TLDR
This is a monumental study of the relatives of 289 persons who lived at Faribault Minnesota State Colony for the Retarded during the years 1911 to 1918—each retardate averaged 25 years of residential care within the institution.Abstract:
This is a monumental study of the relatives of 289 persons who lived at Faribault Minnesota State Colony for the Retarded during the years 1911 to 1918. Information about 82,217 persons is analyzed in this volume—each retardate averaged 25 years of residential care within the institution. The original study was developed in 1910 and was reopened in 1949 by the present investigators. I find it difficult to assess the value of this book for pediatricians. It is undoubtedly a very meaningful report for geneticists, but I would not recommend its purchase by the practicing pediatrician.read more

How Much Can We Boost IQ and Scholastic Achievement
Abstract: Arthur Jensen argues that the failure of recent compensatory education efforts to produce lasting effects on children's IQ and achievement suggests that the premises on which these efforts have been based should be reexamined.

Comparison of the biometrical genetical, MAVA, and classical approaches to the analysis of human behavior.

TL;DR: Although data were often inadequate, the techniques provided new information on the gene action controlling the measures and on their evolution, indicating the unique value of the biometrical approach.

TL;DR: The most exciting direction for genetic research on intelligence is to harness the power of the Human Genome Project to identify some of the specific genes responsible for the heritability of intelligence.

Sex differences in means and variability on the progressive matrices in university students: A meta-analysis
Paul Irwing,Richard Lynn +1 more
TL;DR: A meta-analysis of 22 studies of sex differences in university students of means and variances on the Progressive Matrices disconfirm the frequent assertion that there is no sex difference in the mean but that males have greater variability.

The Raising of Intelligence: A Selected History of Attempts To Raise Retarded Intelligence
TL;DR: Early Intervention and Compensatory Education as discussed by the authors is a classic example of the return of radical empiricism in the field of mental health. But it is not a good fit for the treatment of mental retardation.

X-linked mental retardation: vanishing boundaries between non-specific (MRX) and syndromic (MRXS) forms
TL;DR: Genotype–phenotype correlation studies of affected individuals in XLMR families with MRX gene mutations are necessary to define the criteria of MRX vs MRXS subclassification, and the importance of accurate clinical evaluation is stressed.
