Handedness and intellectual achievement: An even-handed look
TLDR
The data support the earlier finding that ambidextrous individuals perform more poorly than left- or right-handers, especially on subscales measuring arithmetic, memory, and reasoning, and extend that finding to adults.About:

The evolution and genetics of cerebral asymmetry
TL;DR: It is suggested that, in behavioural, neurological and evolutionary terms, it may be more profitable to examine the degree rather than the direction of asymmetry, because a minority of individuals reverse or negate the dominant asymmetry.

TL;DR: It is argued that the same evolutionary mechanisms should apply across geographical regions to maintain the roughly 1:10 ratio, while cultural factors, such as pressure against left-hand use, moderate the magnitude of the prevalence of left-handedness.

Nature's Experiment?: Handedness and Early Childhood Development
TL;DR: Using a large, nationally representative sample of young children, it is found that the probability of a child being left-handed is not significantly related to child health at birth, family composition, parental employment, or household income, and there is robust evidence thatleft-handed (and mixed-handed) children perform significantly worse in nearly all measures of development than right-handed children.

Cognitive sex differences and hemispheric asymmetry: A critical review of 40 years of research.
TL;DR: A systematic literature review showing that cognitive sex differences often emerge in the absence of sex differences in hemispheric asymmetry, implying the two phenomena are at least partly independent of each other.

Reading, writing and speech problems in children.
TL;DR: The writer gives an account of his well-known work on disorders of the language faculty in children, and gives the results of therapeutic efforts based on this work, and shows that many children with speech defects have derived benefit.

Handedness and Brain Asymmetry: The Right Shift Theory
TL;DR: This book discusses the Right Shift Theory of Handedness, the Theory of an Agnosic RS+ Gene, and its applications in Speech, Phonology and Varieties of Dyslexia.

Sex differences in intelligence: Implications for education.
TL;DR: A psychobiosocial model that is based on the inextricable links between the biological bases of intelligence and environmental events is proposed as an alternative to nature-nurture dichotomies as discussed by the authors.
