory of (Successful) Intelligence contends that intelligent behavior arises from a balance between analytical, creative and practical abilities, and that these abilities function collectively to allow individuals to achieve success within particular sociocultural contexts. Analytical abilities enable the individual to evaluate, analyze, compare and contrast information. Creative abilities generate invention, discovery, and other creative endeavors. Practical abilities tie everything together by allowing individuals to apply what they have learned in the appropriate setting. To be successful in life the individual must make the best use of his or her analytical, creative and practical strengths, while at the same time compensating for weaknesses in any of these areas. This might involve working on improving weak areas to become better adapted to the needs of a particular environment, or choosing to work in an environment that values the individual's particular strengths. For example, a person with highly developed analytical and practical abilities, but with less well-developed creative abilities, might choose to work in a field that values technical expertise but does not require a great deal of imaginative thinking. Conversely, if the chosen career does value creative abilities, the individual can use his or her analytical strengths to come up with strategies for improving this weakness. Thus, a central feature of the triarchic theory of successful intelligence is adaptability-both within the individual and within the individual's sociocultural context.

Scientists Making a Difference is a fascinating collection of first-person narratives from the top psychological scientists of the modern era. These readable essays highlight the most important contributions to theory and research in psychological science, show how the greatest psychological scientists formulate and think about their work, and illustrate how their ideas develop over time. In particular, the authors address what they consider their most important scientific contribution, how they got the idea, how the idea matters for the world beyond academic psychology, and what they would like to see as the next steps in research. The contributors, who were chosen from an objectively compiled list of the most eminent psychological scientists, provide a broad range of insightful perspectives. This book is essential reading for students, researchers and professionals interested in learning about the development of the biggest ideas in modern psychological science, described firsthand by the scientists themselves.
