Environmental Effects on Cognitive Abilities

by Robert J. Sternberg (Editor), Elena L. Grigorenko (Editor)

It sometimes seems that it is difficult to pick up a current newspaper or a magazine without it containing a story about some behavioral characteristic for which it has been found that a gene is responsible. Even aspects of behavior that one would feel certain are environmentally controlled are now being attributed in part to the effects of the genes. But genes never act Their effects are always filtered through the environment.

The goal of this volume is to discuss how the environment influences the development and the maintenance of cognitive abilities. It is a successor to the editors' 1997 volume, Intelligence, Heredity, and Environment, and a companion to their new volume, Family Environment and Intellectual A Life-Span Perspective. Taken together, the two-volume set comprises the most comprehensive existing work on the relation between the environment and cognitive abilities.

Psychologists, parents, social workers, educators, and employers are all likely to find this book of interest.

About the author

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.
