摘要
Psychometricians have discovered a trend showing that IQ scores in children have shown a significant rise over the past 50 years, and scores between white and minority students are converging. This trend, dubbed the Flynn Effect after James Flynn, the social scientist who first documented it, is the focus of this book. Is it possible to compare IQ scores from one generation to the next? Which environmental factors most affect IQ? What kind of intelligence does psychometric tests actually measure? Leading experts in nutrition, psychometric research, sociology and cognitive, social and developmental psychology debate the source of the Flynn Effect, along with the much-discussed dysgenic hypothesis, made popular by Charles Murray in The Bell Curve. This should be useful to those who seek the latest scholarship on intelligence and its measure.

Rising intelligence test scores and narrowing differences in scores between blacks and whites are undeniable facts supported in current scholarly literature. These facts and other phenomena challenge the position that heredity is the primary determinant of intelligence. Neisser, the father of cognitive psychology, provides a fascinating collection of research papers exploring and explaining these issues. In readable and convincing essays, authors such as James R. Flynn, Carmi Schooler, David W. Grissmer, Richard Lynn, and Samuel Preston offer alternative explanations for racial differences on standardized tests. The contributors take on such subjects as the nature and existence of a general or "g" factor of intelligence; nutritional and cultural factors in intellectual development; and the controversial "dysgenic trend." However, the collection does not take itself too seriously, and the contributors spend much time offering critiques of and suggestions to each other. With its refreshing environmental perspective on intelligence, The Rising Curve should sit on the student's or scholar's shelf next to Richard Herrnstein and Charles Murray's The Bell Curve (CH, May'95).
