The sensitive period as a developmental concept is discussed. Observations are made on various problems involved in attempting to explain adult difficulties with second language acquisition by invoking motivational and input factors. (Author/ NQ)

This review describes the prenatal and postnatal development of the human cortex. Neurogenesis, neuronal migration, dendrite maturation, synaptogenesis, and white matter development are discussed. In addition, the concept of "critical" or "sensitive" periods is discussed as well as genetic and environmental influences (Nature-Nurture). The effects…
