One of the primary advances for the 21st century is progress beyond the need to defend the findings of behavioral genetic investigations of intelligence. With the advent of developmental behavioral genetics and molecular genetics researchers have taken their discoveries far beyond simple nature/nurture constructs to a finer understanding of how genes and environment intersect to affect cognitive function.

"Behavior Genetics of Cognition across the Lifespan" presents the state of the field in well-documented detail as noted experts examine gene-environment interactions in cognitive function from childhood into old age. Fluidity is at the heart of this coverage: normative and non-normative brain development get equal attention, and statistical, molecular, biological, brain imaging, and neurobiological approaches contribute separately and in combination to the findings.

All major life stages are examined as periods of gene-based cognitive change, including midlife, which until recently has been considered a period for marking time until "real" age-related change occurs. And the book is written so that individual chapters can be as useful on their own as the volume is as a whole. Among the topics covered in depth:

Cognitive abilities in childhood and adolescenceGenetic and environmental influences on intellectual disabilities in childhoodCognition in middle adulthoodGene by environment interplay in cognitive agingDementia: genes, environments, interactionsBrain imaging and cognition

By synthesizing where the field is today--and identifying issues that need further attention--"Behavior Genetics of Cognition across the Lifespan" is a bedrock text for behavioral geneticists, cognitive psychologists and neuroscientists."

Along with psychopathology, cognition has been one of the primary phenotypic focal points of the field of behavior genetics since its inception. Francis Galton's 1874 examination of eminent families in Britain was among the earliest attempts to investigate whether cognitive achievements run in families. This volume presents current methodologies for understanding cognitive abilities that move beyond the outdated nature vs. nurture paradigm. Recent advances in both collection and statistical modeling of twin data, particularly longitudinal twin data, make this an especially advantageous moment to produce a work that presents a collection of the groundbreaking research on cognitive abilities across the lifespan. This volume presents an overview of the current state of quantitative and molecular genetic investigations into the many facets of cognitive performance and functioning across the lifespan.
