Abstract

Though we can describe the characteristics of mental growth in childhood and mental decline in old age, there are great difficulties in demonstrating the main causal factors. A stimulating or a deprived environment has greater effects on the development of intelligence than used to be believed; but there are also strong grounds for recognizing that genetic differences, which underlie biological maturation and decay, determine human capacities to a large extent.
