Handbook of
Developmental Cognitive Neuroscience represents the distillation of the best
this new field has to offer; it also reflects a number of strong biases by the
editors. One such bias is that the field of developmental cognitive
neuroscience must be grounded in basic neurodevelopmental science, particularly
developmental neurobiology. To this end, the first part of this volume
(Fundamentals of Developmental Neurobiology) is devoted to basic studies and
principles of neural development. Here the reader learns about pre- and postnatal
neurogenesis, synaptogenesis, and myelination; the effects of sex hormones on
brain development; and about development of the hippocampus and prefrontal
cortex in particular (given the importance of these regions for cognitive
development). A second bias is our emphasis on the importance of methodological
advances. Thus, the second part of the volume (Methodological Paradigms) is
devoted to describing methods that have proved so important in elucidating
brain-behavior relations in the context of cognitive development. These methods
include behavioral "marker" tasks, along with event-related
potentials (ERPs), functional Magnetic Resonance Imaging (fMRI), and genetic
and computational (neural network) modeling. Over the past several years the
area of neural plasticity has received tremendous attention by both
neuroscientists and behavioral scientists. Indeed, the forces that shape and
mold the brain may well represent the "new" developmental psychology,
albeit a more mechanistic and reductionistic version than offered by previous
generations of developmental psychologists and one that emphasizes development
within a lifespan context. That is, the forces that mold the brain's structure
and physiology are now recognized to operate well into adulthood (see Tanapat,
Hastings, and Gould, chapter 7, this volume). To this end, the third part
(Neural Plasticity of Development) is devoted to a discussion of this area,
emphasizing both normative and atypical aspects of development.
